Bug ID: 44939
Summary: Support -std=c++20/gnu++20
Product: clang
Version: trunk
Hardware: PC
OS: All
Status: NEW
Severity: enhancement
Priority: P
Component: C++2a
Assignee: unassignedclangb...@nondot.org
Reporter: romain.geiss...@amadeus.com

Hi,
C++20 was marked as (technically) done at the Prague meeting last week, so now
there is no need to call this standard C++2a, it is officially C++20. Thus
clang should accept -std=c++20/gnu++20 which doesn't seem to be the case with
the current trunk (at least on Compiler Explorer). gcc has added this very
recently with this commit:
https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=fb26050409473f5be54465beca114b7e48de43aa
I also think this is a possible candidate for a backport into the soon to be
released Clang 10.
Cheers,
Romain
