* [tablegen][globalisel] Add support for nested instruction matching.Daniel Sanders2017-04-041-13/+180
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: Lift the restrictions that prevented the tree walking introduced in the previous change and add support for patterns like: (G_ADD (G_MUL (G_SEXT $src1), (G_SEXT $src2)), $src3) -> SMADDWrrr $dst, $src1, $src2, $src3 Also adds support for G_SEXT and G_ZEXT to support these cases. One particular aspect of this that I should draw attention to is that I've tried to be overly conservative in determining the safety of matches that involve non-adjacent instructions and multiple basic blocks. This is intended to be used as a cheap initial check and we may add a more expensive check in the future. The current rules are: * Reject if any instruction may load/store (we'd need to check for intervening memory operations. * Reject if any instruction has implicit operands. * Reject if any instruction has unmodelled side-effects. See isObviouslySafeToFold().

| | | | | | | | | | | | | | | | | | | | | This is needed by TestCases/Posix/coverage-direct.cc The problem is that the test does: mkdir <dir> cd <dir> cd .. rm -rf <dir> <more commands> the current directory currently looks like "/.../<dir>/../" which doesn't exist when dir is deleted. at some point we should probably switch to using the os current directory (specially if we want to add subshell), but this is a small incremental improvement. llvm-svn: 299113

* Rename AttributeSet to AttributeListReid Kleckner2017-03-211-10/+10
| | | | | | | | | | | | | | | | | | | | | | | | | Summary: This class is a list of AttributeSetNodes corresponding the function prototype of a call or function declaration. This class used to be called ParamAttrListPtr, then AttrListPtr, then AttributeSet. It is typically accessed by parameter and return value index, so "AttributeList" seems like a more intuitive name. Rename AttributeSetImpl to AttributeListImpl to follow suit. It's useful to rename this class so that we can rename AttributeSetNode to AttributeSet later. AttributeSet is the set of attributes that apply to a single function, argument, or return value.

| | | | | | | | | | These are needed due to some obscure rules in the standard about how std::vector selects between copy and move constructors, which can cause a conforming implementation to attempt to select the copy constructor of RuleMatcher, which will fail since std::unique_ptr<> isn't copyable. llvm-svn: 298294
* [tablegen][globalisel] Capture instructions into locals and related ↵Daniel Sanders2017-03-201-60/+125
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | infrastructure for multiple instructions matches. Summary: Prepare the way for nested instruction matching support by having actions like CopyRenderer look up operands in the RuleMatcher rather than a specific InstructionMatcher. This allows actions to reference any operand from any matched instruction. It works by checking the 'shape' of the match and capturing each matched instruction to a local variable. If the shape is wrong (not enough operands, leaf nodes where non-leafs are expected, etc.), then the rule exits early without checking the predicates. Once we've captured the instructions, we then test the predicates as before (except using the local variables). If the match is successful, then we render the new instruction as before using the local variables. It's not noticable in this patch but by the time we support multiple instruction matching, this patch will also cause a significant improvement to readability of the emitted code since MRI.getVRegDef(I->getOperand(0).getReg()) will simply be MI1 after emitCxxCaptureStmts(). This isn't quite NFC because I've also fixed a bug that I'm surprised we haven't encountered yet. It now checks there are at least the expected number of operands before accessing them with getOperand().

Currently we don't enforce that ISD::ANY_EXTEND, ZERO_EXTEND, SIGN_EXTEND, TRUNC, FP_ROUND, FP_EXTEND have the same number of elements(including scalar) between their input and output. Though we have them documented as such. Up until a few months ago x86 created nodes that violated this rule. That's all been fixed now, and we should enforce the rule going forward. In order to do this we need to allow SDTCisSameNumEltsAs to support scalar types and not enforce being a vector. If one type is scalar we will force the other type to also be scalar.
