* Don't always create a separate block for the call to _Unwind_Resume.Bill Wendling2012-01-28
| | | | | | | | | | | | Sometimes there is only one 'resume' instruction per function. In those situations, we don't need a separate block for the call to _Unwind_Resume. In fact, it adds a lot of overhead to code-gen if we do that -- especially at -O0. If we have a single 'resume' instruction, just generate the call within that block. <rdar://problem/10694814> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@149159 91177308-0d34-0410-b5e6-96231b3b80d8

* The ARM stuff already calls the Resume function, not the Resume_or_Rethrow. ItBill Wendling2011-06-01
| | | | | | | | | | | | | | turns out that it could cause an infinite loop in some situations. If this code is triggered and it converts a cleanup into a catchall, but that cleanup was in already in a cleanup, then the _Unwind_SjLj_Resume could infinite loop. I.e., the code doesn't consume the exception object and passes it on to _Unwind_SjLj_Resume. But _USjLjR expects it to be consumed (since it's landing at a catchall instead of a cleanup). So it uses the values that are presently there, which are the values that tell it to jump to the fake landing pad. <rdar://problem/9508402> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132381 91177308-0d34-0410-b5e6-96231b3b80d8

* Implement and document the llvm.eh.resume intrinsic, which isJohn McCall2011-05-28
| | | | | | | | | | | | | | | | | | | transformed by the inliner into a branch to the enclosing landing pad (when inlined through an invoke). If not so optimized, it is lowered DWARF EH preparation into a call to _Unwind_Resume (or _Unwind_SjLj_Resume as appropriate). Its chief advantage is that it takes both the exception value and the selector value as arguments, meaning that there is zero effort in recovering these; however, the frontend is required to pass these down, which is not actually particularly difficult. Also document the behavior of landing pads a bit better, and make it clearer that it's okay that personality functions don't always land at landing pads. This is just a fact of life. Don't write optimizations that rely on pushing things over an unwind edge. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132253 91177308-0d34-0410-b5e6-96231b3b80d8

* There are some situations which can cause the URoR hack to infinitely recurseBill Wendling2011-03-15
| | | | | | | | | | | | | | and then go kablooie. The problem was that it was tracking the PHI nodes anew each time into this function. But it didn't need to. And because the recursion didn't know that a PHINode was visited before, it would go ahead and call itself. There is a testcase, but unfortunately it's too big to add. This problem will go away with the EH rewrite. <rdar://problem/8856298> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@127640 91177308-0d34-0410-b5e6-96231b3b80d8

* Get rid of static constructors for pass registration. Instead, every pass ↵Owen Anderson2010-10-19
| | | | | | | | | | | | | | | | | | exposes an initializeMyPassFunction(), which must be called in the pass's constructor. This function uses static dependency declarations to recursively initialize the pass's dependencies. Clients that only create passes through the createFooPass() APIs will require no changes. Clients that want to use the CommandLine options for passes will need to manually call the appropriate initialization functions in PassInitialization.h before parsing commandline arguments. I have tested this with all standard configurations of clang and llvm-gcc on Darwin. It is possible that there are problems with the static dependencies that will only be visible with non-standard options. If you encounter any crash in pass registration/creation, please send the testcase to me directly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@116820 91177308-0d34-0410-b5e6-96231b3b80d8
