This is basically documentation of AVR specific extensions and stuff like * command line options like -maccumulate-args etc. * AVR named address spaces
Section doc/extend.texi::Named Address Spaces is split into several subsections now; each subsection taking care of one target in alphabetical order: AVR, M32C, RL78, SPU. As I already wrote in http://gcc.gnu.org/ml/gcc/2012-01/msg00175.html references in the documentation miss their intended anchors/targets. That is a general problem and not specific to the new references introduced by this patch. Ok to commit? Johann * doc/extend.texi (Named Address Spaces): Split into subsections. (AVR Named Address Spaces): New subsection. (M32C Named Address Spaces): New subsection. (RL78 Named Address Spaces): New subsection. (SPU Named Address Spaces): New subsection. (Variable Attributes): New anchor "AVR Variable Attributes". (AVR Variable Attributes): Rewrite and avoid wording "address space" in this context. * doc/invoke.texi (AVR Options): Rewrite and add documentation for -maccumulate-args, -mbranch-cost=, -mrelax, -mshort-calls. (AVR Built-in Macros): New subsubsection therein. * doc/md.texi (AVR constraints): Remove "C04", "R".
