2009-08-25Handle a corner case when extracing code regions where one of the immediate ↵Owen Anderson
successor of an extracted block contains a PHI using a value defined in the extracted region. With this patch, the partial inliner now passes MultiSource/Applications. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79963 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-24When extracting SEME regions of code, the extractor needs to update the ↵Owen Anderson

2009-08-23eliminate the "Value" printing methods that print to a std::ostream.Chris Lattner
This required converting a bunch of stuff off DOUT and other cleanups. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79819 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-17Don't crash on critical edge. Patch by Andre Tavares.Nick Lewycky
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79252 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-16Fix for PR3016: detect the tricky case, where there are Eli Friedman
unfoldable references to a PHI node in the block being folded, and disable the transformation in that case. The correct transformation of such PHI nodes depends on whether BB dominates Succ, and dominance is expensive to compute here. (Alternatively, it's possible to check whether any uses are live, but that's also essentially a dominance calculation. Another alternative is to use reg2mem, but it probably isn't a good idea to use that in simplifycfg.) Also, remove some incorrect code from CanPropagatePredecessorsForPHIs which is made unnecessary with this patch: it didn't consider the case where a PHI node in BB has multiple uses. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79174 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-05Privatize the StructType table, which unfortunately involves routing ↵Owen Anderson

2009-07-31Move a few more APIs back to 2.5 forms. The only remaining ones left to ↵Owen Anderson

2009-07-30Twines: Don't allow implicit conversion from integers, this is too tricky.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77605 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-30Switch obvious clients to Twine instead of utostr (when they were already usingDaniel Dunbar
a Twine, e.g., for names). - I am a little ambivalent about this; we don't want the string conversion of utostr, but using overload '+' mixed with string and integer arguments is sketchy. On the other hand, this particular usage is something of an idiom. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77579 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-25More migration to raw_ostream, the water has dried up around the iostream hole.Daniel Dunbar
- Some clients which used DOUT have moved to DEBUG. We are deprecating the "magic" DOUT behavior which avoided calling printing functions when the statement was disabled. In addition to being unnecessary magic, it had the downside of leaving code in -Asserts builds, and of hiding potentially unnecessary computations. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77019 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-22Don't give a massive inlining cost bonus to available_externally Eli Friedman
functions with a single use; eliminating the single use may eliminate the function from the current module, but usually doesn't eliminate it from the final program. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@76730 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-17Replace isTrapping with a new, similar method called Eli Friedman
isSafeToSpeculativelyExecute. The new method is a bit closer to what the callers actually care about in that it rejects more things callers don't want. It also adds more precise handling for integer division, and unifies code for analyzing the legality of a speculative load. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@76150 91177308-0d34-0410-b5e6-96231b3b80d8
