RE: [PATCH][i386,AVX] Enable VBMI2 support [5/7]

Hi Gerald, Do you think it is ok to copypaste it from GCC-6? GCC now supports the Intel CPU, named Cannonlake through -march=cannonlake. The switch enables the following ISA extensions: AVX512VBMI, AVX512IFMA, SHA. GCC now supports the Intel CPU, named and Icelake through -march=icelake. The

[RFA][PATCH][tree-optimization/78496] 03/03 Embed and exploit EVRP analysis within DOM

And finally, the meat of the fix for pr78496. This is largely the patch that was posed right when stage1 closed with just minor updates. This patch embeds evrp analysis into DOM and exploits it in the minimal way necessary to fix pr78496 without regressing other tests in the testsuite. The key

[RFA][PATCH][tree-optimization/78496] 02/03 Do not exploit __builtin_unreachable if -fsanitize=unreachable

As I brought my patches for pr78496 up to the tip of the trunk I noticed a couple testsuite regressions with -fsanitize=unreachable tests. The problem is VRP and EVRP analysis/optimization could exploit __builtin_unreachable to narrow the range of an object, then use that narrowed range to

[RFA][PATCH][tree-optimization/78496] 01/03 Do not lose range information from earlier VRP passes

As we touched on in IRC, the EVRP analyzer was doing something stupid which caused it to not merge in existing range information under certain circumstances. Consider this fragment: x_1 = foo () if (x_1 > 2) __builtin_unreachable (); if (x_1 < 0) __builtin_unreachable ();

[PATCH] enhance documentation of -Wstringop-truncation

It was suggested to me that it might be helpful to mention attribute nonstring as a solution to -Wstringop-truncation warnings. I think it's a good idea to add a reference to the attribute to the manual. The attached patch does that. Since the attribute is suitable only under rare conditions

Re: [committed] hppa: Fix bootstrap on hppa-hpux

Sorry, hit wrong button. The attached patch fixes gcc bootstrap on hppa-hpux. Revision r254585 changed the handling of scaled-index addresses. We weren't checking the base operand to ensure that the REG_POINTER flag was set prior to load. As a result, we accepted invalid base register
