Not currently.
Dan was saying something like a C interface to IMCC which bypasses the parser and lexer phases was possible ?
Yes. But there is nothing defined now.
The 2 basic structures of a parsed code stream in imcc are:
- struct _Instruction
- struct SymReg
along with some flags.
And there is (almost) only one function iANY() which takes a **SymReg and an opcode to generate the instruction stream. So it probably wouldn't be to hard to build the interface here.
The problem grows as the number of languages supported increases ...
Yes, but I think, that incompatible changes shouldn't be necessary any more - sorry for breaking things.
I really would like something like this (shameless snitch) IMCC_Var *tempVar ; IMCC_Expr *expr; tempVar = IMCC_GenTempVar(code,type);
SymReg *r = mk_ident(char *name, char type)
expr = IMCC_GenAdd(code,myParam1,myParam2);
iANY("add", R3(r0,r1,r2))
IMCC_GenAssign(code,tempVar,expr);
iANY("set", R2(r, r0))
IMCC_GenIf(code,tempVar,thenStmt);
iANY("if", R2(r, thenr))
IMCC_ReleaseTempVar(code,tempVar);
namespace patch
IMCC_GenCode(code,fp);
above iANY()s append the generated instructions to the double linked instruction list.
