2012-11-07When we're updating the subprogram scope DIE, we want to determine if we'reBill Wendling
updating an abstract DIE or not. If we are, then we use that. Its children will be added on later, as well as the object pointer attribute. Otherwise, this function may be called with a concrete DIE twice and adding the children and object pointer attribute to it twice. <rdar://problem/12401423&12600340> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@167524 91177308-0d34-0410-b5e6-96231b3b80d8
2012-11-01Revert the majority of the next patch in the address space series:Chandler Carruth
r165941: Resubmit the changes to llvm core to update the functions to support different pointer sizes on a per address space basis. Despite this commit log, this change primarily changed stuff outside of VMCore, and those changes do not carry any tests for correctness (or even plausibility), and we have consistently found questionable or flat out incorrect cases in these changes. Most of them are probably correct, but we need to devise a system that makes it more clear when we have handled the address space concerns correctly, and ideally each pass that gets updated would receive an accompanying test case that exercises that pass specificaly w.r.t. alternate address spaces. However, from this commit, I have retained the new C API entry points. Those were an orthogonal change that probably should have been split apart, but they seem entirely good. In several places the changes were very obvious cleanups with no actual multiple address space code added; these I have not reverted when I spotted them. In a few other places there were merge conflicts due to a cleaner solution being implemented later, often not using address spaces at all. In those cases, I've preserved the new code which isn't address space dependent. This is part of my ongoing effort to clean out the partial address space code which carries high risk and low test coverage, and not likely to be finished before the 3.2 release looms closer. Duncan and I would both like to see the above issues addressed before we return to these changes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@167222 91177308-0d34-0410-b5e6-96231b3b80d8

2012-07-06Fix PR13202 and a regtest.Alexey Samsonov
DwarfDebug class could generate the same (inlined) DIVariable twice: 1) when trying to find abstract debug variable for a concrete inlined instance. 2) when explicitly collecting info for variables that were optimized out. This change makes sure that this duplication won't happen and makes Clang pass "gdb.opt/inline-locals" test from gdb testsuite.

2012-06-01Switch all register list clients to the new MC*Iterator interface.Jakob Stoklund Olesen
No functional change intended. Sorry for the churn. The iterator classes are supposed to help avoid giant commits like this one in the future.
