2009-03-13Fix -strip-debug-declare to work when there areDale Johannesen
llvm.global.variable's but no llvm.declare's. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@66977 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-13Fix PR3784: If the source of a phi comes from a bb ended with an invoke, ↵Evan Cheng
make sure the copy is inserted before the try range (unless it's used as an input to the invoke, then insert it after the last use), not at the end of the bb. Also re-apply r66140 which was disabled as a workaround. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@66976 91177308-0d34-0410-b5e6-96231b3b80d8

2009-03-13Second installment of "BasicBlock operands to the back"Gabor Greif
changes. For InvokeInst now all arguments begin at op_begin(). The Callee, Cont and Fail are now faster to get by access relative to op_end(). This patch introduces some temporary uglyness in CallSite. Next I'll bring CallInst up to a similar scheme and then the uglyness will magically vanish. This patch also exposes all the reliance of the libraries on InvokeInst's operand ordering. I am thinking of taking care of that too. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@66920 91177308-0d34-0410-b5e6-96231b3b80d8

2009-03-12Previous debug info fix to this code wasn't quiteDale Johannesen
right; did the wrong thing when there are exactly 11 non-debug instructions, followed by debug info. Remove a FIXME since it's apparently been fixed along the way. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@66840 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-12Revert commit 66140 since it caused several failuresDuncan Sands
in the Ada testcase. Reverting this only covers up the real problem, which is a nasty conceptual difficulty in the phi elimination pass: when eliminating phi nodes in landing pads, the register copies need to come before the invoke, not at the end of the basic block which is too late...

2009-03-07Introduce new linkage types linkonce_odr, weak_odr, common_odrDuncan Sands
and extern_weak_odr. These are the same as the non-odr versions, except that they indicate that the global will only be overridden by an *equivalent* global. In C, a function with weak linkage can be overridden by a function which behaves completely differently. This means that IP passes have to skip weak functions, since any deductions made from the function definition might be wrong, since the definition could be replaced by something completely different at link time. This is not allowed in C++, thanks to the ODR (One-Definition-Rule): if a function is replaced by another at link-time, then the new function must be the same as the original function. If a language knows that a function or other global can only be overridden by an equivalent global, it can give it the weak_odr linkage type, and the optimizers will understand that it is alright to make deductions based on the function body. The code generators on the other hand map weak and weak_odr linkage to the same thing. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@66339 91177308-0d34-0410-b5e6-96231b3b80d8

2009-03-06While thinking about the one-definition-rule and tryingDuncan Sands
to find a tiny mouse hole to squeeze through, it struck me that globals without a name can be considered internal since they can't be referenced from outside the current module. This patch makes GlobalOpt give them internal linkage. Also done for aliases even though they always have names, since in my opinion anonymous aliases should be allowed for consistency with global variables and functions. So if that happens one day, this code is ready! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@66267 91177308-0d34-0410-b5e6-96231b3b80d8
