2009-04-18I didn't understand how @catches were chained. Now that I get it, fixChris Lattner
the scope checker to not think @catches are nested in each other, eliminating some bogus notes. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69486 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-18reject invalid jumps among pieces of @try blocks. This seems to workChris Lattner
reasonably well except for the problem that @catches are nested within each other in the AST, giving the ugly diagnostics in L8. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69477 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-18unconditionally check for goto correctness. This is because switchChris Lattner
statements don't end up in the LabelMap so we don't have a quick way to filter them. We could add state to Sema (a "has vla" and "has jump" bit) to try to filter this out, but that would be sort of gross and I'm not convinced it is the best way. Thoughts welcome. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69476 91177308-0d34-0410-b5e6-96231b3b80d8

"Type Info" parameter. The type info parameter knows how to iterate over its arguments. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69469 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-18abstract the SwitchStack for blocks just like we do the goto labels.Chris Lattner
This fixes a crash on invalid (test10). rdar://6805469 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69465 91177308-0d34-0410-b5e6-96231b3b80d8

call ActOnBlockError so that CurBlock gets popped. This fixes a crash on test/block-syntax-error.c when this new assertion is enabled. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69464 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-18refactor some code, adding a new getLabelMap() accessor methodChris Lattner
so that clients can't poke the function-local one when they really want the current block label. No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69463 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-18Improve switch diagnostic to emit the "jump" message on theChris Lattner
specific bad case instead of on the switch. Putting it on the switch means you don't know what case is the problem. For example: scope-check.c:54:3: error: illegal switch case into protected scope case 2: ^ scope-check.c:53:9: note: jump bypasses initialization of variable length array int a[x]; ^ git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69462 91177308-0d34-0410-b5e6-96231b3b80d8
