命令

bloaty.exe --list-sources rmembers the .o files in a .a file compileunits source file for the .o file (translation unit). requires debug info. inputfiles the filename specified on the Bloaty command-line inlines source line/file where inlined code came from. requires debug info. sections object file section segments load commands in the binary symbols symbols from symbol table (configure demangling with --demangle) rawsymbols unmangled symbols fullsymbols full demangled symbols shortsymbols short demangled symbols

bloaty.exe --help USAGE: bloaty [OPTION]... FILE... [-- BASE_FILE...] Options: --csv Output in CSV format instead of human-readable. --tsv Output in TSV format instead of human-readable. -c FILE Load configuration from <file>. -d SOURCE,SOURCE Comma-separated list of sources to scan. --debug-file=FILE Use this file for debug symbols and/or symbol table. -C MODE How to demangle symbols. Possible values are: --demangle=MODE --demangle=none no demangling, print raw symbols --demangle=short demangle, but omit arg/return types --demangle=full print full demangled type The default is --demangle=short. --disassemble=FUNCTION Disassemble this function (EXPERIMENTAL) --domain=DOMAIN Which domains to show. Possible values are: --domain=vm --domain=file --domain=both (the default) -n NUM How many rows to show per level before collapsing other keys into '[Other]'. Set to '0' for unlimited. Defaults to 20. -s SORTBY Whether to sort by VM or File size. Possible values are: -s vm -s file -s both (the default: sorts by max(vm, file)). -w Wide output; don't truncate long labels. --help Display this message and exit. --list-sources Show a list of available sources and exit. --source-filter=PATTERN Only show keys with names matching this pattern. Options for debugging Bloaty: --debug-vmaddr=ADDR --debug-fileoff=OFF Print extended debugging information for the given VM address and/or file offset. -v Verbose output. Dumps warnings encountered during processing and full VM/file maps at the end. Add more v's (-vv, -vvv) for even more.
