There are currently only a few compiler related flags available to be used for a specific method only (and not by default for all compiled methods):

Defined in compilerDirectives.hpp:
  #define compilerdirectives_common_flags(cflags) \
    cflags(Enable, bool, false, X) \
    cflags(Exclude, bool, false, X) \
    cflags(BreakAtExecute, bool, false, X) \
    cflags(BreakAtCompile, bool, false, X) \
    cflags(Log, bool, LogCompilation, X) \
    cflags(PrintAssembly, bool, PrintAssembly, PrintAssembly) \
    cflags(PrintInlining, bool, PrintInlining, PrintInlining) \
    cflags(PrintNMethods, bool, PrintNMethods, PrintNMethods) \
    cflags(BackgroundCompilation, bool, BackgroundCompilation, BackgroundCompilation) \
    cflags(ReplayInline, bool, false, ReplayInline) \
    cflags(DumpReplay, bool, false, DumpReplay) \
    cflags(DumpInline, bool, false, DumpInline) \
    cflags(CompilerDirectivesIgnoreCompileCommands, bool, CompilerDirectivesIgnoreCompileCommands, X) \
    cflags(DisableIntrinsic, ccstrlist, DisableIntrinsic, DisableIntrinsic)

#ifdef COMPILER1
  #define compilerdirectives_c1_flags(cflags)
#else
  #define compilerdirectives_c1_flags(cflags)
#endif

#ifdef COMPILER2
  #define compilerdirectives_c2_flags(cflags) \
    cflags(BlockLayoutByFrequency, bool, BlockLayoutByFrequency, BlockLayoutByFrequency) \
    cflags(PrintOptoAssembly, bool, PrintOptoAssembly, PrintOptoAssembly) \
    cflags(PrintIntrinsics, bool, PrintIntrinsics, PrintIntrinsics) \
NOT_PRODUCT(cflags(TraceOptoPipelining, bool, TraceOptoPipelining, TraceOptoPipelining)) \
NOT_PRODUCT(cflags(TraceOptoOutput, bool, TraceOptoOutput, TraceOptoOutput)) \
NOT_PRODUCT(cflags(PrintIdeal, bool, PrintIdeal, PrintIdeal)) \
NOT_PRODUCT(cflags(IGVPrintLevel, intx, PrintIdealGraphLevel, IGVPrintLevel)) \
    cflags(TraceSpilling, bool, TraceSpilling, TraceSpilling) \
    cflags(Vectorize, bool, false, Vectorize) \
    cflags(VectorizeDebug, uintx, 0, VectorizeDebug) \
    cflags(CloneMapDebug, bool, false, CloneMapDebug) \
    cflags(MaxNodeLimit, intx, MaxNodeLimit, MaxNodeLimit)
#else
  #define compilerdirectives_c2_flags(cflags)
#endif

We should add more flags to these lists. Especially for debug builds, it would be beneficial to allow any compiler related flag to be used on a per method level to improve debugging.
