From a8c60d7fffb6bd4f3b483369c4b8ecc4a2c83f83 Mon Sep 17 00:00:00 2001 From: "Steven G. Kargl" Date: Wed, 15 Sep 2004 14:09:17 +0000 Subject: [PATCH] check.c (gfc_check_getcwd_sub): New function. 2004-09-15 Steven G. Kargl * check.c (gfc_check_getcwd_sub): New function. * gfortran.h (GFC_ISYM_GETCWD): New symbol. * intrinsic.c (add_functions): Add function definition; Use symbol. * intrinsic.c (add_subroutines): Add subroutine definitions. * intrinsic.h: Add prototypes. * iresolve.c (gfc_resolve_getcwd, gfc_resolve_getcwd_sub): New functions. * trans-intrinsic.c (gfc_conv_intrinsic_function): Use symbol. libgfortran/ * intrinsics/getcwd.c: New file. * Makefile.am: Add getcwd.c. * Makefile.in: Regenerated.
