Still have issues with the non-installed testing.
( mkdir objmic && cd objmic && ../configure

All 3 succeeded for me.
Now, in objhost make check-target-libgomp doesn't really work, in objhost2
it does.
E.g. trying to link target-1.exe, I get:
lto-wrapper: fatal error: Problem with building target image for
x86_64-intelmicemul-linux-gnu.
compilation terminated.
/usr/bin/ld: lto-wrapper failed
collect2: error: ld returned 1 exit status
If I add
-B /usr/src/gcc-git/objinst/usr/local/lib/gcc/x86_64-pc-linux-gnu/5.0.0/ \
-B /usr/src/gcc-git/objinst/usr/local/libexec/gcc/x86_64-pc-linux-gnu/5.0.0/
to the command line so it at least finds mkoffload, it then can't find for
some reason the offload compiler:
(null): fatal error: offload compiler
x86_64-pc-linux-gnu-accel-x86_64-intelmicemul-linux-gnu-gcc not found.
compilation terminated.
lto-wrapper: fatal error:
/usr/src/gcc-git/objinst/usr/local/libexec/gcc/x86_64-pc-linux-gnu/5.0.0//accel/x86_64-intelmicemul-linux-gnu/mkoffload
returned 1 exit status
compilation terminated.
/usr/bin/ld: lto-wrapper failed
collect2: error: ld returned 1 exit status
So, what exactly should be added (by libgomp.exp) so that the testing succeeds
in
the case of non-installed offload and non-installed host compilers?
