* Makefile.am: Add generated files for large real and integers
kinds. Add a rule to create the kinds.inc c99_protos.inc files.
Use kinds.inc to preprocess Fortran generated files.
* libgfortran.h: Add macro definitions for GFC_INTEGER_16_HUGE,
GFC_REAL_10_HUGE and GFC_REAL_16_HUGE. Add types gfc_array_i16,
gfc_array_r10, gfc_array_r16, gfc_array_c10, gfc_array_c16,
gfc_array_l16.
* mk-kinds-h.sh: Define macros HAVE_GFC_LOGICAL_* and
HAVE_GFC_COMPLEX_* when these types are available.
* intrinsics/ishftc.c (ishftc16): New function for GFC_INTEGER_16.
* m4/all.m4, m4/any.m4, m4/count.m4, m4/cshift1.m4, m4/dotprod.m4,
m4/dotprodc.m4, m4/dotprodl.m4, m4/eoshift1.m4, m4/eoshift3.m4,
m4/exponent.m4, m4/fraction.m4, m4/in_pack.m4, m4/in_unpack.m4,
m4/matmul.m4, m4/matmull.m4, m4/maxloc0.m4, m4/maxloc1.m4,
m4/maxval.m4, m4/minloc0.m4, m4/minloc1.m4, m4/minval.m4, m4/mtype.m4,
m4/nearest.m4, m4/pow.m4, m4/product.m4, m4/reshape.m4,
m4/set_exponent.m4, m4/shape.m4, m4/specific.m4, m4/specific2.m4,
m4/sum.m4, m4/transpose.m4: Protect generated functions with
appropriate "#if defined (HAVE_GFC_type_kind)" preprocessor directives.
* Makefile.in: Regenerate.
* all files in generated/: Regenerate.
* f95-lang.c (DO_DEFINE_MATH_BUILTIN): Add support for long
double builtin function.
(gfc_init_builtin_functions): Add mfunc_longdouble,
mfunc_clongdouble and func_clongdouble_longdouble trees. Build
them for round, trunc, cabs, copysign and pow functions.
* iresolve.c (gfc_resolve_reshape, gfc_resolve_transpose): Add
case for kind 10 and 16.
* trans-decl.c: Add trees for cpowl10, cpowl16, ishftc16,
exponent10 and exponent16.
(gfc_build_intrinsic_function_decls): Build nodes for int16,
real10, real16, complex10 and complex16 types. Build all possible
combinations for function _gfortran_pow_?n_?n. Build function
calls cpowl10, cpowl16, ishftc16, exponent10 and exponent16.
* trans-expr.c (gfc_conv_power_op): Add case for integer(16),
real(10) and real(16).
* trans-intrinsic.c: Add suppport for long double builtin
functions in BUILT_IN_FUNCTION, LIBM_FUNCTION and LIBF_FUNCTION
macros.
(gfc_conv_intrinsic_aint): Add case for integer(16), real(10) and
real(16) kinds.
(gfc_build_intrinsic_lib_fndecls): Add support for real10_decl
and real16_decl in library functions.
(gfc_get_intrinsic_lib_fndecl): Add cases for real and complex
kinds 10 and 16.
(gfc_conv_intrinsic_exponent): Add cases for real(10) and real(16)
kinds.
(gfc_conv_intrinsic_sign): Likewise.
(gfc_conv_intrinsic_ishftc): Add case for integer(16) kind.
* trans-types.c (gfc_get_int_type, gfc_get_real_type,
gfc_get_complex_type, gfc_get_logical_type): Doesn't error out in
the case of kinds not available.
* trans.h: Declare trees for cpowl10, cpowl16, ishftc16,
exponent10 and exponent16.
* gfortran.dg/large_real_kind_2.F90: New test.
* gfortran.dg/large_integer_kind_2.f90: New test.
