Subject: [glibc] Declare wcstofN, wcstofNx for C2x
Date: Tue, 14 Mar 2023 18:11:51 +0000 (GMT) [thread overview]
Message-ID: <20230314181151.A607F3858D33@sourceware.org> (raw)
https://sourceware.org/git/gitweb.cgi?p=glibc.git;h=9e2ff880f3cbc0b4ec8505ad2ce4a1c92d7f6d56
commit 9e2ff880f3cbc0b4ec8505ad2ce4a1c92d7f6d56
Author: Joseph Myers <joseph@codesourcery.com>
Date: Tue Mar 14 18:11:27 2023 +0000
Declare wcstofN, wcstofNx for C2x
WG14 accepted the changes in N3105 to define wcstofN and wcstofNx
functions for C2x. Thus enable those for C2x (given also __GLIBC_USE
(IEC_60559_TYPES_EXT) and support for the relevant _FloatN / _FloatNx
type) rather than only for __USE_GNU.
Tested for x86_64.
