1 .TH ROMCC 1 "September 19, 2006"
3 romcc \- compile C programs into binaries that don't use any RAM
10 is a C compiler which produces binaries which do not rely on RAM, but
11 instead only use CPU registers.
13 It is prominently used in the coreboot project to compile C code which
14 needs to run before the firmware has initialized the RAM, but can be
15 used for other purposes, too.
22 Specify a generic compiler option.
25 Specify an architecture-dependent compiler option.
28 Specify that this is the last option.
