| * | Add -Wtautological-compare to -Wall | Weverything | 2019-11-12 | 1 | -0/+1 |
| | | | | | | | | | Some warnings in -Wtautological-compare subgroups are DefaultIgnore. Adding this group to -Wmost, which is part of -Wall, will aid in their discoverability. Differential Revision: https://reviews.llvm.org/D69292 | ||||
| * | New tautological warning for bitwise-or with non-zero constant always true. | Richard Trieu | 2019-10-19 | 1 | -1/+20 |
| | | | | | | | | | | | | | | | | | | | Taking a value and the bitwise-or it with a non-zero constant will always result in a non-zero value. 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 this warning. It also moves in the existing tautological bitwise comparisons into this group. A few other changes were needed to the CFGBuilder so that all bool contexts would be checked. The warnings in -Wtautological-bitwise-compare will be off by default due to using the CFG.

| * | Add a check for tautological bitwise comparisons to -Wtautological-compare. | Jordan Rose | 2014-05-20 | 1 | -0/+28 |
| This catches issues like: if ((x & 8) == 4) { ... } if ((x | 4) != 3) { ... } Patch by Anders Rönnholm! llvm-svn: 209221 | |||||
