            Bug ID: 65306
           Summary: make error with clang on OSX 10.9.5 -- movq
           Product: gcc
           Version: 4.9.2
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: libgcc
          Assignee: unassigned at gcc dot gnu.org
          Reporter: research at matthewniemerg dot com

I am trying to compile gcc 4.9.2, downloaded from an ftp mirror, using my Mac's
native clang compiler.  My OS is OSX 10.9.5.

The following is the output from gcc -v and g++ -v.

gcc - v

Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr
--with-gxx-include-dir=/usr/include/c++/4.2.1
Apple LLVM version 6.0 (clang-600.0.56) (based on LLVM 3.5svn)
Target: x86_64-apple-darwin13.4.0
Thread model: posix


g++ -v

Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr
--with-gxx-include-dir=/usr/include/c++/4.2.1
Apple LLVM version 6.0 (clang-600.0.56) (based on LLVM 3.5svn)
Target: x86_64-apple-darwin13.4.0
Thread model: posix

I run into the following error when I run make after using the following for my
configure.


../gcc-4.9.2/configure --prefix=/usr/local/gcc/4.9.2 --enable-threads
--enable-static

Please note that I am creating the build directory not in the source directory
and not as a subdirectory of the source directory, i.e. directory structure is

--parent
gcc-4.9.2
gcc-4.9.2.build

This appears to be similar (although not the same) to Bug libgcc/56656 .

--- Comment #1 from Maxim Kuvyrkov <mkuvyrkov at gcc dot gnu.org> ---
Apple ships clang compiler in its recent versions of OS X, and it aliases "gcc"
to it.  You are not, in fact, using GCC, so please file bugs in clang's
bugzilla at http://llvm.org/bugs/ .

Thank you.

--- Comment #2 from Matthew Niemerg <research at matthewniemerg dot com> ---
I understand I am using clang as the compiler.  I am trying to build gcc-4.9.2
with clang as my compiler.

I have successfully used clang for compiling gcc-4.3.3, gcc-4.4.3, gcc-4.7.3,
and gcc-4.8.4 from source but am now trying to compile with clang for gcc-4.9.2
and this fails as indicated in the original report, hence why I filed the bug
report here.

I will also submit this bug report to their bugzilla.  

Thank you.

Oh, I'm sorry, I had a knee-jerk reaction.

Now that I have /actually/ read through your report ...

What assembler are you using?

To troubleshoot this please provide preprocessed source and final assembly. 
You can get these by adding "-save-temps" to the compilation command and
looking for *.i and *.s files.

--- Comment #4 from Matthew Niemerg <research at matthewniemerg dot com> ---
Don't worry about it.

The assembler I am using is

Apple Inc version cctools-862, GNU assembler version 1.38

(from as -v)

So, if I want to get the *.i and *.s files I should add "-save-temps" to say,
CPPFLAGS, when I do configure?

i.e., modifying my original configure to something like

../gcc-4.9.2/configure --prefix=/usr/local/gcc/4.9.2 --enable-threads
--enable-static CPPFLAGS="-save-temps" 

Thanks,
Matt

No need to rebuild the whole GCC with -save-temps.  Just go to directory where
compilation of extenddftf2_s.o takes place and copy-paste the compilation
command for that one file with addition of -save-temps.

I'm not familiar with "Apple Inc version cctools-862, GNU assembler version
1.38", so it may be that assembler is broken or too old; you may have to build
recent binutils for your GCC to use.

--- Comment #6 from howarth at bromo dot med.uc.edu ---
I don't see this problem with the same Xcode 6.1.1 and associated command line
tools package installed on 10.9.4 as current gcc-4_9_branch...

% ../gcc-4.9.3-20150227/configure --prefix=/Users/howarth/dist
--enable-languages=c,c++ --with-gmp=/sw --with-libiconv-prefix=/sw
--with-isl=/sw --with-cloog=/sw --with-mpc=/sw --with-system-zlib
--x-includes=/usr/X11R6/include --x-libraries=/usr/X11R6/lib --enable-threads
--enable-static

bootstraps fine here. The fact that you aren't aren't using -with-gmp or
--with-mpc is rather disconcerting as it suggests you have been installing into
the system directories instead of /usr/local or /opt. If so, I would suggest
reinstalling the OS to purge out anything you've installed in the system
directories.

@Max.  See the attached files.

@Howarth.  I am compiling gcc-4.9.2 with gmp, mpfr, and mpc source directories
in the gcc-4.9.2 source tree.  There is nothing disconcerting about not passing
--with-* to the configure script, as per the directions found on
https://gcc.gnu.org/install/configure.html .

Kind regards,
Matt

--- Comment #10 from Uroš Bizjak <ubizjak at gmail dot com> ---
Assembler support for interunit movq (e.g. "movq %rax, %xmm0") is detected with
configure, and HAVE_AS_IX86_INTERUNIT_MOVQ flag is set accordingly.

It looks that configure checks different assembler than the one used to compile
the library.

I see no problems here on darwin13.4.0 (with mpc-1.0.2, gmp-6.0.0a, mpfr-3.1.2,
isl-0.12.2 and cloog-0.18.2 present in the gcc-4_9-branch svn tree as mpc, gmp,
mpfr, isl and cloog) using...

cd work
../gcc-4.9.3-20150227/configure --prefix=/Users/howarth/dist
--enable-languages=c,c++ --with-system-zlib --x-includes=/usr/X11R6/include
--x-libraries=/usr/X11R6/lib --enable-threads --enable-static
make -j8 bootstrap

The in-tree bootstrap completes without errors.
