* Fix surprising missed optimization in mergefunc where we forgot to considerNick Lewycky2011-01-271-3/+12
| | | | | | that relationships like "i8* null" is equivalent to "i32* null". llvm-svn: 124368
* Avoid modifying the OneClassForEachPhysReg map while iterating over it.Bob Wilson2011-01-271-2/+6
| | | | | | | | | Linear scan regalloc is currently assuming that any register aliased with a member of a regclass must also be in at least one regclass. That is not always true. For example, for X86, RIP is in a regclass but IP is not. If you're unlucky, this can cause a crash by invalidating the iterator. llvm-svn: 124365
* Use the incoming VT not the VT of where we're trying to store to determineEric Christopher2011-01-271-2/+2
| | | | | | | | if we can store a value. Also, the exclusion is or, not and. Fixes rdar://8920247. llvm-svn: 124357

* Fix PR9039, a use-after-free in reassociate. The issue was that theDuncan Sands2011-01-261-4/+11
| | | | | | | | operand being factorized (and erased) could occur several times in Ops, resulting in freed memory being used when the next occurrence in Ops was analyzed. llvm-svn: 124287
* AttrListPtr has an overloaded operator== which does this for us, we should useNick Lewycky2011-01-262-12/+7

* Teach mergefunc that intptr_t is the same width as a pointer. We still can'tNick Lewycky2011-01-261-1/+7
| | | | | | | merge vector<intptr_t>::push_back() and vector<void*>::push_back() because Enumerate() doesn't realize that "i64* null" and "i8** null" are equivalent. llvm-svn: 124285
* There are no vectors of pointer or arrays, so we don't need to check vectorNick Lewycky2011-01-261-7/+1

* Fix memory corruption. If one of the SCEV creation functions calls another butNick Lewycky2011-01-261-0/+2
| | | | | | | doesn't return immediately after then the insert position in UniqueSCEVs will be out of date. No test because this is a memory corruption issue. Fixes PR9051! llvm-svn: 124282
* Separate out the constant bonus from the size reduction metrics. ReworkEric Christopher2011-01-261-82/+85

* According to my auto-simplifier the most common missed simplifications inDuncan Sands2011-01-252-13/+228
| | | | | | | | | | | optimized code are: (non-negative number)+(power-of-two) != 0 -> true and (x | 1) != 0 -> true Instcombine knows about the second one of course, but only does it if X|1 has only one use. These fire thousands of times in the testsuite. llvm-svn: 124183
* Teach mergefunc how to emit aliases safely again -- but keep it turned it offNick Lewycky2011-01-251-25/+79
