Subject: Re: [Patch, Fortran] PR 85599: warn about short-circuiting of logical expressions for non-pure functions
Date: Wed, 18 Jul 2018 18:43:00 -0000 [thread overview]
Message-ID: <CAKwh3qj2zdFD1KFeekP=u+Nu7oeZ9OiZ5wPVSP=7u9CCEAB0Yw@mail.gmail.com> (raw)
In-Reply-To: <CAKwh3qjik5=t5OBf_Wmf-b=DrdcxuhL4O5EXY8aEM1Zw+G7eug@mail.gmail.com>
I have now finally committed this as r262860. Thanks everyone for
helping to bring this to a constructive end (and especially to Thomas
for the useful input and for putting up with me).
Cheers,
Janus
PS: The next step here would be to tackle PR57160 and avoid the
short-circuiting with -O0 (I might actually look into that soon). Once
that is done we could even talk about further optimizations (as
previously suggested by Thomas), provided they are only done with
-O... flags and warned about with appropriate -W... flags.
