Hi,
After trying qemu master:
commit 474f3938d79ab36b9231c9ad3b5a9314c2aeacde
Merge: 68d7ff0 14f5d87
Author: Peter Maydell <peter.maydell@linaro.org>

I found several regressions compared to qemu-3.1 when running the GCC testsuite.
I'm attaching a tarball containing several GCC tests (binaries), needed shared libs, and a short script to run all the tests.
All tests used to pass w/o error (one of them is verbose), but with a
recent qemu, all of them make qemu crash:
qemu: uncaught target signal 6 (Aborted) - core dumped
This was noticed with GCC master configured with
--target arm-none-linux-gnueabi
--with-mode arm
--with-cpu cortex-a9
and calling qemu with --cpu cortex-a9 (the script uses "any", this makes
no difference).
I have noticed other failures with arm-v8 code, but this is probably the
same root cause. Since it's a bit tedious to manually rebuild & extract
the testcases, I'd prefer to start with this subset, and I can extract
more if needed later.
Thanks

I bisected a chunk of the errors to:
commit c6fb8c0cf704c4a1a48c3e99e995ad4c58150dab (refs/bisect/bad)
Author: Richard Henderson <richard.henderson@linaro.org>
Date: Mon Feb 25 11:42:35 2019 -0800
tcg/i386: Support INDEX_op_extract2_{i32,i64}
Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
Specifically I think when tcg_gen_deposit_i32 handles the if (ofs + len
== 32) case.
