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.) + +Patch by John Reiser <jreiser@bitwagon.com> +Signed-off-by: Khem Raj <raj.khem@gmail.com> +Upstream-Status: Backport [https://code.videolan.org/videolan/libmpeg2/commit/946bf4b518aacc224f845e73708f99e394744499] +--- + libmpeg2/motion_comp_arm_s.S | 70 +++++++++++++++++------------------- + 1 file changed, 33 insertions(+), 37 deletions(-) + +diff --git a/libmpeg2/motion_comp_arm_s.S b/libmpeg2/motion_comp_arm_s.S +index c921f7c..82143f8 100644 +--- a/libmpeg2/motion_comp_arm_s.S ++++ b/libmpeg2/motion_comp_arm_s.S +@@ -30,9 +30,13 @@ MC_put_o_16_arm: + pld [r1] + stmfd sp!, {r4-r11, lr} @ R14 is also called LR + and r4, r1, #3 +- adr r5, MC_put_o_16_arm_align_jt +- add r5, r5, r4, lsl #2 +- ldr pc, [r5] ++ ldrb r4, [pc, r4] ++ add pc, pc, r4, lsl #2 ++ .byte (MC_put_o_16_arm_align0 -
