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. That's a comment ^_^
Kind regards,
Nikolaos Kavvadias
