* Additional fix for PR1422: make sure the landing pad label is placed in theDuncan Sands2007-06-061-15/+26
| | | | | | | correct machine basic block - do not rely on the eh.exception intrinsic being in the landing pad: the loop optimizers can move it out. llvm-svn: 37463
* Integrate exception filter support and exception catch support. ThisDuncan Sands2007-06-021-3/+4
| | | | | | | | simplifies the code in DwarfWriter, allows for multiple filters and makes it trivial to specify filters accompanied by cleanups or catch-all specifications (see next patch). What a deal! Patch blessed by Anton. llvm-svn: 37398
* Since TypeInfos are passed as i8 pointers, a NULL TypeInfo should be passedDuncan Sands2007-06-011-4/+2
| | | | | | as a null i8 pointer not as a 0 i32. llvm-svn: 37383
* Minor comment cleanups.Dan Gohman2007-05-241-1/+1
| | | | llvm-svn: 37321
* Mark all calls as "could throw", when exceptions are enabled. Emit necessary ↵Anton Korobeynikov2007-05-231-33/+38
| | | | | | LP info too. This fixes PR1439 llvm-svn: 37311
* Qualify several calls to functions in the MVT namespace, for consistency.Dan Gohman2007-05-181-7/+7
| | | | llvm-svn: 37230
* Fix some subtle issues handling immediate values. This fixesChris Lattner2007-05-151-3/+6
| | | | | | test/CodeGen/ARM/2007-05-14-InlineAsmCstCrash.ll llvm-svn: 37069
* Do not assert, when case range split metric is zero and JTs are not allowed: ↵Anton Korobeynikov2007-05-091-5/+12
| | | | | | | | just emit binary tree in this case. This fixes PR1403. llvm-svn: 36959
* Parameter attributes on invoke calls were being lost due to the wrongDuncan Sands2007-05-071-4/+6
| | | | | | | attribute index being used. Fix proposed by Anton Korobeynikov, who asked me to implement and commit it for him. This is PR1398. llvm-svn: 36906
* DetabifyAnton Korobeynikov2007-05-061-1/+1
| | | | llvm-svn: 36891
* A bitcast of a global variable may have been constant folded to a GEP -Duncan Sands2007-05-041-26/+30
| | | | | | handle this case too. llvm-svn: 36745
* Drop 'const'Devang Patel2007-05-031-1/+1

* Properly set arguments bitwidth of EHSELECT nodeAnton Korobeynikov2007-05-021-2/+2
| | | | llvm-svn: 36654
* Use 'static const char' instead of 'static const int'.Devang Patel2007-05-021-1/+1
| | | | | | | Due to darwin gcc bug, one version of darwin linker coalesces static const int, which defauts PassID based pass identification. llvm-svn: 36652
* Do not use typeinfo to identify pass in pass manager.Devang Patel2007-05-011-0/+2
| | | | llvm-svn: 36632
* Continue refactoring inline asm code. If there is an earlyclobber outputChris Lattner2007-04-301-79/+108
| | | | | | | | register, preallocate all input registers and the early clobbered output. This fixes PR1357 and CodeGen/PowerPC/2007-04-30-InlineAsmEarlyClobber.ll llvm-svn: 36599
* refactor GetRegistersForValue to take OpInfo as an argument instead of variousChris Lattner2007-04-301-98/+101

* refactor some code, no functionality changeChris Lattner2007-04-301-44/+52

* memory operands that have a direct operand should have their stores createdChris Lattner2007-04-281-35/+42
| | | | | | | | | | | | | before the copies into physregs are done. This avoids having flag operands skip the store, causing cycles in the dag at sched time.

* memory inputs to an inline asm are required to have an address available.Chris Lattner2007-04-281-18/+32
| | | | | | | | | If the operand is not already an indirect operand, spill it to a constant pool entry or a stack slot. This fixes PR1356 and CodeGen/X86/2007-04-27-InlineAsm-IntMemInput.ll llvm-svn: 36536

* the result of an inline asm copy can be an arbitrary VT that the registerChris Lattner2007-04-121-4/+21
| | | | | | | | class supports. In the case of vectors, this means we often get the wrong type (e.g. we get v4f32 instead of v8i16). Make sure to convert the vector result to the right type. This fixes CodeGen/X86/2007-04-11-InlineAsmVectorResult.ll llvm-svn: 35944
