------- Additional Comments From bosch at gcc dot gnu dot org 2004-04-29 19:23 ------- Here are additional comments after reading the GCC Internals manual from the tree-ssa branch. Although Chapter 7 describes the high-level process of going from language-specific trees to GENERIC, then lowering to GIMPLE and finally going through the various SSA and non-SSA passes is described in sufficient detail, there is no information on the GENERIC and GIMPLE representations themselves.

Chapter 8 describes C and C++ front end specific trees, but there is a complete disconnect with tree- ssa. This chapter needs to be changed to reflect the situation in the tree-ssa branch.

Chapter 9, which deals with analysis and optimization of GIMPLE trees starts with a small introduction that refers to "the chapter describing GENERIC and GIMPLE" for more details. Such a chapter is much needed, especially since one of the stated goals of tree-ssa is to improve maintainability.
