2009-10-21Make changes to rev 84292 as requested by Chris Lattner.Victor Hernandez
Most changes are cleanup, but there is 1 correctness fix: I fixed InstCombine so that the icmp is removed only if the malloc call is removed (which requires explicit removal because the Worklist won't DCE any calls since they can have side-effects). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@84772 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-21Fix PR5262: when folding select into PHI, make sure all operands are availableTorok Edwin
in the PHI's Basic Block. This uses a conservative approach, because we don't have dominator info in instcombine. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@84754 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-21Add a pass to overlay pic16 data sections for function frame and automaticSanjiv Gupta
variables. This pass can be invoked by llvm-ld or opt to traverse over the call graph to detect what function frames and their automatic variables can be overlaid. Currently this builds an archive , but needs to be changed to a loadable module. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@84753 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-21make GVN work better when TD is not around:Chris Lattner
"In the existing code, if the load and the value to replace it with are of different types *and* target data is available, it tries to use the target data to coerce the replacement value to the type of the load. Otherwise, it skips all effort to handle the type mismatch and just feeds the wrongly-typed replacement value to replaceAllUsesWith, which triggers an assertion. The patch replaces it with an outer if checking for type mismatch, and an inner if-else that checks whether target data is available and, if not, returns false rather than trying to replace the load."
