When compiling for THUMB-2, the conditional branch to PLT results in a R_ARM_THM_JUMP19 relocation. Some linkers don't support this relocation in THUMB-2 (ld.gold), while others can end up truncating the relocation to fit (ld.bfd).
Adding an "it eq" before the branch converts it into an unconditional branch, which uses R_ARM_THM_JUMP24 relocation that has a range of 16MB. See https://github.com/android-ndk/ndk/issues/337 for background. The current workaround is to disable neon during gstreamer build, which is not optimal and can be reverted after this patch: https://github.com/freedesktop/gstreamer-cerbero/commit/41556c415739fbc3a72c7eaee7e70a565b719b2f --- libswresample/arm/audio_convert_neon.S | 1 + 1 file changed, 1 insertion(+) diff --git libswresample/arm/audio_convert_neon.S libswresample/arm/audio_convert_neon.S index 1f88316ddec838dfe791b08cbe72533207994741..bc933fb4bd00071702f553cc0f3e74797c33ab12 100644 --- libswresample/arm/audio_convert_neon.S +++ libswresample/arm/audio_convert_neon.S @@ -134,6 +134,7 @@ function swri_oldapi_conv_fltp_to_s16_nch_neon, export=1 itt lt ldrlt r1, [r1] blt X(swri_oldapi_conv_flt_to_s16_neon) + it eq beq X(swri_oldapi_conv_fltp_to_s16_2ch_neon) push {r4-r8, lr} -- 2.13.5 _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
