* DebugInfo: PR14728: TLS supportDavid Blaikie2013-06-28
| | | | | | | | | | | | | | Based on GCC's output for TLS variables (OP_constNu, x@dtpoff, OP_lo_user), this implements debug info support for TLS in ELF. Verified that this output is correct/sufficient on Linux (using gold - if you're using binutils-ld, you'll need something with the fix for http://sourceware.org/bugzilla/show_bug.cgi?id=15685 in it). Support on non-ELF is sort of "arbitrary" at the moment - if Apple folks want to discuss (or just go ahead & implement) how this should work in MachO, etc, I'm open. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@185203 91177308-0d34-0410-b5e6-96231b3b80d8

* Add a division operator to BlockFrequency.Jakob Stoklund Olesen2013-06-28
| | | | | | | | | | | Allow a BlockFrequency to be divided by a non-zero BranchProbability with saturating arithmetic.

Looks like both the ppc-64 and mips bots are still failing after I reverted this change. Since: 1. The mips bot always performs a clean build, 2. The ppc64-bot failed again after a clean build (I asked the ppc-64 maintainers to clean the bot which they did... Thanks Will!), I think it is safe to assume that this change was not the cause of the failures that said builders were seeing. Thus I am recomitting. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@185111 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | but allowed you to arbitrarily set the category of the float. The category which an APFloat belongs to should be dependent on the actual value that the APFloat has, not be arbitrarily passed in by the user. This will prevent inconsistency bugs where the category and the actual value in APFloat differ. I also fixed up all of the references to this constructor (which were only in LLVM). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@185095 91177308-0d34-0410-b5e6-96231b3b80d8
* Improve the compression of the tablegen DiffLists by introducing a new sortChad Rosier2013-06-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | algorithm when assigning EnumValues to the synthesized registers. The current algorithm, LessRecord, uses the StringRef compare_numeric function. This function compares strings, while handling embedded numbers. For example, the R600 backend registers are sorted as follows: T1 T1_W T1_X T1_XYZW T1_Y T1_Z T2 T2_W T2_X T2_XYZW T2_Y T2_Z In this example, the 'scaling factor' is dEnum/dN = 6 because T0, T1, T2 have an EnumValue offset of 6 from one another. However, in other parts of the register bank, the scaling factors are different: dEnum/dN = 5: KC0_128_W KC0_128_X KC0_128_XYZW KC0_128_Y KC0_128_Z KC0_129_W KC0_129_X KC0_129_XYZW KC0_129_Y KC0_129_Z The diff lists do not work correctly because different kinds of registers have different 'scaling factors'. This new algorithm, LessRecordRegister, tries to enforce a scaling factor of 1. For example, the registers are now sorted as follows: T1 T2 T3 ... T0_W T1_W T2_W ... T0_X T1_X T2_X ... KC0_128_W KC0_129_W KC0_130_W ... For the Mips and R600 I see a 19% and 6% reduction in size, respectively. I did see a few small regressions, but the differences were on the order of a few bytes (e.g., AArch64 was 16 bytes). I suspect there will be even greater wins for targets with larger register files.

* TableGen: Generate a function for getting operand indices based on their ↵Tom Stellard2013-06-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | defined names This patch modifies TableGen to generate a function in ${TARGET}GenInstrInfo.inc called getNamedOperandIdx(), which can be used to look up indices for operands based on their names. In order to activate this feature for an instruction, you must set the UseNamedOperandTable bit. For example, if you have an instruction like: def ADD : TargetInstr <(outs GPR:$dst), (ins GPR:$src0, GPR:$src1)>; You can look up the operand indices using the new function, like this: Target::getNamedOperandIdx(Target::ADD, Target::OpName::dst) => 0 Target::getNamedOperandIdx(Target::ADD, Target::OpName::src0) => 1 Target::getNamedOperandIdx(Target::ADD, Target::OpName::src1) => 2 The operand names are case sensitive, so $dst and $DST are considered different operands. This change is useful for R600 which has instructions with a large number of operands, many of which model single bit instruction configuration values. These configuration bits are common across most instructions, but may have a different operand index depending on the instruction type. It is useful to have a convenient way to look up the operand indices, so these bits can be generically set on any instruction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184879 91177308-0d34-0410-b5e6-96231b3b80d8
