Still worried this might not be complete. It's basically fixing the fallout from Khem's patches to remove -march options from the CPU specific ARM machine includes, right? If so then any ARM machine with CPU specific tuning (other than cortex) is still going to be affected. What's the reason for parsing TUNE_FEATURES to detect the ARM architecture level? Couldn't GOARM be set correctly just by using of the _armv5, _armv6, _armv7a and _armv7ve over-rides? https://github.com/golang/go/wiki/GoArm > meta/classes/goarch.bbclass | 4 ++++ > 1 file changed, 4 insertions(+) > > diff --git a/meta/classes/goarch.bbclass b/meta/classes/goarch.bbclass > index 39fea5e..84977a5 100644 > --- a/meta/classes/goarch.bbclass > +++ b/meta/classes/goarch.bbclass > @@ -74,6 +74,10 @@ def go_map_arch(a, d): > def go_map_arm(a, f, d): > import re > if re.match('arm.*', a): > + for el in f.split(): > + m = re.match("cortex[arm](\d.*)", el) > + if m and int(m.group(1)) < 32: > + return '7' > if 'armv7' in f: > return '7' > elif 'armv6' in f: > -- > 2.7.4 > > -- > _______________________________________________ > Openembedded-core mailing list > Openembedded-core@lists.openembedded.org > http://lists.openembedded.org/mailman/listinfo/openembedded-core -- _______________________________________________ Openembedded-core mailing list Openembedded-core@lists.openembedded.org http://lists.openembedded.org/mailman/listinfo/openembedded-core
