Shuxin Yang 253449db20 PR14904: Segmentation fault running pass 'Recognize loop idioms' ... The root cause is mistakenly taking for granted that "dyn_cast<Instruction>(a-Value)" return a non-NULL instruction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@172145 91177308-0d34-0410-b5e6-96231b3b80d8		2013-01-10 23:32:01 +00:00

Hello	Move all of the header files which are involved in modelling the LLVM IR	2013-01-02 11:36:10 +00:00
InstCombine	Teach InstCombine to hoist FABS and FNEG through FPTRUNC instructions. The application of these operations commutes with the truncation, so we should prefer to do them in the smallest size we can, to save register space, use smaller constant pool entries, etc.	2013-01-10 22:06:52 +00:00
Instrumentation	[msan] Change va_start/va_copy shadow memset alignment to 8.	2013-01-10 22:36:33 +00:00
IPO	Fix TryToShrinkGlobalToBoolean in GlobalOpt, so that it does not discard address spaces.	2013-01-10 10:31:11 +00:00
Scalar	PR14904: Segmentation fault running pass 'Recognize loop idioms'	2013-01-10 23:32:01 +00:00
Utils	Make sure we don't emit instructions before a landingpad instruction.	2013-01-08 10:51:32 +00:00
Vectorize	LoopVectorizer: Fix a bug in the vectorization of BinaryOperators. The BinaryOperator can be folded to an Undef, and we don't want to set NSW flags to undef vals.	2013-01-10 17:34:39 +00:00
CMakeLists.txt	Add a basic-block autovectorization pass.	2012-02-01 03:51:43 +00:00
LLVMBuild.txt	Add a basic-block autovectorization pass.	2012-02-01 03:51:43 +00:00
