   @lkundrak @q66 Can't say anything about the rest, but

   Hardware-wise, yes, technially all SPARCs are bi-endian
   You can set PSTATE.cle and PSTATE.tle to 1 and from that point on your processor should effectively become LE

   However, all instruction words are to be encoded in BE, even when the CPU runs in LE mode :akkoderp:

   Aside from that, there are variants of loads and stores that take explicit endianness parameter, and atomic CAS instructions always require endianness to be supplied explicitly

     @koakuma @q66 omg, is there an actual little-endian sparc? (all i knew is that memory loads and stores can be little endian and that's about it)

     but also -- my assumption was that people do little endian variants just because a lot of software is written assuming little endian due to x86 prevalence. the same reasoning doesn't really apply the other way

     but that is of course, an assumption. i've been wrong before...

     @lkundrak @q66 The same reason as to why people do little endian SPARC :02lurk:

     @koakuma @q66 do you know what is the use for it (either BE riscv or arm)?

     @q66 There'll be RISC-V big endian too dw :akkoderp:
