Hi everyone,

We've been stuck on EAPI=4 with toolchain.eclass for a while.  This is
causing problems with subslotting libraries like mpfr, mpc, gmp and isl
that gcc depend on (see bug #642316).  I went through and made the
changes necessary to get the eclass up to EAPI=5 and compile tested
across the board (ie all dependent ebuilds) for amd64.  Everything looks
good, so please review and I'll commit if we're okay.

Subject: [PATCH 1/2] toolchain.eclass: update to EAPI=5 standards

This eclass is inherited by ebuilds in sys-devel/{gcc,kgcc64,gcc-apple},
each which make use of different IUSE flags.   This causes problems with
`use X` construcitons when X is not in the IUSE flags.  At EAPI=4 this
simply emitted a warning, while at EAPI=5 this is an error.  We update
the eclass to make use of use_if_iuse and similar constructions where
necessary to bring the eclass into compliance with EAPI=5.

Does this work? The "use" function supports negation (undocumented, but
it's in the PMS), but I don't think use_if_iuse does.

Okay I'll read the code and test.  You're right that I just assumed it
worked liked "use" wrt negation so the semantics need to be checked.

Thanks for looking this over carefully.

It looks like it would not work as expected because eutils.eclass has

in_iuse() {
    debug-print-function ${FUNCNAME} "${@}"
    [[ ${#} -eq 1 ]] || die "Invalid args to ${FUNCNAME}()"

    local flag=${1}
    local liuse=( ${IUSE} )

    has "${flag}" "${liuse[@]#[+-]}"
}

use_if_iuse() {
    in_iuse $1 || return 1
    use $1
}

So $1 in use_if_iuse binds to "!nopie" and then in in_iuse again to
"!nopie" which then messes up the has line, looking for a flag named
"!nopie" in IUSE which will always be true.

I'll change that line to

use_if_iuse nopie || return 0

Grepping the tree, I see only instances of

if ! use_if_iuse X ...

which is good.

-	confgcc+=( $(use_enable altivec) )
+	in_iuse altivec && confgcc+=( $(use_enable altivec) )

^ Just as an example, such a construct may change the "default setting" when 
no altivec useflag exists...

Imagine that upstream enables altivec by default (?). In earlier eapis, 
use_enable with a non-existing useflag returned --disable-altivec (?). Now, 
without the useflag, no setting is passed to configure, and it's enabled.

So, while this all works in principle, it may need careful per-flag review.

Okay so I tested and found that there is no change in the default
settings due to the above construct (and there are a few).  The way I
did it was I built >=gcc-4.9.4 with and without the toolchain.eclass
patch and compared the config.log's (there's about 33 per version of
gcc).  There were no substantial differences.  If there would have been
a change in the default behavior, then lines like following would have
shown a difference.


  $ /var/tmp/portage/sys-devel/gcc-7.2.0/work/gcc-7.2.0/configure

I didn't test earlier gcc versions because they're masked.  I tested
only on amd64 but I think that's oaky.  The only flag my tests don't
cover is the altivec flag (which is for ppc/ppc64), but it defaults off
on all gcc versions.

I think this puts your concern to rest.
