Hi.
The patch is about simplification and usage of enum types. ENDP integer
does not make much sense in this usage.
Patch can bootstrap on x86_64-linux-gnu and survives regression tests.

This is one more enhancement of JSON intermediate format export. Apart from
that, I also improved documentation of the format and gcov-dump output.
Patch survives gcov.exp regression tests. I'm going to install the patch

Hi!
These are the only remaining cases of gcc-internal-format diagnostics using
HOST_WIDE_INT_PRINT*. That is wrong because the string depends on the exact
host, and xgettext doesn't handle it anyway, so in gcc.pot the messages are

Hi,
This patch moves the one -fsantize=undefined test to a new ubsan test
directory, guarded by check_effective_target_fsanitize_undefined.
Another recent change to gdc_include_flags left one variable unused,
also noticed that flags was never explicitly returned. Both have been
fixed up.
