Hi,
Since we have the predicate, this patch converts one more check for
essentially the same thing into its use.
It has passed a bootstrap and testsuite on x86_64. I believe it is
obvious enough that I can commit it myself and so will do so later
today.
Thanks,
Martin

testcases in the PR need surprisingly more
effort but the simple one can be fixed now easily by this patch and I'll
work on the others incrementally.
Bootstrapped and currently undergoing testsuite run on x86_64-linux. OK

Hi,
This patch documents the analyzer parameters introduced in
r14-2029-g0e466e978c7286 also in gcc/doc/invoke.texi.
Committed as obvious after testing with make pdf and make info and
eyeballing the result.
Thanks,
Martin

Bootstrapped and tested on x86_64-linux, LTO bootstrap is still
