linux-toradex.git/include/linux/compiler-gcc.h, branch v2.6.20.21 Linux kernel for Apalis and Colibri modules [PATCH] Work around ppc64 compiler bug 2006-01-10T16:32:35+00:00 Anton Blanchard anton@samba.org 2006-01-10T07:21:20+00:00 c8d52465f95c4187871f8e65666c07806ca06d41 In the process of optimising our per cpu data code, I found a ppc64 compiler bug that has been around forever. Basically the current RELOC_HIDE can end up trashing r30. Details of the bug can be found at http://gcc.gnu.org/bugzilla/show_bug.cgi?id=25572 This bug is present in all compilers before 4.1. It is masked by the fact that our current per cpu data code is inefficient and causes other loads that end up marking r30 as used. A workaround identified by Alan Modra is to use the =r asm constraint instead of =g.

This bug is present in all compilers before 4.1. It is masked by the
fact that our current per cpu data code is inefficient and causes
other loads that end up marking r30 as used.

A workaround identified by Alan Modra is to use the =r asm constraint
instead of =g.

I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip! 
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
