Makefile.kcov: apply needed compiler option unconditionally in CFLAGS_KCOV (2025-05-21 16:08:42 +0200)
----------------------------------------------------------------
require gcc-8 and binutils-2.30
x86 already uses gcc-8 as the minimum version, this changes all other
architectures to the same version. gcc-8 is used is Debian 10 and Red
Hat Enterprise Linux 8, both of which are still supported, and binutils
2.30 is the oldest corresponding version on those. Ubuntu Pro 18.04 and
SUSE Linux Enterprise Server 15 both use gcc-7 as the system compiler
but additionally include toolchains that remain supported.
With the new minimum toolchain versions, a number of workarounds for older
versions can be dropped, in particular on x86_64 and arm64. Importantly,
the updated compiler version allows removing two of the five remaining
gcc plugins, as support for sancov and structeak features is already
included in modern compiler versions.
I tried collecting the known changes that are possible based on the
new toolchain version, but expect that more cleanups will be possible.
Since this touches multiple architectures, I merged the patches through
the asm-generic tree.
