Sanjoy Das fffaef16a2 [StatepointLowering] Fix bug in allocateStackSlot ... allocateStackSlot did not consider the size of the value to be spilled before deciding to re-use a spill slot. This was originally okay (since originally we'd only ever spill pointers), but it became not okay when we changed our scheme to directly spill vectors of pointers. While this change fixes the bug pointed out, it has two performance caveats: - It matches spill slot and spillee size exactly, while in theory we can spill, e.g., an 8 byte pointer into a 16 byte slot. This is slightly complicated to fix since in the stackmaps section, we report the size of the spill slot as the size of the "indirect value"; and if they're no longer equivalent, we'll have to keep track of the (indirect) value size separately from the stack slot size. - It will "spuriously run out" of reusable slots, since we now have an second check in the search loop in addition to the availablity check (e.g. you had two free scalar slots, and you first ask for a vector slot followed by a scalar slot). I'll fix this in a later commit. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@261336 91177308-0d34-0410-b5e6-96231b3b80d8		2016-02-19 17:15:22 +00:00
