I'm getting the following assembler error with current gcc 4.3. This
worked with 20070604 and is probably due to the dataflow merge.
tbm@coconut0:~$ /usr/lib/gcc-snapshot/bin/gcc -c -O1 ccmalloc-callchain.c
ccmalloc-callchain.c: In function 'backtrace':
ccmalloc-callchain.c:14: warning: unsupported argument to
'__builtin_return_address'

static jmp_buf backtrace_jump;
static char *
return_address (unsigned i)
{
switch (i)
{
case 0:
return (char *) __builtin_return_address (0);
case 1:
return (char *) __builtin_return_address (1);
}
}
backtrace (int skip)
{
if (_setjmp (backtrace_jump) == 0)
{
int i = ++skip;
while (1)
{
char *pc = return_address (i++);
if (!pc)
break;
}
}
}

------- Comment #1 from jakub at gcc dot gnu dot org 2007-07-04 16:35 -------
Created an attachment (id=13846)
--> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=13846&action=view)
gcc43-pr32337.patch
The problem seems to be caused by the addition of the
emitted_frame_related_regs
array, there are several issues I found (see this patch) and in the end
two of the 3 saved registers (RP, PFS, FP) were saved in the same register,
which caused severe havoc.
I'll try to bootstrap/regtest this on ia64-linux, so far I have only tested
that it cures the testcase.
