Created attachment 314861 [details] remove forcing of armv7 arch on all arm targets from configure.in After this patch compile goes through, even all but one js-api test passes (testConservativeGC crashes)
provide the full build.log
Created attachment 314901 [details] build.log
Created attachment 314903 [details] emerge --info
get me a backtrace, the slight difference between the two should not be causing a build failure, they are not seeing a failure on any other distro.
Created attachment 328004 [details, diff] backport of ARM portion of configure.in from 1.8.7 The first patch doesn't work -- it causes failures on armv7's. I have backported the ARM configure stuff from spidermonkey-1.8.7 to spidermonkey-1.8.5 with this patch; after some testing which steev has promised to do for me I will commit it to the tree.
Right, so that didn't work either, but I distilled all of the configure stuff down to the bare necessities -- all that is needed for ARM by any of the JS code, is whether or not THUMB2 support exists. I scraped a bit of code from WINE that works successfully for this and replaced all of the existing ARM-related overrides with that. steev was nice enough to test for me on three or four different ARMs, all succeeded.
