similar to: [LLVMdev] ARM cross compiling causes segmentation fault

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?

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

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, 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, all I am trying to selfhost LLVM and Clanf on ARM. Hopefully doing this can reveal what version of GCC is broken. But I have a concern about the following message while building LLVM and Clang by using clang (selfhost build). --- llvm[1]: Compiling DeltaAlgorithm.cpp for Debug build /tmp/cc-DqWGS1.s: Assembler messages: /tmp/cc-DqWGS1.s:8963: Rd and Rm should be different in mul llvm[1]:

I'm getting following errors while cross compiling llvm for ARM. Please help since it is urgent and critical My gcc version is 4.2.0, 32bit Linux and target is ARM Configure options are: ./configure --host=i686-pc-linux-gnu --build=i686-pc-linux-gnu --target=armv7fl-montavista-linux-gnueabi --enable-cross --with-sysroot=/home//arm_v7_vfp_le/target/

Bug #4521 has been filed. traps.c has been also attached.

Hello, While I was trying to cross-compile Linux OMAP kernel with llvm, I have the following error message. CC arch/arm/kernel/traps.o cc1: /home/wonjeon/llvm/lib/CodeGen/SelectionDAG/SelectionDAGBuild.cpp:5388: void llvm::SelectionDAGLowering::visitInlineAsm(llvm::CallSite): Assertion `(OpInfo.ConstraintType == TargetLowering::C_RegisterClass || OpInfo.ConstraintType ==

If you're able to reproduce the infinite loop with -O3 then you should be able to dump out the IR that causes `opt -instcombine` to infloop, unless the bug is truly esoteric (e.g. only caused by a specific use-list ordering). Maybe take a closer look at the output from `opt -print-before-all -O3`? Alternatively you can use bugpoint to minimize the IR to get a small reproducer that causes

Thanks for the bug report. The attached file isn't helpful for reproducing the problem. I don't have all the header files that are included, so I can't just try to run it through my version of llvm-gcc and see what happens. At a minimum, please attach the preprocessed source file along with the complete llvm-gcc command line that you used to compile it. That would

traps.i has been attached. I used 'make CROSS_COMPILE=llvm-arm-' to compile the kernel with default configurations provided by kernel package If you need more information, please let me know.

Hi, Is there a way to use regular expressions to capture two or more words in a sentence? For example, I wish to to find all the lines that have the words "thomas", "perl", and "program", such as "thomas uses a program called perl", or "perl is a program that thomas uses", etc. I'm sure this is a very easy task, I would greatly appreciate

Hi, I am trying to obtain p-values for coefficient estimates in a multinomial logit model. Although I am able to test for significance using other methods (e.g., Wald statistics), I can't seem to get R to give me simple p-values. I am sure there is a very simple solution to this, but the R archives seem to have nothing on this issue. I would appreciate any help. Thanks in advance! Best,
