[PATCH][2.4.30-rc1] updated gcc-4.0 patches
From: Mikael Pettersson
Date: Sat Mar 19 2005 - 11:28:57 EST
Here is a new set of patches to allow gcc-4.0 (20050312)
to compile the 2.4.30-rc1 kernel. Changes since the previous
version of the patch set are:
- Replaced -ffreestanding with -fno-builtin-sprintf.
freestanding was used to prevent gcc from transforming some
sprintf() calls to calls to strcpy(), but no-builtin-sprintf
solves that problem w/o the other problems of freestanding.
(Thanks to Mikael Starvik for the -fno-builtin-sprintf hint.)
- Removed the abs()-related workarounds I had before because
of -ffreestanding.
- Fixed typo in <linux/compiler.h>'s #ifdef around the
__attribute_const__ definition. (Found by Mikael Starvik.)
Tested on i386, ppc32, and x86-64. The only known problem is
that the X server segfaults during PCI probing on x86-64. I'm
currently debugging that.
In addition to this core patch there is a big pile of compile
fixes to drivers etc that haven't been runtime tested. That patch
is too large for sending to LKML, so it's downloadable as
<http://www.csd.uu.se/~mikpe/linux/patches/2.4/patch-more-gcc4-fixes-v1-2.4.30-rc1>.
