Thanks to Andrew's code, Mike's and Geoff's comments in the PR, help
from Uros, Paolo and Jack, and Dominique's machine for testing, here is
a patch for fixing this PR. It has three independent parts, joined
together because I regtested them together:
1. the target part, in gcc/config/darwin* and gcc/config/rs6000, that
takes care of setting correct assembler names for the builtins, if needed
2. the Fortran front-end part, bordering on obvious, that makes
cpow{f,,l} builtins instead of simply considering them library functions
(otherwise, they don't benefit from the patch above)
3. the Fortran testsuite part, splitting testing of ERF/ERFC from
large_real_kind_2.F90 into its separate test case, which still fails on
Darwin at -O0 because Apple's PowerPC erfl() and ercl() are plain useless.
The patch was bootstrapped on powerpc-apple-darwin9.2.0 with C and
Fortran, and regtested with both -m32 and -m64 for these same languages.
OK for trunk? (I need a Darwin maintainer approval for the target stuff,
and a Fortran maintainer for Fortran parts.)
Fortran parts are OK. As an aside, this should also allow gfortran to
constant fold cpow* calls.
