OVERVIEW: llvm machine code playground
USAGE: llvm-mc [options] <input file>
OPTIONS:
Color Options:
--color - Use colors in output (default=autodetect)
Generic Options:
--help - Display available options (--help-hidden for more)
--help-list - Display list of available options (--help-list-hidden for more)
--version - Display the version of this program
MC Options:
-I <directory> - Directory of include files
-M <string> - InstPrinter options
--arch=<string> - Target arch to assemble for, see -version for available targets
Action to perform:
--as-lex - Lex tokens from a .s file
--assemble - Assemble a .s file (default)
--disassemble - Disassemble strings of hex bytes
--mdis - Marked up disassembly of strings of hex bytes
--cdis - Colored disassembly of strings of hex bytes
--compress-debug-sections=<value> - Choose DWARF debug sections compression:
=none - No compression
=zlib - Use zlib
=zstd - Use zstd
--defsym=<string> - Defines a symbol to be an integer constant
--fdebug-compilation-dir=<string> - Specifies the debug info's compilation dir
--fdebug-prefix-map=<= separated key-value pairs> - Map file source paths in debug info
--filetype=<value> - Choose an output file type:
=asm - Emit an assembly ('.s') file
=null - Don't emit anything (for timing purposes)
=obj - Emit a native object ('.o') file
-g - Generate dwarf debugging info for assembly source files
--hex - Take raw hexadecimal bytes as input for disassembly. Whitespace is ignored
--large-code-model - Create cfi directives that assume the code might be more than 2gb away
--main-file-name=<string> - Specifies the name we should consider the input file
--masm-hexfloats - Enable MASM-style hex float initializers (3F800000r)
--masm-integers - Enable binary and hex masm integers (0b110 and 0ABCh)
--mattr=<a1,+a2,-a3,...> - Target specific attributes (-mattr=help for details)
--mcpu=<cpu-name> - Target a specific cpu type (-mcpu=help for details)
--motorola-integers - Enable binary and hex Motorola integers (%110 and $ABC)
-n - Don't assume assembly file starts in the text section
--no-exec-stack - File doesn't need an exec stack
-o <filename> - Output filename
--output-asm-variant=<uint> - Syntax variant to use for output printing
--position-independent - Position independent
--preserve-comments - Preserve Comments in outputted assembly
--print-imm-hex - Prefer hex format for immediate values
--runs=<uint> - Number of runs for benchmarking
--show-encoding - Show instruction encodings
--show-inst - Show internal instruction representation
--show-inst-operands - Show instructions operands as parsed
--split-dwarf-file=<filename> - DWO output filename
--triple=<string> - Target triple to assemble for, see -version for available targets
--validate-cfi - Validate the CFI directives
