Yes, most likely.  Could you post the contents of the 'asm' specs and its
children (on Solaris it's asm -> asm_cpu -> asm_cpu_default)?

Unless I'm mistaken, I see no smoking gun.  Could you post the line passed to
the assembler by the driver (with -v)?  Are you sure the command line passed to
the driver contains no other relevant bits?

I don't think so.  GCC on sparc64-*-linux is supposed to default to
-mcpu=ultrasparc if no -mcpu= is given.

The problem was reported against gcc version 3.4.1 20040611 so your patch was
very likely in the compiler.

I see -mcpu=v9 passed to cc1, which means that the driver probably sees it too,
so passes -Av9 as per the asm_cpu specs.  It could come from a --with-cpu=v9 on
the configure line, but I don't see it in the output of 'gcc -v'.

Pawe?, did you apply local patches to the FSF sources?

It is actually automatically set by the configure script:

	sparc*-*-*)
		# Some standard aliases.
		case x$with_cpu in
		xsparc)
			with_cpu=v7
			;;
		xsparc86x)
			with_cpu=sparclite86x
			;;
		xsparcv9 | xsparc64)
			with_cpu=v9
			;;
		esac

Jakub, how is your sparc64-redhat-linux compiler supposed to work?  I see you
configured it with --with-cpu=v7, so the driver will append -mcpu=v7 to the
command line if there is no -mcpu, right?  How do you turn that into
-mcpu=ultrasparc?

------- Additional Comments From jakub at gcc dot gnu dot org  2004-07-08 18:27 -------
If the compiler is configured with --with-cpu=v7, then it defaults to -m32.
#define OPTION_DEFAULT_SPECS \
  {"cpu", "%{!m64:%{!mcpu=*:-mcpu=%(VALUE)}}" }, \
...
means that -mcpu=v7 will be passed if no -mcpu is given AND -m64 is not present
on the command line.  If -m64 is present and -mcpu is not given, CC1_SPEC
will add -mcpu=ultrasparc.
Similarly for a compiler defaulting to -m64.
BTW, the compiler is misconfigured, it ought to use --libdir /usr/lib on sparc64,
not /usr/lib64.

This one I've always found strange, but now I see how it works.  It's different
on Solaris, because sol2-64.h unconditionally sets MASK_64BIT in TARGET_DEFAULT.

Aaaaah!  I should have grasped that when you posted the OPTION_DEFAULT_SPECS
patch for Linux.  We have the "-m64 doesn't shut down -mcpu=v7" problem on
Solaris in 3.4.x (PR target/16416) so I'm going to shamelessly steal your patch.

Thanks for the explanation.


[About the original problem:]
It seems to me that the flags are missing on the line:

  sparc64-pld-linux-gcc ../sysdeps/sparc/sparc64/memset.S [...]
