From: H. Peter Anvin Date: Tue, 28 Oct 2008 05:19:59 +0000 (-0700) Subject: output: add common file outlib.c for common functions; realsize() X-Git-Tag: nasm-2.11.05~1141^2 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=03c4f90afa42cc8a7ed842ff0fc9d3c18a06dd2d;p=platform%2Fupstream%2Fnasm.git output: add common file outlib.c for common functions; realsize() Add a common file, outlib.c, for output formats. Add the function realsize() instead of open-coded variants in almost every backend. Signed-off-by: H.
