similar to: [LLVMdev] Cygwin support completely dropped?

Hi there it seems that it has been sometime that anyone had success with building llvm (2.0 or 2.1 prerelease) on Cygwin/XP. i have been using gcc-4.0.2 with no success. is anyone working on Cygwin or not? i feel that having Cygwin as a supported platform is at least misleading since noone is building on Cygwin. I recall llvm-1.4 to 1.6 building decently on Cygwin even with gcc-3.3.3. Kind

Hello, Well theres not too much to it. A patch for Cygwin's stdint.h. And a patch for lib/System/Unix/Program.inc. Despite Cygwin complaining of timing errors both LLVM and LLVM-GCC4 compile ok'ish. make[2]: Warning: File `/dev/null' has modification time 0.0096 s in the future make[2]: warning: Clock skew detected. Your build may be incomplete. I am getting this on both

What is the recommended way to get a front-end to run on Windows? I have been able to successfully compile on Linux. I'm worried about documents stating all the shortcomings of the Visual Studio compiled version, but I do have mingw. Is there a guide for using mingw to compile? I thought about compiling to IR, but the documentation said the language is not stable.

Hi, I followed the build instructions at http://www.aarongray.org/LLVM/BuildingLLVMonCygwin.html to build LLVM and LLVM GCC. Everything went fine except for the 'make install' step of llvm. At this step, I am getting a big list of files which are under /cygdrive/c/llvm-2.8/include/llvm and /cygdrive/c/llvm-2.8/include/llvm-c. The error I am getting is: /usr/bin/install:

Hi there i would like to ask a few questions to the developers responsible for the register allocator(s) design in LLVM (Fernando and other people). First of all, congrats on providing more than one option for register allocation. Now to the questions: 1. I can see the standard algorithms (bigblock, linearscan -- good choice for the JIT and for general use as well, and the other algorithms).

Hi, > Can you post the llc command line you're using? Can you post an LLVM IR > file that causes this behavior? yes: ${LLVM_PATH}/bin/llc -o helloworld.s -march=nvptx helloworld.ll where LLVM_PATH my local installation path for LLVM.

Hi Nikolaos, Following commands work great for me. $ clang -S -emit-llvm -target nvptx -x cl -include clc/clctypes.h ../data-types/scalar.cl $ llc -mcpu=sm_30 scalar.s You can follow Justin's blog [1]. It helped me a lot to understand where to start. [1] http://jholewinski.org/blog/llvm-3-0-ptx-backend/ Best, Ankur On Mon, Feb 4, 2013 at 11:40 PM, Justin Holewinski < justin.holewinski

Hi all, i'm just starting out with LLVM (although i've been observing its evolution since that first release some years ago :) I would like to develop a backend for a generic assembly-like language, called NAC (N-Address Code). More info on NAC can be found here: http://www.nkavvadias.com/hercules/nac-refman.html (HTML) http://www.nkavvadias.com/hercules/nac-refman.pdf (PDF) You

Hi all, i'm writing a TXL (http://www.txl.ca) grammar and a revamp of bison/flex grammar for LLVM. I've noticed an inconsistency regarding label naming conventions. For instance, the following is a segment of legit LLVM assembly (human-readable) IR: br i1 %38, label %17, label %39 ; <label>:39 ; preds = %._crit_edge ret void

Hi there, I have a question on the LLVM internals. Is it possible to dump an InstructionList (i.e. a (possibly) naively scheduled assembly) prior register allocation? Does LLVM use infinite (virtual) registers similar to MachSUIF? This is, of course, meant for a given target in contrast to MachSUIF that features the SUIFvm ISA as low-level IR and such a dump is possible at this point. Plus:
