Hi

On Thu, Oct 7, 2021 at 5:28 PM Paol= o Bonzini <pbonzini@redhat.com> wrote:
Rig= ht now meson_options.txt lists about 90 options.=C2=A0 Each option
needs code in configure to parse it and pass the option down to Meson as a -D command-line argument; in addition the default must be duplicated
between configure and meson_options.txt.=C2=A0 This series tries to remove<= br> the code duplication by generating the case statement for those --enable and --disable options, as well as the corresponding help text.

About 80% of the options can be handled completely by the new mechanism. Eight meson options are not of the --enable/--disable kind.=C2=A0 Six more = need
to be parsed in configure for various reasons documented in the patch,
but they still have their help automatically generated.

The advantages are:

- less code in configure

- parsing and help is more consistent (for example --enable-blobs was
=C2=A0 not supported)

- options are described entirely in one place, meson_options.txt.
=C2=A0 This make it more attractive to use Meson options instead of
=C2=A0 hand-crafted configure options and config-host.mak

A few options change name: --enable-tcmalloc and --enable-jemalloc
become --enable-malloc=3D{tcmalloc,jemalloc}; --disable-blobs becomes
--disable-install-blobs; --enable-trace-backend becomes
--enable-trace-backends.
