--- Comment #3 from Eric Christopher <echristo at gmail.com> ---
Appears fixed:

echristo-macbookpro2:~/tmp> cat > foo.c
#include <stdint.h>
typedef unsigned uint128_t __attribute__((mode(TI)));
int main() {
  uint64_t a = ((uint64_t)2000000000) * 1000000000;
  uint64_t b = ((uint64_t)1234567890) << 24;
  uint128_t c = ((uint128_t)a) * b;
  return 0;
}
echristo-macbookpro2:~/tmp> clang foo.c
