2016年12月6日 · The epilogue and prologue of a function are simply the set of instructions that 'set up' the context for the function when it's called and clean up when it returns. The prologue typically performs such tasks as: saves any registers that the function might use (that are required by the platform's standard to be preserved across function calls)

2015年8月4日 · The prologue points ESP somewhere else, which is part of why we need an epilogue.) Then the prologue is executed: push ebp ; Save the stack-frame base pointer (of the calling function). mov ebp, esp ; Set the stack-frame base pointer to be the current ; location on the stack. sub esp, N ; Grow the stack by N bytes to reserve space for local ...

Are the prologue and epilogue mandatory when writing assembly functions? For pure assembly you don't even need to have "functions" - e.g. you can have a piece of code with multiple different entry points and a single "ret" (which is equivalent to what you might end up with after a decent compiler does "tail call" optimizations).

2014年9月29日 · I wish to create a logger class that upon the first logging.getLogger() will write a prologue and once the process ends the logger with write an epilogue my code: logger = logging.getLogger('name')

Prolog definition which detects a path. 4. transitive closure over a symmetric relation in prolog. 2.

2021年4月10日 · This is MSVC debug mode; it reserves extra space and poisons it with 0xCC (with rep stosd aka memset in a can, hence the mov rdi,rsp to set the destination) to help detect out-of-bounds access errors.

2019年5月2日 · The problem is the manual spells the words as prolog and epilog but they can also be spelled prologue and epilogue. Try querying with those alternatives and it should help. If you look at the definition of prologue. any introductory proceeding, event, etc.: or the definition of epilogue. a concluding part added to a literary work. it should ...

The solution is to put your non-top-level function invocations inside a function definition, then call that function sometime much later. The business about "if __ main __" is an idiom based on this principle, but you have to understand why, instead of simply blindly following it.

2011年12月16日 · An example is the definition of not-equals: equals(X, X). not-equals(X, Y) :- equals(X, Y), !, fail. not-equals(X, Y). not-equals(X, Y) should succeed if X is not equal to Y, and fail if it is; X and Y should be bound to ground expressions (i.e. have no free variables) when attempting to satisfy this goal.
