Subject: [PATCH] rust-llvm: Compile llvm to use dynamic libraries
Date: Mon, 31 Mar 2025 14:30:44 +0100	[thread overview]
Message-ID: <20250331133044.1944108-1-richard.purdie@linuxfoundation.org> (raw)

Our main llvm recipe uses dynamic linking already but rust-llvm does not.
Enabling this significanly reduces the size of llvm-rust to about a third
of what it was, which is a bettter configuration for us leading to smaller
TMPDIR and sstate objects.
