* avcodec/dirac_arith: Fix build with PIC and stack-check optionsAnthoine Bourgeois2014-04-091-1/+2
| | | | | | | | | | | Fixes Ticket3540 The function dirac_get_arith_bit in libavcodec/dirac_arith.h can't be built with PIC and check-stack because the asm code needs 6 registers and PIC and check-stack options take 1 each and x86 is quite limited in this area.
