[Bug fortran/34025] New: Warning when compiling with -m64 -ffast-math on Intel Darwin

[dominiq at lps dot ens dot fr]

When compiling any fortran program on Intel Darwin with -m64 -ffast-math, I get
the following warning:

ld64 warning: in
/opt/gcc/gcc4.3w/lib/gcc/i686-apple-darwin8/4.3.0/x86_64/crtfastmath.o, file is
not of required architecture

This yields the failure of gfortran.dg/pr32533.f90 and gfortran.dg/pr33794.f90.

Can you get the same warning with a C program? And can you please post the
output of running gfortran with -v, so that we know what subprocesses are
invoked and what arguments they get passed?

Hmmm, this should have been compiled with -m64.  Can you attach your build log

------- Comment #7 from howarth at nitro dot med dot uc dot edu  2007-12-15 21:35 -------
I find the following works here...

cd /sw/src/fink.build/gcc43-4.2.999-20071214/darwin_objdir/gcc
./xgcc -m64 -B./ -B/sw/lib/gcc4.3/i686-apple-darwin9/bin/ -isystem

-DIN_GCC -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes
-Wold-style-definition -isystem ./include -fPIC -pipe -g -DHAVE_GTHR_DEFAULT
-DIN_LIBGCC2 -D__GCC_FLOAT_NOT_NEEDED -msse -minline-all-stringops -c
../../gcc-4.3-20071214/gcc/config/i386/crtfastmath.c -o x86_64/crtfastmath.o

This eliminates the failures in make check at -m64. I wonder if we really
shouldn't be using lines like...

EXTRA_MULTILIB_PARTS=crtbegin.o crtend.o crtbeginS.o crtendS.o \
                     crtbeginT.o crtprec32.o crtprec64.o crtprec80.o \
                     crtfastmath.o

from gcc/config/i386/t-linux64 for t-darwin? On x86-64 linux, a build of gcc
trunk properly creates the correct architecture of crtfastmath.o in the 32
subdirectory. Or alternatively maybe it would be sufficient to just add
crtfastmath.o to the line...

# How to build crt3.o
EXTRA_MULTILIB_PARTS=crt3.o

in gcc/config/t-darwin since that seems to properly build the correct
architecture of crt3.o for the x86_64 subdirectory on i686-apple-darwin9.

For some reason the last change isn't forcing the MULTILIB_CFLAGS to actually
be used on the build lines for the objects added to EXTRA_MULTILIB_PARTS.

# Recursively invoke make in the GCC directory to build any
# startfiles (for now).  We must do this just once, passing
# it all the GCC_EXTRA_PARTS as simultaneous goal targets,
# so that rules which cannot execute simultaneously are properly
# serialized.  We indirect through T_TARGET in case any multilib
# directories contain an equals sign, to prevent make from
# interpreting any of the goals as variable assignments.
# We must use cd && make rather than make -C, or else the stage
# number will be embedded in debug information.

[Bug target/34025] Warning when compiling with -m64 -ffast-math on Intel Darwin

[howarth at nitro dot med dot uc dot edu]

------- Comment #12 from howarth at nitro dot med dot uc dot edu  2007-12-16 01:13 -------
I can't help but wonder if this issue is due to the fact that darwin is the
only architecture that uses a single value for MULTILIB_OPTIONS. We only
have...

MULTILIB_OPTIONS = m64

whereas all the other architectures seem to have something like...

MULTILIB_OPTIONS = m64/m32

I'll take a stab at changing this to...

MULTILIB_OPTIONS = m32/m64

The last change just creates an endless loop in the build.

------- Comment #15 from howarth at nitro dot med dot uc dot edu  2007-12-16 05:44 -------
The problem was that gcc/config/i386/t-crtpc  and
gcc/config/i386/t-crtfm had build commands which
didn't use MULTILIB_CFLAGS. Now that those are added
all of the object files in the x86_64 subdirectory are
of the proper architecture.
