3.3.3 Compile-Time and Link-Time Options
The following table lists the options that must be specified both at
link-time and at compile-time.
Table 3-4 Compile-Time and Link-Time Options
|
|
|
–fast
|
Selects the optimum combination of compilation options for speed of executable code.
|
|
-fopenmp
|
Equivalent to -xopenmp=parallel.
|
|
–m32|–m64
|
Specifies the memory model for the compiled binary object.
|
|
–mt
|
Macro option that expands to –D_REENTRANT
–lthread.
|
|
-std
|
Specify C++ language version and compatibility mode.
|
|
–xarch
|
Specifies the instruction set architecture.
|
|
–xautopar
|
Turns on automatic parallelization for multiple processors.
|
|
–xhwcprof
|
(SPARC) Enables compiler support for hardware counter-based profiling.
|
|
–xipo
|
Performs whole-program optimizations by invoking an interprocedural analysis component.
|
|
-xipo_build
|
Reduce compile time by avoiding optimizations during the initial pass through the compiler,
optimizing only at link time.
|
|
-xlinker
|
Specify linker options
|
|
–xlinkopt
|
Performs link-time optimizations on relocatable object files.
|
|
–xmemalign
|
(SPARC) Specifies the maximum assumed memory alignment and behavior of misaligned data
accesses.
|
|
–xopenmp
|
Supports the OpenMP interface for explicit parallelization including a set of source code
directives, runtime library routines, and environment variables
|
|
–xpagesize
|
Sets the preferred page size for the stack and the heap.
|
|
–xpagesize_heap
|
Sets the preferred page size for the heap.
|
|
–xpagesize_stack
|
Sets the preferred page size for the stack.
|
|
-xpatchpadding
|
Reserve an area of memory before the start of each function.
|
|
–xpg
|
Prepares the object code to collect data for profiling with
gprof(1).
|
|
–xprofile
|
Collects data for a profile or uses a profile to optimize.
|
|
-xs
|
(Oracle Solaris) Link debug information from object files into executable.
|
|
–xvector=lib
|
Enables automatic generation of calls to the vector library functions.
