[SMDOC] WebAssembly baseline compiler (RabaldrMonkey)
For now, see WasmBCClass.h for general comments about the compiler's
structure.
----------------
General assumptions for 32-bit vs 64-bit code:
- A 32-bit register can be extended in-place to a 64-bit register on 64-bit
systems.
- Code that knows that Register64 has a '.reg' member on 64-bit systems and
'.high' and '.low' members on 32-bit systems, or knows the implications
thereof, is #ifdef JS_PUNBOX64. All other code is #if(n)?def JS_64BIT.
Coding standards are a little fluid:
- In "small" code generating functions (eg emitMultiplyF64, emitQuotientI32,
and surrounding functions; most functions fall into this class) where the
meaning is obvious:
Old school:
- if there is a single source + destination register, it is called 'r'
- if there is one source and a different destination, they are called 'rs'
and 'rd'
- if there is one source + destination register and another source register
they are called 'r' and 'rs'
- if there are two source registers and a destination register they are
called 'rs0', 'rs1', and 'rd'.
The new thing:
- what is called 'r' in the old-school naming scheme is increasingly called
'rsd' in source+dest cases.
- Generic temp registers are named /temp[0-9]?/ not /tmp[0-9]?/.
- Registers can be named non-generically for their function ('rp' for the
'pointer' register and 'rv' for the 'value' register are typical) and those
names may or may not have an 'r' prefix.
- "Larger" code generating functions make their own rules.

[SMDOC] WebAssembly code rules (evolving)
TlsContext.get() is only to be invoked from functions that have been invoked
_directly_ by generated code as cold(!) Builtin calls, from code that is
only used by signal handlers, or from helper functions that have been
called _directly_ from a simulator. All other code shall pass in a
JSContext* to functions that need it, or an Instance* or TlsData* since the
context is available through them.
Code that uses TlsContext.get() shall annotate each such call with the
reason why the call is OK.
