BBC BASIC for SDL 2.0 v0.27a released

Post by Richard Russell » Sat Dec 01, 2018 3:57 pm

I have released version 0.27a of BBC BASIC for SDL 2.0 (BBCSDL), for full details see the announcement here. Of particular interest may be that the 'experimental' 64-bit Linux edition now includes a reasonably complete x86-64 assembler. It supports floating point, SSE, SSE2 and SSE3 instructions (more than 500 mnemonics in all) but not SSSE3, SSE4 or AVX instructions (so the YMM and ZMM registers are not directly accessible) nor instructions that require kernel privilege. I have also omitted the legacy 32-bit addressing modes because they are not useful in the 64-bit flat addressing space of BBCSDL. You can of course synthesise any instruction using DB directives.
