[Bug bootstrap/28326] New: [4.1/ICE] gcc-4.1.0 won't compile on power3

[Bug bootstrap/28326] New: [4.1/ICE] gcc-4.1.0 won't compile on power3

[markus at unixforces dot net]

If I try to bootstrap on ppc64 and try to use BOOT_CFLAGS="-m64 -O2
-pipe -mtune=power3 -mcpu=power3" I get an ICE. If I leave out "-mtune=power3
-mcpu=power3" the bootstrap finishes. So one of the optimizations is causing
this.

here are the steps I followed some while ago. see
http://bugs.gentoo.org/show_bug.cgi?id=126960 (gcc 4.1.1 has the same result)

Can you try without STAGE1_CFLAGS="-O"?
And can you try bootstrap instead of profiledbootstrap ?

and this:
$ make LDFLAGS="" LIBPATH="/usr/lib/gcc/powerpc64-unknown-linux-gnu/4.1.1"
BOOT_CFLAGS="-m64 -O2 -pipe -mtune=power3 -mcpu=power3" bootstrap

last command builds fine. this is a regression then? gcc-3.4 used to build fine
using profiledbootstrap. I have not tried gcc 4.0 IIRC.

[Bug bootstrap/28326] [4.1 regression] profiledbootstrap will produce an ICE with "-mtune=power3 -mcpu=power3" in BOOT_CFLAGS

[markus at unixforces dot net]

------- Comment #3 from markus at unixforces dot net  2006-07-11 20:17 -------
I did some testing and this are the results:

gcc versions 3.4.6, 4.0.3 and 4.2-20060708 do all _not_ fail with
profiledbootstrap and "-mtune=power3 -mcpu=power3" in BOOT_CFLAGS.

which information do you need to get this fixed?

*.s asm file, produced by adding -save-temps to the compile flags (Comment #0)
for _muldi.o compile. A skilled ppc person can check failed asm instruction and
eventually fix assembler template of the insn description.

However, gcc-4.1 is a bit old now...

I'm marking this bug as WONTFIX then.
