Speex dev - Apr 2007 - Info on Symbian, ARM and OFFSET_IMM8 relocation error

Hi all,

i'm using speex under symbian.
When i have compiled the lib for ARM platform i have obtained the follow error:

"Error: Can not represent OFFSET_IMM8 relocation in
this object file format (1)"

I have defined FIXED_POINT 1 and ARM4_ASM.

The error is in the function forced_pitch_quant contained in ltp.c.

The line that produce the error is:
target[i]=EXTRACT16(SATURATE(SUB32(EXTEND32(target[i]),EXTEND32(res[i])),32700));

Why this error??? In the emulator i have no problem.

I resolved with the sequent workaround:

spx_word16_t tmp EXTRACT16(SATURATE(SUB32(EXTEND32(target[i]),EXTEND32(res[i])),
32700));
target[i] = tmp;

Now i can compile e linking the lib in my application.

Hi,

What you pasted below looks like a compiler bug to me, especially
considering the workaround you use. Just curious, does the problem still
happen if you disable ARM4_ASM?

No, the problem is absent with ARM4_ASM disabled.

Another error that I have with ARM and ASM is in the override
functions inner_prod and pitch_xcorr defined in ltp_arm4.h. The error
is "more than 10 operands in 'asm'".
I have resolved with no inclusion of the that header file in ltp.c.
