Hi James/Tim, I am trying to add a patterns for SMLALBB I think these two assembly patterns can be reduced to SMLALBB using tablegen. 1) smulbb r2, r3, r2 adds r0, r2, r0 (RdLo) asr r3, r2, #31 adc r1, r3, r1 (RdHi) ==> smlalbb r0, r1, r3, r2 I have added pattern in def SMLALBB : AMulxyI64< ..... as below :- [] modified to ---> [((set GPR:$RdLo,

Hello, I built a llvm toolchain for ARM and I'm trying to build a simple application on ARM using LLVM. When I compiled the code, it has the following message and the binary code has a segmentation fault when it is executed. /tmp/ccJPjMe4.s: Assembler messages: /tmp/ccJPjMe4.s:4250: rdhi, rdlo and rm must all be different /tmp/ccJPjMe4.s:4589: rdhi, rdlo and rm must all be different

Thanks. I could take a look at the lines and all of them have smull instruction like 'smull r0, r1, r0, r1'.

I tried a couple of options (-mcpu=arm1136j-s, -mcpu=arm1136jf-s, -march=armv6, ...) to let the compile know the specific ARM processor, but the same issue is still there. I tried to take a look at .s file in /tmp directory, but it's already cleaned up. Is it because I enabled the optimization option when I compiled llvm?

Hello > /tmp/cczBL31y.s:409: rdhi, rdlo and rm must all be different This is binutils bug fixed ~2 years ago: http://sourceware.org/ml/binutils/2007-11/msg00046.html Make sure you're using the latest binutils for ARM (from binutils CVS) -- With best regards, Anton Korobeynikov Faculty of Mathematics and Mechanics, Saint Petersburg State University

Hello, Thanks for the reply. We have an product whose one part has lot of algorithms doing some graphics work. Our intention was to figure out if there can be any performance gain if we use llvm instead of native ARM. This is for ARM target. Earlier, I have built this component using llvm and tested it on x86. Performance was 4x as compared to native gcc. Then I built llvm for ARM and tested

Hi, Any help would b appreicated. This is one of my critical assignment.

Hi, all I am trying to selfhost LLVM and Clang. Below is my flow, Step 1. Build LLVM and Clang by using native gcc $ ../llvm-2.9/configure --prefix=$INSTALL \ --enable-optimized Step 2. Build LLVM and Clang by using clang built by step 1 $ CC=clang CXX=clang++ ../llvm-2.9/configure \ --prefix=$INSTALL --enable-optimized But in step 2, I have a compilation error below, -- llvm[1]:

Hi all, There's been a recent bootstrap failure that might be covered up because of another failure. I just wanted to point this out so that people can take a look: -bw Here's the failure from our buildbot: Assertion failed: (DestReg == VirtReg && "Unknown load situation!"), function RewriteMBB, file /Volumes/Sandbox/Buildbot/llvm/build.llvm-

This looks relevant to me for your issue.

These self-host builders all just starting failing. It looks like tablegen is being miscompiled. The first failed builds: (1) http://lab.llvm.org:8011/builders/llvm-gcc-i386-linux-selfhost/builds/208 (2) http://lab.llvm.org:8011/builders/dragonegg-i386-linux/builds/194 (3) http://lab.llvm.org:8011/builders/dragonegg-x86_64-linux/builds/197 The odd thing is that I can't see any suspicious
