Peak Optimization Flags

C benchmarks

- -Qprof_gen
- PASS1_CFLAGS, PASS1_LDFLAGS
- Instrument program for profiling for the first phase of two-phase profile guided otimization. This instrumentation gathers information about a program's execution paths and data values but does not gather information from hardware performance counters. The profile instrumentation also gathers data for optimizations which are unique to profile-feedback optimization.
- -Qprof_use
- PASS2_CFLAGS, PASS2_LDFLAGS
- 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

447.dealII

- -Qprof_gen
- PASS1_CXXFLAGS, PASS1_LDFLAGS
- Instrument program for profiling for the first phase of two-phase profile guided otimization. This instrumentation gathers information about a program's execution paths and data values but does not gather information from hardware performance counters. The profile instrumentation also gathers data for optimizations which are unique to profile-feedback optimization.
- -Qprof_use
- PASS2_CXXFLAGS, PASS2_LDFLAGS
- 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
- -fast
- CXXOPTIMIZE
- The -fast option enhances execution speed across the entire program by including the following options that can improve run-time performance:
  
  -O3 (maximum speed and high-level optimizations)
  
  -Qipo (enables interprocedural optimizations across files)
  
  -QxP (generate code specialized for Intel Pentium 4 processor and compatible Intel processors with Streaming SIMD Extensions 3)
  
  -Qprec-div- (disable -Qprec-div) where -Qprec-div improves precision of FP divides (some speed impact)
  
  To override one of the options set by /fast, specify that option after the -fast option on the command line. The exception is the xP or QxP option which can't be overridden. The options set by /fast may change from release to release.
