--- Comment #4 from gprocida at google dot com ---
And, for completeness, and example where the ABI has changed incompatibly b=
ut
the ABI XML remains the same.

=3D=3D> test2.0.c <=3D=3D
#include <inttypes.h>

struct S {
  char name[5];
  uint8_t bit:1;
  uint32_t :0;
};

uint8_t foo(const struct S * s) { return s->bit; }

=3D=3D> test2.1.c <=3D=3D
#include <inttypes.h>

struct S {
  char name[5];
  uint16_t :0;
  uint8_t bit:1;
  uint32_t :0;
};

uint8_t foo(const struct S * s) { return s->bit; }
