CVS commit: src/lib/libc/arch/i386/gen
Module Name:src
Committed By: drochner
Date: Fri Aug 31 20:57:24 UTC 2012
Modified Files:
src/lib/libc/arch/i386/gen: _lwp.c
Log Message:
Align the stack to a 16-byte boundary on LWP creation.
This is more than required by the ABI, but it makes programs using SSE
in a thread work without extra compiler flags or performance hit.
