* Finally land the InvokeInst operand reordering.Gabor Greif2010-03-245-6/+7
| | | | | | | | | | | | | I have audited all getOperandNo calls now, fixing hidden assumptions. CallSite related uglyness will be eliminated successively. Note this patch has a long and griveous history, for all the back-and-forths have a look at CallSite.h's log. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99399 91177308-0d34-0410-b5e6-96231b3b80d8

* Now that hopefully all direct accesses to InvokeInst operands are fixedGabor Greif2010-03-224-7/+7
| | | | | | | | we can reapply the InvokeInst operand reordering patch. (see r98957). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99170 91177308-0d34-0410-b5e6-96231b3b80d8
* Add a setCalledFunction member to InvokeInst (like in CallInst)Gabor Greif2010-03-202-3/+3

* Clear the SCEVExpander's insertion point after making deletions,Dan Gohman2010-03-201-0/+4
| | | | | | | | | | | | | | | so that the SCEVExpander doesn't retain a dangling pointer as its insert position. The dangling pointer in this case wasn't ever used to insert new instructions, but it was causing trouble with SCEVExpander's code for automatically advancing its insert position past debug intrinsics. This fixes use-after-free errors that valgrind noticed in test/Transforms/IndVarSimplify/2007-06-06-DeleteDanglesPtr.ll and test/Transforms/IndVarSimplify/exit_value_tests.ll. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99036 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | This time I did a self-hosted bootstrap on Linux x86-64, with no problems. Let's see how darwin 64-bit self-hosting goes. At the first sign of failure I'll back this out. Maybe the valgrind bots give me a hint of what may be wrong (it at all). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98957 91177308-0d34-0410-b5e6-96231b3b80d8

* Try to keep the cached inliner costs around for a bit longer for big functions.Jakob Stoklund Olesen2010-03-093-6/+12
| | | | | | | | | | | | | | | The Caller cost info would be reset everytime a callee was inlined. If the caller has lots of calls and there is some mutual recursion going on, the caller cost info could be calculated many times. This patch reduces inliner runtime from 240s to 0.5s for a function with 20000 small function calls. This is a more conservative version of r98089 that doesn't break the clang test CodeGenCXX/temp-order.cpp. That test relies on rather extreme inlining for constant folding. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98099 91177308-0d34-0410-b5e6-96231b3b80d8
