Bit of a corner case that came up when I was playing with one of the z88 apps:

#include <stdio.h>

int main()
{
        puts("Contact: xyz@da");
#asm
        defm    "Contact: xyz@dd"
#endasm
}

results in:

Code: Select all

        defm    "Contact:
        xyz@dd"
        ret
___str_0:
        DEFM "Contact: xyz@da"
        DEFB 0x00

The trigger seems to be the colon in assembly defm, I'm guessing it's tripping up over one of the sdcc peephole rules.

It's sdcc itself that's doing it even with the peepholer turned off. I'll have a look at the source and see if there's something there.

I'll just add the sdcc test case:

Code: Select all

extern int puts(const char *s);

int main()
{
        puts("Contact: xyz@da");
__asm
        .ascii "Contact: xyz@dd"
__endasm;

}

sdcc -mz80 -S --no-peep test.c

Code: Select all

_main::
;zz.c:6: puts("Contact: xyz@da");
        ld        hl,#___str_0
        push        hl
        call        _puts
        pop        af
;zz.c:9: __endasm;
                .ascii        "Contact:
        xyz@dd"
00101$:
        ret
___str_0:
        .ascii "Contact: xyz@da"
        .db 0x00

It's going to take someone more familiar with the sdcc lexer to fix:

They've fixed it already. An updated zsdcc.exe for windows can be found here:
