Subject: [04/23] Move iterator_range to a new iterator-utils.h file
Date: Fri, 13 Nov 2020 08:13:27 +0000 [thread overview]
Message-ID: <mptzh3l8yjc.fsf@arm.com> (raw)
In-Reply-To: <mpth7ptad81.fsf@arm.com> (Richard Sandiford's message of "Fri, 13 Nov 2020 08:10:54 +0000")
A later patch will add more iterator-related utilities. Rather than
putting them all directly in coretypes.h, it seemed better to add a
new header file, here called "iterator-utils.h". This preliminary
patch moves the existing iterator_range class there too.
I used the same copyright date range as coretypes.h “just to be sure”.
gcc/
* coretypes.h (iterator_range): Move to...
* iterator-utils.h: ...this new file.
