410.bwaves

    • -Qprof_gen
    • [user]
    • PASS1_FFLAGS, 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
    • [user]
    • PASS2_FFLAGS, 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
    • [user]
    • OPTIMIZE
    • 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.

    • Includes:
    • /F1000000000
    • [user]
    • EXTRA_LDFLAGS
    • set the stack reserve amount specified to the linker

    • -link /FORCE:MULTIPLE
    • [user]
    • LDOUT
    • Enable SmartHeap library usage by forcing the linker to ignore multiple definitions
