Subject: [PATCH 0/8] configure: Change to -std=gnu11
Date: Fri, 11 Jun 2021 16:33:39 -0700 [thread overview]
Message-ID: <20210611233347.653129-1-richard.henderson@linaro.org> (raw)
Now that we assume gcc 7.5 as a minimum, we have the option
of changing to a newer C standard. The two major ones that
I think apply are _Generic and _Static_assert.
While Paolo created a remarkably functional replacement for _Generic
using builtins, the error messages that you get out of the keyword
are *vastly* more intelligable, and the syntax is easier to read.
While I'd like to prefer _Static_assert over QEMU_BUILD_BUG_ON
going forward, and would like to convert existing uses, that is
a much bigger job. Especially since the test condition is inverted.
In the meantime, can drop the configure detection.
