Re: Weird issues. Linker + arm/thumb interworking / stub is not implemented.

Hi, 

Yes, with 2.16.1, -mthumb-interwork is fine.

Though, something still weird with binutils 2.15, or maybe my toolchain:

linker is called thought gcc, with:
arm-linux-ld -dynamic-linker /lib/ld-linux.so.2 -X -m armelf_linux -p
-o _a.out /usr/local/arm-linux/lib/gcc-lib/arm-linux/3.2.1/../../../../arm-linux/lib/crt1.o
/usr/local/arm-linux/lib/gcc-lib/arm-linux/3.2.1/../../../../arm-linux/lib/crti.o
/usr/local/arm-linux/lib/gcc-lib/arm-linux/3.2.1/crtbegin.o
-L/usr/local/arm-linux/lib/gcc-lib/arm-linux/3.2.1
-L/usr/local/arm-linux/lib/gcc-lib/arm-linux/3.2.1/../../../../arm-linux/lib
_arm.o _thumb.o -lgcc -lgcc_eh -lc -lgcc -lgcc_eh
/usr/local/arm-linux/lib/gcc-lib/arm-linux/3.2.1/crtend.o
/usr/local/arm-linux/lib/gcc-lib/arm-linux/3.2.1/../../../../arm-linux/lib/crtn.o

if I just do:
arm-linux-ld -dynamic-linker /lib/ld.so.-mthumb-interwork _arm.o _thumb.o  
has actually implemented the interworking!

I am not trying to investigate anymore since binutils 2.16.1 is ok,
Thanks you,

Sylvain
 
//sorry: it's not the version of gcc I said, but it was the same with
another toolchain
