The assembly language output
This is certainly nothing which will change in 2.96-RH, as it is in important bugfixes mode only. If you get the same behaviour with gcc 3.3, file an enhancement request at http://gcc.gnu.org/gnats.html. Well, I would love to test it on gcc 3.3 or something similar, but those things aren't available in a standard non-beta distribution yet. In fact AFAIK, gcc 3.3 isn't even released yet. It seems odd to me that I should have to download and hand-build the unstable CVS tree for a compiler simply so I can report a case of inadequate optimization. Of course, the differences between 2.96 and 3.2 in the optimization department are rather marked. So if you insist I try it in a 3.2 version when RH 8.0 comes out, I'll do so. Well, at least 3.1 is available for 7.3 as secondary compiler (there is a special RHN channel for it), so you can check that. The point in filing PR in gcc GNATS is that your enhancement request will get there greater audience. |
