Hi all i came across Sparse a few months ago and looks really interesting. Now, I have a few questions regarding the sparse infrastructure: 1) Regarding the intermediate representation dumps that can be generated (via "test-linearize" i think). Do you support canonical SSA form (as defined in the classical books/papers)? 2) Is it possible to generate a self-contained IR dump, so that it could be possible to feed it to external (third-party) code selectors? In my mind a single C program file (actually read: translation unit) would be translated to something like the following structure: struct CTranslationUnit { struct GlobalVars; // is a List of global variables (scalars, arrays etc) struct ProcedureList; } struct ProcedureList { struct LocalVars; // local variable list List ThreeAddressCodeInstr; // three-address code operations (4-tuples) } There a couple of frontends that can do this (the proprietary/no cost for research only LANCE compiler frontend). 3) What does the c2xml backend exactly do? 4) Is there anyone working on a RISC-like processor backend project. I feel that if the entire backend can be contained in something like "compile-i386.c" then it could be even possible to automate the generation of such file from a more compact specification file. (plus some hand-written intrinsics probably). 5) Is there any documentation covering the API and linked tools to the sparse library (something more than the man pages)? 6) Sparse looks good. I like the IR dumps a lot.
