r1206 | funman | 2012-07-18 11:14:09 +0200 (Wed, 18 Jul 2012) | 15 lines Changed paths: M /trunk/libmpeg2/motion_comp_arm_s.S Functions MC_put_o_16_arm, MC_put_o_8_arm, MC_put_x_16_arm, MC_put_x_8_arm in libmpeg2/motion_comp_arm_s.S have addresses in .text, which is bad for shared libraries. Some environments demand that .text actually be read-only all the time, yet MC_put_o_16_arm etc require that the addresses be modified by the dynamic linking mechanism (dlopen, LoadLibrary, etc.) Even in those environments which permit the dynamic linker to modify the .text segment, the runtime cost of doing the relocation can be noticeable. This commit rewrites the linkage, discarding the tables of addresses in favor of tables of offsets. All transfers are local within each individual function, so there can be no interference by processing that occurs after assembly, such as link-time re-ordering (even of individual functions.)

r1200 | walken | 2008-10-10 14:11:36 +0200 (Fri, 10 Oct 2008) | 9 lines Changed paths: M /trunk/libmpeg2/header.c M /trunk/libmpeg2/mpeg2_internal.h M /trunk/libmpeg2/slice.c First step towards decoupling the slice decoder (which is the main CPU intensive part of libmpeg2) from the rest of the decoder (i.e. the chunk gathering, header parsing and state machine). Eventually I want to get to a point where decode.c and header.c do not know about the internals of the mpeg2_decoder_t type. Longer term, I want to be able to switch the slice decoders, for example to support GPU acceleration. |

Here is a patch to update the license headers in libmpeg2 to reflect that change. It also includes a similar change for the COPYING file. I just replaced yours with the copy in /usr/share/common-licenses/GPL-2 on my Debian system. |
