Hello,
I have some problem with msp-gcc (version 4.6.1, mspgcc-20111224). When
I try to generate assembly code from this lines bellow:
x = advalue * cfg.ref_mv;
point = div32768(x);
it produces something like that:
mov r15, &__MPYS
mov &cfg+20, &__OP2
mov &__RESLO, r14
pop r2
mov r14, r15
swpb r15
sxt r15
swpb r15
sxt r15
call #div32768
Which is wrong for me as it discards high word from result (RESHI is not
copied, instead it is used an sign extension). Routine div32768 accepts
32bit signed integer.
Is there any switch for compiler to avoid this problem?
