Maksim Panchenko 0bde796e50 [BOLT] Organize options in categories for pretty printing (near NFC). ... Summary: Each BOLT-specific option now belongs to BoltCategory or BoltOptCategory. Use alphabetical order for options in source code (does not affect output). The result is a cleaner output of "llvm-bolt -help" which does not include any unrelated llvm options and is close to the following: ..... BOLT generic options: -data=<string> - <data file> -dyno-stats - print execution info based on profile -hot-text - hot text symbols support (relocation mode) -o=<string> - <output file> -relocs - relocation mode - use relocations to move functions in the binary -update-debug-sections - update DWARF debug sections of the executable -use-gnu-stack - use GNU_STACK program header for new segment (workaround for issues with strip/objcopy) -use-old-text - re-use space in old .text if possible (relocation mode) -v=<uint> - set verbosity level for diagnostic output BOLT optimization options: -align-blocks - try to align BBs inserting nops -align-functions=<uint> - align functions at a given value (relocation mode) -align-functions-max-bytes=<uint> - maximum number of bytes to use to align functions -boost-macroops - try to boost macro-op fusions by avoiding the cache-line boundary -eliminate-unreachable - eliminate unreachable code -frame-opt - optimize stack frame accesses ......
