2017-09-21Add missing int_cst_rangeN checks to tree-vrp.cRichard Sandiford2-2/+11
The BIT_AND_EXPR handling in extract_range_from_binary_expr_1 was using value_range_constant_singleton without first checking whether the range was a constant. The earlier handling was correctly guarded: /* If either input range contains only non-negative values we can truncate the result range maximum to the respective maximum of the input range. */ if (int_cst_range0 && tree_int_cst_sgn (vr0.min) >= 0) wmax = wi::min (wmax, vr0.max, TYPE_SIGN (expr_type)); if (int_cst_range1 && tree_int_cst_sgn (vr1.min) >= 0) wmax = wi::min (wmax, vr1.max, TYPE_SIGN (expr_type)); so this patch uses the same guards again. Existing tests showed the need for this once polynomial constants are added. 2017-09-21 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * tree-vrp.c (extract_range_from_binary_expr_1): Check int_cst_rangeN before calling value_range_constant_singleton (&vrN).

2017-09-21enable handling of -gno- command-line options as negated prefixesAlexandre Oliva10-35/+79
This patch that adds -g to the set of negatable prefixes along with -f, -m and -W. Besides the mapping from -gno- to negated -g in option_map and adding g to the [fmW] matches for negatable options, I had to introduce gno- as an remapping prefix, for the option searching machinery to backtrack to and recognize as a remapping prefix, instead of backtracking to -g and stopping at it as if no-* was its Joined argument. Adding such remapping prefixes to preempt further backtracking can be accomplished by introducing the prefix as an Undocumented option with a Joined argument and without Driver, Target, Common, or any language-specific option. Whenever we match such a fake options prefix, we abandon further backtracking (it matches, after all), but find_opt returns the same code it would if it hadn't found any match, so that we resort to option mapping. I've arranged for such remapping prefixes to not be considered when looking for and suggesting a correct spelling for misspelled options. While testing that, I found a few -W-started options that were not marked as RejectNegative but should (-Wno-a, is not something we'd like to suggest ;-) I've also marked as such -g-started options that it makes no sense to negate, and removed the explicit -gno- ones, allowing their opposites to be negated. for gcc/ChangeLog * common.opt (Wa, Wl, Wp, g, gz=): Add RejectNegative.

2017-09-20rs6000: Don't touch below the stack pointer (PR77687)Segher Boessenkool4-4/+33
With the 32-bit SVR4 ABI we don't have a red zone, so we have to restore the callee-saved registers before we restore the stack pointer. The previous fix for this PR failed in two ways, for huge frames: first, we use a negative offset from r11 in that case, so the (mem:BLK 11) access does no good; second, sched does not handle accesses to mem:BLK correctly in this case (does not make dependencies). This patch fixes it by doing a store to (mem:BLK (scratch)) instead. This means no unrelated (not to stack) loads/stores can be moved over the stack restore either, but so be it.
