Warn when the following are used without the appropriate cpuflag: * YMM and ZMM registers * 'pextrw' with a memory operand * GPR instruction set extensions
-
Allows for marking symbols as having limited global scope, similar to using 'hidden' symbol visibility on ELF.

-
Allows for automatic command line completion for both options and values. Options such as --input-csp and --input-fmt will dynamically retrieve supported values from libavformat when compiled with lavf support. Execute 'source tools/bash-autocomplete.sh' in bash to enable.

Progressive High, Constrained High, and Progressive High 10. Even in Main profile, constraint_set4_flag is now set to 1 if progressive, and constraint_set5_flag is set to 1 if no B-slices are present.

Around a ~1% speedup to the overall encoding for --slow.
-
No overall speedup, just tidier code.
-
Seems to give about a 1-2% overall speedup on --slow.

Around a ~2% speedup to the overall encoding for --slow.

Yet another use of xxpermdi, another 10% gain.
-
About 20% faster.
-
Now 4x4 is as slow as C and 4x8 is a 2% faster than before.
-
And use it on the other satd > 8. 5-10% faster depending on the size.
-
10% faster.
-
4x faster than C.

Most x86-64 operating systems nowadays doesn't even allow .text relocations in object files any more, and there is no measurable overall performance difference from using RIP-relative addressing in x264 asm. Enforcing PIC reduces complexity and simplifies testing.

Also check that CQP mode is not used with 2-pass.
-
Ensures that access is atomic and that other threads sees the actual value of the variable.

Also fix the string parsing in param_apply_tune() to correctly compare the entire string, not just the first N characters.

1) using xxpermdi + merge instead of 2 merges improves quant_8x8 performance by 5% 2) use vec_splats instead of vec_splat checkasm timings when compiled with gcc: C: AltiVec: before: after: quant_2x2_dc: 57 163 46 quant_4x4_dc: 141 162 57 dequant_4x4_cmp: 104 101 45 dequant_4x4_flat: 104 106 46 dequant_8x8_cmp: 412 208 147 dequant_8x8_flat: 414 212 149 -
Increases overall encoding speed on POWER9 by 8%.
