[Bug bootstrap/22330] Building a cross linux->win32 incorrectly sets HAVE_GAS_SHF_MERGE true

[membar at gcc dot gnu dot org]

------- Comment #9 from membar at gcc dot gnu dot org  2005-11-04 06:41 -------
I was able to "fix" this issue with an explicit --with-as=<full path to
i686-pc-mingw32-as> and --with-ld=<full path to i686-pc-mingw32-ld>. The
crossed native compiler passes the testcase that Rutger sent me.

Note that the correct term for the compiler we're referring to is "x-host-x,
crossed native or crossed-built native" and not a Canadian cross. See

[Bug other/22330] New: Building a cross linux->win32 incorrectly sets HAVE_GAS_SHF_MERGE true

[ovidr at users dot sourceforge dot net]

gcc/gcc/java/class.c

if (HAVE_GAS_SHF_MERGE) should be false for windows target.  However,
it's definition is done by configure for _host_, and it ends up as true
in auto-host.h if you cross compile

[Bug bootstrap/22330] Building a cross linux->win32 incorrectly sets HAVE_GAS_SHF_MERGE true

------- Additional Comments From ovidr at users dot sourceforge dot net  2005-07-07 21:24 -------
I don't know how to do that with the current configure.

Build != Host 
--build=i686-pc-linux-gnu --host=i686-pc-mingw32 --target=i686-pc-mingw32

>From configure.ac:
# If build != host, and we aren't building gas in-tree, we identify a
# build->target assembler and hope that it will have the same features
# as the host->target assembler we'll be using.

(which is wrong in this case)

And configure.ac is using 'test -x' on environment variables $AS and 
$AS_FOR_TARGET, which always have their paths stripped, so I can't set it 
to "/home/gcc/build/crossgcc/bin/i686-pc-mingw32-as" or "i686-pc-mingw32-as" 
and pass the "test -x" test, even though that is the $AS that will ultimately 
be used to assemble. 

Manually changing the "elif test -x "$AS_FOR_TARGET"; then" line in 
gcc/configure to "-n" makes it use the env variable, and sets 
HAVE_GAS_SHF_MERGE 0, which is what I want, but I doubt this is the right way 
to do it.

Actually it better or there is something wrong as basicially you cannot really mix match the as versions 
of a Candian cross.
