Move some complex simplifications to match.pd

Hello, just trying to shrink fold-const.c a bit more. The tests "if (TREE_CODE (TREE_TYPE (arg0)) != COMPLEX_TYPE)" seem useless, I did one bootstrap+testsuite with asserts there to make sure, so I am dropping them. The CONJ_EXPR simplifications don't seem very useful, as far as I can tell CO

Move some comparison simplifications to match.pd

Hello, just trying to shrink fold-const.c a bit more. initializer_zerop is close to what I was looking for with zerop, but I wasn't sure if it would be safe (it accepts some CONSTRUCTOR and STRING_CST). At some point I tried using sign_bit_p, but using the return of that function in the simpl

[PATCH, rs6000] Improve swap optimization to modify general xxpermdi patterns

Hi, The VSX swap optimization currently misses opportunities to optimize loops when expressions corresponding to xxpermdi instructions are present (other than xxswapd instructions associated with loads and stores). These occur commonly when interleaving vector double or vector unsigned long opera

I've committed the patch with the attached ChangeLog entry after testing on sh-elf and i686-pc-linux-gnu. I'd like to backport it to the 5-branch after a week or so. Rich, thanks for the patch. Regards, kaz -- 2015-08-30 Rich Felker * config.gcc (supported_defaults): Handle sh[

Go patch committed: check for invalid UTF-8 in line comments
