[Sdcc-user] -nostdlib, __mulsint_rrx_s

[Stefan R. <do...@dr...>]

Hi,

sorry for posting two questions/bugs at once... I actually wanted to 
report yet another bug (broken right shift operator), but I discovered 
it has been solved in the latest snapshots :-)

So here come today's bugs:

1. -nostdlib seems to be slightly broken in current snapshots. I had 
been using a snapshot from Feb 03 and switched to today's snapshot 
(20030726). If I compile my program with this command:

    sdcc -mz80 --nostdlib --code-loc 0x0400 --data-loc 0x5000 mysrc.c

I suddenly get: "Warning: couldn't find crt0.o". With the Feb 03 
snapshot, this didn't happen.

2. When I multiply ints ( int a, b, c; a = b*c; ), I get the message:

    ?ASlink-Warning-Undefined Global __mulsint_rrx_s referenced by 
module temp

It seems mulsint_rrx_s isn't defined in the sdcc libraries; I only found 
mulint_rrx_s in lib/src/z80/mul.s.
