--- Comment #1 from John David Anglin <danglin at gcc dot gnu.org> ---
The problem occurs in getting the start callinfo symbol used for the
parisc unwind data. The following hunk of code in gbc.c isn't quite
right:
#if defined(__hppa__) /* Courtesy of Lamont Jones */
/* the calling sequence */
struct regs {
void *callee_saves[16];
};
void hppa_save_regs(struct regs);
/* the code */
asm(".code");
asm(".export hppa_save_regs, entry");
asm(".label hppa_save_regs");
asm(".proc");
asm(".callinfo");
asm(".entry");
asm("stw %r3,0(%arg0)");
asm("stw %r4,4(%arg0)");
asm("stw %r5,8(%arg0)");
asm("stw %r6,12(%arg0)");
asm("stw %r7,16(%arg0)");
asm("stw %r8,20(%arg0)");
asm("stw %r9,24(%arg0)");
asm("stw %r10,28(%arg0)");
asm("stw %r11,32(%arg0)");
asm("stw %r12,36(%arg0)");
asm("stw %r13,40(%arg0)");
asm("stw %r14,44(%arg0)");
asm("stw %r15,48(%arg0)");
asm("stw %r16,52(%arg0)");
asm("stw %r17,56(%arg0)");
asm("bv 0(%rp)");
asm("stw %r18,60(%arg0)");
asm(".exit");
asm(".procend");
asm(".end");
#endif
The line "asm(".label hppa_save_regs");" should be before the .proc line.
As a result, gas finds the label marking the start of text in the object. It
doesn't seem to have a valid frag.
I think the above code has been the same for many years.
