From 355bd3d4ea761a66880088ac2d0c5c95866df4a6 Mon Sep 17 00:00:00 2001 From: Andi Kleen Date: Fri, 21 Apr 2006 09:43:22 +0200 Subject: [PATCH] [PATCH] x86_64: Pass -32 to the assembler when compiling the 32bit vsyscall pages This quietens warnings and actually fixes a bug. The unwind tables would come out wrong without -32, causing pthread cancellation during them to crash in the gcc runtime. The problem seems to only happen with newer binutils (it doesn't happen with 2.16.91.0.2 but happens wit 2.16.91.0.5) Thanks to Brian Baker @ HP for test case and initial analysis.
