From 003086497f07f7f1e67c0c295e261740f822b377 Mon Sep 17 00:00:00 2001 From: Kyle McMartin Date: Mon, 23 Mar 2009 15:25:49 -0400 Subject: Build with -fno-dwarf2-cfi-asm With a sufficiently new compiler and binutils, code which wasn't previously generating .eh_frame sections has begun to. Certain architectures (powerpc, in this case) may generate unexpected relocation formats in response to this, preventing modules from loading. While the new relocation types should probably be handled, revert to the previous behaviour with regards to generation of .eh_frame sections. (This was reported against Fedora, which appears to be the only distro doing any building against gcc-4.4 at present: RH bz#486545.)
