This patch obviously depends on Andrew's; he wrote in the previous email
of this thread regarding his patch:
Andrew Stubbs wrote:
This is enough to get gfx1100 working for most purposes, on top of the
patch that Tobias committed a week or so ago; there are still some test
failures to investigate, and probably some tuning to do.
It might also get gfx1030 working too. @Richi, could you test it,
please?
I can't test the other multilibs right now. @PA, can you test it please?
I can self-approve the patch, but I'll hold off the commit until the
test results come back.
Okay to enable gfx1100 multilib building and to document gfx1100 in the
manual?
(I mean, obviously, only after Andrew committed his patch. For gfx1030,
we might eventually also enable gfx1030 multilib support; if Richard
confirms that collaterally fixes gfx1030, we probably should - and
depending on the number/kinds of testsuite, we could then document it
or not, I guess.)

amdgcn: config.gcc - enable gfx1100 multilib; add gfx1100 to docs
gcc/ChangeLog:
* config.gcc (amdgcn-*-*): Add gfx1100 to TM_MULTILIB_CONFIG.
* doc/install.texi (Configuration amdgcn-*-*): Mention gfx1100.
* doc/invoke.texi (AMD GCN Options): Add gfx1100 to -march/-mtune.
libgomp/ChangeLog:
* testsuite/libgomp.c/declare-variant-4.h: Add variant functions
for gfx1030 and gfx1100.
* testsuite/libgomp.c/declare-variant-4-gfx1100.c: New test.
