Oh, -fpic on i686-darwin should be made equivlant to -fPIC without any warning.

The patch does not work for bootstapping and I don't have access to x86-darwin
to even try to start fixing this.

Hello,

I also have this problem, but it also gets triggered in the bootstrapping phase
for a cross-compiler.

This is while creating a compiling i686-linux -> i686-apple-darwin8
crosscompiler on Fedora Core 4; I consider this a major bug.

/home/hanwen/vc/gub/target/darwin-x86/src/gcc-4.1.0/libiberty/regex.c: In
function ‘byte_common_op_match_null_string_p’:
/home/hanwen/vc/gub/target/darwin-x86/src/gcc-4.1.0/libiberty/regex.c:7724:
error: unrecognizable insn:

/home/hanwen/vc/gub/target/darwin-x86/src/gcc-4.1.0/libiberty/regex.c:7652 (set

        (label_ref:SI 26)) -1 (nil)
    (insn_list:REG_LABEL 26 (nil)))
/home/hanwen/vc/gub/target/darwin-x86/src/gcc-4.1.0/libiberty/regex.c:7724:

Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.


This was triggered by compiling with the following configure flags. If
necessary, I can send a CPP output file.

--prefix=/home/hanwen/vc/gub/target/darwin-x86/install/gcc-root/usr
--program-prefix=i686-apple-darwin8-

BTW, why not look at apple's solution to this problem?  GCC 4.0 has the same
problem, but the version that apple ships doesn't exhibit it.

Apple's config.h is at

Because it just disables -fpic, I have a patch which fixes this and I am about
to commit it.
