* Bring a couple of fixes for gcc optimizations.pfg2012-06-211-2/+6
| | | | | | | | | | | | | | The GCC4.3 branch contains some optimization fixes that were not considered regressions and therefore were never backported. We are bringing a couple of them that are under GPLv2 since they were made before the license switch upstream. While here, add the GCC revision numbers in the log. Discussed with: jkim MFC after: 1 week
* Revert r236962 - Experimental amdfam10/barcelona support.pfg2012-06-131-6/+2
| | | | | | | | The patches are unexpectedly causing gcc to fail while building ports/graphics/ImageMagick even when the cpu flags are not used. Reported by: Andreas Tobler
* Add experimental support for amdfam10/barcelona from the GCC 4.3 branch.pfg2012-06-121-2/+6
| | | | | | | | | | | | | | | | | | | Initial support for the AMD barcelona chipsets has been available in the gcc43 branch under GPLv2 but was not included when the Core 2 support was brought to the system gcc. AMD and some linux distributions (OpenSUSE) did a backport of the amdfam10 support and made them available. Unfortunately this is still experimental and while it can improve performance, enabling the CPUTYPE may break some C++ ports (like clang). Special care was taken to make sure that the patches predate the GPLv3 switch upstream. Tested by: Vladimir Kushnir Reviewed by: mm Approved by: jhb (mentor) MFC after: 2 weeks

non-i386, non-unix, and generatable files have been trimmed, but can easily be added in later if needed. gcc-2.7.2.1 will follow shortly, it's a very small delta to this and it's handy to have both available for reference for such little cost. The freebsd-specific changes will then be committed, and once the dust has settled, the bmakefiles will be committed to use this code.
