2013-05-09Don't replace an alias in llvm.used with its target.Rafael Espindola
When we replace an internal alias with its target, be careful not to replace the entry in llvm.used (and llvm.compiler_used). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181524 91177308-0d34-0410-b5e6-96231b3b80d8
2013-05-06Fix const merging when an alias of a const is llvm.used.Rafael Espindola
We used to disable constant merging not only if a constant is llvm.used, but also if an alias of a constant is llvm.used. This change fixes that. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181175 91177308-0d34-0410-b5e6-96231b3b80d8
2013-05-01This patch breaks up Wrap.h so that it does not have to include all of Filip Pizlo
the things, and renames it to CBindingWrapping.h. I also moved CBindingWrapping.h into Support/. This new file just contains the macros for defining different wrap/unwrap methods. The calls to those macros, as well as any custom wrap/unwrap definitions (like for array of Values for example), are put into corresponding C++ headers. Doing this required some #include surgery, since some .cpp files relied on the fact that including Wrap.h implicitly caused the inclusion of a bunch of other things. This also now means that the C++ headers will include their corresponding C API headers; for example Value.h must include llvm-c/Core.h. I think this is harmless, since the C API headers contain just external function declarations and some C types, so I don't believe there should be any nasty dependency issues here. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180881 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-22Move C++ code out of the C headers and into either C++ headersEric Christopher
or the C++ files themselves. This enables people to use just a C compiler to interoperate with LLVM. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180063 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-22Clarify that llvm.used can contain aliases.Rafael Espindola
Also add a check for llvm.used in the verifier and simplify clients now that they can assume they have a ConstantArray. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180019 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-19MergeFunc: Make pointer and integer types generate the same hash.Benjamin Kramer
The logic that actually compares the types considers pointers and integers the same if they are of the same size. This created a strange mismatch between hash and reality and made the test case for this fail on some platforms (yay, test cases). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179905 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-18Implement a better fix for PR15185.Bill Wendling
If the return type is a pointer and the call returns an integer, then do the inttoptr convertions. And vice versa. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179817 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-15We are not able to bitcast a pointer to an integral value.Bill Wendling
Two return types are not equivalent if one is a pointer and the other is an integral. This is because we cannot bitcast a pointer to an integral value. PR15185 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179569 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-13GlobalDCE: Fix an oversight in my last commit that could lead to crashes.Benjamin Kramer
There is a Constant with non-constant operands: blockaddress. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179460 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-13Fix a scalability issue with complex ConstantExprs.Benjamin Kramer
This is basically the same fix in three different places. We use a set to avoid walking the whole tree of a big ConstantExprs multiple times. For example: (select cmp, (add big_expr 1), (add big_expr 2)) We don't want to visit big_expr twice here, it may consist of thousands of nodes. The testcase exercises this by creating an insanely large ConstantExprs out of a loop. It's questionable if the optimizer should ever create those, but this can be triggered with real C code. Fixes PR15714. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179458 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-02Use a worklist to avoid a sneaky iterator invalidation.Bill Wendling
The iterator could be invalidated when it's recursively deleting a whole bunch of constant expressions in a constant initializer. Note: This was only reproducible if `opt' was run on a `.bc' file. If `opt' was run on a `.ll' file, it wouldn't crash. This is why the test first pushes the `.ll' file through `llvm-as' before feeding it to `opt'.

2013-03-21Move library call prototype attribute inference to functionattrsMeador Inge
The simplify-libcalls pass implemented a doInitialization hook to infer function prototype attributes for well-known functions. Given that the simplify-libcalls pass is going away *and* that the functionattrs pass is already in place to deduce function attributes, I am moving this logic to the functionattrs pass. This approach was discussed during patch review: http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20121126/157465.html. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177619 91177308-0d34-0410-b5e6-96231b3b80d8

2013-03-06Generalize my previous fix for -print-options.Andrew Trick
Always print options that differ from their implicit default. At least for simple option types. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@176572 91177308-0d34-0410-b5e6-96231b3b80d8

GlobalValue linkage up to ExternalLinkage in the ExtractGV pass. This prevents linkonce and linkonce_odr symbols from being DCE'd. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@176459 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-13Retain the name of the new internal global that's been shrunk.Bill Wendling
It's possible (e.g. after an LTO build) that an internal global may be used for debugging purposes. If that's the case appending a '.b' to it makes it hard to find that variable. Steal the name from the old GV before deleting it so that they can find that variable again. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175104 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-02This patch makes "&Cls::purevfn" not an odr use. This isn't what the standardNick Lewycky
says, but that's a defect (to be filed). "Cls::purevfn()" is still an odr use. Also fixes a bug in the previous patch that caused us to not mark the function referenced just because we didn't want to mark it odr used. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174240 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-23Add the IR attribute 'sspstrong'.Bill Wendling
SSPStrong applies a heuristic to insert stack protectors in these situations: * A Protector is required for functions which contain an array, regardless of type or length. * A Protector is required for functions which contain a structure/union which contains an array, regardless of type or length. Note, there is no limit to the depth of nesting. * A protector is required when the address of a local variable (i.e., stack based variable) is exposed. (E.g., such as through a local whose address is taken as part of the RHS of an assignment or a local whose address is taken as part of a function argument.) This patch implements the SSPString attribute to be equivalent to SSPRequired. This will change in a subsequent patch. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@173230 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-23Remove the last of uses that use the Attribute object as a collection of ↵Bill Wendling

2013-01-21Have AttributeSet::getRetAttributes() return an AttributeSet instead of ↵Bill Wendling

2013-01-21Make AttributeSet::getFnAttributes() return an AttributeSet instead of an ↵Bill Wendling

2013-01-21Make the inline cost a proper analysis pass. This remains essentiallyChandler Carruth
a dynamic analysis done on each call to the routine. However, now it can use the standard pass infrastructure to reference other analyses, instead of a silly setter method. This will become more interesting as I teach it about more analysis passes. This updates the two inliner passes to use the inline cost analysis. Doing so highlights how utterly redundant these two passes are. Either we should find a cheaper way to do always inlining, or we should merge the two and just fiddle with the thresholds to get the desired behavior. I'm leaning increasingly toward the latter as it would also remove the Inliner sub-class split. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@173030 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-18Use AttributeSet accessor methods instead of Attribute accessor methods.Bill Wendling
Further encapsulation of the Attribute object. Don't allow direct access to the Attribute object as an aggregate. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@172853 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-18Push some more methods down to hide the use of the Attribute class.Bill Wendling
Because the Attribute class is going to stop representing a collection of attributes, limit the use of it as an aggregate in favor of using AttributeSet.
