For tail calls, there is no need to remember the caller – instead, tail-call elimination makes only the minimum necessary changes to the stack frame before passing it on, [4] and the tail-called function will return directly to the original caller. The tail call doesn't have to appear lexically after all other statements in the source code ...
Every call in CPS is a tail call, and the continuation is explicitly passed. Using CPS without tail call optimization (TCO) will cause not only the constructed continuation to potentially grow during recursion, but also the call stack. This is usually undesirable, but has been used in interesting ways—see the Chicken Scheme compiler. As CPS ...
However, the above example unnecessarily allocates a temporary array for the result of sin(x). A more efficient implementation would allocate a single array for y, and compute y in a single loop. To optimize this, a C++ compiler would need to: Inline the sin and operator+ function calls. Fuse the loops into a single loop.
These examples reduce easily to a single recursive function by inlining the forest function in the tree function, which is commonly done in practice: directly recursive functions that operate on trees sequentially process the value of the node and recurse on the children within one function, rather than dividing these into two separate functions.
A compiler can use the results of escape analysis as a basis for optimizations: [1] Converting heap allocations to stack allocations. [2] If an object is allocated in a subroutine, and a pointer to the object never escapes, the object may be a candidate for stack allocation instead of heap allocation.
Four-time Grand Slam singles winner Naomi Osaka has started 2025 in style, beating Julia Grabher 7-5, 6-3 Wednesday to reach the quarterfinals of the Auckland tennis classic. Osaka overcame a ...
A federal judge in New York on Friday denied former New Jersey Sen. Robert Menendez's bid for a new trial. "The jury's guilty verdicts were readily supported by the extensive witness testimony and ...
For instance, inlining can cause missing stack frames, tail call optimizations can replace one stack frame with another, and frame pointer elimination can prevent call stack analysis tools from correctly interpreting the contents of the call stack. [6] For example, glibc's backtrace() function returns an output with the program function and ...
