2010-03-01Split out types that are non-canonical unless dependent as their ownJohn McCall
category. Use this in a few places to eliminate unnecessary TST cases and do some future-proofing. Provide terrible manglings for typeof. Mangle decltype with some hope of accuracy. Our manglings for some of the cases covered in the testcase are different from gcc's, which I've raised as an issue with the ABI list. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97523 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-01Keep an explicit stack of function and block scopes, each element ofDouglas Gregor
which has the label map, switch statement stack, etc. Previously, we had a single set of maps in Sema (for the function) along with a stack of block scopes. However, this lead to funky behavior with nested functions, e.g., in the member functions of local classes. The explicit-stack approach is far cleaner, and we retain a 1-element cache so that we're not malloc/free'ing every time we enter a function. Fixes PR6382. Also, tweaked the unused-variable warning suppression logic to look at errors within a given Scope rather than within a given function. The prior code wasn't looking at the right number-of-errors count when dealing with blocks, since the block's count would be deallocated before we got to ActOnPopScope. This approach works with nested blocks/functions, and gives tighter error recovery. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97518 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-01Fix the lookup of names used in a friend declaration to not attempt toChandler Carruth
re-declare them. This fixes PR6317. Also add the beginnings of an interesting test case for p1 of [class.friend] which also covers PR6317. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97499 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-01Implement jump checking for initialized c++ variables, implementingChris Lattner
a fixme and PR6451. Only perform jump checking if the containing function has no errors, and add the infrastructure needed to do this.

2010-03-01When instantiating a function-scoped enum, make sure that it and itsDouglas Gregor

2010-03-01Robustify instantiation of templates when there are errors in theDouglas Gregor
template definition. Do this both by being more tolerant of errors in our asserts and by not dropping a variable declaration completely when its initializer is ill-formed. Fixes the crash-on-invalid in PR6375, but not the original issue. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97463 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-01Don't warn about case-value conversions from a negative value to aDouglas Gregor
