2010-09-17Add a -ftrapv-handler= option which allows a handler to invoke instead of ↵David Chisnall
simply aborting when a signed operation overflows. This mirrors the (GCC-incompatible) behaviour from clang 1.0 and 1.1 when -ftrapv was specified, but allows the handler to be defined for each compilation unit. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@114192 91177308-0d34-0410-b5e6-96231b3b80d8

2010-06-26Fix unary minus to trap on overflow with -ftrapv, refactoring binopChris Lattner
code so we can use it from VisitUnaryMinus. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@106957 91177308-0d34-0410-b5e6-96231b3b80d8
2010-06-26Implement support for -fwrapv, rdar://7221421Chris Lattner
As part of this, pull together trapv handling into the same enum. This also add support for NSW multiplies. This also makes PCH disagreement on overflow behavior silent, since it really doesn't matter except for warnings and codegen (no macros get defined etc). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@106956 91177308-0d34-0410-b5e6-96231b3b80d8
