Has anyone been running this? Do you need to use one of the -std= or -ansi or whatever to set the language conformance level of clang to match some assumed gcc level? Tia. Reed

Maybe try: .set noat AT is needed to create certain instructions from pseudo instructions, so you have to be careful how you use this. Some instructions that you can use in Mips assembler are in fact pseudos. While AT is not available to it (.set noat), the assembler can not assemble certain pseudos for you.

I am looking for advice on a problem observed with -fprofile-sample-use for samples built with the AutoFDO tool I took the "hmmer" benchmark out of SPEC2006 It is initially compiled clnag++ -o hmmer -O3 -std=gnu89 -DSPEC_CPU -DNDEBUG -fno-strict-aliasing -w -g *.c This baseline binary runs in about 164.2 seconds as reported by "perf stat" We build a sample file from this

the good news is that (thanks to Simon) the clang driver is working so well for Mips now that we are more or less switching away from using llc during development for all our various host/target configurations. the bad news is that we have make clang all the time and it is really slow to do that. we used to be able to just make in the lib/target/Mips and then in llc and it was really fast.

Well, you are an mclinker contributor and Google uses mclinker and now it's broken as the result of your change. I still don't see any justification to making a change in a public interface that is used by other non LLVM projects to fix some issue with clang warnings. People should be able to derive from those classes. I can't understand your reasoning as to why these classes must

I understand that but falling back makes the compilation slower. I'm wondering what could be done to remove this restriction about fast-isel not being able to handle non legal types. ________________________________________ From: Anton Korobeynikov [anton at korobeynikov.info] Sent: Sunday, August 31, 2014 12:55 AM To: Reed Kotler Cc: LLVMdev at cs.uiuc.edu Subject: Re: [LLVMdev] lowering

If you can't make an executable test from C or C++ code then how do you know something works. Just by examination of the .s?

I see what my problem is here.... I'll continue to move further. Seems like Richards fix is still okay.
