[LLVMdev] Asm syntax of Mips m[tf]cX coprocessor instructions
...ome Mips code which is normally built
with a gcc cross toolchain with clang instead. This code targets the
Cavium Octeon, and uses some of that CPU's crypto engine features which
are implemented in coprocessor 2.
The inline asm for the crypto code uses instructions of the form "dmtc2
%0, 0xNNNN" - that is the coprocessor register is represented as a
constant, which is the only syntax that gas seems to accept
(specifically, an expression which evaluates to a constant). Clang's
integrated-as, however, only accepts "dmtc2 %0, $0xNNNN", that is, a
coprocessor register numb...

Finding scratch register after function call
For a Z80 backend, "eliminateCallFramePseudoInstr()" shall adjust the
stack pointer in three possible ways, e.g. after a function call,
depending on the amount (= adjustment size) *and some other rules*:
1. via one or more target "pop <reg>" instructions (SP increments +2 per
instruction), using an unused reg (disregarding the contents after the
operation), followed

unix registry command
...- regcreatekey parentkeyname subkeyname
creates a key with _default_ permissions. cannot specify key permissions
at the moment.
- regcreateval parentkeyname valuename [1|3|4] value.
1=UNICODE string;
3=hex data (value is of format 0095a439 or 00,15,39,28,ba,ff etc)
4=DWORD (value is of format 0xNNNN or NNNN)
that's all, for now: there are improvements to be made and more commands
to add. have fun, and BE CAREFUL.
