The global symbols must be marked with the proper type annotations in order for the relocations to be correct. ld.lld: error: external/libxaac/decoder/armv7/ixheaacd_qmf_dec_armv7.c:353:(.text.ixheaacd_esbr_cos_sin_mod+0x3A0): branch and link relocation: R_ARM_THM_CALL to non STT_FUNC symbol: ixheaacd_esbr_cos_sin_mod_loop2 interworking not performed; consider using directive '.type ixheaacd_esbr_cos_sin_mod_loop2, %function' to give symbol type STT_FUNC if interworking between ARM and Thumb is required Bug: 155835175 Test: mm for ARM based build Change-Id: I063cd9716402aaaebbd4273776eadb70314bf5f9
