* [X86] Perform VSELECT DAG combines also before DAG type legalization.Juergen Ributzka2013-09-052-12/+12
| | | | | | | | | | | | | If the DAG already has only legal types, then the second round of DAG combines is skipped. In this case VSELECT+SETCC patterns that match a more efficient instruction (e.g. min/max) are never recognized. This fix allows VSELECT+SETCC combines if the types are already legal before DAG type legalization.

* Fixed a crash in the integrated assembler for Mach-O when a symbol differenceKevin Enderby2013-09-052-0/+42
| | | | | | | | | | | | | | expression uses an assembler temporary symbol from an assignment.  In this case the symbol does not have a fragment so the use of getFragment() would be NULL and caused a crash. In the case of an assembler temporary symbol we want to use the AliasedSymbol (if any) which will create a local relocation entry, but if it is not an assembler temporary symbol then let it use that symbol with an external relocation entry. rdar://9356266 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@190096 91177308-0d34-0410-b5e6-96231b3b80d8

* Debug Info: Use identifier to reference DIType in base type field ofManman Ren2013-09-057-6/+156
| | | | | | | | | | | | | | | | | | | | | | | ptr_to_member. We introduce a new class DITypeRef that represents a reference to a DIType. It wraps around a Value*, which can be either an identifier in MDString or an actual MDNode. The class has a helper function "resolve" that finds the actual MDNode for a given DITypeRef. We specialize getFieldAs to return a field that is a reference to a DIType. To correctly access the base type field of ptr_to_member, getClassType now calls getFieldAs<DITypeRef> to return a DITypeRef. Also add a typedef for DITypeIdentifierMap and a helper generateDITypeIdentifierMap in DebugInfo.h. In DwarfDebug.cpp, we keep a DITypeIdentifierMap and call generateDITypeIdentifierMap to actually populate the map. Verifier is updated accordingly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@190081 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | This pass was segfaulting when it ran into a non-intrinsic function call.

* Add AArch32 DCPS{1,2,3} and HLT instructions.Richard Barton2013-09-0510-7/+166
| | | | | | | | | | | | | | | | | | | These were pretty straightforward instructions, with some assembly support required for HLT. The ARM assembler is keen to split the instruction mnemonic into a (non-existent) 'H' instruction with the LT condition code. An exception for HLT is needed. HLT follows the same rules as BKPT when in IT blocks, so the special BKPT hadling code has been adapted to handle HLT also. Regression tests added including diagnostic tests for out of range immediates and illegal condition codes, as well as negative tests for pre-ARMv8. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@190053 91177308-0d34-0410-b5e6-96231b3b80d8
* Reverting 190043 for now.Tilmann Scheller2013-09-054-99/+3
| | | | | | | | | Solution is not sufficient to prevent 'mov pc, lr' being emitted for jump table code. Test case doesn't trigger the added functionality. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@190047 91177308-0d34-0410-b5e6-96231b3b80d8
* ARM: Add GPR register class excluding LR for use with the ADR instruction.Tilmann Scheller2013-09-054-3/+99
| | | | | | | | | | This improves code generation for jump tables by avoiding the emission of "mov pc, lr" which could fool the processor into believing this is a return from a function causing mispredicts. The code generation logic for jump tables uses ADR to materialize the address of the jump target.

* [Sparc] Correctly handle call to functions with ReturnsTwice attribute.Venkatraman Govindaraju2013-09-055-4/+116
| | | | | | | | | | | | | | In sparc, setjmp stores only the registers %fp, %sp, %i7 and %o7. longjmp restores the stack, and the callee-saved registers (all local/in registers: %i0-%i7, %l0-%l7) using the stored %fp and register windows. However, this does not guarantee that the longjmp will restore the registers, as they were when the setjmp was called. This is because these registers may be clobbered after returning from setjmp, but before calling longjmp. This patch prevents the registers %i0-%i5, %l0-l7 to live across the setjmp call using the register mask. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@190033 91177308-0d34-0410-b5e6-96231b3b80d8
