Finally I found an ARM machine and was able to build ARM32 gcc on it, and
reproduced the failures. The Go programs aborted, in parse_lsda_header,
called from probestackmaps in the runtime startup. It seems that
_Unwind_GetLanguageSpecificData doesn't return a valid LSDA when called
from a callback
Cherry, see
https://gcc.gnu.org/ml/gcc-testresults/2018-12/msg02241.html
https://gcc.gnu.org/ml/gcc-testresults/2018-12/msg02240.html
still shows ~180 test failures on ARM32. Sorry, no access to an ARM32 box until
next year.

Thank you, Matthias!
>From the log, essentially all the tests aborted. The only place the new
code can cause abort on all programs that I can think of is in the runtime
startup code, probestackmaps, which calls value_size, which aborts due to
an unhandled case. I haven't been able to try out on

Sorry about the breakage. Thanks for the patch.

This libgo patch by Cherry Zhang adds support for precise stack
scanning to the Go runtime. This uses per-function stack maps stored
in the exception tables in the language-specific data area. The
compiler needs to generate these stack maps; currently this is only
done by a version of LLVM, not
