Hi Kostis, Just to check, did you send the patch originally to llvmdev or llvm-commits? The latter is where all commit review takes place.

This patch (and the others that will follow) are rebased on svn r155440: "AVX2: The BLENDPW instruction selects between vectors of v16i16 using an i8 immediate. We can't use it here because the shuffle code does not check that the lower part of the word is identical to the upper part" Patch 1/3: The attached commits add a new calling convention to support the LLVM backend for

Hi, We 've been working on an LLVM backend for High Performance Erlang (HiPE) [1], the native code compiler of Erlang/OTP [2]. ErLLVM [3] targets the X86 and AMD64 architectures for now but there is some ongoing work from a team on the Uppsala University to also support ARM. In our implementation, we have paid special attention on retaining ABI-compatibility with the Erlang Runtime System in

Hi, Following Chris' advice, I will rebase the patches and break them in 3 distinct emails (one at a time) in order to be easier for a reviewer to approve/comments. Please note that the three patches while being code-wise independent, they 're strongly-connected *semantically*, meaning that including just a subset of these patches to LLVM's code base is quite weak if the others are

I have a bit of a riddle: In http://reviews.llvm.org/D19904 I'm trying to spell the following assembly: .palign 2, 0x90 jmp +0x9 nopw 512(%rax,%rax,1) // rest of the code I try the following snippet to accomplish this: OutStreamer->EmitLabel(CurSled); OutStreamer->EmitCodeAlignment(4); auto Target = OutContext.createLinkerPrivateTempSymbol(); // Use a two-byte `jmp`.

Peter suggested just writing out '.byte 0xeb, 0x09' and that allowed the jump instruction to bypass the relaxation, so that fixes my immediate problem. The question still stands though whether it should be possible to do through the instruction builder interface.

Thanks Nirav, I can confirm that this works when I do the compile with llc, but then when linking to an executable with clang (patched with http://reviews.llvm.org/D20352 and compiler-rt patched with http://reviews.llvm.org/D21612) on Linux, I'm getting something different. Here's a sample of the transcript, and what I'm seeing: --->8 clang invocation 8<--- [16-06-23 3:33:42]

Sorry for double-posting to the list, The citation is the following (this time with a url to the paper): K. Sagonas, C. Stavrakakis, and Y. Tsiouris. "ErLLVM: An LLVM backend for Erlang"[1].

Hi, I attach a publication that we have at the ACM Sigplan Erlang Workshop 2012, Copenhagen, Denmark. The abstract is: This paper describes ErLLVM, a new backend for the HiPE compiler, the native code compiler of Erlang/OTP, that targets the LLVM compiler infrastructure. Besides presenting the overall architecture of ErLLVM and its integration in Erlang/OTP, we describe the changes to LLVM that

Hi, I would be very grateful for advice on getting confidence intervals for the ordinary (non smoothed) parameter estimates from a gam. Motivation I am studying hospital outcomes in a large data set. The outcomes of interest to me are all binary variables. The one in the example here, Dead30d, is death within 30 days of admission. Sexf is gender (M or F), Age is age in years at the start

Hi, After reading https://llvm.org/docs/Vectorizers.html#vectorization-of-function-calls I decided to write the following C++ program: #include <cmath> using v4f32 = float __attribute__((__vector_size__(16))); v4f32 fct1(v4f32 x) { v4f32 y; y[0] = std::sin(x[0]); y[1] = std::sin(x[1]); y[2] = std::sin(x[2]); y[3] = std::sin(x[3]); return y; } v4f32 fct2(v4f32 x) { v4f32 y;

Hmm. Odd. I just rebuilt from scratch and it seems to work with the test/CodeGen/X86/xray-attribute-instrumentation.ll test case outputing straight to obj: llc -filetype=obj -o ~/a.o -mtriple=x86_64-apple-macosx < test/CodeGen/X86/xray-attribute-instrumentation.ll What test case are you using? In any case, the issue appears to be that llvm doesn't realize that the target address is
