similar to: [LLVMdev] ENABLE_OPTIMIZED=1

I used the A9 schedule as an example: http://llvm.org/svn/llvm-project/llvm/trunk/lib/Target/ARM/ARMScheduleA9.td The documentation could use more clarity, but this is how I was able to do it to always get two specific instructions to be scheduled together. ________________________________________ From: reed kotler [rkotler at mips.com] Sent: Tuesday, September 17, 2013 8:54 PM To: Micah Villmow

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

The issues seems to be this line in the tools Makefile timeit-target: timeit.c $(LD_ENV_OVERRIDES) $(LCC) -o $@ $< $(LDFLAGS) $(CFLAGS) $(TARGET_FLAGS) -O3 It should not add target flags if we are simulating the target on the host.

One could argue that mclinker is doing something good or not by how it's using this class but I don't see the need for parser<bool> to be final. That is a subjective opinion that mclinker needs to be changed. I think that "final" was added to some of these command line classes to avoid some kind of clang warning. That seems wrong to me that the tools are dictating

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

Reed, Couldn't you also use instruction scheduling classes and specify that the second instruction has a bypass from the first instruction? The scheduler should always schedule them together in that case.

That doesn't actually give you a guarantee that they won't be split up. Phases other than the scheduler may insert instructions in the middle of block (constant island pass, for example). Pseudo-instructions are the canonical answer to that problem. --Owen On Sep 17, 2013, at 11:09 PM, Micah Villmow <micah.villmow at smachines.com> wrote: > I used the A9 schedule as an

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

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 want to get lnt to use qemu for the execution. In that case, RHOST= is not set. But I change the Arch because I am going to run in cross mode. Then I'm setting RUNUNDER to be a script which runs qemu. In this case it builds timeit-target as a Mips which fails because this is running on x86. ~/mysandbox/bin/lnt runtest nt --sandbox ~/mysandbox --cc /local/llvmpb_a/install/bin/clang

Okay. Cool. So do you bootrstrap and verify as part of the usual testing? Do the nightly scripts do this?
