Recent regression & configuring ppc simulator

Recent regression & configuring ppc simulator

[John Wehle]

I'm looking into the gcc.c-torture/execute/950511-1.c regression
and need a little help configuring the ppc simulator.  I've
configured and built binutils 2.10, gcc, and gdb 5.0 using

  --target=powerpc-eabisim

on a x86 FreeBSD 3.5 host. When I try to compile a simple program
I get:

  /usr/local/powerpc-eabisim/bin/ld: unrecognised emulation mode: elf32ppcsim
  Supported emulations: elf32ppc
  collect2: ld returned 1 exit status

Suggestions?

What files are in /usr/local/powerpc-eabisim/powerpc-eabisim/lib/ldscripts?

I just built a CVS snapshot from today using:

  $ ../binutils-20000911/configure --host=i586-redhat6-linux-gnu	\
	--target=powerpc-eabisim --build=i586-redhat6-linux-gnu		\
	--srcdir=../binutils-20000911 --prefix=/opt/gnu			\
	--exec-prefix=/opt/gnu/H-ia32-linux				\
	--enable-targets=powerpc-eabisim --enable-shared=no

and I have the elf32ppcsim.x* files in my ldscripts directory now. Perhaps,
you should use CVS sources, too.

HTH, cheers.

You need to use CVS binutils with CVS gcc for powerpc embedded
targets.

[See also my message to gcc-patches about this regression, though,
which may save you debugging time.  Perhaps you can come up with a
better patch than the one I've applied.]

Sure do.

Thanks.  BTW, who supplies abort ... do I need newlib?

I've followed up in a separate email to CC gcc-patches.
