re PR fortran/31201 (Too large unit number generates wrong code)
2007-05-06 Jerry DeLisle <jvdelisle@gcc.gnu.org>
Francois-Xavier Coudert <fxcoudert@gcc.gnu.org>
PR fortran/31201
* gfortran.h: Add runtime error codes from libgfortran.h. Define
MAX_UNIT_NUMBER.
* trans.c (gfc_trans_runtime_check): Update the format of runtime error
messages to match library runtime errors. Use call to new library
function runtime_error_at().
* trans.h: Add prototype for new function gfc_trans_io_runtime_check.
Add declaration for library functions runtime_error_at and
generate_error.
* trans_io.c (gfc_trans_io_runtime_check): New function.
(set_parameter_value): Add error checking for UNIT numbers.
(set_parameter_ref): Initialize the users variable to zero.
(gfc_trans_open): Move setting of unit number to after setting of common
flags so that runtime error trapping can be detected.
(gfc_trans_close): Likewise. (build_filepos): Likewise.
(gfc_trans_inquire): Likewise. (build_dt): Likewise.
* trans-decl.c: Add declarations for runtime_error_at and
generate_error. (gfc_build_builtin_function_decls): Build function
declarations for runtime_error_at and generate_error.
