* Changed the TableGen created MatchInstructionImpl() setting of ErrorInfo.Kevin Enderby2011-02-021-3/+1
| | | | | | | | | | | | The algorithm for identifying which operand is invalid will now always point to some operand and not the mnemonic sometimes. The change is now that ErrorInfo is the index of the highest operand that does not match for any of the matching mnemonics records. And no longer the ~0U value when the mnemonic matches and not every record with a matching mnemonic has the same mismatching operand index. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@124734 91177308-0d34-0410-b5e6-96231b3b80d8

* [AVX] Implement EnforceSmallerThan for mixed int/fp type lists. ThisDavid Greene2011-02-011-27/+130
| | | | | | | | | | | | | | makes type checking for extract_subvector and insert_subvector more robust and will allow stricter typechecking of more patterns in the future. This change handles int and fp as disjoint sets so that it will enforce integer types to be smaller than the largest integer type and fp types to be smaller than the largest fp type. There is no attempt to check type sizes across the int/fp sets. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@124672 91177308-0d34-0410-b5e6-96231b3b80d8

* Improve the AsmMatcher's ability to handle suboperands.Bob Wilson2011-01-263-172/+247
| | | | | | | | | | | | | | | When an operand class is defined with MIOperandInfo set to a list of suboperands, the AsmMatcher has so far required that operand to also define a custom ParserMatchClass, and InstAlias patterns have not been able to set the individual suboperands separately. This patch removes both of those restrictions. If a "compound" operand does not override the default ParserMatchClass, then the AsmMatcher will now parse its suboperands separately. If an InstAlias operand has the same class as the corresponding compound operand, then it will be handled as before; but if that check fails, TableGen will now try to match up a sequence of InstAlias operands with the corresponding suboperands. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@124314 91177308-0d34-0410-b5e6-96231b3b80d8

* When matching asm operands, always try to match the most restricted type first.Owen Anderson2011-01-181-3/+36
| | | | | | | | | | | | | Unfortunately, while this is the "right" thing to do, it breaks some ARM asm parsing tests because MemMode5 and ThumbMemModeReg are ambiguous. This is tricky to resolve since neither is a subset of the other. XFAIL the test for now. The old way was broken in other ways, just ways we didn't happen to be testing, and our ARM asm parsing is going to require significant revisiting at a later point anyways. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@123786 91177308-0d34-0410-b5e6-96231b3b80d8
