* Better compilation of arguments to `ignore`Mattias Engdegård2023-04-12
| | | | | | | | | | * lisp/emacs-lisp/bytecomp.el (byte-compile-form) (byte-compile-ignore): Instead of compiling each `ignore` argument for value which is then immediately discarded, compile it for effect but suppress ignore-return-value warnings by passing the special value `for-effect-no-warn` as for-effect parameter. Proposed by Stefan Monnier.
* Extend ignored-return-value warning to more functions (bug#61730)Mattias Engdegård2023-04-09
| | | | | | | | | | | | | | | | | | | Warn when the return value of certain functions is unused. Previously this was only done for side-effect-free functions, and for `mapcar`. These are functions where the return value is important for correct usage or where ignoring it is likely to indicate a mistake. The exact set of functions is tentative and will be modified as we gain a better understanding of which ones to include. The current set comprises higher order functions such as `mapcar` which are not primarily called for the effects of their function arguments, and list-mutating functions like `nreverse` whose return value is essential. * lisp/emacs-lisp/bytecomp.el (byte-compile-form): Add list of functions to warn about when their value is ignored. * etc/NEWS: Announce.
* Consolidate existing warnings about unused return valuesMattias Engdegård2023-04-08
| | | | | | | | | | | | | | | | | | | | | | | | | Move the warning about unused return values from calls to side-effect-free functions from the source-level optimiser to the code generator, where it can be unified with the special-purpose warning about unused values from `mapcar`. This change also cures spurious duplicate warnings about the same code, makes the warnings amenable to suppression through `with-suppressed-warnings`, and now warns about some unused values that weren't caught before. * lisp/emacs-lisp/byte-opt.el (byte-optimize-form-code-walker): Move warning away from here. * lisp/emacs-lisp/byte-run.el (with-suppressed-warnings): * lisp/emacs-lisp/bytecomp.el (byte-compile-warnings): Doc string updates. (byte-compile-form): Put the new warnings here. (byte-compile-normal-call): Move mapcar warning away from here. * lisp/emacs-lisp/bytecomp.el (byte-compile-ignore): Compile args to `ignore` for value to avoid unused-value warnings, and then discard the generated values immediately thereafter. Mostly this does not affect the generated code but in rare cases it might result in slightly worse code. * test/lisp/emacs-lisp/bytecomp-tests.el (bytecomp-test--with-suppressed-warnings): Adapt test.
* Repair and speed up safe-copy-tree and make it internal (bug#61962)Mattias Engdegård2023-03-12
| | | | | | | | | | | | | | | | There is no particular requirement for safe-copy-tree so let's make it internal for now.

* Fix `cond` miscompilation bugMattias Engdegård2023-03-02
| | | | | | | | | | | | | | | This fixes a bug that miscompiled (cond ... C S1...Sn) where S1...Sn are switch clauses (that can be compiled into a switch op) and C a non-switch clause, by tucking on an extra copy of C at the end. This was a serious wrong-code bug when the condition of C had side-effects; otherwise it was only a waste of time and space. * lisp/emacs-lisp/bytecomp.el (byte-compile-cond): Fix. * test/lisp/emacs-lisp/bytecomp-tests.el (bytecomp-tests--test-cases): Add test case.
* More accurate suppression of ignored return value warningMattias Engdegård2023-02-24
| | | | | | | | * lisp/emacs-lisp/bytecomp.el (byte-compile-file-form-defalias): Be careful to propagate the for-effect mode through a `with-suppressed-warnings` form when compiling, so that a form inside isn't erroneously considered to have its value 'used' by the surrounding warning suppression form itself.
* Remove stray quotesMattias Engdegård2023-02-21
| | | | | | | * lisp/emacs-lisp/bytecomp.el (byte-compile-form): * lisp/help-fns.el (help-fns--interactive-only): Fix obvious mistake. Since `interactive-only` is not supposed to be anything other than a symbol at these points it was not a very consequential bug.
* Follow aliases for `interactive-only` declarationsMattias Engdegård2023-02-21
| | | | | | | | | | Make `interactive-only` declarations apply to aliases of the same function as well since this quality isn't in the name but in what the function does. * lisp/emacs-lisp/bytecomp.el (byte-compile-form): * lisp/help-fns.el (help-fns--interactive-only): Follow aliases when retrieving the `interactive-only` property.
* Make the byte compiler give correct warning positions in eval-and-compileAlan Mackenzie2023-02-17
| | | | | | | | This fixes bug #61579. * lisp/emacs-lisp/bytecomp.el (byte-compile-initial-environment): Remove a spurious `byte-run-strip-symbol-position' from the core form of the eval-and-compile element.
* Better commutative binary numerical op codegenMattias Engdegård2023-01-29
| | | | | | | * lisp/emacs-lisp/bytecomp.el (byte-compile-variadic-numeric): Put a constant argument last for better LAP code opportunities. This applies to commutative binary operations (+ and *). `min` and `max` are not included being not quite commutative.
* Better compilation of n-ary comparisonsMattias Engdegård2023-01-29
| | | | | | | | | | | | | | | | | | | | | | Transform n-ary comparisons to a chain of binary comparisons in the Lisp optimiser instead of in codegen, to allow for subsequent optimisations. This generalises the transform, so that (< 1 X 10) -> (let ((x X)) (and (< 1 x) (< x 10))) where (< 1 x) is then flipped to (> x 1) in codegen since it's slightly more efficient to have the constant argument last. Arguments that are neither constants nor variables are given temporary bindings. This results in about 2× speedup for 3-ary comparisons of fixnums with nontrivial arguments, and also improves the code slightly for binary comparisons with a constant first argument. * lisp/emacs-lisp/byte-opt.el (byte-opt--nary-comparison): New, set as the `byte-optimizer` property for =, <, <=, >, and >=. * lisp/emacs-lisp/bytecomp.el (byte-compile-and-folded): Rename to... (byte-compile-cmp): ...and rewrite.

| * (Ffunction): Make interpreted closures safe for spaceStefan Monnier2022-10-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Interpreted closures currently just grab a reference to the complete lexical environment, so (lambda (x) (+ x y)) can end up looking like (closure ((foo ...) (y 7) (bar ...) ...) (x) (+ x y)) where the foo/bar/... bindings are not only useless but can prevent the GC from collecting that memory (i.e. it's a representation that is not "safe for space") and it can also make that closure "unwritable" (or more specifically, it can cause the closure's print representation to be u`read`able). Compiled closures don't suffer from this problem because `cconv.el` actually looks at the code and only stores in the compiled closure those variables which are actually used. So, we fix this discrepancy by letting the existing code in `cconv.el` tell `Ffunction` which variables are actually used by the body of the function such that it can filter out the irrelevant elements and return a closure of the form: (closure ((y 7)) (x) (+ x y)) * lisp/loadup.el: Preload `cconv` and set `internal-filter-closure-env-function` once we have a usable `cconv-fv`. * lisp/emacs-lisp/bytecomp.el (byte-compile-preprocess): Adjust to new calling convention of `cconv-closure-convert`. (byte-compile-not-lexical-var-p): Delete function, moved to `cconv.el`. (byte-compile-bind): Use `cconv--not-lexical-var-p`. * lisp/emacs-lisp/cconv.el (cconv--dynbound-variables): New var. (cconv-closure-convert): New arg `dynbound-vars` (cconv--warn-unused-msg): Remove special case for `ignored`, so we don't get confused when a function uses an argument called `ignored`, e.g. holding a list of things that it should ignore. (cconv--not-lexical-var-p): New function, moved from `bytecomp.el`. Don't special case keywords and `nil` and `t` since they are already `special-variable-p`. (cconv--analyze-function): Use `cconv--not-lexical-var-p`. (cconv--dynbindings): New dynbound var. (cconv-analyze-form): Use `cconv--not-lexical-var-p`. Remember in `cconv--dynbindings` the vars for which we used dynamic scoping. (cconv-analyze-form): Use `cconv--dynbound-variables` rather than `byte-compile-bound-variables`. (cconv-fv): New function. * src/eval.c (Fsetq, eval_sub): Remove optimization designed when `lexical-binding == nil` was the common case. (Ffunction): Use `internal-filter-closure-env-function` when available. (eval_sub, Ffuncall): Improve error info for `excessive_lisp_nesting`. (internal-filter-closure-env-function): New defvar.
