This creates proper position independent code when accessing data symbols if CONFIG_PIC is set. References to external symbols should now use the movrelx macro. Some additional code changes are required since this macro may need a register to hold the GOT pointer. Signed-off-by: Mans Rullgard <mans@mansr.com>

AS libavcodec/arm/ac3dsp_armv6.o ffmpeg-src/libavcodec/arm/ac3dsp_armv6.S: Assembler messages: ffmpeg-src/libavcodec/arm/ac3dsp_armv6.S:40: Error: selected processor does not support `movw r8,#0x1fe0' make[1]: *** [libavcodec/arm/ac3dsp_armv6.o] Error 1 MOVW is ARMv7 way to load constant: * movw, or move wide, will move a 16-bit constant into a register, implicitly zeroing the top 16 bits of the target register. * movt, or move top, will move a 16-bit constant into the top half of a given register without altering the bottom 16 bits To load 32 bit constant, movw lower16; movt upper16; is better than ldr if available, because: While this approach takes two instructions, it does not require any extra space to store the constant so both the movw/movt method and the ldr method will end up using the same amount of memory. Memory bandwidth is precious in and the movw/movt approach avoids an extra read on the data side, not to mention the read could have missed the cache. But here it is armv6 optimization, so that we have to use ldr. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
