2012-02-10Put instruction names into an indexed string table on the side, removing a ↵Benjamin Kramer
pointer from MCInstrDesc. Make them accessible through MCInstrInfo. They are only used for debugging purposes so this doesn't have an impact on performance. X86MCTargetDesc.o goes from 630K to 461K on x86_64. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@150245 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-03Increment DFAStateEntryTable index for sentinel entry.Brendon Cahoon
When adding the {-1, -1} entry to the DFAStateInputTable, we need to increment the index used to populate the DFAStateEntryTable. Otherwise, the entry table will be off by one for each transition after the {-1, -1} entry. PR11908. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@149713 91177308-0d34-0410-b5e6-96231b3b80d8
2012-02-01Specify SubRegIndex components on the index itself.Jakob Stoklund Olesen
It is simpler to define a composite index directly: def ssub_2 : SubRegIndex<[dsub_1, ssub_0]>; def ssub_3 : SubRegIndex<[dsub_1, ssub_1]>; Than specifying the composite indices on each register: CompositeIndices = [(ssub_2 dsub_1, ssub_0), (ssub_3 dsub_1, ssub_1)] in ... This also makes it clear that SubRegIndex composition is supposed to be unique. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@149556 91177308-0d34-0410-b5e6-96231b3b80d8
2012-02-01Fix a bug in the TopoOrderRC comparison function.Jakob Stoklund Olesen
The final tie breaker comparison also needs to return +/-1, or 0. This is not a less() function. This could cause otherwise identical super-classes to be ordered unstably, depending on what the system qsort routine does with a bad compare function. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@149549 91177308-0d34-0410-b5e6-96231b3b80d8
2012-02-01Avoid emitting empty arrays, they're not standard C++.Jakob Stoklund Olesen
It's only by luck that we haven't produced any yet, and clang refuses to compile them. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@149546 91177308-0d34-0410-b5e6-96231b3b80d8

2012-01-31Add a TableGen CodeGenSubRegIndex class.Jakob Stoklund Olesen
This class is used to represent SubRegIndex instances instead of the raw Record pointers that were used before. No functional change intended. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@149418 91177308-0d34-0410-b5e6-96231b3b80d8

2012-01-18Add a CoveredBySubRegs property to Register descriptions.Jakob Stoklund Olesen
When set, this bit indicates that a register is completely defined by the value of its sub-registers. Use the CoveredBySubRegs property to infer which super-registers are call-preserved given a list of callee-saved registers. For example, the ARM registers D8-D15 are callee-saved. This now automatically implies that Q4-Q7 are call-preserved. Conversely, Win64 callees save XMM6-XMM15, but the corresponding YMM6-YMM15 registers are not call-preserved because they are not fully defined by their sub-registers. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@148363 91177308-0d34-0410-b5e6-96231b3b80d8
2012-01-17Add TableGen support for callee saved registers.Jakob Stoklund Olesen
Targets can now add CalleeSavedRegs defs to their *CallingConv.td file. TableGen will use this to create a *_SaveList array suitable for returning from getCalleeSavedRegs() as well as a *_RegMask bit mask suitable for returning from getCallPreservedMask(). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@148346 91177308-0d34-0410-b5e6-96231b3b80d8

2012-01-16Removing unused default switch cases in switches over enums that already ↵David Blaikie
account for all enumeration values explicitly. (This time I believe I've checked all the -Wreturn-type warnings from GCC & added the couple of llvm_unreachables necessary to silence them. If I've missed any, I'll happily fix them as soon as I know about them) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@148262 91177308-0d34-0410-b5e6-96231b3b80d8

2012-01-13Delete CodeInit and CodeRecTy from TableGen.Jakob Stoklund Olesen
The code type was always identical to a string anyway. Now it is simply a synonym. The code literal syntax [{...}] is still valid. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@148092 91177308-0d34-0410-b5e6-96231b3b80d8

2012-01-07Fix TableGen so that it will emit the correct signature for FastEmit_f:Cameron Zwarich
/// FastEmit_f - This method is called by target-independent code /// to request that an instruction with the given type, opcode, and /// floating-point immediate operand be emitted. virtual unsigned FastEmit_f(MVT VT, MVT RetVT, unsigned Opcode, const ConstantFP *FPImm); Currently, it emits an accidentally overloaded version without the const on the ConstantFP*. This doesn't affect anything in the tree, since nothing causes that method to be autogenerated, but I have been playing with some ARM TableGen refactorings that hit this problem. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@147727 91177308-0d34-0410-b5e6-96231b3b80d8

2011-12-19Emit a getMatchingSuperRegClass() implementation for every target.Jakob Stoklund Olesen
Use information computed while inferring new register classes to emit accurate, table-driven implementations of getMatchingSuperRegClass(). Delete the old manual, error-prone implementations in the targets. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@146873 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-19Synthesize register classes for TRI::getMatchingSuperRegClass().Jakob Stoklund Olesen
Teach TableGen to create the missing register classes needed for getMatchingSuperRegClass() to return maximal results. The function is still not auto-generated, so it still returns inexact results. This produces these new register classes: ARM: QQPR_with_dsub_0_in_DPR_8 QQQQPR_with_dsub_0_in_DPR_8 X86: GR64_with_sub_32bit_in_GR32_NOAX GR64_with_sub_32bit_in_GR32_NOAX_and_GR32_NOSP GR64_with_sub_16bit_in_GR16_NOREX GR64_with_sub_32bit_in_GR32_NOAX_and_GR32_NOREX GR64_TC_and_GR64_with_sub_32bit_in_GR32_NOAX GR64_with_sub_32bit_in_GR32_NOAX_and_GR32_NOREX_NOSP GR64_TCW64_and_GR64_with_sub_32bit_in_GR32_NOAX GR64_TC_and_GR64_with_sub_32bit_in_GR32_NOAX_and_GR32_NOREX GR64_with_sub_32bit_in_GR32_TC GR64_with_sub_32bit_in_GR32_ABCD_and_GR32_NOAX GR64_with_sub_32bit_in_GR32_NOAX_and_GR32_TC GR64_with_sub_32bit_in_GR32_AD GR64_with_sub_32bit_in_GR32_AD_and_GR32_NOAX The other targets in the tree are not weird enough to be affected. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@146872 91177308-0d34-0410-b5e6-96231b3b80d8
