gh-119689: generate stack effect metadata for pseudo instructions (#119691) 2024-05-29 09:47:56 +00:00

gh-118335: Configure Tier 2 interpreter at build time (#118339) 
The code for Tier 2 is now only compiled when configured
with `--enable-experimental-jit[=yes|interpreter]`.

We drop support for `PYTHON_UOPS` and -`Xuops`,
but you can disable the interpreter or JIT
at runtime by setting `PYTHON_JIT=0`.
You can also build it without enabling it by default
using `--enable-experimental-jit=yes-off`;
enable with `PYTHON_JIT=1`.

On Windows, the `build.bat` script supports
`--experimental-jit`, `--experimental-jit-off`,
`--experimental-interpreter`.

In the C code, `_Py_JIT` is defined as before
when the JIT is enabled; the new variable
`_Py_TIER2` is defined when the JIT *or* the
interpreter is enabled. It is actually a bitmask:
1: JIT; 2: default-off; 4: interpreter.

gh-117323: Make `cell` thread-safe in free-threaded builds (#117330) 
Use critical sections to lock around accesses to cell contents. The critical sections are no-ops in the default (with GIL) build.

GH-116422: Tier2 hot/cold splitting (GH-116813) 
Splits the "cold" path, deopts and exits, from the "hot" path, reducing the size of most jitted instructions, at the cost of slower exits.

gh-115778: Add `tierN` annotation for instruction definitions (#115815) 
This replaces the old `TIER_{ONE,TWO}_ONLY` macros. Note that `specialized` implies `tier1`.
