-INTEL C++ COMPILER 7.1 FLAG DESCRIPTIONS-
------------------------------------------

-G{5|6|7} Optimize code specifically for a targeted processor. Includes
one or more of the following characters:
5: Pentium processors with or without MMX technology
6: Pentium Pro, Pentium II, and Pentium III processors
7: Pentium 4 processor

-GR[-] Enables [disables (DEFAULT)] C++ Runtime Type Information (RTTI).

-GX[-] Enables [disables (DEFAULT)] C++ exception handling.

-O{1|2|3} Optimization-level options:
1: optimize for speed, but disable some optimizations that
increase code size for a small speed benefit. Includes
inline expansion for intrinsic functions, global
optimizations, string pooling optimizations.
2: optimizes for speed (DEFAULT). The -O2 option includes O1
optimizations and in addition enables inlining of
intrinsics and more speed optimizations.
3: builds on -01 and -02 optimizations by enabling high-level
optimization. This level does not guarantee higher performance
unless loop and memory access transformation take place. In
conjunction with -QaxK/-QxK and QaxW/QxW, this switch causes
the compiler to perform more aggressive data dependency
analysis than for -O2. This may result in longer compilation
times.

-Oa[-] Assume [do not assume] no aliasing in program.

-Oi[-] Enables (DEFAULT) [disables] inline expansion of standard
library functions.

-Qax{i|M|K|W} Generate code specialized for processor extensions
specified by <codes> while also generating generic IA-32 code.
Includes one or more of the following characters:
i: Pentium Pro and Pentium II processor instructions
M: MMX(TM) instructions
K: SSE extensions
W: SSE2 extensions

-Qx{i|M|K|W} Generate specialized code to run exclusively on processors
supporting the extensions indicated by <codes> as described above.

NOTE: -Qx{character(s)} and -Qax{character(s)} all ensure more
consistent floating point arithmetic with some speed impact by
rounding fp results at assignments & preserving user visible impact of casts which lose precision. This behaviour can be achieved by using the
-Qfp_port option as well.

-Qip Enable single-file IP optimizations (within files, same as -Ob2).

-Qipo Enable multi-file IP optimizations (between files).
- inline function expansion
- interprocedural constant propogation
- dead code elimination
- propagation of function characteristics
- passing arguments in registers
- loop-invariant code motion

-Qwp_ipo Additionally to -Qipo, makes the whole program assumption that
all variables and functions seen in compiled sources are
referenced only within those sources; the user must guarantee
that this assumption is safe.

-Qprof_gen Instrument program for profiling for the first phase of
two-phase profile guided optimization.

-Qprof_use Instructs the compiler to produce a profile-optimized
executable and merges available dynamic information (.dyn)
files into a pgopti.dpi file. If you perform multiple
executions of the instrumented program, -Qprof_use merges
the dynamic information files again and overwrites the
previous pgopti.dpi file. Without any other options,
the current directory is searched for .dyn files.

-Qrcd The Intel compiler uses the -Qrcd option to improve the
performance of code that requires floating-point-to-integer
conversions.

The system default floating point rounding mode is
round-to-nearest. This means that values are rounded during
floating point calculations. However, the C language requires
floating point values to be truncated when a conversion to an
integer is involved. To do this, the compiler must change the
rounding mode to truncation before each floating
point-to-integer conversion and change it back afterwards.

The -Qrcd option disables the change to truncation of the
rounding mode for all floating point calculations, including
floating point-to-integer conversions. Turning on this option
can improve performance, but floating point conversions to
integer may not conform to C semantics.

-Qunroll[n] Specifies the maximum number of times to unroll a loop. Omit n
to let the compiler decide whether to perform unrolling or not.
Use n = 0 to disable unroller.

-Zp(1|2|4|8|16) Use the -Zp{n} option to determine the alignment constraint for structure declarations, on n-byte boundary
(n = 1, 2, 4, 8, 16). Generally, smaller constraints result in smaller data sections while larger constraints
support faster execution.

For example, to specify 2 bytes as the alignment constraint for all structures and unions in the file
prog1.c, use the following command:

<compiler> -Zp2 prog1.c

The default is -Zp16.

-Oa[-] Assume [do not assume] no aliasing in program.

-Ob{0|1|2} Controls the compiler's inline expansion.
0: disable inlining.
1: disables inlining unless /Qip or /Ob2 are specified.
2: enables inlining of any function. However, the compiler
decides which functions are inlined. This option enables
interprocedural optimizations and ahs the same effect as
specifying the /Qip option.

-Qauto Causes all variables to be allocated on the stack, rather than
in local static storage.

-Qx{i|M|K|W} Generate specialized code to run exclusively on processors
supporting the extensions indicated by <codes> as
described above.

-Qip Enable single-file IP optimizations (within files, same as /Ob2).

-Qprefetch[-] Enable [disable (DEFAULT)] prefetch insertion. The default
with -O3 is -Qprefetch.

-Qprof_gen Instrument program for profiling for the first phase of
two-phase profile guided otimization.

-Qrcd The Intel compiler uses the -Qrcd option to improve the
performance of code that requires floating-point-to-integer
conversions.

-Qscalar_rep[-] Enables (DEFAULT) [disables] scalar replacement performed
during loop transformations.

-Qunroll[n] Specifies the maximum number of times to unroll a loop. Omit n
to let the compiler decide whether to perform unrolling or not.
Use n = 0 to disable unroller.
