Peak Optimization Flags

C benchmarks

400.perlbench

• • -Qprof_gen
  • 
  • PASS1_CFLAGS, PASS1_LDFLAGS

  • Instruments a program for profiling.

    This option instruments a program for profiling to get the execution count of each basic block. It also creates a new static profile information file (.spi).

    It is used in phase 1 of the Profile Guided Optimizer (PGO) to instruct the compiler to produce code in your object files in preparation for instrumented execution.

    • Gathers information regarding execution paths.
    • Gathers information regarding data values.
    • Does not use hardware performance counters.
• • -Qprof_use
  • 
  • PASS2_CFLAGS, PASS2_LDFLAGS

  • Enables the use of profiling information during optimization.

    This option enables the use of profiling information (including function splitting and function grouping) during optimization. It enables option -Qfnsplit.

    This option instructs the compiler to produce a profile-optimized executable and it merges available profiling output files into a pgopti.dpi file.

    Note that there is no way to turn off'function grouping if you enable it using this option.

    • Uses information regarding execution paths.
    • Uses information regarding data values.
    • Does not use hardware performance counters.
    • Uses techniques (like function grouping) which are not available without PGO.
  • Includes:
    • -Qfnsplit
• • -fast
  • 
  • OPTIMIZE

  • Maximize speed across the entire program.
