Subject: [PATCH] Use .incbin for piggy.o
Date: Thu, 21 Aug 2003 00:44:42 -0400 [thread overview]
Message-ID: <3F444E3A.2010507@quark.didntduck.org> (raw)
[-- Attachment #1: Type: text/plain, Size: 210 bytes --]
Simplify creation of piggy.o (i386 arch) using .incbin instead of an ld
script.
Several other arches use the same method, and should be changed
accordingly by the respective maintainers.
