Description Mark Millard 2015-12-20 09:05:56 UTC
Created attachment 164411 [details]
svnlite diff output for sys/boot/. . .

[Note: I do not have a context for checking universal builds but the changes below are all in MACHINE_ARCH sections limited to powerpc64.]

Based on errors I got trying to use devel/powerpc64-gcc for buidlworld activity I suggest the following patches to the LDFLAGS handling in sys/boot/ofw/Makfile.inc , sys/boot/powerpc/Makefile , and sys/boot/uboot/Makefile.inc for powerpc64 use:
(Also as an attachment that should preserve tabs and such.)

Comment 1 Mark Millard 2016-07-11 21:19:12 UTC
As of 11.0-BETA1 (-r302457) these changes are still needed to allow building a libc++ based powerpc64 environment via devel/powerpc64-gcc (and so devel/powerpc64-xtoolchain-gcc).

Being that powerpc64 is tier 2 and devel/powerpc64-gcc is involved in what this helps: I'm not so sure that 11.0-RELEASE would pick these up but may be 11.1-RELEASE would (and 12-CURRENT before that).
Comment 2 Mark Millard 2017-01-10 10:30:37 UTC
Looks like I misclassified this as misc instead of
kernel back on 2015-Dec-20. So set it to kernel now.
