bug#63957: 29.0.91; c-ts-mode: incorrect fontification in alloc.c |

To reproduce:
emacs -Q
C-x C-f src/alloc.c RET
M-x c-ts-mode RET
C-u 3184 M-g g
Observe that several "else if" clauses in the following fragment are not
fontified correctly:
#ifdef HAVE_TREE_SITTER
else if (PSEUDOVECTOR_TYPEP (&vector->header, PVEC_TS_PARSER))
treesit_delete_parser (PSEUDOVEC_STRUCT (vector, Lisp_TS_Parser));
else if (PSEUDOVECTOR_TYPEP (&vector->header, PVEC_TS_COMPILED_QUERY))
treesit_delete_query (PSEUDOVEC_STRUCT (vector, Lisp_TS_Query));
#endif
#ifdef HAVE_MODULES
else if (PSEUDOVECTOR_TYPEP (&vector->header, PVEC_MODULE_FUNCTION))
{
ATTRIBUTE_MAY_ALIAS struct Lisp_Module_Function *function
= (struct Lisp_Module_Function *) vector;
module_finalize_function (function);
}
#endif
#ifdef HAVE_NATIVE_COMP
else if (PSEUDOVECTOR_TYPEP (&vector->header, PVEC_NATIVE_COMP_UNIT))
{
struct Lisp_Native_Comp_Unit *cu =
PSEUDOVEC_STRUCT (vector, Lisp_Native_Comp_Unit);
unload_comp_unit (cu);
}
else if (PSEUDOVECTOR_TYPEP (&vector->header, PVEC_SUBR))
{
struct Lisp_Subr *subr =
PSEUDOVEC_STRUCT (vector, Lisp_Subr);
if (!NILP (subr->native_comp_u))
{
/* FIXME Alternative and non invasive solution to this
cast? */
xfree ((char *)subr->symbol_name);
xfree (subr->native_c_name);
}
}
#endif
In this fragment, "else" has the font-lock-type-face, and "if" has the
font-lock-function-name-face.
I'm guessing this is caused by the #ifdef's there, but can this be
fixed, please?
FTR, I'm using the latest tree-sitter-c grammar library, built from
the HEAD of their Git repository.
