* Make blockaddress(@func, null) be valid, and make 'deleting a basic Chris Lattner2009-10-311-5/+11
| | | | | | | | | | | | block with a blockaddress still referring to it' replace the invalid blockaddress with a new blockaddress(@func, null) instead of a inttoptr(1). This changes the bitcode encoding format, and still needs codegen support (this should produce a non-zero value, referring to the entry block of the function would also be quite reasonable). llvm-svn: 85678
* full asmparser support for blockaddress. We can now do:Chris Lattner2009-10-284-40/+172
| | | | | | | | | $ llvm-as foo.ll -d -disable-output which reads and prints the .ll file. BC encoding is the next project. Testcase will go in once that works. llvm-svn: 85368

* Remove FreeInst.Victor Hernandez2009-10-261-1/+4
| | | | | | | Remove LowerAllocations pass. Update some more passes to treate free calls just like they were treating FreeInst. llvm-svn: 85176
* fix PR5295 where the .ll parser didn't reject a function after a globalChris Lattner2009-10-251-5/+8

* Auto-upgrade free instructions to calls to the builtin free function.Victor Hernandez2009-10-242-4/+5
| | | | | | | Update all analysis passes and transforms to treat free calls just like FreeInst. Remove RaiseAllocations and all its tests since FreeInst no longer needs to be raised. llvm-svn: 84987

* Make changes to rev 84292 as requested by Chris Lattner.Victor Hernandez2009-10-211-23/+18
| | | | | | | 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). llvm-svn: 84772

| | | | | | | | | | | | | | | | | Constant uniquing tables. This allows distinct ConstantExpr objects with the same operation and different flags. Even though a ConstantExpr "a + b" is either always overflowing or never overflowing (due to being a ConstantExpr), it's still necessary to be able to represent it both with and without overflow flags at the same time within the IR, because the safety of the flag may depend on the context of the use. If the constant really does overflow, it wouldn't ever be safe to use with the flag set, however the use may be in code that is never actually executed. This also makes it possible to merge all the flags tests into a single test. llvm-svn: 80998
