Includes symbols in the executable. If the optimization level is -xO3 or lower, some optimizations may be disabled when -g is present. At -xO4 or higher, full optimization is performed, even when -g is present.
A convenience option, this switch selects several other options that are described in this file.
Perform optimizations across all object files in the link step:
At -xipo=2, the compiler performs inter-procedural aliasing analysis as well as optimization of memory allocation and layout to improve cache performance.
Specifies the LP64 model: 32-bit ints, 64-bit longs and pointers types.
Enables OpenMP language extension.
Set the preferred page size for running the program.
Allows the compiler to perform type-based alias analysis at the specified alias level:
Control the level of searching that the compiler does for prefetch opportunities by setting n to 1, 2, or 3, where higher numbers mean to do more searching. The default for Oracle Solaris Studio C and Oracle Solaris Studio C++ is 1. The default for Oracle Solaris Studio Fortran is 2.
Links in a library of "object caching" memory allocation routines which can be faster than those found in libc.

This section contains descriptions of flags that were included implicitly by other flags, but which do not have a permanent home at SPEC.
Allows the compiler to assume that your code does not rely on setting of the errno variable.
Sets the maximum assumed data alignment:
Selects faster (but nonstandard) handling of floating point arithmetic exceptions and gradual underflow.
Controls simplifying assumptions for floating point arithmetic:
Evaluate float expressions as single precision.
Turns off all IEEE 754 trapping modes.
Allows the compiler to perform type-based alias analysis at the specified alias level:
Substitute intrinsic functions or inline system functions where profitable for performance.
Analyze loops for inter-iteration data dependencies, and do loop restructuring. Loop restructuring includes loop interchange, loop fusion, scalar replacement, and elimination of "dead" array assignments.
Use inline expansion for math library, libm.
Select the optimized math library.
Specify optimization level n:
Selects options for architecture, chip timing, and cache sizes. These can also be controlled separately, via -xarch, -xchip, and -xcache, respectively. A wide variety of targets can be selected, including ultra3, ultra3cu, ultra3i, ultra3iplus, ultra4, ultra4plus, ultraT1, ultraT2, sparc64vi. In each case, appropriate options are selected for architecture, chip timing, and cache size to match that target.
If -xtarget=native is selected, options that are appropriate for the system where the compile is being done.
The default is -xtarget=generic, which sets the parameters for the best performance over most 32-bit platform architectures.
On Solaris SPARC systems, the default pointer size with -xtarget=native is 32-bit.
Specifies which instructions can be used. Among the choices are:
xcache defines the cache properties for use by the optimizer. It can specify use of default assumptions ("generic"); use of whatever the compiler can assume about the current platform ("native"); or an explicit description of up to three levels of cache, using colon-separated specifiers of the form si/li/ai, where:
xchip determines timing properties that are assumed by the compiler. It does not limit which instructions are allowed (see xtarget for that). Among the choices are:
Assume data is naturally aligned.
Sets the IEEE 754 trapping mode to common exceptions (invalid, division by zero, and overflow).
Pad local variables, for better use of cache.
Allow the compiler to transform math library calls within loops into calls to the vector math library. Specifying -xvector is equivalent to -xvector=lib.
MTEXCLUSIVE
If set to "Y", additional memory allocation buckets will be created, so that threads will not need to share buckets
unless more than 2*NCPUS threads are created. This variable is used by mtmalloc.
OMP_NUM_THREADS
Sets the number of threads to use in OpenMP parallel regions.
OMP_PROC_BIND
Sets the thread affinity policy to be used,
false allows threads to move among other behavior, true
directs threads to stay where they are placed.
OMP_PLACES
Binds threads in an OpenMP program to the virtual processors.
OMP_DYNAMIC
If true, allows for the dynamic adjustment of the number of threads
for parallel regions. False disables dynamic adjustment.
OMP_WAIT_POLICY
Sets the wait policy, active means threads consume processor
cycles while waiting, passive means consume minimal processor cycles
while waiting.
SUNW_MP_PROCBIND
Binds threads in an OpenMP program to the virtual processors enumerated in the assignment. Can also be set to TRUE,
which casues threads to be bound in a round-robin fashion.
SUNW_MP_THR_IDLE
Specifies whether idle threads should SLEEP or SPIN.
STACKSIZE=<n>
Set the size of the stack (temporary storage area) for each slave thread of a multithreaded program.
ulimit -s <n>
Sets the stack size to n kbytes, or "unlimited" to allow the stack size to grow without limit.
Note that the "heap" and the "stack" share space; if your application allocates large amounts of memory on the heap,
then you may find that the stack limit should not be set to "unlimited". A commonly used setting for SPEC CPU2006 purposes
is a stack size of 128MB (131072K).
