Not sure if this is fixable outside of using --no-integrated-as without reworking the asm.
Created attachment 151625 [details] disable clang integrated assembler clang integrated assembler does not support GNU AS assembler directives, libav authors suggest to use gas-preprocessor to feed clang (cf https://patches.libav.org/patch/50894/) I think the easiest solution is to disable clang integrated assembler (cf attached patch)
I will commit this if there's no objections. Fixes build on head for ARMv6
A commit references this bug: Author: sbruno Date: Fri Jan 16 22:34:23 UTC 2015 New revision: 377204 URL: https://svnweb.freebsd.org/changeset/ports/377204 Log: These ports utilize GAS assembly and probably won't ever change. For the ARM case, do not use -integrated-as.
