Akira Hatanaka 40cd57eb5c [ARM] Fix a bug in constant island pass that was triggering an assertion. ... The assert was being triggered when the distance between a constant pool entry and its user exceeded the maximally allowed distance after thumb2 branch shortening. A padding was inserted after a thumb2 branch instruction was shrunk, which caused the user to be out of range. This is wrong as the padding should have been inserted by the layout algorithm so that the distance between two instructions doesn't grow later during thumb2 instruction optimization. This commit fixes the code in ARMConstantIslands::createNewWater to call computeBlockSize and set BasicBlock::Unalign when a branch instruction is inserted to create new water after a basic block. A non-zero Unalign causes the worst-case padding to be inserted when adjustBBOffsetsAfter is called to recompute the basic block offsets. rdar://problem/19130476 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@225467 91177308-0d34-0410-b5e6-96231b3b80d8		2015-01-08 20:44:50 +00:00
