* Revert "[mips] Fix c.<cc>.<fmt> instruction definition."Simon Dardis2016-09-091-0/+1
| | | | | | | This reverts commit r281022. Mips buildbot broke, due to unhandled register class FCC. llvm-svn: 281033
* [mips] Fix c.<cc>.<fmt> instruction definition.Simon Dardis2016-09-091-1/+0
| | | | | | | | | | | | | | | As part of this effort, remove MipsFCmp nodes and use tablegen patterns rather than custom lowering through C++. Unexpectedly, this improves codesize for microMIPS as previous floating point setcc expansions would materialize 0 and 1 into GPRs before using the relevant mov[tf].[sd] instruction. Now $zero is used directly. Reviewers: dsanders, vkalintiris, zoran.jovanovic Differential Review: https://reviews.llvm.org/D23118 llvm-svn: 281022
* [mips] Range check uimm20 and fixed a bug this revealed.Daniel Sanders2016-02-291-2/+2
| | | | | | | | | | | | | | | | | | | Summary: The bug was that dextu's operand 3 would print 0-31 instead of 32-63 when printing assembly. This came up when replacing MipsInstPrinter::printUnsignedImm() with a version that could handle arbitrary bit widths. MipsAsmPrinter::printUnsignedImm*() don't seem to be used so they have been removed.

* [MCInstPrinter] Enable MCInstPrinter to change its behavior based on theAkira Hatanaka2015-03-271-1/+2
| | | | | | | | | | | | | | | | | | | | per-function subtarget. Currently, code-gen passes the default or generic subtarget to the constructors of MCInstPrinter subclasses (see LLVMTargetMachine::addPassesToEmitFile), which enables some targets (AArch64, ARM, and X86) to change their instprinter's behavior based on the subtarget feature bits. Since the backend can now use different subtargets for each function, instprinter has to be changed to use the per-function subtarget rather than the default subtarget. This patch takes the first step towards enabling instprinter to change its behavior based on the per-function subtarget. It adds a bit "PassSubtarget" to AsmWriter which tells table-gen to pass a reference to MCSubtargetInfo to the various print methods table-gen auto-generates. I will follow up with changes to instprinters of AArch64, ARM, and X86. llvm-svn: 233411

* Canonicalize header guards into a common format.Benjamin Kramer2014-08-131-2/+2
| | | | | | | | | | Add header guards to files that were missing guards. Remove #endif comments as they don't seem common in LLVM (we can easily add them back if we decide they're useful) Changes made by clang-tidy with minor tweaks. llvm-svn: 215558

* This patch that sets the EmitAlias flag in td files Jack Carter2013-02-051-0/+2
| | | | | | | | | | | | | and enables the instruction printer to print aliased instructions. Due to usage of RegisterOperands a change in common code (utils/TableGen/AsmWriterEmitter.cpp) is required to get the correct register value if it is a RegisterOperand.

* This patch tackles the problem of parsing Mips Jack Carter2013-01-121-0/+1
| | | | | | | | | | | | | | | | | | register names in the standalone assembler llvm-mc. Registers such as $A1 can represent either a 32 or 64 bit register based on the instruction using it. In addition, based on the abi, $T0 can represent different 32 bit registers. The problem is resolved by the Mips specific AsmParser td definitions changing to work together. Many cases of RegisterClass parameters are now RegisterOperand. Contributer: Vladimir Medic llvm-svn: 172284
