#67890: blink @1.0.0: error: address argument to atomic operation must be a pointer
to non-const _Atomic type
------------------------+-------------------------

Type: defect | Status: assigned
Priority: Normal | Milestone:
Component: ports | Version: 2.8.1
Keywords: highsierra | Port: blink
------------------------+-------------------------
On High Sierra and earlier (actually `{clang >= 700 < 1001}` as far as I
know):
https://build.macports.org/builders/ports-10.13_x86_64-builder/builds/200034/steps
/install-port/logs/stdio
{{{
./blink/jit.h:270:10: error: address argument to atomic operation must be
a pointer to non-const _Atomic type ('const _Atomic(bool) *' invalid)
return atomic_load_explicit(&jit->disabled, memory_order_acquire);
^ ~~~~~~~~~~~~~~
}}}
See https://github.com/php/php-src/issues/8881 for some background. It
seems that there was a mistake in the original version of the C11 standard
(something that should have been `const` was defined to be non-`const`),
which clang obeyed, and which was changed in later versions of the
standard; this code appears to be written to the revised C11 standard.
To address that PHP issue, the `const`-ness is casted away like this:
browser:macports-ports/lang/php/files/patch-php82-atomic.diff
A similar patch could be written for blink.
