. It looks like the first book that covers IR completely. Unfortunately, IR has progressed rapidly over the years, and the book is somewhat outdated. It's a good idea to turn over and do a reference. In addition, Ricardo is now the head of Yahoo! for Europe and Latin Ameria."Pattern Classification (2ed)", Richard O. Duda, Peter E. Hart, David G.

machine code. The practice is to compile to C + +, and then use the ordinary C + + compiler to eventually compile to machine code. This is actually to take C + + as the compiler's IR (intermediate representation, middle) to use, because already have a ready-made C + + compiler can be compiled C + + source code to the machine, equal to the compiler backend (IR-machine code) can be saved , just write a compi

For example: # DEFINE _ slow_down_io _ ASM _ volatile _ ("outb % Al, $0x80 ") This is an 8-bit output command. As mentioned above, adding the suffix "B" to the operator indicates that this is 8-bit, while 0x80 is a constant, that is, the so-call
