Fix mode mismatch in expand_parity

expand_parity attempts to generate popcount operations in wider modes and do a logical AND afterward, but it overlooks the mode of "target" and just do: if (temp != 0) temp = expand_binop (wider_mode, and_optab, temp, const1_rtx,

[Patch, fortran] Implement inquire(iolength= ) for DTIO

This very simple patch implements the subject feature. Fortran Standard draft F2016 states in 9.10.3.2: The output list in an INQUIRE statement shall not contain any derived-type list items that require a defined input/output procedure as described in subclause 9.6.3. If a derived-type list it

Hi Richard, This patch makes a minor change to genmatch to add reverse keyword for iterating over user-defined operators in reverse in for-stmt and in define_operator_list. eg: (for op (bit_and bit_ior) rop (reverse (op)) ...) Verified gimple-match.c and generic-match.c remain unchanged wi

C++ PATCH for c++/77945 (constexpr copy and tail padding)

For classes with trivial copy constructors that might have other data packed into their tail padding, we represent the copy with an assignment between arrays of unsigned char. This is valid in normal code, but constant expressions don't allow that sort of type punning, so we need to look through i
