The operand flag word for ISD::INLINEASM nodes now contains a 15-bit memory constraint ID when the operand kind is Kind_Mem. This constraint ID is a numeric equivalent to the constraint code string and is converted with a target specific hook in TargetLowering. This patch maps all memory constraints to InlineAsm::Constraint_m so there is no functional change at this point. It just proves that using these previously unused bits in the encoding of the flag word doesn't break anything. The next patch will make each target preserve the current mapping of everything to Constraint_m for itself while changing the target independent implementation of the hook to return Constraint_Unknown appropriately. Each target will then be adapted in separate patches to use appropriate Constraint_* values. PR22883 was caused the matching operands copying the whole of the operand flags for the matched operand. This included the constraint id which needed to be replaced with the operand number. This has been fixed with a conversion function. Following on from this, matching operands also used the operand number as the constraint id. This has been fixed by looking up the matched operand and taking it from there. llvm-svn: 232165 |
