Subject: [PATCH 0/2] Optimize is_bounded_array trait performance
Date: Mon, 11 Sep 2023 19:38:37 -0700 [thread overview]
Message-ID: <20230912024920.55120-1-kmatsui@gcc.gnu.org> (raw)
This patch series optimizes is_bounded_array trait
performance. The first patch implements __is_bounded_array
built-in trait. The second patch optimizes is_bounded_array
trait performance by using __is_bounded_array built-in trait
if available.
The performance improvement is shown in the following benchmark:
