re PR fortran/25031 ([4.1 only] Allocatable array can be reallocated.)
2006-03-03 Thomas Koenig <Thomas.Koenig@online.de> PR fortran/25031 * trans-array.h: Adjust gfc_array_allocate prototype. * trans-array.c (gfc_array_allocate): Change type of gfc_array_allocatate to bool. Function returns true if it operates on an array. Change second argument to gfc_expr. Find last reference in chain. If the function operates on an allocatable array, emit call to allocate_array() or allocate64_array(). * trans-stmt.c (gfc_trans_allocate): Code to follow to last reference has been moved to gfc_array_allocate. * trans.h: Add declaration for gfor_fndecl_allocate_array and gfor_fndecl_allocate64_array. (gfc_build_builtin_function_decls): Add gfor_fndecl_allocate_array and gfor_fndecl_allocate64_array. 2006-03-03 Thomas Koenig <Thomas.Koenig@online.de> PR fortran/25031 * runtime/memory.c: Adjust copyright years. (allocate_array): New function. (allocate64_array): New function. * libgfortran.h (error_codes): Add ERROR_ALLOCATION. 2006-03-03 Thomas Koenig <Thomas.Koenig@online.de> PR fortran/25031 * multiple_allocation_1.f90: New test.
