1. __attribute__ One of the major features of GNU C (which is not known to beginners) is the __attribute__ mechanism. __ATTRIBUTE__ can set function attributes, variable attributes (Variable attribute), and type attributes There are two underscores before and after the __attribute__, followed by a pair of original brackets, with the corresponding __attribute__ parameters inside the brackets. The __ATTRIBUTE__ syntax format is: __attribute__ ((att

The basic file formats of the arm system are commonly used in ARM-based embedded system development.There are three basic file formats for the arm system:1) bin, flat-board binary format, which is generally used for Directly Writing to flash and loading to the monitor program.2) Elf, executable and linkable format, a common object file format, generally generated by GNU Compiler Collection (GCC.3) axf, an extended version in Bin format. The main part

GPROF Introduction GPROF is the GNU profiler tool. It can display the "flat profile" of the program running, including the number of calls to each function and the processor time consumed by each function. You can also display the "Call diagram", including the call relationship of the function, and the time consumed by each function call. You can also display the "annotated source code", which is a copy of the program source code, marking the number o

I used GCJ to compile itext and used itext to write many small programs (pdfrotate and nup_pdf can be obtained from the Internet now). Here I will only introduce how to obtain the GCJ compiling environment. GCJ is a Java editor based on the GNU protocol. It supports the following compilation methods:Java Source Code directly compiles the local machine code. On windows, the exe executable program (separated from JRE) is used );Java source code is comp
