x86inc: Prefer r14/r15 over r12/r13 on x86-64 Due to a peculiarity in the ModR/M addressing encoding, the r12 and r13 registers sometimes requires an additional byte when used as a base register. r14 and r15 doesn't have that issue, so prefer using them. > http://git.videolan.org/gitweb.cgi/ffmpeg.git/?a=commit;h=cd4ca8245963c6c1845a87b658822b0be0c99048 --- libavutil/x86/x86inc.asm | 16 ++++++++-------- 1 file changed, 8 insertions(+), 8 deletions(-) diff --git a/libavutil/x86/x86inc.asm b/libavutil/x86/x86inc.asm index bb1b1be191..122dc30b54 100644 --- a/libavutil/x86/x86inc.asm +++ b/libavutil/x86/x86inc.asm @@ -426,10 +426,10 @@ DECLARE_REG 7, rdi, 64 DECLARE_REG 8, rsi, 72 DECLARE_REG 9, rbx, 80 DECLARE_REG 10, rbp, 88 -DECLARE_REG 11, R12, 96 -DECLARE_REG 12, R13, 104 -DECLARE_REG 13, R14, 112 -DECLARE_REG 14, R15, 120 +DECLARE_REG 11, R14, 96 +DECLARE_REG 12, R15, 104 +DECLARE_REG 13, R12, 112 +DECLARE_REG 14, R13, 120 %macro PROLOGUE 2-5+ 0 ; #args, #regs, #xmm_regs, [stack_size,] arg_names... %assign num_args %1 @@ -530,10 +530,10 @@ DECLARE_REG 7, R10, 16 DECLARE_REG 8, R11, 24 DECLARE_REG 9, rbx, 32 DECLARE_REG 10, rbp, 40 -DECLARE_REG 11, R12, 48 -DECLARE_REG 12, R13, 56 -DECLARE_REG 13, R14, 64 -DECLARE_REG 14, R15, 72 +DECLARE_REG 11, R14, 48 +DECLARE_REG 12, R15, 56 +DECLARE_REG 13, R12, 64 +DECLARE_REG 14, R13, 72 %macro PROLOGUE 2-5+ ; #args, #regs, #xmm_regs, [stack_size,] arg_names... %assign num_args %1 _______________________________________________ ffmpeg-cvslog mailing list ffmpeg-cvslog@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-cvslog
