It is expected and not unusual to need to update the lit test in such case. I'd need to see exactly which test breaks and how to know though.

Greetings all, As you may have noticed, there is a new vector shuffle lowering path in the X86 backend. You can try it out with the '-x86-experimental-vector-shuffle-lowering' flag to llc, or '-mllvm -x86-experimental-vector-shuffle-lowering' to clang. Please test it out! There may be some correctness bugs, I'm still fuzz testing it to shake them out. But I expect fairly few

I've created a review for your patch Mehdi: https://reviews.llvm.org/D37961 First time using `arc`, so hope things went well. - Johan On Tue, Sep 12, 2017 at 5:25 AM, Mehdi AMINI <joker.eph at gmail.com> wrote: > Hi Johan, > > 2017-09-11 14:21 GMT-07:00 Johan Engelen <jbc.engelen at gmail.com>: > >> On Fri, Sep 8, 2017 at 9:04 PM, Johan Engelen

With `save-temps` as plugin option, I get extra files for the MAIN module (called `a.o`): `a.o.opt.bc` and `a.thinlto.bc`. The `a.thinlto.bc` file contains nothing, only `source_filename = ...` . The `a.o.opt.bc` (this looks like the result after ThinLTO importing and optimization) contains the assembly block that it should not have: ``` module asm "\09.text" module asm

The fix (https://reviews.llvm.org/D37961) does not work. From what I have learned thusfar, the module identifier is used as filename sometimes (I think when writing an intermediate module index summary), and so a bunch of lit tests fail with the "fix". I'll look further into fixing this, any help is appreciated. ( One thing that may be important is to have a deterministic suffix.

The plugin version (and LLVM) are LLVM 3.9.0 (the release source tarball). I've attached the source files and the temporary files generated. `a.o` is the "MAIN" module. `b.o` is the "ASM" module. The error I get is: /usr/bin/ld: error: a.o.thinlto.o: multiple definition of 'foo' /usr/bin/ld: b.o.thinlto.o: previous definition here (the files depend on D runtime

Is there any eta for when viewvc will be back? I prefer to use viewvc because all of the commit emails have the SVN commit number, but not the corresponding git hashes, so it makes it easier to look it up. Or is there some easy way to map an svn commit number to the corresponding git hash? Douglas Yung From: Johan Engelen [mailto:jbc.engelen at gmail.com] Sent: Saturday, March 12, 2016 5:03 AM

It's currently disabled until the issues with llvm.org load would be resolved. Use klaus instead.

Hmm, I'm not able to get those .ll files to compile if I disable SSE and I end up with SSE instructions(including sqrtpd) if I don't disable it.

Hi Chandler, While doing the performance measurement on a Ivy Bridge, I ran into compile time errors. I saw a bunch of “cannot select" in the LLVM test suite with -march=core-avx-i. E.g., SingleSource/UnitTests/Vector/SSE/sse.isamax.c is failing at O3 -march=core-avx-i with: fatal error: error in backend: Cannot select: 0x7f91b99a6420: v4i32 = bitcast 0x7f91b99b0e10 [ORD=3] [ID=27]

I've run the SingleSource test suite for core-avx-i and have no failures here so a preprocessed file + commandline would be very useful if this reproduces for you still.

Dear LLVMdev, I've noticed an unusual behavior of the LLVM x86 code generator (with default options) that results in nearly a 4x slow-down in floating-point throughput for my microbenchmark. I've written a compute-intensive microbenchmark to approach theoretical peak throughput of the target processor by issuing a large number of independent floating-point multiplies. The distance
