Bug ID: 102989
Summary: Add Clang's _ExtInt(N)
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: colomar.6.4.3 at gmail dot com
Target Milestone: ---
I'd like to see Clang's _ExtInt(N) arbitrary-precision fixed-width integers
(https://clang.llvm.org/docs/LanguageExtensions.html#extended-integer-types) in
GCC.
I have in mind at least a scenario where they would help:
- Bignum
They are much simpler than using GMP. I have a project of mine where I ended
up doing my own type made of an array: 'typedef uint64_t uint512_a[8];'.
Having the ability to handle 'typedef unsigned _ExtInt(512) uint512;' as easily
as __int128 is great.
