# e2669397	17-Aug-2011	Chandler Carruth <chandlerc@gmail.com>	Treating the unused equality comparisons as something other than part of -Wunused was a mistake. It resulted in duplicate warnings and lots of other hacks. Instead, this should be a special sub-categ Treating the unused equality comparisons as something other than part of -Wunused was a mistake. It resulted in duplicate warnings and lots of other hacks. Instead, this should be a special sub-category to -Wunused-value, much like -Wunused-result is. Moved to -Wunused-comparison, moved the implementation to piggy back on the -Wunused-value implementation instead of rolling its own, different mechanism for catching all of the "interesting" statements. I like the unused-value mechanism for this better, but its currently missing several top-level statements. For now, I've FIXME-ed out those test cases. I'll enhance the generic infrastructure to catch these statements in a subsequent patch. This patch also removes the cast-to-void fixit hint. This hint isn't available on any of the other -Wunused-value diagnostics, and if we want it to be, we should add it generically rather than in one specific case. llvm-svn: 137822 show more ...
