* Preserve ProfileInfo.Andreas Neustifter2009-09-091-1/+9
| | | | llvm-svn: 81360
* When widening a vector load, use the correct chain. This fixes PR4891.Dan Gohman2009-09-091-1/+1
| | | | llvm-svn: 81343
* change selectiondag to add the sign extended versions of immediate operandsChris Lattner2009-09-081-1/+1
| | | | | | | | to instructions instead of zero extended ones. This makes the asmprinter print signed values more consistently. This apparently only really affects the X86 backend. llvm-svn: 81265
* When emitting a label for a PostCall safe point, the machineNicolas Geoffray2009-09-081-6/+11
| | | | | | | | instruction to insert before can be end(). getDebugLoc on end() returns an invalid value, therefore use the debug loc of the call instruction, and give it to InsertLabel. llvm-svn: 81207
* When remat'ing and destination virtual register has a sub-register index. ↵Evan Cheng2009-09-081-0/+16
| | | | | | Make sure the sub-register class matches the register class of the remat'ed instruction definition register class. llvm-svn: 81204
* Fix an abort on a store of an empty struct member. getValue returnsDan Gohman2009-09-081-0/+4
| | | | | | | null in the case of an empty struct, so don't try to call getNumValues on it. llvm-svn: 81180
* Fix a thinko: When lowering fneg with xor, bitcast the operandsDan Gohman2009-09-071-4/+17
| | | | | | | | | from floating-point to integer first, and bitcast the result back to floating-point. Previously, this test was passing by falling back to SelectionDAG lowering. The resulting code isn't as nice, but it's correct and CodeGen now stays on the fast path. llvm-svn: 81171
* Simplify. Testing shows that this is not equivalent to BBI = CR.CaseBB + 1.Duncan Sands2009-09-061-4/+2

* Mark more constants unsigned, as warned about by icc (#68).Duncan Sands2009-09-061-1/+1
| | | | | | Patch by Erick Tryzelaar. llvm-svn: 81116
* Remove some not-really-used variables, as warnedDuncan Sands2009-09-064-14/+2
| | | | | | about by icc (#593, partial). Patch by Erick Tryzelaar. llvm-svn: 81115
* It's a bool, so treat it like one. Fixes a MSVC warning.Benjamin Kramer2009-09-061-4/+4

* Remove some unused variables and methods warned about byDuncan Sands2009-09-062-5/+1
| | | | | | icc (#177, partial). Patch by Erick Tryzelaar. llvm-svn: 81106
* Detect VLAs.Devang Patel2009-09-051-1/+5
| | | | | | Do not use DenseMap operator[] because it inserts new entry if lookup fails. Use find() to check an entry in a DenseMap first. llvm-svn: 81058
* Ignore malformed global variable debug info.Devang Patel2009-09-041-0/+4
| | | | llvm-svn: 81055
* Replaces uses of unsigned for indexes in LiveInterval and VNInfo withLang Hames2009-09-0410-447/+517
| | | | | | | | a new class, MachineInstrIndex, which hides arithmetic details from most clients. This is a step towards allowing the register allocator to update/insert code during allocation. llvm-svn: 81040
* Use delete[] to match new[] (found by valgrind).Duncan Sands2009-09-041-1/+1
| | | | llvm-svn: 80997

| | | | llvm-svn: 80976
* Funky indentation.Evan Cheng2009-09-031-1/+2
| | | | llvm-svn: 80971
* LLVM currently represents floating-point negation as -0.0 - x. FixDan Gohman2009-09-031-0/+23
| | | | | | | FastISel to recognize this pattern and emit a floating-point negation using xor. llvm-svn: 80963

* Overhaul the TwoAddressInstructionPass to simplify the logic, especiallyBob Wilson2009-09-031-159/+210
| | | | | | | | | | | | | | | | | for the complicated case where one register is tied to multiple destinations. This avoids the extra scan of instruction operands that was introduced by my recent change. I also pulled some code out into a separate TryInstructionTransform method, added more comments, and renamed some variables. Besides all those changes, this takes care of a FIXME in the code regarding an assumption about there being a single tied use of a register when converting to a 3-address form. I'm not aware of cases where that assumption is violated, but the code now only attempts to transform an instruction, either by commuting its operands or by converting to a 3-address form, for the simple case where there is a single pair of tied operands. llvm-svn: 80945
* Recognize more opportunities to use SSE min and max instructions,Dan Gohman2009-09-031-0/+13

* Fixed a test that ensures the LocalRewriter does not attempt toLang Hames2009-09-032-2/+2
| | | | | | | | | avoid reloads by reusing clobbered registers. This was causing issues in 256.bzip2 when compiled with PIC for a while (starting at r78217), though the problem has since been masked. llvm-svn: 80872
* Rearrange code to eliminate redundancy and avoid gotos.Bob Wilson2009-09-021-64/+40
| | | | llvm-svn: 80798
* Retype from unsigned to CallingConv::ID accordingly. Approved by Bob Wilson.Sandeep Patel2009-09-022-3/+4
| | | | llvm-svn: 80773
* Avoid calling removeVirtualRegisterKilled which iterates over the operandsBob Wilson2009-09-011-1/+2

* Refactor some code into separate functions. No functional changes.Bob Wilson2009-09-011-52/+82

* Fix pr4843: When an instruction has multiple destination registers that areBob Wilson2009-09-011-11/+55
| | | | | | | | | tied to different source registers, the TwoAddressInstructionPass needs to be smarter. Change it to check before replacing a source register whether that source register is tied to a different destination register, and if so, defer handling it until a subsequent iteration. llvm-svn: 80654
* Clean up LSDA name generation and use for SJLJ exception handling. ThisJim Grosbach2009-09-013-12/+25
| | | | | | | | | | | makes an eggregious hack somewhat more palatable. Bringing the LSDA forward and making it a GV available for reference would be even better, but is beyond the scope of what I'm looking to solve at this point. Objective C++ code could generate function names that broke the previous scheme. This fixes that. llvm-svn: 80649

* PR4747Jim Grosbach2009-08-312-36/+23
| | | | | | | | | | | | | Shared landing pads run into trouble with SJLJ, as the dispatch table is mapped to call sites, and merging the pads will throw that off. There needs to be a one-to-one mapping of landing pad exception table entries to invoke call points. Detecting the shared pad during lowering of SJLJ info insn't sufficient, as the dispatch function may still need separate destinations to properly handle phi-nodes. llvm-svn: 80530
