NAME¶
romcc - compile C programs into binaries that don't use any RAM
SYNOPSIS¶
romcc [OPTIONS] <source>.c
DESCRIPTION¶
romcc is a C compiler which produces binaries which do not rely on RAM, but instead only use CPU registers.
It is prominently used in the coreboot project to compile C code which needs to run before the firmware has initialized the RAM, but can be used for other purposes, too.

- Output file name.
- -f<option>
- Specify a generic compiler option.
- -m<option>
