* gh-106581: Split CALL_BOUND_METHOD_EXACT_ARGS into uops (#108462)Guido van Rossum2023-08-24
| | | Instead of using `GO_TO_INSTRUCTION(CALL_PY_EXACT_ARGS)` we just add the macro elements of the latter to the macro for the former. This requires lengthening the uops array in struct opcode_macro_expansion. (It also required changes to stacking.py that were merged already.)
* gh-106581: Project through calls (#108067)Guido van Rossum2023-08-17
| | | | This finishes the work begun in gh-107760. When, while projecting a superblock, we encounter a call to a short, simple function, the superblock will now enter the function using `_PUSH_FRAME`, continue through it, and leave it using `_POP_FRAME`, and then continue through the original code. Multiple frame pushes and pops are even possible. It is also possible to stop appending to the superblock in the middle of a called function, when running out of space or encountering an unsupported bytecode.

* gh-106581: Split `CALL_PY_EXACT_ARGS` into uops (#107760)Guido van Rossum2023-08-16
| | | | | | | | | | | | * Split `CALL_PY_EXACT_ARGS` into uops This is only the first step for doing `CALL` in Tier 2. The next step involves tracing into the called code object and back. After that we'll have to do the remaining `CALL` specialization. Finally we'll have to deal with `KW_NAMES`. Note: this moves setting `frame->return_offset` directly in front of `DISPATCH_INLINED()`, to make it easier to move it into `_PUSH_FRAME`.

| | | | | | There's no need to use a dummy uop to skip unused cache entries. The macro syntax lets you write `unused/1` instead. Similarly, move `unused/5` from op `_LOAD_ATTR_INSTANCE_VALUE` to macro `LOAD_ATTR_INSTANCE_VALUE`.

* gh-106581: Add 10 new opcodes by allowing `assert(kwnames == NULL)` (#106707)Guido van Rossum2023-07-17
| | | | | | | | | | | | | By turning `assert(kwnames == NULL)` into a macro that is not in the "forbidden" list, many instructions that formerly were skipped because they contained such an assert (but no other mention of `kwnames`) are now supported in Tier 2. This covers 10 instructions in total (all specializations of `CALL` that invoke some C code): - `CALL_NO_KW_TYPE_1` - `CALL_NO_KW_STR_1` - `CALL_NO_KW_TUPLE_1` - `CALL_NO_KW_BUILTIN_O` - `CALL_NO_KW_BUILTIN_FAST` - `CALL_NO_KW_LEN` - `CALL_NO_KW_ISINSTANCE` - `CALL_NO_KW_METHOD_DESCRIPTOR_O` - `CALL_NO_KW_METHOD_DESCRIPTOR_NOARGS` - `CALL_NO_KW_METHOD_DESCRIPTOR_FAST`

* gh-106529: Fix subtle Tier 2 edge case with list iterator (#106756)Guido van Rossum2023-07-14
| | | | | | | | | | | | The Tier 2 opcode _IS_ITER_EXHAUSTED_LIST (and _TUPLE) didn't set it->it_seq to NULL, causing a subtle bug that resulted in test_exhausted_iterator in list_tests.py to fail when running all tests with -Xuops. The bug was introduced in gh-106696. Added this as an explicit test. Also fixed the dependencies for ceval.o -- it depends on executor_cases.c.h.
* gh-106529: Split FOR_ITER_{LIST,TUPLE} into uops (#106696)Guido van Rossum2023-07-13

* gh-106701: Move the hand-written Tier 2 uops to bytecodes.c (#106702)Guido van Rossum2023-07-13
| | | | | | | This moves EXIT_TRACE, SAVE_IP, JUMP_TO_TOP, and _POP_JUMP_IF_{FALSE,TRUE} from ceval.c to bytecodes.c. They are no less special than before, but this way they are discoverable o the copy-and-patch tooling.

* gh-104584: Fix error handling from backedge optimization (#106484)Guido van Rossum2023-07-06
| | | | | | | | | | | | When `_PyOptimizer_BackEdge` returns `NULL`, we should restore `next_instr` (and `stack_pointer`). To accomplish this we should jump to `resume_with_error` instead of just `error`. The problem this causes is subtle -- the only repro I have is in PR gh-106393, at commit d7df54b139bcc47f5ea094bfaa9824f79bc45adc. But the fix is real (as shown later in that PR). While we're at it, also improve the debug output: the offsets at which traces are identified are now measured in bytes, and always show the start offset. This makes it easier to correlate executor calls with optimizer calls, and either with `dis` output. <!-- gh-issue-number: gh-104584 --> * Issue: gh-104584 <!-- /gh-issue-number -->

* gh-104584: Baby steps towards generating and executing traces (#105924)Guido van Rossum2023-06-26
| | | | | Added a new, experimental, tracing optimizer and interpreter (a.k.a. "tier 2"). This currently pessimizes, so don't use yet -- this is infrastructure so we can experiment with optimizing passes. To enable it, pass ``-Xuops`` or set ``PYTHONUOPS=1``. To get debug output, set ``PYTHONUOPSDEBUG=N`` where ``N`` is a debug level (0-4, where 0 is no debug output and 4 is excessively verbose). All of this code is likely to change dramatically before the 3.13 feature freeze. But this is a first step.
