.TH ROMCC 1 "September 19, 2006"
.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.
.SH OPTIONS
.TP
.B "\-o" <filename>
Output file name.
.TP
.B "\-f<option>"
Specify a generic compiler option.
.TP
.B "\-m<option>"
Specify an architecture-dependent compiler option.
.TP
.B "\-\-"
Specify that this is the last option.
