* Add a pass to overlay pic16 data sections for function frame and automaticSanjiv Gupta2009-10-2111-6/+341
| | | | | | | | | | 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

* make GVN work better when TD is not around:Chris Lattner2009-10-211-15/+21
| | | | | | | | | | | | | | | | | | | "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."

* Move the Function*->allocated blocks map from the JITMemoryManager to theJeffrey Yasskin2009-10-202-34/+30
| | | | | | | | | | | | | | | | | JITEmitter. I'm gradually making Functions auto-remove themselves from the JIT when they're destroyed. In this case, the Function needs to be removed from the JITEmitter, but the map recording which Functions need to be removed lived behind the JITMemoryManager interface, which made things difficult. This patch replaces the deallocateMemForFunction(Function*) method with a pair of methods deallocateFunctionBody(void *) and deallocateExceptionTable(void *) corresponding to the two startFoo/endFoo pairs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@84651 91177308-0d34-0410-b5e6-96231b3b80d8

This fixes a problem resulting from the LowerOperation hooks being called from LegalizeVectorOps, because LegalizeVectorOps only lowers vectors, so OEQ and UNE comparisons may still be at large.

| | | | | | | | | | | when the invoke had multiple return values: it set the lattice value only on the extractvalue. This caused the invoke's lattice value to remain the default (undefined), and later propagated to extractvalue's operand, which incorrectly introduces undefined behavior. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@84637 91177308-0d34-0410-b5e6-96231b3b80d8
