I appologize if I'm misunderstanding something about the code that is
being produced, but while auditing some code to try to make some code
smaller I noticed that __udivmodqi4 is being called twice to generate
code for:
unsigned char a, b, c;
c = some_input_function();
LABEL:
a = c/10;
b = c%10;
...
*****************************************
LABEL:
mov r24,r18
ldi r22,lo8(10)
call __udivmodqi4
mov r19,r24
.LM436:
mov r24,r18
call __udivmodqi4
If I'm understanding __udivmodqi4 it produces the results of both of
these with one call.
My compile command is:
avr-gcc -S -mmcu=atmega128 -Os -fno-delete-null-pointer-checks -Wall
-Wstrict-prototypes -Wa,-ahlms=gekv2c.lst -DETHERNUT2 -D__HARVARD_ARCH__
-gdwarf-2 -IC:/ethernut-4.4.0/nut/include file.c -o file.s
And as the -I tells, this is on Windows. The GCC version is 3.4.6 .
I do not subscribe to this list, so please CC me on any replies.
