GNU Global is a more user-friendly tag system, but because it supports too few languages, it is now generally used as the front end, with the latest universal Ctags in the back end.The Compile method is as follows:1. Go to GNU Project https://www.gnu.org/software/global/download.html Download source code2. Switch to the source directory executionsh reconf.sh3../configure--with-exuberant-ctags=/usr/local/bin

As an efficient and tightly integrated hardware platform, assembly language plays an important role in the operating system, embedded development and other fields. Because the assembler relies on the hardware structure (CPU script), the assembly language of the different architectures is also very divergent. This article briefly introduces the ATAMP;T syntax under Linux (the GNU as Assembly Syntax) and the basic methods of compiling it under Linux.
