From f1d5183124d3e18d410ded61e45adb9a23b23c83 Mon Sep 17 00:00:00 2001 From: Mike Karels Date: Tue, 25 Jul 2023 18:58:51 -0500 Subject: [PATCH] arm64 lib32: change clang to allow -m32 on arm64 The FreeBSD driver support for clang tested explicitly for 32-bit Intel, MIPS, or PowerPC targets where /usr/lib32/libcrt1.o was present to decide whether -m32 should use /usr/lib32. At jrtc27's suggestion, simply test for a 32-bit platform rather than adding arm to the list. Upstreamed as https://github.com/llvm/llvm-project/commit/3450272fc281979388bb845a9fffb59b42cc2e7e Bump the freebsd version to force a bootstrap build. This is one step in adding support for -m32 on arm64.
