[Sdcc-user] Multiplication problems on SDCC for PICs

[Vik O. <vi...@di...>]

I'm using this on a Debian box:

SDCC : mcs51/gbz80/z80/avr/ds390/pic16/pic14/TININative/xa51/ds400/hc08
2.5.0 #1020 (Sep  1 2005) (UNIX)

I can compile code for PIC16F628(A)s and make PICs run stepper motors
etc.

All works reasonably well until I try using a multiply (*) operation.

Something like:

	a*=5;

where 'a' is an unsigned int appears to be completely ignored, and does
not even generate a commented line in the .asm output. I do see the
message:

vik@chrysler:~/src/pic/comcenb$ sdcc --debug -mpic14 -p16f628 comcenb2.c
Processor: 16f628
checking for native mult
message: using default linker script "/usr/share/gputils/lkr/16f628.lkr"
vik@chrysler:~/src/pic/comcenb$

Any ideas how to work around this one?

Vik :v)
