Description Raymond Jennings 2013-06-15 06:16:43 UTC 
Bootstrapping triples compilation time.

Allow it to be disabled, perhaps with a use flag or soemthing.

Upstream suggested --disable-bootstrap in configure, but the ebuild choked.  On further inspection I find that the toolchain eclass is forcing "bootstrap-lean" as a target.

Reproducible: Always
Comment 1 Raymond Jennings 2013-06-15 06:17:55 UTC 
Just of note:  disabling bootstrap is supported by upstream gcc.
Comment 2 Ryan Hill (RETIRED) gentoo-dev 2013-06-15 18:06:59 UTC 
That's why we use GCC_MAKE_TARGET rather than hardcoding it:

GCC_MAKE_TARGET="all" EXTRA_ECONF="--disable-bootstrap" emerge -av gcc
Comment 3 Raymond Jennings 2013-06-15 18:41:33 UTC 
Thanks for documenting this.

    toolchain.eclass: allow forcefully disabling bootstrapping for development

    Users should *absolutely not* do this. It's just useful for quickly
    testing eclass changes.

    The resultant compiler may not be safe to use. Especially so if
    unusual flags and environment is used.
