[Bug boehm-gc/30327] New: The make script periodically thinks my 7450 is an 8540

[trog24 at comcast dot net]

The system is a Dual 800 MHz PowerPC G4 (7450) (QuickSilver) running under
Darwin 8.8.0. 

The command sequence is as follows:

 cd gcc
 mkdir build
 cd build
 ../configure
 make >make.log

Periodically, the following appears:

 ../../gcc/config/rs6000/altivec.md:xxx: warning" operand 3 missing mode?

I am assuming that the rs6000 has the same altivec as the 74xx series.

Periodically, the following also apppears:

 Links are now set up to build a native compiler for powerpc-apple-darwin8.8.0.

Also, there were the following automatons:

Automaton `ppc7450fp'
       36 NDFA states,             75 NDFA arcs
       36 DFA states,              75 DFA arcs
       36 minimal DFA states,      75 minimal DFA arcs
      462 all insns          5 insn equivalence classes
    0 locked states
   76 transition comb vector els,   180 trans table els: use simple vect
  180 min delay table els, compression factor 1

Automaton `ppc8540_retire'
      162 NDFA states,            876 NDFA arcs
      162 DFA states,             876 DFA arcs
       81 minimal DFA states,     438 minimal DFA arcs
      462 all insns          8 insn equivalence classes
    0 locked states
  509 transition comb vector els,   648 trans table els: use simple vect
  648 min delay table els, compression factor 2

After several hours, the following appeared:

 mkdir ppc64

later to be followed by:

 checking whether c compiler works...
 configure: error: cannot run C compiled programs.
 If you meant to cross compile use '--host'.
 See 'config.log' for more details.
 make[1]: *** [configure-target-boehm-gc] error 1
 make: *** [all] Error 2

~/gcc/build/powerpc-apple-darwin8.8.0/ppc64/boehm-gc/configure.log is as
follows:

configure:2346: checking whether the C compiler works
configure:2352: ./a.out
../../../../boehm-gc/configure: line 1: ./a.out: Bad CPU type in executable
configure:2355: $? = 126
configure:2364: error: cannot run C compiled programs.
If you meant to cross compile, use `--host'.
See `config.log' for more details.

which appears to indicate that an attempt was made to run an 8540 compiled
program on a 7450.

This happened twice.

Since you don't have a G5, you should do --disable-multilib.

I was able to make and install via --disable-multilib as suggested by pinskia
which reduces the problem to minor since a work around exists; however, the
multilib should be disabled automatically if gcc is not being installed as a
cross compiler.  I thank you for the assistance.

(In reply to comment #2)

The real problem behind this has already been fixed on the mainline.  It was an
automake issue.
