1 dnl Support macro file for intrinsic functions.
2 dnl Contains the generic sections of the array functions.
3 dnl This file is part of the GNU Fortran Runtime Library (libgfortran)
4 dnl Distributed under the GNU GPL with exception. See COPYING for details.
6 dnl Pass the implementation for a single section as the parameter to
7 dnl {MASK_}ARRAY_FUNCTION.
8 dnl The variables base, delta, and len describe the input section.
9 dnl For masked section the mask is described by mbase and mdelta.
10 dnl These should not be modified. The result should be stored in *dest.
11 dnl The names count, extent, sstride, dstride, base, dest, rank, dim
12 dnl retarray, array, pdim and mstride should not be used.
13 dnl The variable n is declared as index_type and may be used.
14 dnl Other variable declarations may be placed at the start of the code,
15 dnl The types of the array parameter and the return value are
16 dnl atype_name and rtype_name respectively.
17 dnl Execution should be allowed to continue to the end of the block.
18 dnl You should not return or break from the inner loop of the implementation.
19 dnl Care should also be taken to avoid using the names defined in iparm.m4
