Low Level Virtual Machine
NAME
llc
SYNOPSIS
llc [options] < filename>
DESCRIPTION
The llc command compiles LLVM bytecode into assembly language for a specified
architecture. The assembly language output can then be passed through a native
assembler and linker to generate native code.
OPTIONS
- -disable-fp-elim
Disable frame pointer elimination optimization
- -disable-local-ra
Use Simple RA instead of Local RegAlloc
- -disable-pattern-isel
Use the 'simple' X86 instruction selector
- -disable-peephole
Disable peephole optimization pass
- -disable-preopt
Disable optimizations prior to instruction selection
- -disable-sched
Disable local scheduling pass
- -disable-strip
Do not strip the LLVM bytecode included in executable
- -enable-maps
Emit LLVM-to-MachineCode mapping info to assembly
- -f
Overwrite output files
- -load=<plugin.so>
Load the specified plugin
- -m<arch>
Specify the architecture for which to generate assembly. Valid
architectures are:
x86
-

sparc
- SPARC V9
- -o <filename>
Output filename
- -print-machineinstrs
Print generated machine code
- -help
Print a summary of command line options.
- -stats
Print statistics.
- -time-passes
Record the amount of time needed for each pass and print it to standard
error.
