The following changes are necessasy to get the generated tree
matcher to compile:
- In CodeExpansions::declare(), the assert() prevents connecting
two instructions. E.g. the match code
(match (MUL $t, $s1, $s2),
(SUB $d, $t, $s3)),
results in two declarations of $t, one for the def and one for
the use. Removing the assertion allows this construct.
If $t is later used, it is one of the operands, which should be
perfectly fine.
- The code emitted in GIMatchTreeVRegDefPartitioner::generatePartitionSelectorCode()
is not compilable:
- The value of NewInstrID should be emitted, not the name
- Both calls involving getOperand() end with one parenthesis too many
- Swaps generated condition for the partition code in the latter function
It also changes the rules i2p_to_p2i, fabs_fabs_fold, and fneg_fneg_fold
to use the tree matcher for a linear match. These rules are tested by:
CodeGen/AArch64/GlobalISel/combine-fabs.mir
CodeGen/AArch64/GlobalISel/combine-fneg.mir
CodeGen/AArch64/GlobalISel/combine-ptrtoint.mir
CodeGen/AMDGPU/GlobalISel/combine-add-nullptr.mir

Summary:
This will handle expansion of C++ fragments in the declarative combiner
including custom predicates, and escapes into C++ to aid the migration
effort.
Fixed the -DLLVM_LINK_LLVM_DYLIB=ON using DISABLE_LLVM_LINK_LLVM_DYLIB when
creating the library. Apparently it automatically links to libLLVM.dylib
and we don't want that from tablegen.
