This pull request includes a few targeted changes across the codebase, primarily focusing on improving symbol locality detection in the compiler, adding a utility function for integer division and modulus, and simplifying a test case. - **Compiler Improvements** * Improved the `isLocalSym` function in `compiler/ast2nif.nim` to more accurately determine if a symbol is local by checking that the symbol's owner is not a module. - **Utility Function Addition** * Added a new `divmod` procedure in `tests/ic/tmiscs.nim` that returns both the quotient and remainder of integer division, along with a usage example. - **Test Simplification** * Simplified the `showMeters` test in `tests/ic/tconverter.nim` by removing a floating-point assertion, leaving only an output statement. ------------------------------------------------------------------------------------------------------------------ ```nim proc divmod(a, b: int): (int, int) = (a div b, a mod b) let (q, r) = divmod(17, 5) echo q echo r ``` gives `Error: unhandled exception: local symbol 'tmpTuple.0' not found in localSyms. [AssertionDefect]` `makeVarTupleSection` uses a temp of which the globalness and localness is not specified. Turning it a global variable for top level scope broke some Nim programs. So I think it's better to check the owner of the symbol ```nim if useTemp: # use same symkind for compatibility with original section let temp = newSym(symkind, getIdent(c.cache, "tmpTuple"), c.idgen, getCurrOwner(c), n.info) ```
