gcc/fortran/ChangeLog: * arith.cc (gfc_arith_uminus): Fix warning. (gfc_arith_minus): Correctly truncate unsigneds. * check.cc (gfc_check_dot_product): Handle unsigned arguments. (gfc_check_matmul): Likewise. * expr.cc (gfc_get_unsigned_expr): New function. * gfortran.h (gfc_get_unsigned_expr): Add prototype. * iresolve.cc (gfc_resolve_matmul): If using UNSIGNED, use the signed integer version. * gfortran.texi: Document MATMUL and DOT_PRODUCT for unsigned. * simplify.cc (compute_dot_product): Handle unsigneds. libgfortran/ChangeLog: * m4/iparm.m4: Add UNSIGED if type is m. * m4/matmul.m4: If type is GFC_INTEGER, use GFC_UINTEGER instead. Whitespace fixes. * m4/matmul_internal.m4: Whitespace fixes. * generated/matmul_c10.c: Regenerated. * generated/matmul_c16.c: Regenerated. * generated/matmul_c17.c: Regenerated. * generated/matmul_c4.c: Regenerated. * generated/matmul_c8.c: Regeneraated. * generated/matmul_i1.c: Regenerated. * generated/matmul_i16.c: Regenerated. * generated/matmul_i2.c: Regenerated. * generated/matmul_i4.c: Regenerated. * generated/matmul_i8.c: Regenerated. * generated/matmul_r10.c: Regenerated. * generated/matmul_r16.c: Regenerated. * generated/matmul_r17.c: Regenerated. * generated/matmul_r4.c: Regenerated. * generated/matmul_r8.c: Regenerated. * libgfortran.h: Add array types for unsiged. gcc/testsuite/ChangeLog: * gfortran.dg/unsigned_25.f90: New test. * gfortran.dg/unsigned_26.f90: New test.
