2008-05-05Improve leak diagnostics to not report a leak on the same line where Ted Kremenek

highlight the most nested subexpression that appears most responsible (giving the user better diagnostic feedback). Updated test cases to illustrate this feature. Implements: <rdar://problem/5880443> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@50647 91177308-0d34-0410-b5e6-96231b3b80d8

2008-05-05Neil pointed out that clang doesn't generate ranges from diagnosticsChris Lattner
related to pp-expressions. Doing so is pretty simple and this patch implements it, yielding nice diagnostics like: t.c:2:7: error: division by zero in preprocessor expression #if 1 / (0 + 0) ~ ^ ~~~~~~~ t.c:5:14: error: expected ')' in preprocessor expression #if (412 + 42 ~~~~~~~~^ t.c:5:5: error: to match this '(' #if (412 + 42 ^ t.c:10:10: warning: left side of operator converted from negative value to unsigned: -42 to 18446744073709551574 #if (-42 + 0U) / -2 ~~~ ^ ~~ t.c:10:16: warning: right side of operator converted from negative value to unsigned: -2 to 18446744073709551614 #if (-42 + 0U) / -2 ~~~~~~~~~~ ^ ~~ 5 diagnostics generated. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@50638 91177308-0d34-0410-b5e6-96231b3b80d8

2008-05-04Fix PR2281: these two warnings should be promoted to error onChris Lattner
pedantic error. Perhaps I should add a class of 'extension' that is 'extension that warns by default', which would be cleaner. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@50633 91177308-0d34-0410-b5e6-96231b3b80d8
