Subject: Re: [PATCH 4/n] modula-2, driver: Handle static-libstd++ for targets without static/dynamic
Date: Fri, 30 Dec 2022 11:00:23 +0000 [thread overview]
Message-ID: <F3A9F9AF-50C4-410E-B21E-AFEAD722B3EF@sandoe.co.uk> (raw)
In-Reply-To: <20221230105821.61331-1-iain@sandoe.co.uk>
Oops pressed ‘send' too soon - this is part of the series for Darwin:
There are several modula-2 issues on Darwin, some blocking bootstrap on
one or more system versions.
This has been tested on powerpc/i688-darwin9 .. x86_64-darwin10,17,21 and
the prototype aarch64-darwin branch on darwin21.
OK for trunk?
thanks
Iain
