Programming Efficiently with the NVIDIA CUDA 11.3 Compiler …
The alloca built-in function that can be used to allocate dynamic memory out of the stack frame is now available for use in device code as a preview feature. With the CUDA 11.3 release, the CUDA C++ language is extended to enable the use of the constexpr and auto keywords in broader contexts. The CUDA device linker has also been extended with ...
Other Builtins (Using the GNU Compiler Collection (GCC))
Since the __builtin_alloca function doesn't validate its argument it is the responsibility of its caller to make sure the argument doesn't cause it to exceed the stack size limit. The __builtin_alloca function is provided to make it possible to allocate on the stack arrays of bytes with an upper bound that may be computed at run time. Since C99 Variable Length …
The perils of alloca function
The difference between alloca and malloc is that memory is allocated on the stack instead of heap. The stack memory is automatically freed when you leave the function. Stack allocation is much faster: your program just decrements the stack pointer and probes the allocated memory. The program stack is reused for other functions, so it's often ...

If size is greater than _ALLOCA_S_THRESHOLD, then _malloca attempts to allocate on the heap, and returns a null pointer if the space can't be allocated. If size is less than or equal to _ALLOCA_S_THRESHOLD, then _malloca attempts to allocate on the stack, and a stack overflow exception is generated if the space can't be allocated. The …

The function alloca () is used to allocate memory for a stack frame. It's just an unconventional method of dynamically allocating memory. When a function returns its …
LLVM Language Reference Manual — LLVM 18.0.0git …
The alloca, or argument allocation, must also be tagged with the inalloca keyword. Only the last argument may have the inalloca attribute, and that argument is guaranteed to be passed in memory. An argument allocation may be used by a call at most once because the call may deallocate it.

alloca.h
Avr-libc defines the alloca() as a macro, which is translated into the inlined c __builtin_alloca() function. The fact that the code is inlined, means that it is impossible to take the address of this function, or to change its behaviour by linking with a different library. return alloca() returns a pointer to the beginning of the allocated space

x64 stack usage | Microsoft Learn
A function that does not require a stack frame is called a leaf function. A frame function is a function that allocates stack space, calls other functions, saves nonvolatile registers, or uses exception handling. It also requires a function table entry. A frame function requires a prolog and an epilog. A frame function can dynamically allocate ...
