[Gumstix-users] Assembler messages: bad instruction

From: James Bond <gumstix007@gm...> - 2007-10-01 02:57

Hi all,

I am trying to port my program to gumstix. However, when I compile it,
I get some errors that are related to assembly instructions and
reported by assembler. Below are the error messages:

gumstix007@...$ make
/home/gumstix007/gumstix-serial/../gumstix-buildroot/build_arm_nofpu/staging_dir/bin/arm-linux-uclibc-gcc
-O2 -I/usr/include/libxml2 -I/usr/include  -M testbed-demo.c > .depend

-O2 -I/usr/include/libxml2 -I/usr/include  -Os -march=armv5te
-mtune=xscale -Wa,-mcpu=xscale -c -o testbed-demo.o testbed-demo.c
/tmp/ccMaucR8.s: Assembler messages:
/tmp/ccMaucR8.s:2218: Error: bad instruction `btsl r2,[r3,#-1152]'
/tmp/ccMaucR8.s:2778: Error: bad instruction `btsl r2,[r3,#-128]'
make: *** [testbed-demo.o] Error 1

Does anyone have an idea about what the problem is? Any reply will be
welcome. Thanks!

James

P.S. My GCC version is 4.1.2

BTSL seems to be a x86 instruction, not a ARM (or thumb) one. I have
no idea what the file ccMaucR8.s is and why the instruction is there.

Forgive me if i'm wrong, but your include paths look like they're for 
your host machine rather than within the buildroot.
