Bug ID: 65881
Summary: no documentation of __uint128_t
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: shawn at churchofgit dot com
gcc on x86_64 recognizes __uint128_t, but this is not documented along with
__int128, also there is no warning when a target does not support __uint128_t,
like there is with __int128:
triangle64.c:32:1: error: ‘__int128’ is not supported for this target
A unsigned 128-bit type is needed because it has defined integer overflow.
