            Bug ID: 108491
           Summary: cross compiler does not work: cc1: error:
                    ‘-msecure-plt’ not supported by your assembler
           Product: gcc
           Version: 13.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: marxin at gcc dot gnu.org
                CC: segher at gcc dot gnu.org
  Target Milestone: ---
              Host: x86_64-linux-gnu
            Target: powerpc-freebsd13

Building the cross-compiler fails with:

./xgcc -B./ -B/home/marxin/bin/gcc/powerpc-freebsd13/bin/ -isystem
/home/marxin/bin/gcc/powerpc-freebsd13/include -isystem

 -xc -nostdinc /dev/null -S -o /dev/null
-fself-test=/home/marxin/Programming/gcc2/gcc/testsuite/selftests
cc1: error: ‘-msecure-plt’ not supported by your assembler
make: *** [/home/marxin/Programming/gcc2/gcc/c/Make-lang.in:128: s-selftest-c]
Error 1
make: *** Waiting for unfinished jobs....

Shouldn't we add detection for an assembler, if it's supported or not?

--- Comment #1 from Segher Boessenkool <segher at gcc dot gnu.org> ---
This error is from sysv4.h SUBTARGET_OVERRIDE_OPTIONS.  -msecure-plt is
unconditionally required.

It looks like an oversight that it is not required in the assembler you
used (which is that?)

how did you configure?  does the build pick up the host tools?

Did you compile binutils first?
Are you doing a combined build?

checking for as... no
checking for powerpc-freebsd13-as... no

So the answer to my question of did you compile binutils first is no and you
are not doing a combined build either:
checking where to find the target as... pre-installed

So this is not a bug that needs to be fixed really.

--- Comment #7 from Segher Boessenkool <segher at gcc dot gnu.org> ---
It is not a bug even.

However, our documentation could be clearer that you need a working assembler
and linker etc., and the hint that putting binutils in the same prefix (before
doing GCC) makes everything automatically work could be helpful?

Isn't this what --with-gnu-as --with-gnu-ld options are for?
