Description Iain Sandoe 2019-06-01 23:30:51 UTC
This is a place to gather the (several) contributing factors to the apparent regression in handling Darwin / MacOS X objective c headers.
Comment 1 Iain Sandoe 2019-06-01 23:40:20 UTC
The short list of major factors:

1.  (78352) GCC lacks support for the Apple "blocks" extension to the C family of languages.

 - block syntax appears without guards in many places in modern Darwin system headers.

2. (90707) - GNU Objective C (C++) does not support nullability syntax.

 - nullability introduces new keywords for objective c and, unlike the equivalent markup in C/C++, these cannot be worked around with preprocessor hacks,

3. (90708) - GNU Objective C (C++) does not support lightweight generics.

 - likewise this is an invasive syntax change that can't be worked around.

4. instancetype keyword (partially implemented, at least we can consume the syntax).

-----

However, taking these points aside - for the APIs currently implemented by GNNU objective c - we should seek a mechanism to monitor for regressions.

[objective-c/c++, testsuite, 1/3] Workaround for PR90709.

Since we cannot parse the current NeXT headers, because of PR90709 and its
dependents, we have a large amount of testsuite noise for Darwin platforms.
In order to restore the usefulness of the testsuite, we are going add headers
without the modern syntax elements that trigger the bug, and use these for
test runs on newer Darwin.

The headers are imported from GNUStep, with some local modifications to make
sure that __BLOCKS__ is honoured as a gate for Apple-style blocks closures.

CF-CFString.h, F-NS*.h are proxy headers that use the installed CoreFoundation
or Foundation headers on systems <= Darwin12 and the GNUStep headers for newer.

[objective-c/c++, testsuite] Workaround for PR90709.

Since we cannot parse the current NeXT headers, because of PR90709 and its
dependents, we have a large amount of testsuite noise for Darwin platforms.
In order to restore the usefulness of the testsuite, we are going add headers
without the modern syntax elements that trigger the bug, and use these for
test runs on newer Darwin.

The headers are imported from GNUStep, with some local modifications to make
sure that __BLOCKS__ is honoured as a gate for Apple-style blocks closures.

CF-CFString.h, F-NS*.h are proxy headers that use the installed CoreFoundation
or Foundation headers on systems <= Darwin12 and the GNUStep headers for newer.

Use the CF-CFString.h, F-NS*.h proxy headers where needed in the objective-c
testsuite. Make minor adjustments to tests as required, providing that those
do not alter the test intent.

CF-CFString.h, F-NS*.h are proxy headers that use the installed CoreFoundation
or Foundation headers on systems <= Darwin12 and the GNUStep headers for newer.

Use the CF-CFString.h, F-NS*.h proxy headers where needed in the objective-c
testsuite. Make minor adjustments to tests as required, providing that those
do not alter the test intent.

Comment 10 Eric Gallager 2020-10-23 04:21:13 UTC
I just ran into this trying to compile my fork of emacs on Catalina; from looking at config.log (5.3MB!) it looks like the lack of support for "nullable" (bug 90707) is the biggest missing feature
