[LLVMdev] asm-verbose (on by default) is really, really slow
Very true, but we do want the testsuite to run fast. Can it be sped up? -Chris On Dec 12, 2010, at 10:57 AM, Anton Korobeynikov <anton at korobeynikov.info> wrote:>> Maybe this should be off by default? > It's off by default on any user-visible tools (e.g. clang / llvm-gcc). > Since llc is a developer tool it does make sense to enable verbose > output by default. > > -- > With best regards, Anton Korobeynikov > Faculty of Mathematics and Mechanics, Saint Petersburg State University > _______________________________________________ > LLVM Developers mailing list > LLVMdev at cs.uiuc.edu http://llvm.cs.uiuc.edu > http://lists.cs.uiuc.edu/mailman/listinfo/llvmdev

This can slow down compilation and is not what the # compilers default to using. LLCFLAGS += -asm-verbose=false Most (new) nightly testers run TEST=simple which doesn't invoke llc at all. /jakob -------------- next part -------------- A non-text attachment was scrubbed...
