[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?
Regards,
Won

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

[LLVMdev] [ARM backend] adding pattern for SMLALBB
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 :-

Hello

This is binutils bug fixed ~2 years ago:

Make sure you're using the latest binutils for ARM (from binutils CVS)

[LLVMdev] build errors while cross compiling llvm-gcc for ARM
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

[LLVMdev] Selfhost LLVM and Clang on ARM
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

[LLVM] Infinite loop during LLVM InstructionCombining pass optimization
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

Regular Expressions
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

Multinomial Logit and p-values
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,
