git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@143634 91177308-0d34-0410-b5e6-96231b3b80d8
2011-11-02The TableGen parts of the CMake build are seriously broken. This fixesChandler Carruth
one aspect of them by having them use the (annoying, if not broken) proper library dependency model for adding the LLVMTableGen library as a dependency. This could manifest as a link order issue in the presence of separate LLVM / Clang source builds with CMake and a linker that really cares about such things. Also, add the Support dependency to llvm-tblgen itself so that it doesn't rely on TableGen's transitive Support dependency. A parallel change for clang-tblgen will be forthcoming. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@143531 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-28Allow InstAlias's to use immediate matcher patterns that xform the value.Jim Grosbach
For example, On ARM, "mov r3, #-3" is an alias for "mvn r3, #2", so we want to use a matcher pattern that handles the bitwise negation when mapping to t2MVNi. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@143233 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-28Allow register classes to match a containing class in InstAliases.Jim Grosbach
If the register class in the source alias is a subclass of the register class of the actual instruction, the alias can still match OK since the constraints are strictly a subset of what the instruction can actually handle. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@143200 91177308-0d34-0410-b5e6-96231b3b80d8

2011-10-21ARM VLD parsing and encoding.Jim Grosbach
Next step in the ongoing saga of NEON load/store assmebly parsing. Handle VLD1 instructions that take a two-register register list. Adjust the instruction definitions to only have the single encoded register as an operand. The super-register from the pseudo is kept as an implicit def, so passes which come after pseudo-expansion still know that the instruction defines the other subregs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142670 91177308-0d34-0410-b5e6-96231b3b80d8

NEON immediates are "interesting". Start of the work to handle parsing them in an 'as' compatible manner.

2011-10-16Add X86 BEXTR instruction. This instruction uses VEX.vvvv to encode Operand ↵Craig Topper

2011-10-14Ban rematerializable instructions with side effects.Jakob Stoklund Olesen
TableGen infers unmodeled side effects on instructions without a pattern. Fix some instruction definitions where that was overlooked. Also raise an error if a rematerializable instruction has unmodeled side effects.

2011-10-10Emit full ED initializers even for pseudo-instructions.Jakob Stoklund Olesen
This should unbreak the picky buildbots. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@141575 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-10Insert dummy ED table entries for pseudo-instructions.Jakob Stoklund Olesen
The table is indexed by opcode, so simply removing pseudo-instructions creates a wrong mapping from opcode to table entry. Add a test case for xorps which has a very high opcode that exposes this problem. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@141562 91177308-0d34-0410-b5e6-96231b3b80d8

2011-10-07Revert part of r141274. Only need to change encoding for xchg %eax, %eax in ↵Craig Topper
64-bit mode. This is because in 64-bit mode xchg %eax, %eax implies zeroing the upper 32-bits of RAX which makes it not a NOP. In 32-bit mode using NOP encoding is fine. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@141353 91177308-0d34-0410-b5e6-96231b3b80d8

2011-10-06Fix assembling of xchg %eax, %eax to not use the NOP encoding of 0x90. This ↵Craig Topper
was done by creating a new register group that excludes AX registers. Fixes PR10345. Also added aliases for flipping the order of the operands of xchg <reg>, %eax. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@141274 91177308-0d34-0410-b5e6-96231b3b80d8

2011-10-06Remove the TRI::getSubRegisterRegClass() hook.Jakob Stoklund Olesen
This restores my karma after I added TRI::getSubClassWithSubReg(). Register constraints are applied 'backwards'. Starting from the register class required by an instruction operand, the correct question is: 'How can I constrain the super-register register class so all its sub-registers satisfy the instruction constraint?' The getMatchingSuperRegClass() hook answers that. We never need to go 'forwards': Starting from a super-register register class, what register class are the sub-registers in? The getSubRegisterRegClass() hook did that. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@141258 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-05Add TRI::getSubClassWithSubReg(RC, Idx) function.Jakob Stoklund Olesen
This function is used to constrain a register class to a sub-class that supports the given sub-register index. For example, getSubClassWithSubReg(GR32, sub_8bit) -> GR32_ABCD. The function will be used to compute register classes when emitting INSERT_SUBREG and EXTRACT_SUBREG nodes and for register class inflation of sub-register operations. The version provided by TableGen is usually adequate, but targets can override. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@141142 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-04Properly use const_iterator.Jakob Stoklund Olesen
This should unbreak the Windows build. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@141105 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-04Teach TableGen to infer missing register classes.Jakob Stoklund Olesen
The set of register classes should be closed under sub-register operations and intersections. That will allow the register allocator to model combinations of constraints accurately. This patch implements the easiest form of register class inference: For every register class, and for every sub-register SubIdx, the subset of registers in RC that have a SubIdx sub-register should also be a register class. This does create some new register classes for the targets in the tree: ARM gets a new QQQQPR_with_ssub_0. This class was omitted from the .td file on purpose because it only has two registers. InstrEmitter and RegisterCoalescer have safeguards against selecting too small register classes, so it is harmless. PowerPC gets a G8RC_with_sub_32 class because LR is not a sub_32 sub-register of LR8. I think that might be an omission? X86 puts RIP in the GR64 class, and since that register doesn't have 8-bit sub-registers, we get: GR64_with_sub_8bit GR64_TC_with_sub_8bit GR64_NOREX_with_sub_8bit GR64_TC_with_sub_8bit_hi The various CodeGen classes have already been fixed so adding new register classes should not affect compile time. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@141084 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-04TableGen: Store all allocation orders together.Jakob Stoklund Olesen

2011-10-04TableGen: Privatize CodeGenRegisterClass::TheDef and Name.Jakob Stoklund Olesen
When TableGen starts creating its own register classes, the synthesized classes won't have a Record reference. All register classes must have a name, though. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@141081 91177308-0d34-0410-b5e6-96231b3b80d8

2011-10-01Fix disassembler handling of CRC32 which is an odd instruction that uses ↵Craig Topper
0xf2 as an opcode extension and allows the opsize prefix. This necessitated adding IC_XD_OPSIZE and IC_64BIT_XD_OPSIZE contexts. Unfortunately, this increases the size of the disassembler tables.
