[PATCH] [pass_if_conversion] Extend is_cond_scalar_reduction to handle bit_and/bit_xor/bit_ior.

This will enable transformation like - # sum1_50 = PHI - # sum2_52 = PHI + # sum1_50 = PHI <_87(13), 0(4)> + # sum2_52 = PHI <_89(13), 0(4)> # ivtmp_62 = PHI i.2_7 = (long unsigned int) i_49; _8 = i.2_7 * 8; ... vec1_i_38 = vec1_29 >> _10; vec2_i_39 = vec2_31 >> _10; _11 =

[PATCH] fix up compute_objsize (including PR 103143)

The pointer-query code that implements compute_objsize() that's in turn used by most middle end access warnings now has a few warts in it and (at least) one bug. With the exception of the bug the warts aren't behind any user-visible bugs that I know of but they do cause problems in new code I've

[PATCH] PR tree-optimization/102232 Adding a missing pattern to match.pd

Hi GCC community, This patch will add the missed pattern described in bug 102232 [1] to the match.pd. The testcase will test whether the multiplication and division has been removed from the code or not. The correctness proof for this pattern is here [2] in case anyone is curious. PR tree-opti
