From 8d0b9dc9be3919e9979eac59fd12e8f82b098325 Mon Sep 17 00:00:00 2001 From: Al Viro Date: Thu, 5 May 2005 16:15:23 -0700 Subject: [PATCH] uml: start cross-build support : mk_user_constants Beginning of cross-build fixes. Instead of expecting that mk_user_constants (compiled and executed on the build box) will see the sizeof, etc. for target box, we do what every architecture already does for asm-offsets. Namely, have user-offsets.c compiled *for* *target* into user-offsets.s and sed it into the header with relevant constants. We don't need to reinvent any wheels - all tools are already there. This patch deals with mk_user_constants. It doesn't assume any relationship between target and build environment anymore - we pick all defines we need from user-offsets.h. Later patches will deal with the rest of mk_... helpers in the same way.
