4.SH NAME
5romcc \- compile C programs into binaries that don't use any RAM
6.SH SYNOPSIS
7.B romcc
8.BR [ OPTIONS ]
9.IR "<source>" ".c"
10.SH DESCRIPTION
11.B romcc
12is a C compiler which produces binaries which do not rely on RAM, but
13instead only use CPU registers.
14.br
15It is prominently used in the LinuxBIOS project to compile C code which
16needs to run before the (Linux)BIOS has initialized the RAM, but can be
17used for other purposes, too.
18.SH OPTIONS
19.B "\-o" <filename>
20Output file name.
21.PP
22.B "\-f<option>"
23Specify a generic compiler option.
24.PP
25.B "\-m<option>"
26Specify an architecture-dependent compiler option.
27.PP
28.B "\-\-"
29Specify that this is the last option.
