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 - 0f)>>2 -+ .byte (MC_put_o_16_arm_align1 - 0f)>>2 -+ .byte (MC_put_o_16_arm_align2 - 0f)>>2 -+ .byte (MC_put_o_16_arm_align3 - 0f)>>2 -+0: - - MC_put_o_16_arm_align0: - ldmia r1, {r4-r7} -@@ -76,11 +80,6 @@ MC_put_o_16_arm_align3: - 1: PROC(24) - bne 1b - ldmfd sp!, {r4-r11, pc} @@ update PC with LR content. --MC_put_o_16_arm_align_jt: -- .word MC_put_o_16_arm_align0 -- .word MC_put_o_16_arm_align1 -- .word MC_put_o_16_arm_align2 -- .word MC_put_o_16_arm_align3 - - @ ---------------------------------------------------------------- - .align -@@ -91,9 +90,14 @@ MC_put_o_8_arm: - pld [r1] - stmfd sp!, {r4-r10, lr} @ R14 is also called LR - and r4, r1, #3 -- adr r5, MC_put_o_8_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_8_arm_align0 - 0f)>>2 -+ .byte (MC_put_o_8_arm_align1 - 0f)>>2 -+ .byte (MC_put_o_8_arm_align2 - 0f)>>2 -+ .byte (MC_put_o_8_arm_align3 - 0f)>>2 -+0: -+ - MC_put_o_8_arm_align0: - ldmia r1, {r4-r5} - add r1, r1, r2 -@@ -135,12 +139,6 @@ MC_put_o_8_arm_align3: - bne 1b - ldmfd sp!, {r4-r10, pc} @@ update PC with LR content. - --MC_put_o_8_arm_align_jt: -- .word MC_put_o_8_arm_align0 -- .word MC_put_o_8_arm_align1 -- .word MC_put_o_8_arm_align2 -- .word MC_put_o_8_arm_align3 -- - @ ---------------------------------------------------------------- - .macro AVG_PW rW1, rW2 - mov \rW2, \rW2, lsl #24 -@@ -160,12 +158,17 @@ MC_put_x_16_arm: - @@ void func(uint8_t * dest, const uint8_t * ref, int stride, int height) - pld [r1] - stmfd sp!, {r4-r11,lr} @ R14 is also called LR -+ ldr r11, 0f - and r4, r1, #3 -- adr r5, MC_put_x_16_arm_align_jt -- ldr r11, [r5] - mvn r12, r11 -- add r5, r5, r4, lsl #2 -- ldr pc, [r5, #4] -+ ldrb r4, [pc, r4] -+ add pc, pc, r4, lsl #2 -+ .byte (MC_put_x_16_arm_align0 - 0f)>>2 -+ .byte (MC_put_x_16_arm_align1 - 0f)>>2 -+ .byte (MC_put_x_16_arm_align2 - 0f)>>2 -+ .byte (MC_put_x_16_arm_align3 - 0f)>>2 -+0: -+ .word 0x01010101 - - .macro ADJ_ALIGN_QW shift, R0, R1, R2, R3, R4 - mov \R0, \R0, lsr #(\shift) -@@ -238,12 +241,6 @@ MC_put_x_16_arm_align3: - add r0, r0, r2 - bne 1b - ldmfd sp!, {r4-r11,pc} @@ update PC with LR content. --MC_put_x_16_arm_align_jt: -- .word 0x01010101 -- .word MC_put_x_16_arm_align0 -- .word MC_put_x_16_arm_align1 -- .word MC_put_x_16_arm_align2 -- .word MC_put_x_16_arm_align3 - - @ ---------------------------------------------------------------- - .align -@@ -253,12 +250,17 @@ MC_put_x_8_arm: - @@ void func(uint8_t * dest, const uint8_t * ref, int stride, int height) - pld [r1] - stmfd sp!, {r4-r11,lr} @ R14 is also called LR -+ ldr r11, 0f - and r4, r1, #3 -- adr r5, MC_put_x_8_arm_align_jt -- ldr r11, [r5] - mvn r12, r11 -- add r5, r5, r4, lsl #2 -- ldr pc, [r5, #4] -+ ldrb r4, [pc, r4] -+ add pc, pc, r4, lsl #2 -+ .byte (MC_put_x_8_arm_align0 - 0f)>>2 -+ .byte (MC_put_x_8_arm_align1 - 0f)>>2 -+ .byte (MC_put_x_8_arm_align2 - 0f)>>2 -+ .byte (MC_put_x_8_arm_align3 - 0f)>>2 -+0: -+ .word 0x01010101 - - .macro ADJ_ALIGN_DW shift, R0, R1, R2 - mov \R0, \R0, lsr #(\shift) -@@ -319,9 +321,3 @@ MC_put_x_8_arm_align3: - add r0, r0, r2 - bne 1b - ldmfd sp!, {r4-r11,pc} @@ update PC with LR content. --MC_put_x_8_arm_align_jt: -- .word 0x01010101 -- .word MC_put_x_8_arm_align0 -- .word MC_put_x_8_arm_align1 -- .word MC_put_x_8_arm_align2 -- .word MC_put_x_8_arm_align3 |
