Fix: inconsistent description for 32bpp-sse4-anim blitter (#7740) 2019-09-14 16:52:35 +02:00
Henry Wilson 7c8e7c6b6e Codechange: Use null pointer literal instead of the NULL macro 2019-04-10 23:22:20 +02:00
Henry Wilson af7d9020a1 Codechange: Use override specifer for overriding member declarations 
This is a C++11 feature that allows the compiler to check that a virtual
member declaration overrides a base-class member with the same signature.

Also src/blitter/32bpp_anim_sse4.hpp +38 is no longer erroneously marked
as virtual despite being a template.

Jonathan G Rennison 4b256fed36 Codechange: [Blitter] Adjust line-drawing algorithm to reduce wasted off-screen work 
This clips the line segment to be within the screen area prior to pixel iteration.

Jonathan G Rennison 0240e90169 Fix: [Blitter] Avoid signed overflow when drawing long lines 2019-01-24 11:12:06 +00:00
Jonathan G Rennison db924a4681 Codechange: [Blitter] Change DrawLine to be templated 
This is remove per-pixel overheads due to use of the SetPixel virtual
method.
These overheads included:
* expensive virtual method call which prevents inlining
* palette lookup for every pixel
* branch on whether palette animation is enabled on every pixel

Regenerate project files.

Charles Pigott 5f86e1a390 Codechange: Silence -Wclass-memaccess warnings with GCC8 2018-06-27 22:54:46 +02:00
Jonathan G Rennison 17257b9620 Add: 32bpp SSE2 blitter palette animator (#6795) 
Create a new blitter mode: 32bpp-sse2-anim, which is 32bpp-anim + this.
32bpp-sse2-anim is now used by default where 32bpp-anim would have been.
Also use this with the 32bpp-sse4-anim blitter.

See issue #6469.
