reduce size of static tables. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@152524 91177308-0d34-0410-b5e6-96231b3b80d8

2012-03-08Re-commit r152202 hopefully fixing the MSVC linker error.Craig Topper
Original commit message: Use uint16_t to store InstrNameIndices in MCInstrInfo. Add asserts to protect all 16-bit string table offsets. Also make sure the string to offset table string is not larger than 65536 characters since larger string literals aren't portable. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@152296 91177308-0d34-0410-b5e6-96231b3b80d8

2012-03-06Increase number of allowed registers in register classes to 64k instead of ↵Craig Topper
256. Widen register class ID to 16-bits. Widen register size and alignment to be up to 64k bytes instead of 256 bytes. This partially reverts r152019 to be less restrictive. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@152100 91177308-0d34-0410-b5e6-96231b3b80d8
2012-03-06Revert r152016 and allow overlap, sub, super register tables to be more than ↵Craig Topper

2012-03-05ARM refactor away a bunch of VLD/VST pseudo instructions.Jim Grosbach
With the new composite physical registers to represent arbitrary pairs of DPR registers, we don't need the pseudo-registers anymore. Get rid of a bunch of them that use DPR register pairs and just use the real instructions directly instead. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@152045 91177308-0d34-0410-b5e6-96231b3b80d8

2012-03-04Use uint16_t instead of unsigned to store registers in reg classes. Reduces ↵Craig Topper
static data size. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@151998 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@151821 91177308-0d34-0410-b5e6-96231b3b80d8
2012-03-01Move TargetRegisterInfo::getSubReg() to MCRegisterInfo.Jim Grosbach
Allows us to de-virtualize the function and provides access to it in the instruction printer, which is useful for handling composite physical registers (e.g., ARM register lists). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@151815 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-28On ELF, create relocations to the abbreviation and line sections when producingRafael Espindola
debug info for assembly files. We were already doing the right thing when producing debug info for C/C++. ELF linkers don't know dwarf, so they depend on these relocations to produce valid dwarf output. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@151655 91177308-0d34-0410-b5e6-96231b3b80d8
2012-02-27ARM BL/BLX instruction fixups should use relocations.Jim Grosbach
We on the linker to resolve calls to the appropriate BL/BLX instruction to make interworking function correctly. It uses the symbol in the relocation to do that, so we need to be careful about being too clever. To enable this for ARM mode, split the BL/BLX fixup kind off from the unconditional-branch fixups. rdar://10927209 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@151571 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@151043 91177308-0d34-0410-b5e6-96231b3b80d8
2012-02-21In generated RegisterInfo files, replace a pointer to the end of an array ↵Craig Topper
with just the size of the array to avoid relocations. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@151041 91177308-0d34-0410-b5e6-96231b3b80d8
2012-02-21Merge some tables in generated RegisterInfo file. Store indices into larger ↵Craig Topper
table instead of pointers to reduce relocations and shrink table size on 64-bit builds. Shaves ~24K off X86MCTargetDesc.o git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@151038 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-17Don't lazily allocate eh_frame. We're not lazily allocating things like the ↵David Chisnall
LSDA, which are only used when the eh frame is used, so this lazy allocation doesn't really make sense. Fix the type of eh_frame on Solaris so that Sun ld doesn't fail to combine them (thus making it impossible for the unwind library to find them and breaking exceptions). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@150814 91177308-0d34-0410-b5e6-96231b3b80d8

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
2012-02-09Move the Name field in MCInstrDesc to the end, saving 8 bytes of padding per ↵Benjamin Kramer
entry on x86_64. No change on i386. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@150170 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-06Enable streaming of bitcodeDerek Schuff
This CL delays reading of function bodies from initial parse until materialization, allowing overlap of compilation with bitcode download. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@149918 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-03Add a new MachineJumpTableInfo entry type, EK_GPRel64BlockAddress, which isAkira Hatanaka
needed to emit a 64-bit gp-relative relocation entry. Make changes necessary for emitting jump tables which have entries with directive .gpdword. This patch does not implement the parts needed for direct object emission or JIT. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@149668 91177308-0d34-0410-b5e6-96231b3b80d8

2012-01-26Add support for the R_ARM_TARGET1 relocation, which should be given to ↵James Molloy
relocations applied to all C++ constructors and destructors. This enables the linker to match concrete relocation types (absolute or relative) with whatever library or C++ support code is being linked against. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@149057 91177308-0d34-0410-b5e6-96231b3b80d8

2012-01-24Revert r148686 (and r148694, a fix to it) due to a serious layeringChandler Carruth
violation -- MC cannot depend on CodeGen. Specifically, the MCTargetDesc component of each target is actually a subcomponent of the MC library. As such, it cannot depend on the target-independent code generator, because MC itself cannot depend on the target-independent code generator. This change moved a flag from the ARM MCTargetDesc file ARMMCAsmInfo.cpp to the CodeGen layer in ARMException.cpp, leaving behind an 'extern' to refer back to it. That layering order isn't viable givin the constraints outlined above. Commandline flags are designed to be static specifically to avoid these types of bugs. Fixing this is likely going to require some non-trivial refactoring. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@148759 91177308-0d34-0410-b5e6-96231b3b80d8

2012-01-23An option to selectively enable parts of ARM EHABI support.Evgeniy Stepanov
This change adds an new value to the --arm-enable-ehabi option that disables emitting unwinding descriptors. This mode gives a working backtrace() without the (currently broken) exception support. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@148686 91177308-0d34-0410-b5e6-96231b3b80d8
2012-01-19Add a new form of MCOperand, for representing sub-instructions. This is ↵Owen Anderson
intended for supporting bundles through the MC layer, rather than lowering them pre-MC as we currently do for Thumb2 IT blocks. Since these sub-instruction operands hold pointers to the sub-instructions, it is the responsibility of the target's AsmPrinter to provide storage for them for the duration of the EmitInstruction() call. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@148492 91177308-0d34-0410-b5e6-96231b3b80d8
