I suspect this is not currently visible to any in-tree code. Perhaps
we could teach -ast-dump to dump this flag, and test it that way.
It seems that -ast-print is able to show the difference ... but I can
not tell if this is only happening by chance (the status of the pretty
printer is unclear to me):
$ cat a.cc
float test() {
return __builtin_asinf(1.0);
}
Before the patch we were getting:
$ clang++ -cc1 -ast-print a.cc
float test() {
return __builtin_asinf(1.);
}
extern "C" extern float __builtin_asinf(float) __attribute__((nothrow))
__attribute__((const))
$
After the patch, only function test() is printed out.
Enea.
