2007-07-05Instructions with ImmutablePredicateOperand aren't really predicable since ↵Evan Cheng
their predicates are fixed at isel time. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@37899 91177308-0d34-0410-b5e6-96231b3b80d8
2007-06-26Revert the earlier change that removed the M_REMATERIALIZABLE machineDan Gohman
instruction flag, and use the flag along with a virtual member function hook for targets to override if there are instructions that are only trivially rematerializable with specific operands (i.e. constant pool loads). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@37728 91177308-0d34-0410-b5e6-96231b3b80d8
2007-06-19Replace M_REMATERIALIZIBLE and the newly-added isOtherReMaterializableLoadDan Gohman
with a general target hook to identify rematerializable instructions. Some instructions are only rematerializable with specific operands, such as loads from constant pools, while others are always rematerializable. This hook allows both to be identified as being rematerializable with the same mechanism. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@37644 91177308-0d34-0410-b5e6-96231b3b80d8

2006-06-15Instructions with variable operands (variable_ops) can have a number requiredEvan Cheng
operands. e.g. def CALL32r : I<0xFF, MRM2r, (ops GR32:$dst, variable_ops), "call {*}$dst", [(X86call GR32:$dst)]>; TableGen should emit operand informations for the "required" operands. Added a target instruction info flag M_VARIABLE_OPS to indicate the target instruction may have more operands in addition to the minimum required operands. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28791 91177308-0d34-0410-b5e6-96231b3b80d8

2005-08-19Emit this:Chris Lattner
static const TargetOperandInfo OperandInfo6[] = { { &PPC32::CRRCRegClass }, { 0 }, }; instead of this: static const TargetOperandInfo OperandInfo6[] = { { PPC32::CRRCRegisterClass }, { 0 }, }; For operand information, which does not require dynamic (startup-time) initialization. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22931 91177308-0d34-0410-b5e6-96231b3b80d8
2005-08-19Emit real operand info for instructions. This currently works but is badChris Lattner
in one way: the generated tables require dynamic initialization for the register classes. This will be fixed in a future patch. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22919 91177308-0d34-0410-b5e6-96231b3b80d8

instruction defined, actually emit this to the InstrInfoDescriptor, which allows an assert in the machineinstrbuilder to do some checking for us, and is required by the dag->dag emitter git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22895 91177308-0d34-0410-b5e6-96231b3b80d8

2005-08-18When emitting implicit use/def lists, only emit each unique list once. ThoughChris Lattner
LLVM is able to merge identical static const globals, GCC isn't, and this caused some bloat in the generated data. This has a marginal effect on PPC, shrinking the implicit sets from 10->4, but shrinks X86 from 179 to 23, a much bigger reduction. This should speed up the register allocator as well by reducing the dcache footprint for this static data. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22879 91177308-0d34-0410-b5e6-96231b3b80d8
