2006-11-15Switch loads over to use memri as the operand instead of a reg/imm operandChris Lattner
pair for cleanliness. Add instructions for PPC32 preinc-stores with commented out patterns. More improvement is needed to enable the patterns, but we're getting close. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@31749 91177308-0d34-0410-b5e6-96231b3b80d8

2006-11-14Fix predicates for unindexed stores so they don't accidentally match indexedChris Lattner
stores. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@31735 91177308-0d34-0410-b5e6-96231b3b80d8
2006-11-14Rework PPC64 calls. Now we have a LR8/CTR8 register which the PPC64 callsChris Lattner
clobber. This allows LR8 to be save/restored correctly as a 64-bit quantity, instead of handling it as a 32-bit quantity. This unbreaks ppc64 codegen when the code is actually located above the 4G boundary. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@31734 91177308-0d34-0410-b5e6-96231b3b80d8
2006-11-14remove a ton of custom selection logic no longer neededChris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@31733 91177308-0d34-0410-b5e6-96231b3b80d8
2006-11-14Fix a bug handling nodes with variable arguments. The code was fixed to assumeChris Lattner
that there were two input operands before the variable operand portion. This *happened* to be true for all call instructions, which took a chain and a destination, but was not true for the PPC BCTRL instruction, whose destination is implicit. Making this code more general allows elimination of the custom selection logic for BCTRL. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@31732 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@31726 91177308-0d34-0410-b5e6-96231b3b80d8
2006-11-14lower "X = seteq Y, Z" to '(shr (ctlz (xor Y, Z)), 5)' instead ofChris Lattner
'(shr (ctlz (sub Y, Z)), 5)'. The use of xor better exposes the operation to bit-twiddling logic in the dag combiner. For example, this: typedef struct { unsigned prefix : 4; unsigned code : 4; unsigned unsigned_p : 4; } tree_common; int foo(tree_common *a, tree_common *b) { return a->code == b->code; } Now compiles to: _foo: lwz r2, 0(r4) lwz r3, 0(r3) xor r2, r3, r2 rlwinm r2, r2, 28, 28, 31 cntlzw r2, r2 srwi r3, r2, 5 blr instead of: _foo: lbz r2, 3(r4) lbz r3, 3(r3) srwi r2, r2, 4 srwi r3, r3, 4 subf r2, r2, r3 cntlzw r2, r2 srwi r3, r2, 5 blr saving a cycle. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@31725 91177308-0d34-0410-b5e6-96231b3b80d8
