* [Alignment] Use llvm::Align in MachineFunction and TargetLowering - fixes ↵Guillaume Chatelet2019-09-111-4/+4
| | | | | | | | | | | | | | | | | | | | | | 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
* MIR: Allow parsing of empty machine functionsJustin Bogner2017-04-111-9/+1
| | | | | | | | | | | | If you run llc -stop-after=codegenprepare and feed the resulting MIR to llc -start-after=codegenprepare, you'll have an empty machine function since we haven't run any isel yet. Of course, this only works if the MIRParser believes you that this is okay. This is essentially a revert of r241862 with a fix for the problem it was papering over. llvm-svn: 299975
* MIRParser/MIRPrinter: Compute HasInlineAsm instead of printing/parsing itMatthias Braun2016-08-241-5/+0

* llc: Add support for -run-pass noneMatthias Braun2016-07-161-1/+1
| | | | | | | | | | This does not schedule any passes besides the ones necessary to construct and print the machine function. This is useful to test .mir file reading and printing. Differential Revision: http://reviews.llvm.org/D22432 llvm-svn: 275664
* [MIR] Print on the given output instead of stderr.Quentin Colombet2016-07-131-1/+1
| | | | | | | | | | | | Currently the MIR framework prints all its outputs (errors and actual representation) on stderr. This patch fixes that by printing the regular output in the output specified with -o. Differential Revision: http://reviews.llvm.org/D22251 llvm-svn: 275314
* When printing MIR, output to errs() rather than outs().Justin Lebar2016-02-191-1/+1
| | | | | | | | | | | | | | | | | | | | | Summary: Without this, this command $ llvm-run llc -stop-after machine-cp -o - <( echo '' ) outputs an error, because we close stdout twice -- once when closing the file opened for "-o", and again when closing outs(). Also clarify in the outs() definition that you can't ever call it if you want to open your own raw_fd_ostream on stdout.

* MIR Serialization: Change MIR syntax - use custom syntax for MBBs.Alex Lorenz2015-08-131-8/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit modifies the way the machine basic blocks are serialized - now the machine basic blocks are serialized using a custom syntax instead of relying on YAML primitives. Instead of using YAML mappings to represent the individual machine basic blocks in a machine function's body, the new syntax uses a single YAML block scalar which contains all of the machine basic blocks and instructions for that function. This is an example of a function's body that uses the old syntax: body: - id: 0 name: entry instructions: - '%eax = MOV32r0 implicit-def %eflags' - 'RETQ %eax' ... The same body is now written like this: body: | bb.0.entry: %eax = MOV32r0 implicit-def %eflags RETQ %eax ... This syntax change is motivated by the fact that the bundled machine instructions didn't map that well to the old syntax which was using a single YAML sequence to store all of the machine instructions in a block. The bundled machine instructions internally use flags like BundledPred and BundledSucc to determine the bundles, and serializing them as MI flags using the old syntax would have had a negative impact on the readability and the ease of editing for MIR files. The new syntax allows me to serialize the bundled machine instructions using a block construct without relying on the internal flags, for example: BUNDLE implicit-def dead %itstate, implicit-def %s1 ... { t2IT 1, 24, implicit-def %itstate %s1 = VMOVS killed %s0, 1, killed %cpsr, implicit killed %itstate } This commit also converts the MIR testcases to the new syntax. I developed a script that can convert from the old syntax to the new one. I will post the script on the llvm-commits mailing list in the thread for this commit. llvm-svn: 244982
* Move generic MIR tests in their own subdir, requires "native" as wellMehdi Amini2015-08-041-0/+66
These tests rely on the native backend to be built-in. From: Mehdi Amini <mehdi.amini@apple.com> llvm-svn: 243959
