it's not so much that i'm unfamiliar with them

it was why i loved the 68k assembler language... 8x32bit address and 8x32 bit data registers on a 16 bit processor

the Power series, the successors to the 68k included "register files" and we now also see that the x86 family has AVX, AVX2 and AVX512, which big fat registers, named after how big their registers are (256 and 512 bits)

these registers are famously associated with the *bleed exploits, because some genius had the idea to not zero them but instead have a "it's zero" bitflag that exploits were bypassing by just copying the register to a memory location

*shakes head*

pretty sure this same retarded error has been made repeatedly, and happened before the "register file" spate of x86, that someone already made this engineering mistake in prior register machines

just some history about register machines for you

they are the best

it's why i hated the x86 so much and why it made me so sad when everyone ditched motorola's processors, because motorola went the register machine path
