Eugene Zelenko	88025fac90	[CodeGen] Fix some Clang-tidy modernize-use-using and Include What You Use warnings; other minor fixes (NFC). ... llvm-svn: 304954	2017-06-07 23:53:32 +00:00
Keno Fischer	5d34206be4	[ExecutionDepsFix] Don't recurse over the CFG ... Summary: Use an explicit work queue instead, to avoid accidentally causing stack overflows for input with very large CFGs.

Keno Fischer	1495c2d33b	[ExecutionDepsFix] Don't revisit true dependencies ... If an instruction has a true dependency, it makes sense for to use that register for any undef read operands in the same instruction (we'll have to wait for that register to become available anyway). This logic was already implemented. However, the code would then still try to revisit that instruction and break the dependency (and always fail, since by definition a true dependency has to be live before the instruction). Avoid revisiting such instructions as a performance optimization. No functional change. Differential Revision: https://reviews.llvm.org/D30173 llvm-svn: 299467	2017-04-04 20:30:47 +00:00
Matthias Braun	ea69eb48b2	ExecutionDepsFix: Let targets specialize the pass; NFC ... Let targets specialize the pass with the register class so we can get a parameterless default constructor and can put the pass into the pass registry to enable testing with -run-pass=. llvm-svn: 298184	2017-03-18 05:08:58 +00:00
