* Enable generating PPC pre-increment (r+imm) instructions by default.Hal Finkel2012-06-043-8/+6
| | | | | | | It seems that this no longer causes test suite failures on PPC64 (after r157159), and often gives a performance benefit, so it can be enabled by default. llvm-svn: 157911

* Use access(2) instead of stat(2) to check if a file exists.Benjamin Kramer2012-06-021-2/+1
| | | | | | | | | | | Apart from being slightly cheaper, this fixes a real bug that hits 32 bit linux systems. When passing a file larger than 2G to be linked (which isn't that uncommon with large projects such as WebKit), clang's driver checks if the file exists but the file size doesn't fit in an off_t and stat(2) fails with EOVERFLOW. Clang then says that the file doesn't exist instead of passing it to the linker. llvm-svn: 157891
* Added unittests for IntegersSubset and IntegersSubsetMapping.Stepan Dyatkovskiy2012-06-023-20/+223
| | | | | | | | | | - Fixed IntegersSubsetGeneric copy/assignment behaviour. - Fixed IntegersSubsetGeneric::getSize/getSingleValue methods. - Fixed IntegersSubsetGeneric::verify method. Also IntegersSubset.h and IntegersSubsetMapping.h headers was fixed. llvm-svn: 157887

* PR1255: case ranges.Stepan Dyatkovskiy2012-06-029-52/+57
| | | | | | IntRange converted from struct to class. So main change everywhere is replacement of ".Low/High" with ".getLow/getHigh()" llvm-svn: 157884

* PR1255: case ranges.Stepan Dyatkovskiy2012-06-023-38/+41
| | | | | | IntegersSubsetGeneric, IntegersSubsetMapping: added IntTy template parameter, that allows use either APInt or IntItem. This change allows to write unittest for these classes. llvm-svn: 157880

* Fix a bug in the code which custom-lowers truncating stores in LegalizeDAG.Akira Hatanaka2012-06-021-2/+3
| | | | | | | Check that the SDValue TargetLowering::LowerOperation returns is not null before replacing the original node with the returned node. llvm-svn: 157873

* Set operation actions for load/store nodes in the Mips backend.Akira Hatanaka2012-06-021-0/+11

* Expand unaligned i16 loads/stores for the Mips backend.Akira Hatanaka2012-06-021-1/+0
| | | | | | | | This is the first of a series of patches which make changes to the backend to emit unaligned load/store instructions (lwl,lwr,swl,swr) during instruction selection. llvm-svn: 157862
* In MipsMCInstLower::LowerSymbolOperand, get offset from symbol ifAkira Hatanaka2012-06-021-2/+4
| | | | | | the MachineOperand type has a valid offset. llvm-svn: 157861
* Remove the old register list functions from MCRegisterInfo.Jakob Stoklund Olesen2012-06-012-39/+3
| | | | | | | | | | These functions exposed the layout of the underlying data tables as null-terminated uint16_t arrays. Use the new MCSubRegIterator, MCSuperRegIterator, and MCRegAliasIterator classes instead. llvm-svn: 157855
* Switch all register list clients to the new MC*Iterator interface.Jakob Stoklund Olesen2012-06-0135-221/+199
| | | | | | | | | | | | | No functional change intended. Sorry for the churn. The iterator classes are supposed to help avoid giant commits like this one in the future. The TableGen-produced register lists are getting quite large, and it may be necessary to change the table representation. This makes it possible to do so without changing all clients (again). llvm-svn: 157854
* Register the gcov "writeout" at init time. Don't list this as a d'tor. Instead,Bill Wendling2012-06-011-2/+22
| | | | | | | | | | | | inject some code in that will run via the "__mod_init_func" method that registers the gcov "writeout" function to execute at exit time. The problem is that the "__mod_term_func" method of specifying d'tors is deprecated on Darwin. And it can lead to some ambiguities when dealing with multiple libraries. <rdar://problem/11110106> llvm-svn: 157852
* Remove physreg support from adjustCopiesBackFrom and removeCopyByCommutingDef.Jakob Stoklund Olesen2012-06-011-29/+3
| | | | | | | After physreg coalescing was disabled, these functions can't do anything useful with physregs anyway. llvm-svn: 157849
* Simplify some more getAliasSet callers.Jakob Stoklund Olesen2012-06-013-27/+15
| | | | | | MCRegAliasIterator can include Reg itself in the list. llvm-svn: 157848
* Use dominates(Instruction, Use) in the verifier.Rafael Espindola2012-06-012-48/+4
| | | | | | | This removes a bit of context from the verifier erros, but reduces code duplication in a fairly critical part of LLVM and makes dominates easier to test. llvm-svn: 157845
* [arm-fast-isel] Fix handling of the frameaddress intrinsic. If depth is 0Chad Rosier2012-06-011-1/+1
| | | | | | then DestReg is undefined. llvm-svn: 157840
* Switch some getAliasSet clients to MCRegAliasIterator.Jakob Stoklund Olesen2012-06-018-99/+46
| | | | | | | MCRegAliasIterator can optionally visit the register itself, allowing for simpler code. llvm-svn: 157837
* X86: peephole optimization to remove cmp instructionManman Ren2012-06-014-0/+350
| | | | | | | | | | | | | | | This patch will optimize the following: sub r1, r3 cmp r3, r1 or cmp r1, r3 bge L1 TO sub r1, r3 bge L1 or ble L1 If the branch instruction can use flag from "sub", then we can eliminate the "cmp" instruction. llvm-svn: 157831
* ARM: properly handle alignment for struct byval.Manman Ren2012-06-015-250/+308
| | | | | | | | | Factor out the expansion code into a function. This change is to be enabled in clang. rdar://9877866 llvm-svn: 157830
* Add some tests checking that the verifier rejects cases where a definitionRafael Espindola2012-06-011-0/+57
| | | | | | doesn't dominate a use. llvm-svn: 157829
* Provide move semantics for (Small)BitVector.Benjamin Kramer2012-06-012-0/+40
| | | | | | CodeGen makes a lot of BitVector copies. llvm-svn: 157826

* Implement the local-dynamic TLS model for x86 (PR3985)Hans Wennborg2012-06-0113-17/+353
| | | | | | | | | This implements codegen support for accesses to thread-local variables using the local-dynamic model, and adds a clean-up pass so that the base address for the TLS block can be re-used between local-dynamic access on an execution path. llvm-svn: 157818
* PR1255: case ranges.Stepan Dyatkovskiy2012-06-013-117/+141
| | | | | | | IntegersSubset devided into IntegersSubsetGeneric and into IntegersSubset itself. The first has no references to ConstantInt and works with IntItem only. IntegersSubsetMapping also made generic. Here added second template parameter "IntegersSubsetTy" that allows to use on of two IntegersSubset types described below. llvm-svn: 157815
* Remove noisy semicolons.Benjamin Kramer2012-06-011-26/+26
