This how I have implemented inflate.asm in png lib:

register z_streamp instream __asm("a5");
register int flush __asm("a6");

int inflate_asm(register z_streamp instream __asm("a5") ,register int flush __asm("a6"));

int
png_zlib_inflate(png_structrp png_ptr, int flush)
{
...
   return  inflate_asm(&png_ptr->zstream, flush);
}

or

register int outdata __asm("a4");
register z_streamp instream __asm("a5");
register int flush __asm("a6");

int inflate_asm(register z_streamp instream __asm("a5"), register int outdata __asm("a4") ,register int flush __asm("a6"));

int
png_zlib_inflate(png_structrp png_ptr, int flush)
{

...

    inflate_asm(&png_ptr->zstream, outdata, flush);
	
   return  outdata;

}

None of this works, have I missed something ?
