* Pull utility routines with no SelectionDAG dependence out ofDan Gohman2010-04-143-76/+95
| | | | | | | SelectionDAGBuilder. FunctionLoweringInfo isn't an ideal place for them to live, but it's better than SelectionDAGBuilder for now. llvm-svn: 101267

| | | | llvm-svn: 101248
* Enable RTTI again. While this works fine for LLVM, it creates an ABINick Lewycky2010-04-141-0/+1
| | | | | | incompatibility with some clients covered by the buildbots, such as llvm-gcc. llvm-svn: 101237
* Turn off RTTI for VMCore. Yay!Nick Lewycky2010-04-141-1/+0
| | | | llvm-svn: 101233
* I don't know how, but I managed to goof the revert. Remove function that shouldNick Lewycky2010-04-141-37/+0
| | | | | | have been removed in r101231. llvm-svn: 101232
* Revert r101213.Nick Lewycky2010-04-141-29/+14

| | | | | | | | | | | | | | | | | | | current PC. rdar://7834775 We now produce an identical .o file compared to the cctools assembler for something like this: _f0: L0: jmp L1 .long . - L0 L1: jmp A .long . - L1 .zerofill __DATA,_bss,A,0 llvm-svn: 101227
* Remove tab.Nick Lewycky2010-04-141-1/+1
| | | | llvm-svn: 101223
* While DAE can't modify the function signature of an externally visible function,Nick Lewycky2010-04-141-14/+66
| | | | | | | | | it can check whether the visible direct callers are passing in parameters to dead arguments and replace those with undef. This reinstates r94322 with bugs fixed. llvm-svn: 101213
* Generalize this code to handle Instructions in addition to ConstantExprs.Dan Gohman2010-04-141-3/+3
| | | | llvm-svn: 101210
* Reorder the methods of this class to be a little more organized.Dan Gohman2010-04-141-22/+22
| | | | llvm-svn: 101206
* Fixed another assert exposed by fuzzing. Now, when an encoding error occursJohnny Chen2010-04-141-4/+14
| | | | | | | involing getBFCInvMask() where lsb <= msb does not hold true, the disassembler just returns false, instead of assert, to indicate disassembly error. llvm-svn: 101205
* Clear MachineInstr->MCSymbol maps at the end of a function.Devang Patel2010-04-141-0/+2
| | | | llvm-svn: 101202
* Fixed an assert() exposed by fuzzing. Now, instead of assert when an invalidJohnny Chen2010-04-142-10/+15
| | | | | | | instruction encoding is encountered, we just return a NULL ARMBasicMCBuilder instance and the client just returns false to indicate disassembly error. llvm-svn: 101201

| | | | | | | bit (we're not trying to build a shared library yet) and generating the X86GenEDInfo.inc and ARMGenEDInfo.inc files as necessary. llvm-svn: 101188
* Fast path implicit_def check.Evan Cheng2010-04-131-5/+5
| | | | llvm-svn: 101183
* Handle a v2f64 formal parameter that is split between registers and memoryBob Wilson2010-04-131-7/+13
| | | | | | such that the entire second half is in memory. Radar 7855014. llvm-svn: 101181
* Fixed a nasty layering violation in the edis sourceSean Callanan2010-04-134-2/+30
| | | | | | | | | | | | | | | code. It used to #include the enhanced disassembly information for the targets it supported straight out of lib/Target/{X86,ARM,...} but now it uses a new interface provided by MCDisassembler, and (so far) implemented by X86 and ARM. Also removed hacky #define-controlled initialization of targets in edis. If clients only want edis to initialize a limited set of targets, they can set --enable-targets on the configure command line. llvm-svn: 101179
* Changed getSOImmValRotate()'s hunt retry logic to ignore the low order 6 bits,Johnny Chen2010-04-131-3/+3
| | | | | | instead of 7, because we are only looking for even rotate amount. llvm-svn: 101172
* Do not include types without any definition in pubtypes list.Devang Patel2010-04-131-2/+4

* Avoid variable shadowing.Evan Cheng2010-04-131-2/+2
| | | | llvm-svn: 101170
* Expand postra machine licm's capability a little more. If an instruction's ↵Evan Cheng2010-04-131-8/+24
| | | | | | register operands are all loop invariants, then it's safe to hoist it. llvm-svn: 101167
* Teach MachineSinking to handle easy critical edges.Jakob Stoklund Olesen2010-04-131-2/+17
| | | | | | | | | | | | | | Sometimes it is desirable to sink instructions along a critical edge: x = ... if (a && b) ... else use(x); The 'a && b' condition creates a critical edge to the else block, but we still want to sink the computation of x into the block. The else block is dominated by the parent block, so we are not pushing instructions into new code paths. llvm-svn: 101165
* Re-apply 101075 and fix it properly. Just reuse the debug info of the branch ↵Evan Cheng2010-04-131-1/+44
| | | | | | instruction being optimized. There is no need to --I which can deref off start of the BB. llvm-svn: 101162
* Temporarily revert r101075, it's causing invalid iterator assertionsEric Christopher2010-04-131-46/+1
| | | | | | in a nightly tester. llvm-svn: 101158
* Teach postra machine licm to hoist more obvious invariants, e.g. ↵Evan Cheng2010-04-131-17/+38
| | | | | | instructions with no source operands. llvm-svn: 101154
* Add a few comments.Dan Gohman2010-04-131-0/+5
| | | | llvm-svn: 101148
* Eliminate MachineBasicBlock::const_livein_iterator and makeDan Gohman2010-04-137-10/+11
| | | | | | | | MachineBasicBlock::livein_iterator a const_iterator, because clients shouldn't ever be using the iterator interface to mutate the livein set. llvm-svn: 101147
* Rename MachineFrameInfo variables to MFI, for consistency withDan Gohman2010-04-131-41/+41

* Move MachineRegisterInfo's isLiveIn and isLiveOut out of line.Dan Gohman2010-04-131-0/+14
