SPARC(Scalable Processor Architecture) Sun Microsystems's specific CPU.

SPARC is a RISC instruction set architecture (ISA) developed by Sun Microsystems (now merged into Oracle), introduced in mid-1987.

SPARC hardware often runs Solaris, the Unix operating system, but other OSes run on SPARC hardware, and runs on more than just SPARC hardware.

SPARC doesn't allow unaligned loads, so SIGBUS (bus error) faults are a common problem when porting C or C++ to SPARC from x86 (for example).

In assembly, SPARC's 32 architectural registers are a sliding window onto a virtual register file. The save instruction that slides the window might or might not spill to memory, depending on whether the CPU microarchitecture is out of registers when it runs.

SPARC register names to binary

So in SPARC V8, the destination register (rd) occupies 5 bits of the instruction (25th-29th). My question is: is there a document with map associating each register name, say %i1, to its respective 5-bit binary, say, 01010? I can't find such…
