* [Modules] Fix potential ODR violations by sinking the DEBUG_TYPEChandler Carruth2014-04-22
| | | | | | | | | | | | | | | | | definition below all of the header #include lines, lib/Transforms/... edition. This one is tricky for two reasons. We again have a couple of passes that define something else before the includes as well. I've sunk their name macros with the DEBUG_TYPE. Also, InstCombine contains headers that need DEBUG_TYPE, so now those headers #define and #undef DEBUG_TYPE around their code, leaving them well formed modular headers. Fixing these headers was a large motivation for all of these changes, as "leaky" macros of this form are hard on the modules implementation. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@206844 91177308-0d34-0410-b5e6-96231b3b80d8
* [C++11] Add range based accessors for the Use-Def chain of a Value.Chandler Carruth2014-03-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This requires a number of steps. 1) Move value_use_iterator into the Value class as an implementation detail 2) Change it to actually be a *Use* iterator rather than a *User* iterator. 3) Add an adaptor which is a User iterator that always looks through the Use to the User. 4) Wrap these in Value::use_iterator and Value::user_iterator typedefs. 5) Add the range adaptors as Value::uses() and Value::users(). 6) Update *all* of the callers to correctly distinguish between whether they wanted a use_iterator (and to explicitly dig out the User when needed), or a user_iterator which makes the Use itself totally opaque. Because #6 requires churning essentially everything that walked the Use-Def chains, I went ahead and added all of the range adaptors and switched them to range-based loops where appropriate. Also because the renaming requires at least churning every line of code, it didn't make any sense to split these up into multiple commits -- all of which would touch all of the same lies of code. The result is still not quite optimal. The Value::use_iterator is a nice regular iterator, but Value::user_iterator is an iterator over User*s rather than over the User objects themselves. As a consequence, it fits a bit awkwardly into the range-based world and it has the weird extra-dereferencing 'operator->' that so many of our iterators have. I think this could be fixed by providing something which transforms a range of T&s into a range of T*s, but that *can* be separated into another patch, and it isn't yet 100% clear whether this is the right move. However, this change gets us most of the benefit and cleans up a substantial amount of code around Use and User. =] git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@203364 91177308-0d34-0410-b5e6-96231b3b80d8

* inalloca: Don't remove dead arguments in the presence of inalloca argsReid Kleckner2014-02-03
| | | | | | | | | | | | It disturbs the layout of the parameters in memory and registers, leading to problems in the backend. The plan for optimizing internal inalloca functions going forward is to essentially SROA the argument memory and demote any captured arguments (things that aren't trivially written by a load or store) to an indirect pointer to a static alloca. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200717 91177308-0d34-0410-b5e6-96231b3b80d8

* Fix a bug in Dead Argument Elimination.Shuxin Yang2013-10-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If a function seen at compile time is not necessarily the one linked to the binary being built, it is illegal to change the actual arguments passing to it. e.g. -------------------------- void foo(int lol) { // foo() has linkage satisifying isWeakForLinker() // "lol" is not used at all. } void bar(int lo2) { // xform to foo(undef) is illegal, as compiler dose not know which // instance of foo() will be linked to the the binary being built. foo(lol2); } ----------------------------- Such functions can be captured by isWeakForLinker(). NOTE that mayBeOverridden() is insufficient for this purpose as it dosen't include linkage types like AvailableExternallyLinkage and LinkOnceODRLinkage. Take link_odr* as an example, it indicates a set of *EQUIVALENT* globals that can be merged at link-time. However, the semantic of *EQUIVALENT*-functions includes parameters. Changing parameters breaks the assumption. Thank John McCall for help, especially for the explanation of subtle difference between linkage types. rdar://11546243 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@192302 91177308-0d34-0410-b5e6-96231b3b80d8

* Move all of the header files which are involved in modelling the LLVM IRChandler Carruth2013-01-02
| | | | | | | | | | | | | | | | | | | | | into their new header subdirectory: include/llvm/IR. This matches the directory structure of lib, and begins to correct a long standing point of file layout clutter in LLVM. There are still more header files to move here, but I wanted to handle them in separate commits to make tracking what files make sense at each layer easier. The only really questionable files here are the target intrinsic tablegen files. But that's a battle I'd rather not fight today. I've updated both CMake and Makefile build systems (I think, and my tests think, but I may have missed something). I've also re-sorted the includes throughout the project.

* Use the new script to sort the includes of every file under lib.Chandler Carruth2012-12-03
| | | | | | | | | | | | | | | | | Sooooo many of these had incorrect or strange main module includes. I have manually inspected all of these, and fixed the main module include to be the nearest plausible thing I could find. If you own or care about any of these source files, I encourage you to take some time and check that these edits were sensible. I can't have broken anything (I strictly added headers, and reordered them, never removed), but they may not be the headers you'd really like to identify as containing the API being implemented. Many forward declarations and missing includes were added to a header files to allow them to parse cleanly when included first. The main module rule does in fact have its merits. =] git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169131 91177308-0d34-0410-b5e6-96231b3b80d8
* Make the AttrListPtr object a part of the LLVMContext.Bill Wendling2012-11-20
| | | | | | | | | | When code deletes the context, the AttributeImpls that the AttrListPtr points to are now invalid.
