similar to: [LLVMdev] A partial reply to the previous question and another one

Hi. My name is Gil Dogon and I am working in MobileEye using LLVM in order to generate code for a proprietary processor. Our processor architecture is very similar to MIPS, so I started to work using the "experimental" MIPS back end. Anyway, my question is rather simple but somehow I did not find a quick answer to it in the documentation. What I want to know, is how can the

Hi all, while writing a testcase thate needed to do a grep containg {, I found that the DejaGNU test framework didn't handle those very well. It's a bit of a fuss to escape accolades properly, but most of all the framework seemed to silently ignore errors in the escaping (and just not run the command then). See [1]. Fixing the framework resulted in 80 of the tests failing. I spent the

Are you looking for something other than calling __builtin_clz from c++ or calling @llvm.ctlz.* instrinsic from IR? I don't think we have anything that will auto converting a loop to ctlz or anything like that. We only seem to have a detection for popcount loops.

Hi, I started playing with llvm on Darwin. When I do a "make check" from the llvm root, I am getting these failed tests: Failing Tests (13):     LLVM :: FrontendC++/2010-04-30-OptimizedMethod-Dbg.cpp     LLVM :: FrontendC++/2010-05-12-PtrToMember-Dbg.cpp     LLVM :: FrontendC/2007-05-16-EmptyStruct.c     LLVM :: FrontendC/2007-10-01-BuildArrayRef.c     LLVM ::

Hi all, When using "make check" with the DejaGNU test collection, I encounter two unexpected failures (they seem to be closely related). My question: are they well known, and if so what's the problem and how can I fix it? This is the error text I get: FAIL: /var/data/common/trunk/llvm/test/FrontendC/2008-05-19-AlwaysInline.c Failed with exit(1) at line 1 while running:

Does anyone know some simple c/c++ code or .ll code which will cause this ctlz pattern to be emitted? Tia. Reed

Developers, As part of PR411, I have made several of the intrinsic functions non- overloaded. While the assembler and bytecode reader are backwards compatible, front-end writers should start using the non-overloaded versions of the intrinsics. The llvm-gcc has already been updated to generate the new intrinsic names. Other front-ends will start seeing warnings about the names of intrinsics that

Hi, SystemZ supports @llvm.ctlz.i64() natively with a single instruction (FLOGR), and lesser bitwidth versions of the intrinsic are promoted to i64. For some reason, this leads to unfolded additions of constants as shown below: This function: define i16 @fun(i16 %arg) {   %1 = tail call i16 @llvm.ctlz.i16(i16 %arg, i1 false)   ret i16 %1 } ,gives this optimized DAG as input to instruction

I successfully built LLVM (r102824) with ./configure --enable-optimized --enable-targets=host --with-built-clang on Fedora 12 on an Athlon64 processor. (The clang is the 2.7 pre-built version.) However, running `make check' produced 6 unexpected failures (see below). If there's something you'd like me to do, just holler. --- Vladimir FAIL:

As mentioned in an earlier mail, I am working on an LLVM backend for a custom processor based on MIPS. My problem is how to extend LLVM to support some esoteric/non-standard feature of the underlying hardware. I saw in the "Extending LLVM" document, that the easiest / most common way to do this was using an intrinsic function, and examples of the technique abound (all SSE for

Hi all, Some non trivial legalization of operations which aren't supported by the backend would benefit from having the optimizer pass on them. I noticed some example trying to optimize various pieces of code over the past weeks. One offender is the cttz/ctlz intrinsic when defined on 0. On X86, BSR and NSF are undefined on 0, and only recent CPU have the LZCNT and TZCNT instructions that
