alter deprecation tests to eliminate duplicate warnings.
There are actually several constructs that have duplicated warnings.
The code below gives duplicates for each of the dg-warning cases shown:
I have not succeeded in getting the testsuite to recognize the duplicates (see
PR30612), even when putting a single case in one testfile as per the workaround
in the PR.
So, at present, one has to look at g++.log to confirm that the problems are
resolved.
===
gcc/cp/ChangeLog:
gcc/cp/typeck.c(build_class_member_access_expr): Don't check for deprecation
here.
gcc/cp/call.c(build_call_a): Ditto.
(build_over_call): Ditto.
(convert_like_real): Check for deprecation here instead.
(build_new_method_call): Ditto.
===
void func(void) __attribute__((deprecated));
void f(void) {
func(); // { dg-warning "'void func\\(\\)' is deprecated" "func()" }
}
struct s1 {
int notdep ;
int depfield __attribute__((deprecated));
union {
int notdep;
int deprec __attribute__((deprecated));
} u1 ;
union {
int notdep1;
int notdep2;
} u2 __attribute__((deprecated)) ;
} ;
int main(void) {
struct s1 a;
int b;
b = a.notdep;
b += a.depfield; // { dg-warning "'s1::depfield' is deprecated .declared at"
"depfield" }
b += a.u1.notdep;
b += a.u1.deprec; // { dg-warning "'s1::<anonymous union>::deprec' is
deprecated .declared at" "s1::u1.deprec" }
b += a.u2.notdep1 ;// { dg-warning "'s1::u2' is deprecated .declared at"
"s1::u2" }
return 0;
}
