[Qemu-devel] [PATCH 000/126] Rewrite s390x translator

[Richard Henderson]

As promised the other week.  I've cleaned up the patch set and
re-based it on Blueswirl's areg0 patch set.  For reference, the
entire patch set is available at

  git://repo.or.cz/qemu/rth.git rth/s390-reorg-3

Testing has mostly been on the gcc testsuite, where the execute
test failures are reduced to

FAIL: gcc.dg/attr-ifunc-1.c execution test
FAIL: gcc.dg/attr-ifunc-3.c execution test
FAIL: gcc.dg/attr-ifunc-4.c execution test
FAIL: gcc.dg/attr-ifunc-5.c execution test
FAIL: gcc.dg/cdce1.c execution test
FAIL: gcc.dg/cleanup-11.c execution test
FAIL: gcc.dg/cleanup-9.c execution test
FAIL: gcc.dg/torture/pr41094.c  -O0  execution test
FAIL: gcc.dg/torture/tls/tls-test.c * execution test

I'll probably start trying out the glibc testsuite next, as
that's quite likely to flush out remaining problems with the
fp support (both cdce1 and pr41094 are both failures in pow).

I've also done some testing with -march={z10,z196}, but I
don't have those results handy atm.
