| * | -fcatch-undefined-behavior: add the -ftrapv checks to the set of things caught | Richard Smith | 2012-08-25 | 1 | -0/+20 |
| | | | | | | | | | | | | | | | | | by this mode, and also check for signed left shift overflow. The rules for the latter are a little subtle: * neither C89 nor C++98 specify the behavior of a signed left shift at all * in C99 and C11, shifting a 1 bit into the sign bit has undefined behavior * in C++11, with core issue 1457, shifting a 1 bit *out* of the sign bit has undefined behavior As of this change, we use the C99 rules for all C language variants, and the C++11 rules for all C++ language variants. Once we have individual -fcatch-undefined-behavior= flags, this should be revisited. llvm-svn: 162634 | ||||

| * when checking that a pointer or reference refers to appropriate storage for a type, also check the alignment and perform a null check * check that references are bound to appropriate storage * check that 'this' has appropriate storage in member accesses and member function calls llvm-svn: 162523 | |||||
