[Buildroot] libev on armv5 - illegal instruction

[Buildroot] libev on armv5 - illegal instruction

[Jan Pohanka]

Hello,

I'd like to use libev on my arm system with arm9 processor (armv5te).  
Unfortunately when I use libev-4.11 compiled by buildroot there is a  
problem with SIGILL illegal instruction. I checked the compiled library  
more deeply and there is really 'vldr' instruction which works only on  
cores with NEON.

I tried to compile the libev outside the buildroot with same CFLAGS  
(-march=armv5te -mcpu=arm926ej-s -mtune=arm926ej-s -mfloat-abi=softfp -Os)  
and cross-compiler (arm-2011.03 from codesourcery) and in this case the  
library works as expected.

When I set the path to BRROOT/output/host/bin and compile it there is the  
illegal instruction problem again. Even if the wrappers in host directory  
calls the same compiler.

Could please anyone give me some advice how to solve this problem? The  
rest of applications from buildroot works without any problems.

best regards
Jan

Could you post your Buildroot .config file?

Thanks!

[Buildroot] libev on armv5 - illegal instruction

[Jan Pohanka]

Hello,

> Could you post your Buildroot .config file?
It is pasted below...

Now I also discovered that the problem is machine specific. I have two
hosts using exactly the same cross-compiler and buildroot. One works and
the second one (my workstation) does not.

working host (Ubuntu 11.10) uname -a
Linux linux-dev 3.0.0-23-server #39-Ubuntu SMP Thu Jul 19 19:37:41 UTC
2012 x86_64 x86_64 x86_64 GNU/Linux

my workstation (Ubuntu 12.04 lts) uname -a
Linux pohanka-pc 3.2.0-27-generic #43-Ubuntu SMP Fri Jul 6 14:25:57 UTC
2012 x86_64 x86_64 x86_64 GNU/Linux

It is really weird. I cannot imagine how buildroot using the same
crosscompiler can produce different binaries on different PCs...

[Buildroot] libev on armv5 - illegal instruction

I have checked it once more with fresh git clones of BR and cross  
toolchain reinstalled.
config.log in output/build/libev-4.11 are the same on both machines as  
well as generated Makefiles (except of absolute paths to buildroot  
directory).

However the compiled binaries on both hosts are different. I have never  
seen that before.

The problem is in the function

ev_tstamp ev_time (void)
{
   struct timeval tv;
   gettimeofday (&tv, 0);
   return tv.tv_sec + tv.tv_usec * 1e-6;
}

where the computation uses vldr instruction. I was not succesful to  
simulate outside of libev...

regards
Jan

The toolchain is not downloaded by Buildroot in your .config. Are you
sure you have the same toolchain on both build machines?

Also, could you put online:

 - A complete build log on both machines (make clean && make)
 - The two binaries that are different and causing problems

Best regards,

Thomas

I have checked it again, yes toolchain are the same:
arm-2011.03-41-arm-none-linux-gnueabi-i686-pc-linux-gnu.tar.bz2 from
Codesourcery

> Also, could you put online:
>

Example and logs can be downloaded from  
http://neuron.feld.cvut.cz/honza/br_test.tar.bz2
Buildroot logs and example source and binaries libev libraries (working  
and not working) are statically linked
with testing application. Compiler is called through BR wrapper (in
BR_PATH/output/host/usr/bin)

You have ccache enabled. Can you try doing a build with ccache
disabled, and see if it generates a working libev?

Thanks!

Thank you for pointing this out. I didn't realized what ccache do and  
there was probably cached some version with wrong CFLAGS.
