In a boolean context, this is always true.if (x | 0x4) {} // always true, intended '&'This patch creates a new warning group -Wtautological-bitwise-compare for thiswarning. It also moves in the existing tautological bitwise comparisons intothis group. A few other changes were needed to the CFGBuilder so that all boolcontexts would be checked. The warnings in -Wtautological-bitwise-compare willbe off by default due to using the CFG.Fixes: https://bugs.llvm.org/show_bug.cgi?id=42666Differential Revision: https://reviews.llvm.org/D66046llvm-svn: 375318 List of files: /llvm-project-15.0.7/clang/test/SemaCXX/warn-bitwise-compare.cpp Sat, 19 Oct 2019 00:57:23 +0000 Richard Trieu <rtrieu@google.com>
