- fix inverted shift direction in MBL() and MBR() macro in BE case (used by GETBITS() and PUTBITS() in copycols() function in rasops_bitops.h) - make all bitmask values unsigned and use proper uint32_t types for bitmap variables (to avoid arithmetic right shift) - fix various botches in right-to-left copy op (logic is taken from hp300) Tested on bwtwo(4) on NetBSD/sparc.

This directory contains `rasops', a set of raster operations intended to
|
|
replace the dev/rcons/raster stuff for both wscons and rcons. It yields
|
|
significantly improved performance, supports multiple depths and color.
|
|
|
|
Issues/TODO:
|
|
|
|
- There is no generic `putchar' function for 2bpp
|
|
- Color handling for 2bpp is broken
|
|
- 64-bit types are not used on machines that are 64-bit
|
|
- We should never be doing reads/writes of less than 32-bits
|
|
- Flags in attribute values are hardcoded
|
|
- Need a manpage
|
|
- Should handle multiple fonts simulatneously
|
|
- Generate an `empty' box character when we have no match?
|
|
- Use 'int' in lieu of 'int32' where we can
|
|
- Compress some cases in rasops1.c
