* [X86] Merge the different Jcc instructions for each condition code into ↵Craig Topper2019-04-051-4/+4
| | | | | | | | | | | | | | | | | | | | | single instructions that store the condition code as an operand. Summary: This avoids needing an isel pattern for each condition code. And it removes translation switches for converting between Jcc instructions and condition codes. Now the printer, encoder and disassembler take care of converting the immediate. We use InstAliases to handle the assembly matching. But we print using the asm string in the instruction definition. The instruction itself is marked IsCodeGenOnly=1 to hide it from the assembly parser.

* Followup on Proposal to move MIR physical register namespace to '$' sigil.Puyan Lotfi2018-01-311-12/+12
| | | | | | | | | | | | Discussed here: http://lists.llvm.org/pipermail/llvm-dev/2018-January/120320.html In preparation for adding support for named vregs we are changing the sigil for physical registers in MIR to '$' from '%'. This will prevent name clashes of named physical register with named vregs. llvm-svn: 323922
* [CodeGen] Unify MBB reference format in both MIR and debug outputFrancis Visoiu Mistrih2017-12-041-3/+3
| | | | | | | | | | | | | | | | As part of the unification of the debug format and the MIR format, print MBB references as '%bb.5'. The MIR printer prints the IR name of a MBB only for block definitions. * find . \( -name "*.mir" -o -name "*.cpp" -o -name "*.h" -o -name "*.ll" \) -type f -print0 | xargs -0 sed -i '' -E 's/BB#" << ([a-zA-Z0-9_]+)->getNumber\(\)/" << printMBBReference(*\1)/g' * find . \( -name "*.mir" -o -name "*.cpp" -o -name "*.h" -o -name "*.ll" \) -type f -print0 | xargs -0 sed -i '' -E 's/BB#" << ([a-zA-Z0-9_]+)\.getNumber\(\)/" << printMBBReference(\1)/g' * find . \( -name "*.txt" -o -name "*.s" -o -name "*.mir" -o -name "*.cpp" -o -name "*.h" -o -name "*.ll" \) -type f -print0 | xargs -0 sed -i '' -E 's/BB#([0-9]+)/%bb.\1/g' * grep -nr 'BB#' and fix Differential Revision: https://reviews.llvm.org/D40422 llvm-svn: 319665
* 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 Lorenz2015-08-131-37/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
* MIR Tests: Add liveins and successors to make tests pass with machine verifier.Alex Lorenz2015-07-241-0/+2
| | | | | | | | This commit adds the liveins and successors properties to machine basic blocks in some of the MIR tests to ensure that the tests will pass when the MIR parser will run the machine verifier after initializing a machine function. llvm-svn: 243124
* MIR Parser: Verify the implicit machine register operands.Alex Lorenz2015-07-071-6/+6
| | | | | | | | | | | | This commit verifies that the parsed machine instructions contain the implicit register operands as specified by the MCInstrDesc. Variadic and call instructions aren't verified. Reviewers: Duncan P. N. Exon Smith Differential Revision: http://reviews.llvm.org/D10781 llvm-svn: 241537
* MIR Serialization: Serialize machine basic block operands.Alex Lorenz2015-06-261-0/+75
This commit serializes machine basic block operands. The machine basic block operands use the following syntax: %bb.<id>[.<name>] This commit also modifies the YAML representation for the machine basic blocks - a new, required field 'id' is added to the MBB YAML mapping. The id is used to resolve the MBB references to the actual MBBs. And while the name of the MBB can be included in a MBB reference, this name isn't used to resolve MBB references - as it's possible that multiple MBBs will reference the same BB and thus they will have the same name. If the name is specified, the parser will verify that it is equal to the name of the MBB with the specified id. Reviewers: Duncan P. N.
