Revert "Revert "Reland "[Support] make report_fatal_error `abort` instead of `exit`""" This reverts commit 80a34ae31125aa46dcad47162ba45b152aed968d with fixes. Previously, since bots turning on EXPENSIVE_CHECKS are essentially turning on MachineVerifierPass by default on X86 and the fact that inline-asm-avx-v-constraint-32bit.ll and inline-asm-avx512vl-v-constraint-32bit.ll are not expected to generate functioning machine code, this would go down to `report_fatal_error` in MachineVerifierPass. Here passing `-verify-machineinstrs=0` to make the intent explicit.

[mips] Pick the right variant of DINS upfront and enable target instruction verification This patch complements D16810 "[mips] Make isel select the correct DEXT variant up front.". Now ISel picks the right variant of DINS, so now there is no need to replace DINS with the appropriate variant during MipsMCCodeEmitter::encodeInstruction(). This patch also enables target specific instruction verification for ins, dins, dinsm, dinsu, ext, dext, dextm, dextu. These instructions have constraints that are checked when generating MipsISD::Ins and MipsISD::Ext nodes, but these constraints are not checked during instruction selection. Adding machine verification should catch outstanding cases. Finally, correct a bug that instruction verification uncovered, where the position operand of a DINSU generated during lowering was being silently and accidently corrected to the correct value.

Reland "[mips] Fix the target specific instruction verifier" Fix an off by one error in the bounds checking for 'dinsu' and update the ranges in the test comments so that they are accurate. This version has the correct commit message. Reviewers: atanasyan Differential Revision: https://reviews.llvm.org/D41183 llvm-svn: 320991

[Alignment] Use llvm::Align in MachineFunction and TargetLowering - fixes mir parsing Summary: This catches malformed mir files which specify alignment as log2 instead of pow2. See https://reviews.llvm.org/D65945 for reference, This is patch is part of a series to introduce an Alignment type. See this thread for context: http://lists.llvm.org/pipermail/llvm-dev/2019-July/133851.html See this patch for the introduction of the type: https://reviews.llvm.org/D64790 Reviewers: courbet Subscribers: MatzeB, qcolombet, dschuff, arsenm, sdardis, nemanjai, jvesely, nhaehnle, hiraditya, kbarton, asb, rbar, johnrusso, simoncook, apazos, sabuasal, niosHD, jrtc27, MaskRay, zzheng, edward-jones, atanasyan, rogfer01, MartinMosbeck, brucehoult, the_o, PkmX, jocewei, jsji, Petar.Avramovic, asbirlea, s.egerton, pzheng, llvm-commits Tags: #llvm Differential Revision: https://reviews.llvm.org/D67433 llvm-svn: 371608

Followup on Proposal to move MIR physical register namespace to '$' sigil. Discussed here: http://lists.llvm.org/pipermail/llvm-dev/2018-January/120320.html In preparation for adding support for named vregs we are changing the sigil for physical registers in MIR to '$' from '%'. This will prevent name clashes of named physical register with named vregs. llvm-svn: 323922
