The current "longest match takes precedence" rule for warning suppression mappings can be confusing, especially in long suppression files where tracking the length relationship between globs is difficult. For example, with the following rules, it's not immediately obvious why the first one should currently take precedence: ``` src:*test/* src:*lld/*=emit ``` This commit changes the multi-match behavior so the last match takes precedence. This rule is easier to understand and consistent with the approach used by sanitizers, simplifying the mechanism by providing a uniform experience across different tools. This is potentially breaking, but very unlikely. An investigation of known uses showed they do not rely on the length.
