This macro indicates that the benchmark is being compiled on a SPARC/Solaris system.
SPEC_CPU_SOLARIS is used so that SUN submitters don't have to bother specifying SPEC_CPU_HAVE_BOOL. It sets HAVE__BOOL, and also includes alloca.h.
Enables portability changes for Solaris
This flag can be set for SPEC compilation for Solaris using default compiler.

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.
Selects options appropriate for the system where the compile is taking place, including architecture, chip, and cache sizes. (These can also be controlled separately, via -xarch, -xchip, and -xcache, respectively.)
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:
Specifies which instructions can be used. Among the choices are:
Enables the use of the fused multiply-add instruction.
Enables the use of the fused multiply-add instruction. For the production release of Sun Studio 12, the recommended spelling of this switch is "-fma=fused". For pre-release versions, the same effect can be achieved via the spelling "-Wc,-fma=fused" (C) or "-Qoption cg -fma=fused" (C++, Fortran).
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 Fortran is 2. The default for C and C++ is 1.
Use STLport's Standard Library implementation instead of the default libCstd.

Collect profile data for feedback-directed optimization. If an option directory is named, the feedback will be stored there. When FDO is used, the training run gathers information regarding execution paths. As of the Sun Studio 11 version of the compiler suite, the training run gathers information about data values on SPARC systems, but not on x86 systems. Hardware performance counters are not used. FDO improves existing optimizations but does not introduce new classes of optimization.
Use data collected for profile feedback. If an option directory is named, look for the feedback data there.

This library provides faster versions of some common functions, such as malloc/free and bcopy.
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.
Assume data is naturally aligned.
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.
Use inline expansion for math library, libm.
Specify optimization level n:
Allow generation of prefetch instructions. -xprefetch=yes and -xprefetch are synonyms for -xprefetch=auto,explicit.
Selects options appropriate for the system where the compile is taking place, including architecture, chip, and cache sizes. (These can also be controlled separately, via -xarch, -xchip, and -xcache, respectively.)
Select the optimized math library.
Platform settings
One or more of the following settings may have been applied to the testbed. If so, the "Platform Notes" section of the report will say so; and you can read below to find out more about what these settings mean.
autoup=<n> (Unix /etc/system)
When the file system flush daemon fsflush runs, it writes to disk all modified file buffers that are more
than n seconds old.
bufhwm=<n> (Unix /etc/system)
Sets the upper limit of the file system buffer cache. The units for bufhwm are in kilobytes.
cpu_bringup_set=<n> (Unix /etc/system)
Specifies which processors are enabled at boot time. <n> represents a bitmap of the
processors to be brought online.
disablecomponent (System Management Services)
This command can be used prior to booting the system for a 1-cpu test. The tester uses disablecomponent to
add all other CPUs to the "blacklist", which is a list of components that cannot be used at boot time.
LD_LIBRARY_PATH=<directories> (linker)
LD_LIBRARY_PATH controls the search order for both the compile-time and run-time linkers. Usually, it can be
defaulted; but testers may sometimes choose to explicitly set it (as documented in the notes in the submission), in order to
ensure that the correct versions of libraries are picked up.
LD_PRELOAD=<shared object> (Unix environment variable)
Adds the named shared object to the runtime environment.
MADV=access_lwp and LD_PRELOAD=madv.so.1 (Unix environment variables)
When the madv.so.1 shared object is present in the LD_PRELOAD list, it is possible to provide advice to the system
about how memory is likely to be accessed. The advice present in MADV applies to all processes and their descendants. A
commonly used value is access_lwp, which means that when memory is allocated, the next process to touch it will be
the primary user. Examples of other possible values include sequential, for memory that is used only once and
then no longer needed and acces_many when many processes will be sharing data.
MPSSHEAP=<size>, MPSSSTACK=<size>, and
LD_PRELOAD=mpss.so.1 (Unix environment variables)
When these variables are set, the mpss.so.1 shared object will set the preferred page size for new processes, and their
descendants, to the requested sizes for the heap and stack.
PARALLEL=<n> (Unix environment variable)
If programs have been compiled with -xautopar, this environment variable can be set to the number of
processors that programs should use.
segmap_percent=<n> (Unix /etc/system)
This value controls the size of the segmap cache as a percent of total memory. Set this value to help keep the file system cache from consuming memory unnecessarily.
STACKSIZE=<n> (Unix environment variable)
Set the size of the stack (temporary storage area) for each slave thread of a multithreaded program.
submit=echo 'pbind -b...' > dobmk; sh dobmk (SPEC tools, Unix shell)
When running multiple copies of benchmarks, the SPEC config file feature submit is sometimes used to
cause individual jobs to be bound to specific processors. If so, the specific command may be found in the config file; here
is a brief guide to understanding that command:
svcadm disable webconsole (Unix, superuser commands)
Turns off the Sun Web Console, a browser-based interface that performs systems management.
If it is enabled, system administrators can manage systems, devices and services from remote systems.
ts_dispatch_extended=<n> (Unix /etc/system)
Controls which dispatch table is loaded upon boot. A value of 1 loads the large system table, a value of 0 loads the regular system table.
tune_t_fsflushr=<n> (Unix /etc/system)
Controls the number of seconds between runs of the file system flush daemon, fsflush.
ulimit -s <n> (Unix shell)
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).
