avcodec/arm/sbcenc: avoid callee preserved vfp registers When compiling FFmpeg with GCC-9, some very random segfaults were observed in code which had previously called down into the SBC encoder NEON assembly routines. This was caused by these functions clobbering some of the vfp callee saved registers (d8 - d15 aka q4 - q7). GCC was using these registers to save local variables, but after these functions returned, they would contain garbage. Fix by reallocating the registers in the two affected functions in the following way: ff_sbc_analyze_4_neon: q2-q5 => q8-q11, then q1-q4 => q8-q11 ff_sbc_analyze_8_neon: q2-q9 => q8-q15 The reason for using these replacements is to keep closely related sets of registers consecutively numbered which hopefully makes the code more easy to follow. Since this commit only reallocates registers, it should have no performance impact. Signed-off-by: James Cowgill <firstname.lastname@example.org>
