inline function in different translation units with different compiler flags undefined behaviour?

问题 in visual studio you can set different compiler options for individual cpp files. for example: under "code generation" we can enable basic runtime checks in debug mode. or we can change the floating point model (precise/strict/fast). these are just examples. there are plenty of different flags. an inline function can be defined multiple times in the program, as long as the definitions are identical. we put this function into a header and include it in several translation units. now, what

Are nested functions possible in VBA?

I'm trying to clean up code by stripping parameters from a function within a private scope, like this: Function complicatedFunction(x as Double, param1 as Double, param2 as Double) ... End Function Function mainActionHappensHere(L as Double, U as Double ...) Function cleaner(x) cleaner = complicatedFunction(x, L, U) End Function ... cleaner(x) 'Many calls to this function ... End Function Is this possible? Compiler complains, "Expected End Function", since I'm beginning a function before ending the outer one. And Google is no help :( PS I can't define cleaner() outside of mainActionHappensHere

Inlining C++ code

问题 Is there any difference to the following code: class Foo { inline int SomeFunc() { return 42; } int AnotherFunc() { return 42; } }; Will both functions gets inlined? Does inline actually make any difference? Are there any rules on when you should or shouldn't inline code? I often use the AnotherFunc syntax (accessors for example) but I rarely specify inline directly. 回答1: Both forms should be inlined in the exact same way. Inline is implicit for function bodies defined in a class definition.

Is there any good way for an inline function to access private or internal values?

问题 I just ran into an issue: when I try to access a private or internal value from an inline function, I get the error "The value 'xxx' was marked inline but its implementation makes use of an internal or private function which is not sufficiently accessible". While logical, I wonder if anyone has a good work around. The best thing I can think to do is place the values publicly in a nested module and just hope no-one goes poking around (which I'm not too worried about anyway, since these values

Inlining of vararg functions

While playing about with optimisation settings, I noticed an interesting phenomenon: functions taking a variable number of arguments ( ... ) never seemed to get inlined. (Obviously this behavior is compiler-specific, but I've tested on a couple of different systems.) For example, compiling the following small programm: #include <stdarg.h> #include <stdio.h> static inline void test(const char *format, ...) { va_list ap; va_start(ap, format); vprintf(format, ap); va_end(ap); } int main() { test("Hello %s\n", "world"); return 0; } will seemingly always result in a (possibly mangled) test symbol

Tool to automatically inline JavaScript function calls?

Inlining JavaScript function calls speeds up the execution and also reduces the code size after gzipping, as described in this article: http://blog.calyptus.eu/seb/2011/01/javascript-call-performance-just-inline-it/ However, I can't find a tool which automatically processes a JS source file and inlines all (or better, selected) inlinable function calls in it. Google's Closure Compiler does some inlining, but not always, and nor is it configurable. Thanks in advance! Let the JIT figure things like inlining out fr you. Inlining can easily worsen the performance by killing cache performance. Also
