investigating.

Android such as --keep-unique

2018-05-11 Thread Richard Henderson
[VIRT-243 # ARMv8.1-Atomic instructions ]

v3 posted and merged.

[Upstream]

(Upgraded my laptop to Fedora 28, which lead to...)
Posted a patch for gcc 8 Werrors.
Posted patches for clang 6 Werrors.

Sent pull for Emilio's TranslateOps patches.
Sent pull for my openrisc decodetree patches.
Sent pull for tcg-next.
Reviewed microblaze patches.
Posted two rounds of softfloat snan patches.
Posted two rounds of fp16 patches.

[VIRT-198 # QEMU: SVE Emulation Support ]

Most of this week's work was on indirectly related patch sets.  In particular,
fp16 and atomics.  The last round of check-gcc testing had

FAIL: gcc.dg/vect/slp-multitypes-2.c execution test
FAIL: gcc.target/aarch64/advsimd-intrinsics/vldX.c   -O0  execution test
FAIL: gcc.target/aarch64/advsimd-intrinsics/vqtbX.c   -O0  execution test

as the only remaining (relevant) failures.  I believe that the latter two are
generic tcg failures that are cured by this week's tcg-next pull, but have not
yet re-based everything to be sure.
