Mans Rullgard	cf9c227e58	ARM: fix vp8 neon with pic enabled The assembler emits literal pools too far from the load instructions, so we must do it explicitly at a suitable location. Signed-off-by: Mans Rullgard <mans@mansr.com> (cherry picked from commit `8b454c352f`)	14 years ago

Mans Rullgard	451b4b8635	Rearrange MpegEncContext to simplify access from asm This moves the fields needed by asm near the top, before any structs or other members which complicate the offset calculation. Modifying other structs will no longer require updating the offsets, and the asm code is slightly simpler due to the smaller offsets.
