(value_assign): Check if lval_computed write method is NULL. * value.h (struct lval_funcs): Comment NULL values for read and write methods. --- gdb/valops.c | 11 ++++++++--- 1 file changed, 8 insertions(+), 3 deletions(-) (limited to 'gdb/valops.c') diff --git a/gdb/valops.c b/gdb/valops.c index 32d71cd..e88e9dc 100644 --- a/gdb/valops.c +++ b/gdb/valops.c @@ -1110,7 +1110,8 @@ value_fetch_lazy (struct value *val) watchpoints from trying to watch the saved frame pointer. */ value_free_to_mark (mark); } - else if (VALUE_LVAL (val) == lval_computed) + else if (VALUE_LVAL (val) == lval_computed + && value_computed_funcs (val)->read != NULL) value_computed_funcs (val)->read (val); else if (value_optimized_out (val)) /* Keep it optimized out. */; @@ -1381,9 +1382,13 @@ value_assign (struct value *toval, struct value *fromval) { const struct lval_funcs *funcs = value_computed_funcs (toval); - funcs->write (toval, fromval); + if (funcs->write != NULL) + { + funcs->write (toval, fromval); + break; + } } - break; + /* Fall through. */ default: error (_("Left operand of assignment is not an lvalue.")); -- cgit v1.1
