llc - LLVM static compiler
SYNOPSIS
:program:`llc` [options] [filename]
DESCRIPTION
The :program:`llc` command compiles LLVM source inputs into assembly language for a specified architecture. The assembly language output can then be passed through a native assembler and linker to generate a native executable.
The choice of architecture for the output assembly code is automatically determined from the input file, unless the :option:`-march` option is used to override the default.
OPTIONS
If filename
is "-
" or omitted, :program:`llc` reads from standard input.
Otherwise, it will from filename
. Inputs can be in either the LLVM assembly
language format (.ll
) or the LLVM bitcode format (.bc
).
If the :option:`-o` option is omitted, then :program:`llc` will send its output
to standard output if the input is from standard input. If the :option:`-o`
option specifies "-
", then the output will also be sent to standard output.
If no :option:`-o` option is specified and an input file other than "-
" is
specified, then :program:`llc` creates the output filename by taking the input
filename, removing any existing .bc
extension, and adding a .s
suffix.
Other :program:`llc` options are described below.

EXIT STATUS
If :program:`llc` succeeds, it will exit with 0. Otherwise, if an error occurs, it will exit with a non-zero value.
