It defaults to -mips2 if -mips1 has not also been specified. Unless specified in the description, options apply to all three compilers. OPTIONS -mips1 Generates code using the instruction set of the R2000/R3000 RISC architecture, and searches for mips1 libraries/objects at link- time. Defaults to -o32. -mips2 Generates code using the MIPS II instruction set (MIPS I + R4000 specific extensions), and searches for mips2 libraries/objects at link-time. Defaults to -o32. -- In XPG4 mode, standard utilities that accept operands but do not accept options, recognize the -- characters as the first argument to be discarded. This lets portable applications shield their operands from arbitrary options that the implementation may provide as an extension. For example, if the standard utility foo is listed as taking no options, and the application needed to give it a pathname with a leading hypen, it could safely do it as foo -- -myfile and avoid any problems with -m used as an extension. -66 (f77 only) Suppresses extensions that enhance FORTRAN 66 compatibility. -ansiE (CC only) Issues error messages for use of non-standard features in ANSI/ISO C. -ansiW (CC only) Issues warning messages for use of non-standard features in ANSI/ISO C. This is the default with the -ansi flag. -ansi (ANSI/ISO C only) Pure ANSI/ISO C. The symbols _MIPS_FPSET, _MIPS_ISA, _MIPS_SIM, _MIPS_SZINT, _MIPS_SZLONG, _MIPS_SZPTR, _LANGUAGE_C, __sgi, __unix, __host_mips, _MODERN_C, __DSO__, _SYSTYPE_SVR4, __mips, _MIPSEB, __STDC__, and _CFE are defined to the preprocessor. The symbol __ANSI_CPP__ is defined, and ANSI/ISO trigraphs are processed by default. NOTE: When compiling in pure ANSI/ISO mode (-ansi), several standard UNIX symbols (such as environ and end) may only be referenced by their ANSI/ISO compliant counterparts (such as _environ and _end). The type long long is allowed, but results in a warning in -ansi mode. To take advantage of this type in libraries that refer to __int64_t and __uint64_t, you must define the macro __LONGLONG on the command line; otherwise, __int64_t and __uint64_t are defined as structs. See the ANSI C Transition Guide for more information. -ansiposix (ANSI/ISO C only) Specifies the same compilation environment as -ansi with the additional preprocessor definition of _POSIX_SOURCE. This is a pure ANSI/ISO environment, and __STDC__ is defined with this option as well as with the -ansi option. WARNING: This option is obsolete and will be removed in future releases. -automatic (f77 only) Places local variables on the runtime stack. The same restrictions apply for this option as they do for the automatic keyword. This is the default. -avoid_gp_overflow Asserts assorted flags that are intended to avoid GOT overflow. -backslash (f77 only) Treats the backslash character as a normal character instead of an escape sequence character. For example, when this option is specified, the sequence \t is treated as two separate characters instead of a single <TAB> character. -bytereclen (f77 only) Record lengths used for unformatted direct I/O are specified as the number of bytes in a record. By default, record length specifications are interpreted as the number of 4-byte words in a record. If the main routine for a mixed C and Fortran program is written in C, and Fortran unformatted direct I/O will be performed by the program, the /usr/include/cmplrs/fioflags.h header file must be included by the C main program and the OLD_RL flag must be set as directed by the header file. -c Suppresses the loading phase of the compilation, and produces an object file. -cckr (CC only) Specifies the traditional K&R/Version7 C with SGI (and some like ANSI/ISO C) extensions, including function prototypes, void, void*. The following symbols are defined to the preprocessor: _MIPS_FPSET _MIPS_ISA _MIPS_SIM _MIPS_SZINT _MIPS_SZLONG _MIPS_SZPTR __EXTENSIONS__ LANGUAGE_C _LANGUAGE_C __INLINE_INTRINSICS sgi __sgi unix mips host_mips __unix __host_mips _SVR4_SOURCE _MODERN_C _SGI_SOURCE __DSO__ SYSTYPE_SVR4 _SYSTYPE_SVR4 _LONGLONG __mips _MIPSEB MIPSEB _CFE -cfront (CC only) Causes the compiler to accept constructs that were accepted by previous cfront-based compilers, such as OCC, but which are not accepted in the ANSI/ISO standard. -chararg1 (f77 only) Counts each character argument as only one argument. For subroutines accepting a variable number of arguments, the default is to count all arguments on the argument stack. This means that for each character argument, the count is two because both the address of the character argument and its length are put on the argument stack. -common (CC only) The declaration int i; in multiple files at file level is merged. Without it, ANSI/ISO C generates a warning (from ld(1)) about duplicate definitions. When C and Fortran compiled objects are linked together and an ANSI C defined variable should be located at the same address as a Fortran common block, you must compile the C source with the -common flag. When specifying traditional K&R/Version7 C (for example, -cckr), this option is ignored. The ANSI/ISO C Strict-Ref/Def-initialization model is relaxed to the traditional IRIX Relaxed Ref/Def model (see the ANSI/ISO C Standard for information on this model). -cord Runs the procedure rearranger, cord(1), on the file created after linking. This improves the paging and caching performance of the program's text. The output of cord(1) is left in the file specified by the -o output option or a.out by default. Use the -feedback option to specify the feedback file. If no -feedback file is specified, then outfile.fb is the default. +d (CC only) Suppresses expansion of inline functions. Copies of inline functions are emitted as external out-of-line functions in each compilation unit where they are called. These are marked so that the linker silently accepts duplicate symbols and resolves all of the calls to one copy of the function, and removes all other copies from the executable. -ddopt (f77 only) Specifies the data dependence optimization pass. An option indicating that the global optimizer is to be run (-O, -O2, -O3) must also be specified. This optimization pass is experimental and may not be supported. -dollar (CC only) Allows the dollar sign ($) as a character in C identifiers, including the leading character of an identifier. This option is provided for compatibility purposes, and its use is not recommended. -expand_include (f77 only) Expands all include statements in the FORTRAN listing file. This option must be specified with the -listing option. -exceptions (CC only) Invokes an exception handling compiler with a different front end than the standard 32-bit compiler. If this option is not specified on the command line, the CC driver continues to invoke the standard 32-bit compiler. If you want to use exception handling, it is recommended that you recompile all of your code using the -exceptions option. Generally, code with exception handling and code without exception handling cannot be mixed. See the release notes for the actual restrictions. This option should be used with caution. -feedback <file> Specifies the feedback file(s) to be used with the -cord option. This file can be produced by using prof(1) with its -feedback option from an execution of the instrumented program produced by pixie(1). Multiple feedback files can be specified with multiple -feedback options. -float Uses single-precision floating-point except when specified in function arguments. In the following example, a and b are promoted to double and a double-precision multiply is done, followed by a conversion back to single-precision for the assignment to c: float a; int b; float c; c = a * b; The -float option is ignored in all ANSI/ISO C conformance modes and has effect only in -cckr mode. ANSI/ISO C uses single precision floating-point operations where allowed by the standard. If the -float option is specified, b is promoted to single-precision, and a single-precision multiply is done. This option does not affect float and double argument passing; float function arguments are promoted to double unless function prototypes are used. Unappended floating-point constants are cast to single precision values in subexpressions with no double (or long double) operands. -framepointer (f77 only) Asserts the requirement of frame pointer for all procedures defined in the source file. -fullwarn Executes various extra checks and produces additional warnings that are suppressed by default. This option is recommended for all compiles during software development. -gn Specifies options for producing debugging information. n can be one of the following: 0 Does not produce debugging information for symbolic debugging. This is the default. 2 Produces additional debugging information for full symbolic debugging and does not perform optimizations that limit full symbolic debugging. These options override the following optimization options: -O, -O1, -O2, -O3. 3 Produces additional debugging information for symbolic debugging of fully optimized code. This option makes the debugger inaccurate. This option can be used with the following optimization options: -O, -O1, -O2, -O3. Specifying -g without a debug level is equivalent to specifying -g2. -h path Specifies the directory (path) where the name is found. -j Compiles the specified source programs, and creates ucode object files in corresponding files appended with .u. -k (f77 only) Passes options that start with a -k to the ucode loader. This is used to specify ucode libraries (with -kl x) and other ucode loader options. -keep Builds intermediate compilation files named after the corresponding source files. The file is appended by a letter appropriate for the type of intermediate file (for example, the front end generates a binary intermediate .B file). These intermediate files are never removed even when a compilation pass encounters a fatal error. -ko output Specifies the output file created by the ucode loader (output). This file is not removed. If this file is compiled, the object file is named output appended with .o. -kpicopt (f77 only) Requests uopt to perform the special treatment for global variables to optimize their program accesses regardless of the shared/nonshared compilation mode. -l library In XPG4 mode, searches the library named lib.IRlibrary.a. A library is searched when its name is encountered, so the placement of the -l operand is significant. -m (f77 only) Applies the M4 preprocessor, m4(1), to each RATFOR source file before transforming it with the ratfor(1) preprocessor. The temporary file created for the output is appended with .p. This temporary file is removed unless the -K option is specified. -mp (CC only) Enables the multiprocessing directives. (Requires Power C.) -nocpp (CC only) The C macro preprocessor is not run on C and assembly source files before compiling. This option is ignored when compiling a .i file. -noexpopt (f77 only) Exponential operation is not optimized. This option achieves the same precision as releases prior to 4D1-4.0 without using the exponentiation optimization. The new optimization might present some precision differences (which do not necessarily mean less accuracy) in double precision exponential operations. -nofilt (CC only) Disables filtering of back end and linker error messages through a filter that demangles C++ external names. -nokpicopt Specifies that uopt does not perform the special treatment for global variables to optimize their program accesses under shared compilation. -non_shared (CC only) Specifies that the compiler build a non-shared object. This is the opposite of specifying -KPIC. Using the -non_shared option causes the linker to search the nonshared subdirectory of each default library search directory (see the ld(1) man page). The linker defaults the archive extensions to .a instead of .so. The appropriate non-shared library images must be installed. Programs built with the -non_shared option are not portable across platforms. -nostdinc (CC only) Does not search for #include files in the standard directory (/usr/include). -old_rl (f77 only) Same functionality as the -bytereclen option which should be used instead of -old_rl. -o output (CC only) Specifies the final output file, output. The file a.out is undisturbed. +p +pp (CC only) The 32-bit compiler enables anachronisms and cfront bug-compatibility support by default (see the -anach and -cfront options). The +p option turns off support for C++ anachronisms. The +pp option turns off support for both anachronisms and cfront bug-compatibility. -pca [list][keep] (CC only) Runs the pca(1) preprocessor to automatically discover parallelism in the source code. This also enables the multiprocessing (-mp) directive. There are two optional arguments: list, Runs pca and produces a .L listing file. It explains which loops were parallelized and if not, why. keep Runs pca and produces the listing file. Creates a transformed multiprocessed C intermediate file appended with a .M. (Power C only.) -pedantic (CC only) In ANSI/ISO preprocessing mode, warns that the #ident preprocessor directive is non-standard except in -cckr mode when the directive is silently ignored. This directive is a System V extension, which by default is silently ignored. -show (CC only) Prints the passes as they execute, their arguments, and their input and output files. -signed (CC only) Causes all char declarations to be signed char declarations. By default they are treated as unsigned char declarations. -sopt[,option][,option]... Invokes the source-to-source optimizer, copt(1) or fopt(1), on the indicated source file(s). This is distinct from the standard global optimizer which is invoked with one of the following options: -O, -O2, or -O3. Additional options can be passed to -sopt by using a comma-separated list, but the options passed by default cannot be changed (use cc -sopt -show or f77 -sopt -show to see what is passed by default). See the copt(1) and fopt(1) man pages for more details. -t [options] Select a name to use for a particular pass, startup routine, or standard library. These arguments are processed from left to right so their order is significant. The following table lists the possible options: Name Character include h ujoin j uld u usplit s umerge m uopt o ugen c as0 a as1 b ld l [m]crt[1n].o r The following are available for C only: preprocessor p pca K (Power C only) mpc M (Power C only) cfe f The following are available for Fortran only: cpp p pfa K fcom f libF77.a F libI77.a I libU77.a U libisam.a S libm.a M cord z Although cc or f77 can be used to compile source files in other languages (such as Pascal), only the name used for the front end of the C or Fortran compiler is selected by the -tf option. f77 Usage notes: When the -B option is encountered, the selection of names takes place using the last -h and -t options. You must use all three options together. For example, -tc -h. -B directs the compiler to use the ugen executable in the current directory. Any of the -g options must precede all -B options because they can affect the location of runtimes and what runtimes are used. If no -t argument has been processed before the -B argument, then a -B string is passed to the loader to use with its -l x arguments. For example, to use /tmp/libI77.a.patch instead of the standard runtime I/O library /usr/lib/nonshared/libI77.a, the program must be linked using the -t I -h /tmp -B .patch options. The F, U, I, S, M, and n options affect compiling with the -non_shared option. -trapuv Forces all uninitialized stack, automatic and dynamically allocated variables to be initialized with 0xFFFA5A5A. When this value is used as a floating point variable, it is treated as a floating point NaN and it will cause a floating point trap. When it is used as a pointer, an address or segmentation violation will likely occur. Default OFF. -u (f77 only) Makes the default type of a variable undefined, rather than using the default FORTRAN rules. -use_readwrite_const Puts const qualified variables and string literals in a readable and writable data section. -use_readonly_const (CC only) Puts string literals and file-level (static, common, or external) const qualified initialized variables into a .rodata section to separate these objects from data likely to be modified. This is the default. However, if you really want constants to not be writable, then in addition to specifying -use_readonly_const you must also specify -G0 -rdata_shared, because by default the linker will make .rodata and gp-relative sections be writable. -usefpidx (f77 only) Forces the compiler to use the floating point DO loop variable as the loop counter. This is contrary to the ANSI standard but maintains backward compatibility with the 4D1-3.3 release. -v (CC) Same as -fullwarn (verbose warnings). The old definition of -v (prints the compiler passes) is invoked with the -show option. (F77) Print the passes as they execute and their input and output. -version Displays the version number of the compiler. The compiler will not be run if this flag is used. -vms_cc (f77 only) Uses VMS FORTRAN carriage control interpretation on unit 6. See the /usr/include/cmplrs/fioflags.h file when the main program is written in C. -vms_endfile (f77 only) Writes a VMS endfile record to the output file when ENDFILE statement is executed and allows subsequent reading from an input file after an endfile record is encountered. See the /usr/include/cmplrs/fioflags.h file when the main program is written in C. -vms_library (f77 only) Treats subroutines and functions starting with LIB$, OTS$, and SMG$ as VMS runtime library routines which take a variable number of arguments. This is accomplished by adding an argument count as the hidden first argument in the actual argument list. Normal FORTRAN routines that do not take a variable number of arguments and do not have an argument count as the first argument in the formal argument list, should not be named as above when used with this compilation option. -vms_stdin (f77 only) Allows rereading from stdin after EOF has been encountered. See the /usr/include/cmplrs/fioflags.h file when the main program is written in C instead. -w[n] Suppresses warning messages. n can be one of the following: 0 (f77 only) Does not suppress the warning message for unused variables. 1 (f77 only) Suppresses the warning message for unused variables (but permits other warnings unless -w is specified. This is the default. 2 Warnings are counted as errors. 66 (f77 only) Suppresses only FORTRAN 66 compatibility warnings messages. -woff all (CC only) Suppresses warning messages. -woff numberlist (CC only) Suppresses warnings in ANSI/ISO C. All warnings have been given a number: the number appears immediately after the word Warning in the warning text, and is larger than 1000 (to make warning numbers different from those in an earlier version of the compiler). The numberlist is a comma-separated set of 1 or more numbersets. A numberset is either a simple integer or a pair of integers separated by a hyphen. Examples: -woff " 1527" suppresses warning 1527. -woff " 1527- 1570" suppresses warnings 1527 through 1570. -woff 1600- 1700,1705-1790 suppresses numbers 1600 through 1700 and 1705 through 1790. -xansi (ANSI/ISO C only) Specifies ANSI/ISO C. See the symbol definitions in the -cckr option description. Note that __STDC__ is defined, __EXTENSIONS__ is defined and adds many symbols into the namespace, and __INLINE_INTRINSICS is defined and may cause some intrinsic <math.h>, <stdio.h>, <string.h>, and <curses.h> library routines to be inlined. Such inlined routines may not set errno in accordance with the strict ANSI/ISO C standard requirements. -xansi is the default used by the compiler unless the environment variable SGI_CC is set (see the introductory remarks of this man page). -xgot Specifies a 32-bit offset in the Global Symbol Table (GOT). By default, addresses are loaded out of the GOT using a 16-bit offset from a context pointer. The default size of the GOT is limited to 64K bytes or about 8K worth of symbols, 16K for -o32 compiled objects. This can sometimes result in a GOT overflow message. Use of the -xgot option allows the GOT to contain up to 1G of entries; however, the resulting executable will be somewhat larger and slower. -xgot is a synonym for -TENV:large_GOT. A better solution for "GOT overflow" problems is to compile the objects without the -xgot option and to link using the -multigot option, described in ld(1). For more information about the GOT, the -xgot option and some important notes about its use, see the dso(5) man page (the FAQ section, "What should I do about a GOT overflow?"). -B string Appends string to all names specified by the -t option. If no -t option has been processed before the -B option, the -t option is assumed to be hpKfjusmocablrnyz. This list designates all names. If no -t argument has been processed before the -B then a -B string is passed to the loader to use with its -l x arguments. Sometimes a more convenient way to get a string appended to all archive library names is to use the ld -Bstring option, which may be passed via the -Wl,-Bstring option. Invoking the compiler with a name of the form cc string has the same effect as specifying a -B string option on the command line. -C (f77 only) See the -DEBUG:subscript_check option description in the DEBUG_group(5) man page. -D name=def -D name Define the name to the C macro preprocessor, as if by #define. If no definition is given, the name is defined as "1". -E Runs only the C macro preprocessor files (without considering suffixes), and sends the result to the standard output. The resultant output will contain line directives. This option overrides the -nocpp option. -F (f77 only) Applies the RATFOR preprocessor to relevant files and puts the result in files appended by .f. (No .o files are created.) -G num Specifies the maximum size, in bytes, of a data item that is to be accessed from the global pointer. num is assumed to be a decimal number. If num is zero, no data is accessed from the global pointer. The default value for num is 0 for shared compiles and 8 for non-shared compiles. Data stored relative to the global pointer can be accessed by the program quickly, but this space is limited. Large programs may overflow the space accessed by the global pointer at load time. If the loader gives the error message Bad -G num value, recompile with -G 0. One must usually use the same value of this switch for compiling all files that comprise a program executable or DSO. -H c (f77 only) Halts compiling after the pass specified by the character c, producing an intermediate file for the next pass. c can be fjusmoca (see the -t option for argument definitions). It selects the compiler pass in the same way as the the -t option. If this option is used, the symbol table file produced and used by the passes is the last component of the source file appended with .T and is not removed. -I The /usr/include file is not searched for #include files. This option will be phased out in a future release; specify -nostdinc instead. -I dir #include files whose names do not begin with / are sought first in the file directory, then in directories specified in -I options, and finally in the standard directory (/usr/include). -K (f77 only) Uses the standard algorithm for generating file names with the conventional suffix for the type of file (for example, .B for binary ucode produced by the front end) instead of putting intermediate files in /tmp or TMPDIR. These intermediate files are never removed even when a pass encounters a fatal error. When ucode linking is performed and the -K option is specified, the basename of the files created after the ucode link is u.out by default. If -ko output is specified, the basename of the object file is output with the appropriate suffix appended at the end if output has no suffix. -KPIC Generates position-independent code (PIC). This is the default and is needed for programs linking with dynamic shared libraries. If you do not want to generate PIC code, specify -non_shared on the command line. -L directory In XPG4 mode, searches for libraries named in directory before searching the default location. Directories are searched in the specified order. Multiple instances of -L options can be specified. -MDupdate filename While compiling, updates filename to contain header, library, and runtime make(1) dependencies for the cc output file. cc -MDupdate updates only lines that end with a distinctive make comment and begin with the name of the output file followed by a colon. The standard option used with make(1) is the following: -MDupdate Makedepend -M Runs only the macro preprocessor on the named C programs, requesting it to generate make dependencies and sends the result to standard output. -N[qxscelnC]nnn (f77 only) Increases size of static tables in the compiler. The compiler displays a warning message if tables overflow and will recommend that you specify one or more of the following flags: q Maximum number of equivalenced variables. Default is 2000. x Maximum number of external names (common block names, subroutine and function names). Default is 3000. s Maximum number of statement numbers. Default is 1000. c Maximum depth of nesting for control statements (such as DO loops). Default is 50. e Maximum expression tree depth. Default is 400. l Maximum number of labels. Default is 125. n Maximum number of local names. Default is 8191. C Maximum number of continuation lines. Default is 99. -O3 Creates a ucode object file for each C, FORTRAN 77, or RATFOR source file appended with .u. The newly created ucode object files, the ucode object files specified on the command line, the runtime startup routine, and all of the runtime libraries are ucode linked. Optimization is done on the resulting ucode linked file and then it is linked as normal producing an a.out file. No resulting .o file is left from the ucode linked result. You cannot specify -c with the -O3 option. Instead, specify the -j option. -Olimit num Specify the maximum size, in basic blocks, of a routine to be optimized by the global optimizer. If a routine has more than this number of basic blocks, it is not optimized and a message is printed. An option specifying that the global optimizer is to be run (-O, -O2, -O3) must also be specified. num is assumed to be a decimal number. The default value for num is 1000 basic blocks. -O n The main optimization level, specifying the basic level of optimization desired. n can be one of the following: 0 Turns off all optimizations. This is the default. 1 Turns on local optimizations that can be done quickly. 2 Turns on extensive optimization. The optimizations at this level are generally conservative, in the sense that they (1) are virtually always beneficial, (2) provide improvements commensurate to the compile time spent to achieve them, and (3) avoid changes which affect such things as floating point accuracy. 3 Turns on aggressive optimization. The optimizations at this level are distinguished from -O2 by their aggressiveness, generally seeking highest-quality generated code even if it requires extensive compile time. They may include optimizations that are generally beneficial but occasionally hurt performance. If no value is specified for n, 2 is assumed. -P Runs only the C macro preprocessor. Puts the result for each source file (by suffix convention, i.e., .c and .s) in a corresponding .i file. The .i file has no # lines in it. -R (f77 only) Uses any remaining characters in the argument as RATFOR options whenever processing a .r file. The temporary file used as the output of the RATFOR preprocessor is that of the last component of the source file with a .f substituted for the .r. This temporary file is removed unless the -K option is specified. -S Compiles the specified source programs and leaves the symbolic assembly language output in corresponding files appended with .s. -U (f77 only) Does not fold cases. f77 is usually a case- insensitive language (for example, a is equivalent to A). The -U option causes f77 to treat uppercase and lowercase separately. The compiler only recognizes keywords in lowercase when this flag is used. -U name Removes any initial definition of name. -Wc,arg1[,arg2]... (f77 only) Passes the argument(s) argi to the compiler pass c. c is one of pfjusmocablKyz. c selects the compiler pass in the same way as the -t option (see the -t option decription). This switch is not standard and may not be supported across product lines. -Wf, -Yc (CC only) Removes calls to empty user-defined constructors and destructors. This option improves the quality of code generated and the runtime performance. This option could have undesirable side effects on code compiled with the -exceptions option and should be used with extreme caution. -Wx,[-G [num],-v, -A, -K] Treats any argument following -Wx, as if it were an svr3 cc option. -Xcpluscomm Processes C++ style comments (// ). By default, // is not treated as a comment introduction. With this option, C++ comment rules are applied.
