Author: dcoakley Date: 2011-12-14 16:11:19 -0500 (Wed, 14 Dec 2011) New Revision: 3851
Modified: trunk/osprey/linux/make/gcommondefs Log: Use default target architecture for build of x86 compiler and libraries. Previously the build used the "-march=anyx86" option to target the most generic cpu possible. However, newer Linux distributions such as Fedora 16 64-bit are built to assume SSE2 support (e.g. by using SSE2 instructions in inline assembly in the system header files) even for 32-bit code as all 64-bit capable x86 processors also support SSE2. Instead of trying to target a specific cpu, the build now targets the auto-detected cpu of the host system.
