RE: [cdt-dev] get AST nodes of a macros
|
A macro definition can be an arbitrary sequence of tokens
that does not have to satisfy any restrictions imposed
by a grammar. Therefore there is no AST for a
macro.

Subject: [cdt-dev] get AST nodes
of a macros
Importance: Low
hi all
Is it possible to get macro code converted into an
AST? or is it bound to be text?
Consider the following macro, when
creating an AST of the c code below, the macro is not converted into AST
nodes.
Only a weak structure (IASTPreprocessorMacroDefinition) containing
position where it is "called" and where to find the code for the macro is all
that is provided.
Is it possible to get the AST nodes of a macro? any
sugestions anyone? please..
#define BIARI_CTX_INIT2(ii,jj,ctx,tab,num)
\
{ \
for (i=0; i<ii; i++) \
for (j=0; j<jj; j++)
\
{ \
if
(img->type==I_SLICE) biari_init_context (&(ctx[i][j]), &(tab
## _I[num][i][j][0])); \
else
biari_init_context (&(ctx[i][j]), &(tab ## _P[num][i][j][0]));
\
} \
}
void foo() {
BIARI_CTX_INIT2 (3,
NUM_MB_TYPE_CTX, mc->mb_type_contexts,
INIT_MB_TYPE,
img->model_number);
}
