[PATCH v3 4/4] bpf: add tests for ints larger than 128 bits
From: Sean Young
Date: Tue Jan 05 2021 - 09:46:38 EST
clang supports arbitrary length ints using the _ExtInt extension. This
can be useful to hold very large values, e.g. 256 bit or 512 bit types.
Larger types (e.g. 1024 bits) are possible but I am unaware of a use
case for these.
This requires the _ExtInt extension enabled in clang, which is under
review.
