Description Alexandru Georgescu 2012-09-11 11:30:32 UTC 
The assembler installed by the toolchain is not loaded when the environment is sourced and the host assembler is used instead causing some erorrs.

************************************
HAPPENS ON:
Fedora 17 (and CentOS) for: 
poky-eglibc-x86_64-arm, poky-eglibc-x86_64-mips, poky-eglibc-x86_64-powerpc

Ubuntu 12.04 for: 
poky-eglibc-x86_64-mips, poky-eglibc-x86_64-powerpc

Please note that poky-eglibc-x86_64-arm on Ubuntu doesn't reproduce.


************************************
STEPS TO REPRODUCE (for ARM in Fedora):
1. Download and install the arm toolchain: http://autobuilder.yoctoproject.org/pub/nightly/20120910-5/toolchain/x86_64/poky-eglibc-x86_64-arm-toolchain-gmae-1.2+snapshot-20120911.sh

*************************************
2. source the environment

*************************************
3. Create the following C file:

alex@alex-pc:~/_current$ cat test.c 
#include <stdio.h>
#include <math.h>

double
convert(long long l)
{
   return (double)l;    // or double(l)
}

int
main(int argc, char * argv[])
{
   long long l = 10;
   double f;

   f = convert(l);
   printf("convert: %lld => %f\n", l, f);

   f = 1234.67;
   printf("floorf(%f) = %f\n", f, floorf(f));
   return 0;
}
alex@alex-pc:~/_current$ 


********************************************
4. Compile the following C file:
[alex@alex-v compile]$ ${CC} test.c -o  test -lm
Assembler messages:
Fatal error: invalid -march= option: `armv5te'
[alex@alex-v compile]$


*********************************************
5. Compile in verbose mode:

[alex@alex-v compile]$ ${CC} -v test.c -o  test -lm
Using built-in specs.

**************************************
OTHER COMMENTS:
As you can see in the verbose output in step 5, the host compiler is used instead of the toolchain compiler:

 as -v -march=armv5te -mthumb-interwork -mfloat-abi=soft -meabi=5 -o /tmp/cc5cqxcM.o /tmp/ccku8YtF.s

Comment 1 liang li 2012-09-13 02:14:00 UTC 
the error not met in my test host (ubuntu 12.04 and fedora 17) with the same toolchain of nightly build 20120910-5.

That's strange. We managed to reproduce on 4 different machines: Two Fedora 17, one Ubuntu and one Cent OS.

Bogdan, can you try to reproduce in your machine?

Thanks,
Alex.
Comment 3 Richard Purdie 2012-09-13 14:50:02 UTC 
This looks like it might be a relocation issue with the toolchain
Comment 4 Radu Moisan 2012-09-20 09:37:38 UTC

Confirmed to be a relocation issue. Laurentiu is preparing a patch. Assigning to Laurentiu.
Comment 5 Laurentiu Palcu 2012-09-20 13:55:00 UTC 
The symlinks to the toolchain binaries in usr/libexec directory were not relocated. Fixed the issue, patches were sent on the mailing list for review.
