Hello,
During the development of a patch I encountered some strange behavior
and decided to investigate. The result of which is I think I found a bug
with 'wide_int_storage::set_len' in gcc/wide-int.h.
The function reads:
inline void
wide_int_storage::set_len (unsigned int l, bool is_sign_extende
Hello,
During the development of a patch I encountered some strange behavior
and decided to investigate. The result of which is I think I found a bug
with 'wide_int_storage::set_len' in gcc/wide-int.h.
The function reads:
inline void
wide_int_storage::set_len (unsigned int l, bool is_sign_extende
