JF Bastien 82d29b397b Add an unsigned shift base sanitizer ... It's not undefined behavior for an unsigned left shift to overflow (i.e. to shift bits out), but it has been the source of bugs and exploits in certain codebases in the past. As we do in other parts of UBSan, this patch adds a dynamic checker which acts beyond UBSan and checks other sources of errors. The option is enabled as part of -fsanitize=integer. The flag is named: -fsanitize=unsigned-shift-base This matches shift-base and shift-exponent flags. <rdar://problem/46129047> Differential Revision: https://reviews.llvm.org/D86000		2020-08-27 19:50:10 -07:00
