Hi again.

The instruction is iflush in /usr/libexec/ld.so compiled from
gnu/usr.bin/ld/sparc/md.c:

static __inline void /* Line 91 in md.c */
iflush(sp)
	jmpslot_t		*sp;
{
	__asm __volatile("iflush %0+0" : : "r" (sp));
	__asm __volatile("iflush %0+4" : : "r" (sp));
	__asm __volatile("iflush %0+8" : : "r" (sp));
}

I commented the assembler which gave me dynamic linked binaries that
do not dump core in /usr/libexec/ld.so. The question is if it is valid
to skip the iflush - or should I do something else instead ???? The
target machine is a Cypress 605 (see below).

Regards,
Harald.
