Hello all,
Suppose that I have some header file in C myhead.h, containing notably
// Boehm's garbage collector, notably defines GC_malloc_atomic & GC_malloc
#include <gc/gc.h>
struct myintvec_st {
unsigned vsiz; // allocated size
unsigned vlen; // used length, always <= vsiz
int varr[];
};
static inline struct myintvec_st*vec_alloc(unsigned siz) {
size_t fullsiz = sizeof(struct myintvec_st)+siz*sizeof(int));
struct myintvec_st* v = GC_malloc_atomic(fullsiz);
memset(v, 0, fullsiz);
v->vsiz = siz;
return v;
}
and many other struct declaration and static inline functions and extern
function declarations.
Now, I would like to use libgccjit with a context which contains all
the functions & structures from file myhead.h, in particular because I
want to JIT some calls to inlined static functions, and I expect the
gccjit to do the inlining (assuming I am using JIT with -O2 by calling
gcc_jit_context_set_int_option with
GCC_JIT_INT_OPTION_OPTIMIZATION_LEVEL to 2).
How is that possible? What should be done to make that possible?
I imagine that we might need a new function which initialize a
gcc_jit_context from a precompiled header...
Where should it go?
Regards.
