Phoronix: GCC 4.7.3 Released With 118+ Bug-Fixes

For those using the proven and tested GCC 4.7 compiler series rather than the brand new GCC 4.8, there is now GCC 4.7.3 with over one hundred bug-fixes over the previous release...

Is there some human-readable chhangelog wrt to 4.7.2 ?

I could never understand that page at:

http://gcc.gnu.org/ml/gcc/2013-04/msg00121.html

Where are those 118 bugs in there ?

I probably should have gone for that. I just upgraded my toolchain last night and went with gcc 4.8.0 (was previously using gcc 4.5.2). Everything seems fine so far, but you never know until you go to compile something old, or finicky, or slightly incorrect.

I like when projects keep maintaining the previous versions for a while.

The most awful compiler switch was from gcc 2.95 (EGCS ) to gcc 3.x when they made major changes (both source and binary incompatible in some cases). Once refined a bit, those changes seem to have been a bit future proof, because there hasn't been such a hardship since.

Ditto, nice how they do it much in the same fashion as the kernel devs where you can roll back if you do have some oddball issues which generally crop up when compiling some real old or esoteric code. Imagine trying to compile an ancient Linux kernel like the 1.x series with the newest GCC just for fun and giggles =)

@ryszardzonk:

Thanks. That page is so looong that I never even tried to fight my way through the end. Since beginning it is all about 4.7 in general, it never crossed my mind to try to find anything specific at the bottom.


I managed to rework ebuild from version 4.7.2 on Gentoo to 4.7.3 and filter and repatch patches for it to work for 4.7.3.

It is being compiled right now. If it succeeds, I'l post it on bugs.gentoo.org...

[Brane215]

Hmm. Just as I thought, not many of those bugfixes were about -flto linking. gcc-4.7.3 has about the same success rate with -flto as did 4.7.2.

Not worth recompiling whole system with it, but welcome refresh for new packages IMO...
