inline

问题 Is there a way to obtain a list of functions that were NOT inlined anywhere? Either by passing an option to gcc or by inspecting the binary? EDIT: I know how to explicitly ask for a function not to be inlined by using gcc's builtin attribute noinline. 回答1: Use gcc's -fdump-tree-all and search the dump files for "inline". 回答2: Add -fdump-ipa-inline to your compiler options. Grep the file yoursourcefile.inline which is created next to the object file for "Considering inline candidate" to find

问题 (EDIT: Let's title this, "Lessons in how measurements can go wrong." I still haven't figured out exactly what's causing the discrepancy though.) I found a very fast integer square root function here by Mark Crowne. At least with GCC on my machine, it's clearly the fastest integer square root function I've tested (including the functions in Hacker's Delight, this page, and floor(sqrt()) from the standard library). After cleaning up the formatting a bit, renaming a variable, and using fixed

问题 I have a little issue with React. I can't create a nested component with a for loop. What I want to do is create 9 cells of a table and then create 3 rows with 3 cells for every row and after that mount the 3 rows together and create a board 9x9. Let say that I want to get something like this, but using a loop class Board extends React.Component { renderSquare(i) { return <Square value={this.props.squares[i]} onClick={() => this.props.onClick(i)} />; } render(){ return( <div> <div className=

问题 Is one of these faster? inline int ProcessByValue(int i) { // process i somehow } inline int ProcessByReference(const int& i) { // process i somehow } I know that integral types should be passed by value. However, I am concerned that the compiler might inline ProcessByValue to contain a copy. Is there a rule for this? 回答1: The parameter should be typed according to what makes sense for the function. If the function takes a primitive type, pass by value would make sense. Some people I know

问题 Simple question : how can I make the inline CKEditor toolbar float top right (or bottom right) of my editable element instead of the default top left position ? Have been googling it but no luck so far :( Thank you 回答1: It does not have a configuration option for this. There are only four options for the X,Y offset in pinned and docked modes - e.g. config.floatSpacePinnedOffsetY. The only idea that I have is implementing your own plugin like Floating Space, or modifying the current

问题 I'm trying to get the inline package working on my macbook. The following block of code (from the cxxfunction examples) fails: library(inline) fx <- cxxfunction( signature(x = "integer", y = "numeric" ) , ' return ScalarReal( INTEGER(x)[0] * REAL(y)[0] ) ; ' ) fx( 2L, 5 ) With this error: Error in compileCode(f, code, language = language, verbose = verbose) : Compilation ERROR, function(s)/method(s) not created! make: g++-4.2: No such file or directory make: *** [file141b5882.o] Error 1 This

问题 In C++17 we got inline variables and I have assumed that global constexpr variables are implicitly inline. But apparently this is true only for static member variables. What is the logic/technical limitation behind this? source: A static member variable (but not a namespace-scope variable) declared constexpr is implicitly an inline variable. 回答1: The point here is that constexpr int x = 1; at namespace scope has internal linkage in C++14. If you make it implicitly inline without changing the

问题 What are the right sizes for a webpage to be printed on A4 size paper? What other stuff should be considered? *inline CSS is preferred in this case Clarification: This web-page's only propose is to be printed, since it is a receipt. Clarification # 2: This web-page is for the internal use of the company I'm working for. They would like it to look professionally designed receipt. Clarification # 3: This web-page must be printed on one page -of A4 size- only. 回答1: Answer I'd recommend using two

问题 I am doing an online bytecode method inlining optimization using ASM. My changes are based on the example 3.2.6 Inline Method (http://asm.ow2.org/current/asm-transformations.pdf). The test example (inline callee's calculate(int,int) at Caller::test) is: public class Caller { final Callee _callee; public Caller(Callee callee){ _callee = callee; } public static void main(String[] args) { new Caller(new Callee("xu", "shijie")).test(5, 100); } public void test(int a, int b){ int t = a; int p = b;
