llvm-gcc

GCC frontend for the LLVM compiler infrastructure

TLDR

Compile C program

$ llvm-gcc -o [program] [source.c]

Compile with optimization

$ llvm-gcc -O2 -o [program] [source.c]

Generate LLVM bitcode

$ llvm-gcc -emit-llvm -c [source.c]

SYNOPSIS

llvm-gcc [options] sourcefiles_...

DESCRIPTION

llvm-gcc is a GCC frontend for the LLVM compiler infrastructure. Provides GCC-compatible interface that generates LLVM intermediate representation. Deprecated in favor of clang.

PARAMETERS

-o file

Output file name.

-O level

Optimization level (0-3).

-emit-llvm

Generate LLVM bitcode.

-c

Compile only, no linking.

-S

Generate assembly output.

-g

Include debug information.

CAVEATS

This tool is deprecated. Use clang instead for LLVM-based compilation.
