; Tests that the compiler dumps call site matches upon request.
|
|
;
|
|
; The test case is generated from:
|
|
;
|
|
; // main
|
|
; // |
|
|
; // f1 (noinline)
|
|
; // |
|
|
; // f2
|
|
; // |
|
|
; // f3 (noinline)
|
|
; // |
|
|
; // new
|
|
;
|
|
; __attribute__((noinline)) char *f3() { return ::new char[4]; }
|
|
;
|
|
; static char *f2() { return f3(); }
|
|
;
|
|
; __attribute__((noinline)) static char *f1() { return f2(); }
|
|
;
|
|
; int main() {
|
|
; f1();
|
|
; return 0;
|
|
; }
|
|
;
|
|
; Here we expect to match two inline call stacks:
|
|
;
|
|
; - [main]
|
|
; - [f1, f2]
|
|
;
|
|
; Note that f3 is considered to be an allocation site, not a call site, because
|
|
; it directly calls new after inlining.
