.SH NAME
romcc \- compile C programs into binaries that don't use any RAM
.SH SYNOPSIS
.B romcc
[OPTIONS]
<source>.c
.SH DESCRIPTION
.B romcc
is a C compiler which produces binaries which do not rely on RAM, but
instead only use CPU registers.
.PP
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.
