I have read http://gcc.gnu.org/onlinedocs/gccint/RTL.html document and I have got compiler information applying -fdump-rtl-all option. My main doubt is how RTL is defined, this is, what it represents. I suppose is something very close to assembler, because It has to represent the operations between registers. But I don't know how RTL is defined from IR. At the end, RTL represents a low-level intermediate representation (language) that its internally represented by a tree, but I find no place where is defined what can representate a RTL tree node, etc. Thanks Fran
