--- Comment #2 from Bernd Edlinger <bernd.edlinger at hotmail dot de> ---
As of current 4.9 trunk, that may have changed a bit.
but it still does not do what one would expect:
struct s
{
int x:8;
int y:24;
};
#pragma GCC push
#pragma GCC optimize ("strict-volatile-bitfields")
int foo(volatile struct s *x)
{
return x->x;
}
#pragma GCC pop
#pragma GCC push
#pragma GCC optimize ("no-strict-volatile-bitfields")
int bar(volatile struct s *x)
{
return x->x;
}
#pragma GCC pop
Both foo and bar are compiled as if -fno-strict-volatile-bitfields
was used on gcc-invocation. Whatever pragma is used last, wins...
push/pop are ignored, and does not restore the original settings.
