From c994a3ec7ecc8bd2a837b2061e8a76eb8efc082b Mon Sep 17 00:00:00 2001 From: Nick Desaulniers Date: Mon, 28 Jun 2021 14:50:26 -0700 Subject: [PATCH] MIPS: set mips32r5 for virt extensions Clang's integrated assembler only accepts these instructions when the cpu is set to mips32r5. With this change, we can assemble malta_defconfig with Clang via `make LLVM_IAS=1`.
