From e78e52ba9b0f7e2dacada0f47711207b69922b93 Mon Sep 17 00:00:00 2001 From: Hal Finkel Date: Thu, 12 Mar 2015 20:09:39 +0000 Subject: [PATCH] Revert "r232027 - Add infrastructure for support of multiple memory constraints" This (r232027) has caused PR22883; so it seems those bits might be used by something else after all. Reverting until we can figure out what else to do. Original commit message: 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. llvm-svn: 232093 --- llvm/include/llvm/CodeGen/SelectionDAGISel.h | 4 +-- llvm/include/llvm/IR/InlineAsm.h | 38 ---------------------- llvm/include/llvm/Target/TargetLowering.h | 7 ---- .../CodeGen/SelectionDAG/SelectionDAGBuilder.cpp | 12 ------- llvm/lib/CodeGen/SelectionDAG/SelectionDAGISel.cpp | 4 +-- llvm/lib/Target/AArch64/AArch64ISelDAGToDAG.cpp | 7 ++-- llvm/lib/Target/ARM/ARMISelDAGToDAG.cpp | 7 ++-- llvm/lib/Target/Hexagon/HexagonISelDAGToDAG.cpp | 12 +++---- llvm/lib/Target/MSP430/MSP430ISelDAGToDAG.cpp | 8 ++--- llvm/lib/Target/Mips/MipsISelDAGToDAG.cpp | 5 ++- llvm/lib/Target/Mips/MipsISelDAGToDAG.h | 2 +- llvm/lib/Target/NVPTX/NVPTXISelDAGToDAG.cpp | 6 ++-- llvm/lib/Target/NVPTX/NVPTXISelDAGToDAG.h | 2 +- llvm/lib/Target/PowerPC/PPCISelDAGToDAG.cpp | 2 +- llvm/lib/Target/Sparc/SparcISelDAGToDAG.cpp | 8 ++--- llvm/lib/Target/SystemZ/SystemZISelDAGToDAG.cpp | 7 ++-- llvm/lib/Target/X86/X86ISelDAGToDAG.cpp | 12 +++---- llvm/lib/Target/XCore/XCoreISelDAGToDAG.cpp | 8 ++--- 18 files changed, 44 insertions(+), 107 deletions(-) diff --git a/llvm/include/llvm/CodeGen/SelectionDAGISel.h b/llvm/include/llvm/CodeGen/SelectionDAGISel.h index 7acdfc7..d53e66d 100644 --- a/llvm/include/llvm/CodeGen/SelectionDAGISel.h +++ b/llvm/include/llvm/CodeGen/SelectionDAGISel.h @@ -80,12 +80,12 @@ public: virtual SDNode *Select(SDNode *N) = 0; /// SelectInlineAsmMemoryOperand - Select the specified address as a target - /// addressing mode, according to the specified constraint.
