Bug ID: 94998
Summary: GCC 10 won't configure for host=x86, build!=host,
linker=bfd due to CET
Product: gcc
Version: 10.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: bootstrap
Assignee: unassigned at gcc dot gnu.org
Reporter: harald at gigawatt dot nl
Target Milestone: ---
Configuring libiberty fails when gcc is configured as
../gcc-10.1.0/configure --build=x86_64-forcecross-linux-gnu
--host=x86_64-pc-linux-gnu --enable-languages=c,c++ CC='gcc-10.1.0
-fuse-ld=bfd' CXX='g++-10.1.0 -fuse-ld=bfd'
(This is a shorter simplified configure line to make it easier to reproduce the
problem, not the one I was originally using. Please ignore the fact that it's
weird to trick the configure script into thinking it's cross-compiling when
it's not.)
It fails like so:
[...]
checking for CET support... configure: error: in
`/h/gcc-10.1.0-build/libiberty':
configure: error: cannot run test program while cross compiling
See `config.log' for more details
make[1]: *** [Makefile:7986: configure-libiberty] Error 1
make[1]: Leaving directory '/h/gcc-10.1.0-build'
make: *** [Makefile:955: all] Error 2
It works with gold because the linker options '-Wl,-z,ibt,-z,shstk' are not
accepted by gold (at least in binutils 2.34), so it never gets to the point
where it tries to run the test program.

(The bootstrap component is probably wrong if this only shows up in cross
compilations.)
