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. | |
5 | dnl | |
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 | |
