This is the text of bug 3468951 reported on the SourceForge website:
"Some obsolete stuff in z80sim port," (submitted by Philipp Klaus Krause):
The simz80 port needs a few updates to work well with current sdcc versions,
and has some unecessary stuff:
* The linker name for Make.defs should be sdldz80
* The assembler name for Make.defs should be sdasz80
* _asm and _endasm in z80_io.c and z80_irq.c should be replaced by __asm
and __endasm
* The --stack-auto --int-long-reent --float-reent options or Make.defs should
be removed, as they have no effect on sdcc's z80 port
* The current assembler AFAIK can handle long symbol names, so the
sdcc-2.6.0-asz80-symlen.patch is unnecessary, and it and the corresponding
section from the README can be removed.
These changes have not yet been incorporated or verified.
