* The VPERM2F128 is a AVX instruction which permutes between two 256-bitBruno Cardoso Lopes2011-08-127-0/+132

* Initial commit of the 'landingpad' instruction.Bill Wendling2011-08-1215-10/+303
| | | | | | | | | | | | This implements the 'landingpad' instruction. It's used to indicate that a basic block is a landing pad. There are several restrictions on its use (see LangRef.html for more detail). These restrictions allow the exception handling code to gather the information it needs in a much more sane way. This patch has the definition, implementation, C interface, parsing, and bitcode support in it. llvm-svn: 137501

It is not valid to interpret the value of a floating pointer register as part of a double precision floating point value after a single precision floating point computational or move instruction stores its result to the register. - In the test case, the following code is generated before this patch is applied: mtc1 $zero, $f2 ; unformatted copy to $f2 mov.s $f0, $f2 ; $f0 is in single format sdc1 $f12, 0($sp) mov.s $f1, $f2 ; $f1 is in single format c.eq.d $f12, $f0 ; $f0 cannot be interpreted as double - The following code is generated after this patch is applied: mtc1 $zero, $f0 ; unformatted copy to $f0 mtc1 $zero, $f1 ; unformatted copy to $f1 c.eq.d $f12, $f0 ; $f0 can be interpreted as double Bhanu Chetlapalli and Chris Dearman at MIPS technologies reported this bug and provided the test case. llvm-svn: 137484

* MachOWriter: Don't crash on fixups with arithmetic, emit a relocation ↵Benjamin Kramer2011-08-121-2/+6

* findDeadCallerSavedReg fix: Missing NULL terminator in register arrays.Andrew Trick2011-08-121-2/+2
| | | | | | Fix by Ivan Baev. Sorry I don't have a unit test, but the fix is obvious so I don't want to delay it. llvm-svn: 137404
* Don't convert objc_autoreleaseReturnValue to objc_autorelease if the resultDan Gohman2011-08-121-6/+13

* Don't let arbitrary calls disrupt nested retain+release pairs ifDan Gohman2011-08-121-56/+78
| | | | | | | | | the retains and releases all use the same SSA pointer value. Also, don't let CFG hazards disrupt nested retain+release pair optimizations. llvm-svn: 137399
* Use an actual reverse-CFG reverse-postorder for the bottom-up traversal,Dan Gohman2011-08-121-16/+30
| | | | | | | rather than plain postorder, so that CFG constructs like single-exit loops are reliably visited in a sensible order. llvm-svn: 137398
* Simplify the interference checking code a bit.Jakob Stoklund Olesen2011-08-122-112/+42
| | | | | | | This is possible now that we now longer provide an interface to iterate the interference overlaps. llvm-svn: 137397

* Allow loop unrolling to get known trip counts from ScalarEvolution.Andrew Trick2011-08-112-7/+80
| | | | | | | | | | | | | SCEV unrolling can unroll loops with arbitrary induction variables. It is a prerequisite for -disable-iv-rewrite performance. It is also easily handles loops of arbitrary structure including multiple exits and is generally more robust. This is under a temporary option to avoid affecting default behavior for the next couple of weeks. It is needed so that I can checkin unit tests for updateUnloop. llvm-svn: 137384

* Eliminate the last use of InterferenceResult.Jakob Stoklund Olesen2011-08-112-63/+57
| | | | | | | | The Query class now holds two iterators instead of an InterferenceResult instance. The iterators are used as bookmarks for repeated collectInterferingVRegs calls. llvm-svn: 137380
