Not having much luck regression testing this one. Revision 148492 and 148493
both fail to bootstrap on x86_64-apple-darwin.

------- Comment #5 from howarth at nitro dot med dot uc dot edu  2009-12-16 13:58 -------
Any suggestions on how we can debug this issue further on darwin? Would this
bug indicate that we are missing some section of a previous patch addressing
mangling for the darwin target?

It seems like you're getting the right warning message, just on a different
line than expected.  I guess Rafael's checkin changed when the warning is
emitted on targets that support COMDAT groups, but not on other targets.

Shouldn't darwin have support for comdat? This patch, which went into FSF gcc
ages ago, suggests so...

------- Comment #8 from howarth at nitro dot med dot uc dot edu  2009-12-16 20:29 -------
What's up with the instantiation portions of the warning messages in darwin? On
Fedora 10, gcc trunk shows...

~/dist/bin/g++ mangle11.C -nostdinc++ -fmessage-length=0 -Wabi -fabi-version=1
-S -o mangle11.s
mangle11.C:10:24: warning: the mangled name of ‘void f(typename Q::X) [with Q =
S, typename Q::X = int]’ will change in a future version of GCC

whereas on darwin with gcc-4..4.2 we get...

g++-4 mangle11.C -nostdinc++ -fmessage-length=0 -Wabi -fabi-version=1 -S -o
mangle11.s
mangle11.C: In instantiation of ‘void f(typename Q::X) [with Q = S]’:
mangle11.C:10:   instantiated from here
mangle11.C:4: warning: the mangled name of ‘void f(typename Q::X) [with Q = S]’
will change in a future version of GCC

which is exactly what I see with g++-4.3.2 on Fedora 10.

g++ mangle11.C -nostdinc++ -fmessage-length=0 -Wabi -fabi-version=1 -S -o
mangle11.s

So I assume darwin is the only target that uses 'a poor man's comdat group'
rather than a real one? I don't see any other targets failing these tests.

[espindola at gcc dot gnu dot org]

------- Comment #10 from espindola at gcc dot gnu dot org  2009-12-17 18:09 -------
I tried to build gcc on darwin to debug this but the build fails with a link
failure (sorry, don't remember exactly where). Do I need to do something
special to build on darwin?

The error message is emitted when mangling the names and the "instantiated
from" bits use input_location. Yes, that is bad :-(

I assume that the difference is coming from use computing the assembler name at
a different point in time when building on darwin.

The short term "fix" might be to force the assembler name computation to happen
at a fixed point in time for both darwin and non-darwin systems.

The correct fix would be to not use input_location.

On which version of darwin did you try the build? Where were the gmp/mpfr/mpc
libraries? Do you remember the configure command?

Did you ever sort out your gcc build problems on darwin? Which darwin release
are
you building on?

This is a dup of c++/42748, which has now been fixed.

So marking this pr as duplicate.
