* [TableGen] Correct Namespace lookup with AltNames in AsmWriterEmitterHal Finkel2015-12-111-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | AsmWriterEmitter will generate a getRegisterName function with an alternate register name index as its second argument if the target makes use of them. The enum of these values is generated in RegisterInfoEmitter. The getRegisterName generator would assume the namespace could always be found by reading index 1 of the list of AltNameIndices, but this will fail if this list is sorted such that the NoRegAltName is at index 1. Because this list is sorted by record name (in CodeGenTarget::ReadRegAltNameIndices), you only run in to problems if your MyTargetRegisterInfo.td defines a single RegAltNameIndex that sorts lexically before NoRegAltName. For example, if a target has something like def AnAltNameIndex : RegAltNameIndex and defines RegAltNameIndices for some registers then, prior to this change, AsmWriterEmitter would generate references to ::AnAltNameIndex and ::NoRegAltName Patch by Alex Bradbury! llvm-svn: 255344
* [AArch64] Add ARMv8.2-A Statistical Profiling ExtensionOliver Stannard2015-12-011-5/+7
| | | | | | | | | | | | The Statistical Profiling Extension is an optional extension to ARMv8.2-A. Since it is an optional extension, I have added the FeatureSPE subtarget feature to control it. The assembler-visible parts of this extension are the new "psb csync" instruction, which is equivalent to "hint #17", and a number of system registers.

* Remove and forbid raw_svector_ostream::flush() calls.Yaron Keren2015-08-131-1/+0
| | | | | | | | | | After r244870 flush() will only compare two null pointers and return, doing nothing but wasting run time. The call is not required any more as the stream and its SmallString are always in sync. Thanks to David Blaikie for reviewing. llvm-svn: 244928

| | | | | | | | | | | | | | | | | | | | If the type isn't trivially moveable emplace can skip a potentially expensive move. It also saves a couple of characters. Call sites were found with the ASTMatcher + some semi-automated cleanup. memberCallExpr( argumentCountIs(1), callee(methodDecl(hasName("push_back"))), on(hasType(recordDecl(has(namedDecl(hasName("emplace_back")))))), hasArgument(0, bindTemporaryExpr( hasType(recordDecl(hasNonTrivialDestructor())), has(constructExpr()))), unless(isInTemplateInstantiation())) No functional change intended. llvm-svn: 238602
* [MCInstPrinter] Enable MCInstPrinter to change its behavior based on theAkira Hatanaka2015-03-271-7/+20
| | | | | | | | | | | | | | | | | | | | 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

* Replace size method call of containers to empty method where appropriateAlexander Kornienko2015-01-151-2/+2
| | | | | | | | | | | | | | | | This patch was generated by a clang tidy checker that is being open sourced. The documentation of that checker is the following: /// The emptiness of a container should be checked using the empty method /// instead of the size method. It is not guaranteed that size is a /// constant-time function, and it is generally more efficient and also shows /// clearer intent to use empty. Furthermore some containers may implement the /// empty method but not implement the size method. Using empty whenever /// possible makes it easier to switch to another container in the future. Patch by Gábor Horváth! llvm-svn: 226161
* On behalf of Matthew Wahab:Evgeny Astigeevich2014-12-161-1/+7
| | | | | | | | | | | | | | | | An instruction alias defined with InstAlias and an optional operand in the middle of the AsmString field, "..${a} <operands>", would get the final "}" printed in the instruction disassembly. This wouldn't happen if the optional operand appeared as the last item in the AsmString which is how the current backends avoided the problem. There don't appear to be any tests for this part of Tablegen but it passes the pre-commit tests. Manually tested the change by enabling the generic alias printer in the ARM backend and checking the output. Differential Revision: http://reviews.llvm.org/D6529 llvm-svn: 224348

* Condition codes AL and NV are invalid in the aliases that useArtyom Skrobov2014-06-101-3/+46
| | | | | | | | | | | | | | inverted condition codes (CINC, CINV, CNEG, CSET, and CSETM). Matching aliases based on "immediate classes", when disassembling, wasn't previously supported, hence adding MCOperandPredicate into class Operand, and implementing the support for it in AsmWriterEmitter. The parsing for those aliases was already custom, so just adding the missing condition into AArch64AsmParser::parseCondCode. llvm-svn: 210528

* TableGen: convert InstAlias's Emit bit to an int.Tim Northover2014-05-201-13/+31
| | | | | | | | | | | | | When multiple aliases overlap, the correct string to print can often be determined purely by considering the InstAlias declarations in some particular order. This allows the user to specify that order manually when desired, without resorting to hacking around with the default lexicographical order on Record instantiation, which is error-prone and ugly. I was also mistaken about "add w2, w3, w4" being the same as "add w2, w3, w4, uxtw". That's only true if Rn is the stack pointer. llvm-svn: 209199
* TableGen: fix operand counting for aliasesTim Northover2014-05-161-32/+7
| | | | | | | | | | | | | | | | | | | | | TableGen has a fairly dubious heuristic to decide whether an alias should be printed: does the alias have lest operands than the real instruction. This is bad enough (particularly with no way to override it), but it should at least be calculated consistently for both strings. This patch implements that logic: first get the *correct* string for the variant, in the same way as the Matcher, without guessing; then count the number of whitespace chars. There are basically 4 changes this brings about after the previous commits; all of these appear to be good, so I have changed the tests: + ARM64: we print "neg X, Y" instead of "sub X, xzr, Y". + ARM64: we skip implicit "uxtx" and "uxtw" modifiers. + Sparc: we print "mov A, B" instead of "or %g0, A, B". + Sparc: we print "fcmpX A, B" instead of "fcmpX %fcc0, A, B" llvm-svn: 208969
