Bug 686512 – sys-devel/gcc compiled with debug info, not stripped

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Hans F. Nordhaug 2019-05-21 21:08:33 UTC]

(I have an up-to-date Gentoo installation.)

I first discovered that my newly installed GCC 8.3.0 was huge. My initial thought was that this is related to changes between GCC 7.3.0 and 8.3.0. However, recompiling GCC 7.3.0 made that package huge too. The reason turned out to be that the files included debug_info and were unstripped. I haven't changed USE flags since the original installation so I don't understand, and I don't see any related changes to the toolchain eclasses.

What is going on?

It's an effect of https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=97f0db2416f531bcfbc20c64d64bde384c1aab23.

We'll fix it when toolchain.eclass gets EAPI=7 support and ability to call dostrip to selectively disabling stripping.

    toolchain.eclass: enable selective stipping for EAPI=7
    
    Before the change we stripped no binaries or object files
    for gcc on any EAPI.
    
    After the change we strip all native binaries, libraries
    and object files (only on EAPI=7).
    
    Non-native binaries (cross-compiler case) is skipped by
    means of 'dostrip -x'.

EAPI=7 gcc ebuilds should do nicer stripping now. But there are none in the ::gentoo tree yet :)
