Examples of C and assembly languages or programming in ARM, and explanations of arm instances1. inline assembly
Notes for Embedded Assembly in C language:
You cannot assign values directly to the PC register. B or BL commands must be used for program redirection. Do not use overly complex C expressions when using physical registers, avoid physical register conflicts. R12 and R13 may be used by the compiler
", Thread_num, COUNT);}intMain () {//test1Fun1 ();//easy to find thread boot count and Count mismatch//Detecting Memory leaks_CrtDumpMemoryLeaks (); return 0;}The + + operation is divided into three layers at the assembly level: (1) The value is stored in the register, (2) in the Register, and (3) the value is dumped into memory by the register. This process is prone to problems.But using atomic operations is accurate when only 50 threads are started, but when the upper limit is tuned to 500, th

easily reuse a piece of code as you would call a function without having to pay the extra overhead of executing a function call. It is clear that the use of inline functions increases the volume of the final executable program. Saving time by changing space by time or by increasing space consumption is a common method in computer science.Attention:1 . The code in the inline function should be just a simple, fast execution of several statements. If a function is more complex, the time he execute
