Author: andersen
Date: 2005-03-02 05:30:29 -0700 (Wed, 02 Mar 2005)
New Revision: 9959
Log:
Fix things the other way round. Instead of restoring the mips
embedded pic support into binutils, instead fixup gcc to not emit
any embedded pic relocations.

+Subject: [trunk + 3.4-branch RFA] don't use empic relocs for mips-linuxeh
+
+This patch changes mips-linux to avoid using embedded-pic relocs for
+its eh data. (Support for generating these for new code is removed in
+current binutils srcs.)
+
+Relating to this, previously, mips-linux and mips64-linux would use
+different representations for their EH data (even for mips64-linux o32
+abi), due to the mips64-linux n32/64 BFDs not supporting the
+embedded-pic relocs. This was a bug.
+
+For more explanation, see the thread of the URL quoted in the comment
+in linux.h.
+
+
+Tested the same w/ sources of about a week ago for c/c++ for
+mips-linux (native) before/after. Also verified .o compatibility
+before/after just to be sure.
+
+I'd like this approved for the branch as well, so 3.4.1 will work
+nicely w/ the next major binutils release.
+
+
+thanks,
+
+chris
