Parameter transfer during function call in ARM system

In embedded software programming, function calls are often used. When I learned how to embed assembly in C language, I learned that the parameter call before C language is to use registers R0 to pass the first parameter, r1 passed to second .. until R3 passes the fourth parameter. but in fact, sometimes there may be a lot of parameters passed, more than 8, or there are floating point and so on in the parameter, the parameter will also exceed 4 registers, for the excess part does not use

Requirejs Introductory Learning Chapter

REQUIREJS provides a packaged compression tool r.js to merge and compress the modules. R.js is very powerful, not only can compress js,css, can even package the whole project. The R.js compression tool uses UGLIFYJS or closure Compiler. Default uses Uglifyjs (jquery also uses it to compress). In addition R.js needs to node.js environment, of course it can also run in the Java environment such as Rhino. This article takes a simple example to feel the R.js, the directory created below Like
