Implement getcontext for x86 Greetings, Attached patch implements getcontext for x86. Motivation is the same as: http://lists.nongnu.org/archive/html/libunwind-devel/2008-06/msg00009.html This also fixes check-name-space on x86. Tested on Linux/86 with no new failures. Thanks, -- Paul Pluzhnikov 2009-12-23 03:58:17 +01:00			`#define LINUX_UC_FPREGS_MEM_OFF 0xec`
