From 75c53905f8738fecf691a78de401250e298900f9 Mon Sep 17 00:00:00 2001 From: Conor Dooley Date: Sun, 8 Jan 2023 16:33:56 +0000 Subject: RISC-V: remove toolchain version checks for Zicbom Commit b8c86872d1dc ("riscv: fix detection of toolchain Zicbom support") fixed building on systems where Zicbom was supported by the compiler/assembler but not by the linker in an easily backportable manner. Now that the we have insn-defs for the 3 instructions, toolchain support is no longer required for Zicbom. Stop emitting "_zicbom" in -march when Zicbom is enabled & drop the version checks entirely.
