The isBarrier/isTerminator flags have been removed from the SystemZ trap instructions, so that tests do not fail with EXPENSIVE_CHECKS. This was just an issue at -O0 and did not affect code output on benchmarks. (Like Eli pointed out: "targets are split over whether they consider their "trap" a terminator; x86, AArch64, and NVPTX don't, but ARM, MIPS, PPC, and SystemZ do. We should probably try to be consistent here.". This is still the case, although SystemZ has switched sides). SystemZ now returns true in isMachineVerifierClean() :-) These Generic tests have been modified so that they can be run with or without EXPENSIVE_CHECKS: CodeGen/Generic/llc-start-stop.ll and CodeGen/Generic/print-machineinstrs.ll Review: Ulrich Weigand, Simon Pilgrim, Eli Friedman https://bugs.llvm.org/show_bug.cgi?id=33047 https://reviews.llvm.org/D34143 llvm-svn: 306106
