Fold constants
Web9 Answers Sorted by: 36 Macros are simply textual substitution, so in your example writing TIMER_100_MS in a program is a fancy way of writing 32768 / 10. Therefore, the question is when the compiler would evaluate 32768 / 10, which is a constant integral expression. WebDec 15, 2024 · Constant folding optimizer - Statically infers the value of tensors when possible by folding constant nodes in the graph and materializes the result using constants. Arithmetic optimizer - Simplifies arithmetic operations by eliminating common subexpressions and simplifying arithmetic statements.

WebConstant folding. The reason why the switch implementation is similar to a return 0 is something called constant folding. Constant folding is the process of recognizing and evaluating constant expressions at compile time rather than computing them at runtime - … WebAll C compilers can fold integer constant expressions that are present after macro expansion (ANSI C requirement). Most C compilers can fold integer constant expressions that are …

WebApr 8, 2016 · 5. In general, the C standard does not specify how something is compiled. You won't ever get a guarantee that one way to implement something is faster than another. There is no guarantee that constant folding must occur, but as the compiler must be able to evaluate constant expressions at compile time (to process #if directives and array ... WebFeb 16, 2024 · Constant expressions. A constant expression is an expression that can be evaluated by the compiler at compile-time. To be a constant expression, all the values in the expression must be known at compile-time (and all of the operators and functions called must support compile-time evaluation). When the compiler encounters a constant …
