Good idea ! BTW, without http://gcc.gnu.org/ml/gcc-patches/2003-05/msg00575.html the tree-ssa branch won't build on Alpha. Oh, and you need about a dozen no-warn entries added to gcc/gcc/Makefile.in :-( For test results (c,f77,f95 only), see: http://gcc.gnu.org/ml/gcc-testresults/2003-05/msg00630.html Cheers, -- Toon Moene - mailto:toon@moene.indiv.nluug.nl - phoneto: +31 346 214290 Saturnushof 14, 3738 XG Maartensdijk, The Netherlands Maintainer, GNU Fortran 77: http://gcc.gnu.org/onlinedocs/g77_news.html GNU Fortran 95: http://gcc-g95.sourceforge.net/ (under construction) ^ permalink raw reply [flat|nested] 11+ messages in thread

GIMPLE tends to emit conditionals that trigger warnings like 'used before definition'. I believe that Jason was working on a change that would fix this. In any case, for now they are OK to list as no-warn, but we will need to remove those settings before merging. Could you add these entries near the existing FIXME note when you patch Makefile.in?

Are these warnings valid, or is it the well-known problem that gcc can't deal with pointer* p; bool flag = false; if (expensive()) { p = init_p(); flag = true; } do_something_else(); if (flag) { use(p); } ? That is, gcc's uninitialized warning misses correlations between variables, so this kind of thing gives a false warning at use(p). ^ permalink raw reply [flat|nested] 11+ messages in thread

The more common false positive is due to the way the gimplifier restructures complex conditional expressions like 'if (v && (x = foo()))'. This sometimes leaves code similar to what you quote in your message. To properly fix this we need to restructure the code emitted by the gimplifier and, probably, move some of the other warnings into the tree-ssa passes.

So, you couldn't have possibly seen it yet :) With any luck, the merge should be committed tomorrow or Wed. I still have some testsuite failures to go through.
