* SelectionDAG: Make Properties a field of SDPatternOperatorMatt Arsenault2016-02-101-1/+1
| | | | | | | | | Currently you can't specify node properties like commutativity on a PatFrag. If you want to create a PatFrag on a commutative node with a hasOneUse predicate, this enables you to specify that the PatFrag is also commutable. llvm-svn: 260404
* TableGen: Add IsOptional field to AsmOperandClassTom Stellard2016-02-051-1/+15
| | | | | | | | | | | | | | | Summary: This makes it possible to specify some operands as optional to the AsmMatcher. Setting this field to true will prevent the AsmMatcher from emitting 'too few operands' errors when there are missing optional operands.

* Minor performance tweaks to llvm-tblgen (and a few that might be a good idea)Reid Kleckner2016-02-032-2/+5
| | | | | | | | | | | | | | | | | | | | | | | | | Summary: This patch adds a reserve call to an expensive function (`llvm::LoadIntrinsics`), and may fix a few other low hanging performance fruit (I've put them in comments for now, so we can discuss). **Motivation:** As I'm sure other developers do, when I build LLVM, I build the entire project with the same config (`Debug`, `MinSizeRel`, `Release`, or `RelWithDebInfo`). However, the `Debug` config also builds llvm-tblgen in `Debug` mode. Later build steps that run llvm-tblgen then can actually be the slowest steps in the entire build. Nobody likes slow builds.

* [TableGen] Add 'register alternative name matching' supportDylan McKay2016-02-031-0/+34
| | | | | | | | | | | | | | | | | Summary: This adds a new attribute which targets can set in TableGen which causes a function to be generated which matches register alternative names. This is very similar to `ShouldEmitMatchRegisterName`, except it works on alt names. This patch is currently used by the out of tree part of the AVR backend. It reduces code duplication greatly, and has the effect that you do not need to hardcode altname to register mappings in C++. It will not work on targets which have registers which share the same aliases.

* [llvm-tblgen] Avoid StringMatcher for GCC and MS builtin namesReid Kleckner2016-01-271-91/+56
| | | | | | | | | | | | | | | This brings the compile time of Function.cpp from ~40s down to ~4s for me locally. It also shaves off about 400KB of object file size in a release+asserts build. I also realized that the AMDGPU backend does not have any GCC builtin names to match, so the extra lookup was a no-op. I removed it to silence a zero-length string table array warning. There should be no functional change here. This change really ends the story of PR11951. llvm-svn: 258897
* [llvm-tblgen] Stop emitting the intrinsic name matching codeReid Kleckner2016-01-261-60/+0
| | | | | | | | | The AMDGPU backend was the last user of the old StringMatcher recognition code. Move it over to the new lookupLLVMIntrinsicName funciton, which is now improved to handle all of the interesting edge cases exposed by AMDGPU intrinsic names. llvm-svn: 258875
* Remove autoconf supportChris Bieneman2016-01-261-18/+0
| | | | | | | | | | | | | | | | Summary: This patch is provided in preparation for removing autoconf on 1/26. The proposal to remove autoconf on 1/26 was discussed on the llvm-dev thread here: http://lists.llvm.org/pipermail/llvm-dev/2016-January/093875.html "I felt a great disturbance in the [build system], as if millions of [makefiles] suddenly cried out in terror and were suddenly silenced.

* Sort intrinsics by LLVM intrinsic name, rather than tablegen def nameReid Kleckner2016-01-261-0/+4
| | | | | | | | | | | | Step one towards using a simple binary search to lookup intrinsic IDs instead of our crazy table generated switch+memcmp+startswith code that makes Function.cpp take about a minute to compile. See PR24785 and PR11951 for why we should do this. The X86 backend contains tables that need to be sorted on intrinsic ID, so reorder those. llvm-svn: 258757
* [TableGen] Fix sort order of asm operand classesOliver Stannard2016-01-251-20/+85
| | | | | | | | | | | | | | | | | | | | | | This is a fix for https://llvm.org/bugs/show_bug.cgi?id=22796. The previous implementation of ClassInfo::operator< allowed cycles of classes such that x < y < z < x, meaning that a list of them cannot be correctly sorted, and the sort order could differ with different standard libraries. The original implementation sorted classes by ValueName if they were otherwise equal. This isn't strictly necessary, but some backends seem to accidentally rely on it. If I reverse this comparison I get 8 test failures spread across the AArch64, Mips and X86 backends, so I have left it in until those backends can be fixed. There was one case in the X86 backend where the observable behaviour of the assembler is changed by this patch. This was because some of the memory asm operands were not marked as children of X86MemAsmOperand. Differential Revision: http://reviews.llvm.org/D16141 llvm-svn: 258677
* [TableGen] In AsmWriterEmitter unique command search, rather than storing a ↵Craig Topper2016-01-241-43/+32
