* gh-109979: Unify _GUARD_TYPE_VERSION{,_STORE} (#110301)Guido van Rossum2023-10-03
| | | | | Now the target for `DEOPT_IF()` is auto-filled, we don't need a separate `_GUARD_TYPE_VERSION_STORE` uop.
* gh-109979: Auto-generate the target for DEOPT_IF() (#110193)Guido van Rossum2023-10-03
| | | | | | | | | | | | | | | | In Python/bytecodes.c, you now write ``` DEOPT_IF(condition); ``` The code generator expands this to ``` DEOPT_IF(condition, opcode); ``` where `opcode` is the name of the unspecialized instruction. This works inside macro expansions too. **CAVEAT:** The entire `DEOPT_IF(condition)` statement must be on a single line. If it isn't, the substitution will fail; an error will be printed by the code generator and the C compiler will report some errors.

* gh-104909: Split some more insts into ops (#109943)Guido van Rossum2023-09-27
| | | | | | | | | | | | | | | | | | | | These are the most popular specializations of `LOAD_ATTR` and `STORE_ATTR` that weren't already viable uops: * Split LOAD_ATTR_METHOD_WITH_VALUES * Split LOAD_ATTR_METHOD_NO_DICT * Split LOAD_ATTR_SLOT * Split STORE_ATTR_SLOT * Split STORE_ATTR_INSTANCE_VALUE Also: * Add `-v` flag to code generator which prints a list of non-viable uops (easter-egg: it can print execution counts -- see source) * Double _Py_UOP_MAX_TRACE_LENGTH to 128 I had dropped one of the DEOPT_IF() calls! :-(

* gh-109039: Branch prediction for Tier 2 interpreter (#109038)Guido van Rossum2023-09-11
| | | | | | | | | | | This adds a 16-bit inline cache entry to the conditional branch instructions POP_JUMP_IF_{FALSE,TRUE,NONE,NOT_NONE} and their instrumented variants, which is used to keep track of the branch direction. Each time we encounter these instructions we shift the cache entry left by one and set the bottom bit to whether we jumped. Then when it's time to translate such a branch to Tier 2 uops, we use the bit count from the cache entry to decided whether to continue translating the "didn't jump" branch or the "jumped" branch. The counter is initialized to a pattern of alternating ones and zeros to avoid bias. The .pyc file magic number is updated. There's a new test, some fixes for existing tests, and a few miscellaneous cleanups.

* 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`.

* GH-104909: Move unused cache entries from uops to macros (#107444)Guido van Rossum2023-07-31
| | | | | | 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.
