From: Mark Rousskov Date: Sun, 31 Jul 2022 21:45:15 +0000 (-0400) Subject: Enable downloading prebuilt LLVM in test builders X-Git-Url: https://git.lizzy.rs/?a=commitdiff_plain;h=6c7f30114515111c53224e2de1434a324f73c0e8;p=rust.git Enable downloading prebuilt LLVM in test builders See comment added for details on the test builder restriction. This is primarily intended for macOS CI, but is likely to be a slight win on other builders too. --- diff --git a/.github/workflows/ci.yml b/.github/workflows/ci.yml index 7eb41fec36a..11b115cb2ff
