Phoronix: GCC 4.3.1 Released With Bug Fixes

It's been just under three months since GCC 4.3.0 was released with support for Intel's SSE4.1/SSE4.2 instruction sets and experiment C++0x support, and now there is GCC 4.3.1. The GCC 4.3.1 release fixes a number of regressions and other bugs, which are all laid out within the GCC BugZilla...

There are guides for compiling GCC at http://linuxhelp.150m.com and http://linux.50webs.org/ under the title:

"Free Compilers and Cross-Compilers for Linux and Windows."

GCC version 4.2.3 is covered in:

GCC version 4.3.0 is covered in:

GCC version 4.3.1 still has some of the same bugs as 4.3.0,... guess I should have written a few bug reports.

These changes for the new compiles don't do a thing if the binaries are compiled for i386 though, yeah?

if you recompile glibc with new gcc with -march=core2 then your i386 binary will use functions compiled against new core2 architecture, but its not ideal, better is to recompile whole portage :)

I'm not going to be recompiling anything, just wanting to see if it affects the default installation any.

I suppose amd64 builds can take a better advantage of the new features though, since these processors are more recent than i386.
