* Fix uninitialized memory references in WinEHPrepareAndrew Kaylor2015-03-051-1/+3
| | | | llvm-svn: 231405
* Replace llvm.frameallocate with llvm.frameescapeReid Kleckner2015-03-051-159/+54
| | | | | | | | | | Turns out it's pretty straightforward and simplifies the implementation. Reviewers: andrew.w.kaylor Differential Revision: http://reviews.llvm.org/D8051 llvm-svn: 231386
* Make DataLayout Non-Optional in the ModuleMehdi Amini2015-03-041-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: DataLayout keeps the string used for its creation. As a side effect it is no longer needed in the Module. This is "almost" NFC, the string is no longer canonicalized, you can't rely on two "equals" DataLayout having the same string returned by getStringRepresentation(). Get rid of DataLayoutPass: the DataLayout is in the Module The DataLayout is "per-module", let's enforce this by not duplicating it more than necessary. One more step toward non-optionality of the DataLayout in the module. Make DataLayout Non-Optional in the Module Module->getDataLayout() will never returns nullptr anymore.

* WinEH: Remove vestigial EH objectReid Kleckner2015-03-031-43/+13
| | | | | | | | Ultimately, we'll need to leave something behind to indicate which alloca will hold the exception, but we can figure that out when it comes time to emit the __CxxFrameHandler3 catch handler table. llvm-svn: 231164

* Revert r229944: EH: Prune unreachable resume instructions during Dwarf EH ↵Chandler Carruth2015-02-201-12/+3
| | | | | | | | | preparation This doesn't pass 'ninja check-llvm' for me. Lots of tests, including the ones updated, fail with crashes and other explosions. llvm-svn: 229952
* EH: Prune unreachable resume instructions during Dwarf EH preparationReid Kleckner2015-02-201-3/+12
| | | | | | | | | | | | | | | | | Today a simple function that only catches exceptions and doesn't run destructor cleanups ends up containing a dead call to _Unwind_Resume (PR20300). We can't remove these dead resume instructions during normal optimization because inlining might introduce additional landingpads that do have cleanups to run. Instead we can do this during EH preparation, which is guaranteed to run after inlining. Fixes PR20300. Reviewers: majnemer Differential Revision: http://reviews.llvm.org/D7744 llvm-svn: 229944

* Don't promote asynch EH invokes of nounwind functions to callsReid Kleckner2015-02-111-1/+1
| | | | | | | | | | | If the landingpad of the invoke is using a personality function that catches asynch exceptions, then it can catch a trap. Also add some landingpads to invalid LLVM IR test cases that lack them. Over-the-shoulder reviewed by David Majnemer. llvm-svn: 228782

* Add a Windows EH preparation pass that zaps resumesReid Kleckner2015-01-291-0/+106
If the personality is not a recognized MSVC personality function, this pass delegates to the dwarf EH preparation pass. This chaining supports people on *-windows-itanium or *-windows-gnu targets. Currently this recognizes some personalities used by MSVC and turns resume instructions into traps to avoid link errors. Even if cleanups are not used in the source program, LLVM requires the frontend to emit a code path that resumes unwinding after an exception. Clang does this, and we get unreachable resume instructions. PR20300 covers cleaning up these unreachable calls to resume.
