From 2105a97d4afa5022375c9b366138049da5b0a6a2 Mon Sep 17 00:00:00 2001 From: "A. Wilcox" Date: Wed, 10 Jul 2024 08:27:43 -0500 Subject: user/llvm14: Fix GCC 13-adjacent bugs Backport the GCC miscompile workaround from LLVM 18. Use the old x87 excess precision behaviour to fix most of the tests. Still no idea why 32-bit Intel wants new shiny colours for the graph.
