GH-98831: Implement array support in cases generator (#100912) 
You can now write things like this:
```
inst(BUILD_STRING, (pieces[oparg] -- str)) { ... }
inst(LIST_APPEND, (list, unused[oparg-1], v -- list, unused[oparg-1])) { ... }
```
Note that array output effects are only partially supported (they must be named `unused` or correspond to an input effect).

GH-98831: Identify instructions that don't use oparg (#100957)

GH-98831: Add some tests for generate_cases.py (#100763) 
- This doesn't cover everything (far from it) but it's a start.
- This uses pytest, which isn't ideal, but was quickest to get started.

GH-98831: Update generate_cases.py: register inst, opcode_metadata.h (#100735) 
(These aren't used yet, but may be coming soon,
and it's easier to keep this tool the same between branches.)

Added a sanity check for all this to compile.c.

GH-99770: Make the correct call specialization fail kind show up in the stats (GH-99771) 2022-12-22 12:44:59 +00:00

GH-98831: Add DECREF_INPUTS(), expanding to DECREF() each stack input (#100205) 
The presence of this macro indicates that a particular instruction
may be considered for conversion to a register-based format
(see https://github.com/faster-cpython/ideas/issues/485).

An invariant (currently unchecked) is that `DEOPT_IF()` may only
occur *before* `DECREF_INPUTS()`, and `ERROR_IF()` may only occur
*after* it. One reason not to check this is that there are a few
places where we insert *two* `DECREF_INPUTS()` calls, in different
branches of the code. The invariant checking would have to be able
to do some flow control analysis to understand this.

Note that many instructions, especially specialized ones,
can't be converted to use this macro straightforwardly.
This is because the generator currently only generates plain
`Py_DECREF(variable)` statements, and cannot generate
things like `_Py_DECREF_SPECIALIZED()` let alone deal with
`_PyList_AppendTakeRef()`.

gh-81057: Move _Py_RefTotal to the "Ignored Globals" List (gh-100203) 
We can't move it to _PyRuntimeState because the symbol is exposed in the stable ABI. We'll have to sort that out before a per-interpreter GIL, but it shouldn't be too hard.
