From 554fd8c5195424bdbcabf5de30fdc183aba391bd Mon Sep 17 00:00:00 2001 From: upstream source tree Date: Sun, 15 Mar 2015 20:14:05 -0400 Subject: obtained gcc-4.6.4.tar.bz2 from upstream website; verified gcc-4.6.4.tar.bz2.sig; imported gcc-4.6.4 source tree from verified upstream tarball. downloading a git-generated archive based on the 'upstream' tag should provide you with a source tree that is binary identical to the one extracted from the above tarball. if you have obtained the source via the command 'git clone', however, do note that line-endings of files in your working directory might differ from line-endings of the respective files in the upstream repository. --- gcc/fortran/ChangeLog-2007 | 5776 ++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 5776 insertions(+) create mode 100644 gcc/fortran/ChangeLog-2007 (limited to 'gcc/fortran/ChangeLog-2007') diff --git a/gcc/fortran/ChangeLog-2007 b/gcc/fortran/ChangeLog-2007 new file mode 100644 index 000000000..421dc886e --- /dev/null +++ b/gcc/fortran/ChangeLog-2007 @@ -0,0 +1,5776 @@ +2007-12-31 Paul Thomas + + PR fortran/34558 + * interface.c (gfc_compare_types): Prevent linked lists from + putting this function into an endless recursive loop. + +2007-12-26 Daniel Franke + + PR fortran/34532 + * gfortran.texi: Fixed section about implicit conversion of + logical and integer variables. + +2007-12-25 Tobias Burnus + + PR fortran/34514 + * decl.c (attr_decl1): Reject specifying the DIMENSION for + already initialized variable. + (do_parm): Reject PARAMETER for already initialized variable. + +2007-12-25 Daniel Franke + + PR fortran/34533 + * intrinsic.h (gfc_check_etime): Renamed to ... + (gfc_check_dtime_etime): ... this. + (gfc_check_etime_sub): Renamed to ... + (gfc_check_dtime_etime_sub): ... this. + (gfc_resolve_dtime_sub): New prototype. + * check.c (gfc_check_etime): Renamed to ... + (gfc_check_dtime_etime): ... this. + (gfc_check_etime_sub): Renamed to ... + (gfc_check_dtime_etime_sub): ... this. + * iresolve.c (gfc_resolve_dtime_sub): New implementation. + * intrinsic.c (add_functions): Removed alias from ETIME to DTIME, + added stand-alone intrinsic DTIME. + (add_subroutines): Adjusted check and resolve function names for + DTIME and ETIME. + * trans-intrinsic.c (gfc_conv_intrinsic_function): Added DTIME + to known functions in switch. + * intrinsic.texi (DTIME): Added paragraph about thread-safety, + fixed return value section. + (CPU_TIME): Clarified intent and added implementation notes. + +2007-12-23 Tobias Burnus + + PR fortran/34421 + * resolve.c (resolve_entries): Add standard error for functions + returning characters with different length. + +2007-12-23 Daniel Franke + + PR fortran/34536 + * matchexp.c (match_ext_mult_operand): Print warning for unary + operators following arithmetic ones by default. + (match_ext_add_operand): Likewise. + +2007-12-22 Daniel Franke + + PR fortran/34559 + * simplify.c (gfc_simplify_repeat): Added safeguard for empty + string literals. + +2007-12-22 Thomas Koenig + + PR fortran/34549 + * check.c (gfc_check_cshift): Add check that shift is + type INTEGER. + +2007-12-21 Jerry DeLisle + + PR fortran/34540 + * iresolve.c (gfc_resolve_cshift): Take optional dim path + only if the argument is an optional itself. + * iresolve.c (gfc_resolve_eoshift): Same. + +2007-12-21 Paul Thomas + + PR fortran/34438 + * trans-decl.c (gfc_finish_var_decl): Do not mark derived types + with default initializers as TREE_STATIC unless they are in the + main program scope. + (gfc_get_symbol_decl): Pass derived types with a default + initializer to gfc_defer_symbol_init. + (init_default_dt): Apply default initializer to a derived type. + (init_intent_out_dt): Call init_default_dt. + (gfc_trans_deferred_vars): Ditto. + + * module.c (read_module): Check sym->module is there before + using it in a string comparison. + +2007-12-20 Tobias Burnus + + PR fortran/34482 + * gfortran.texi (BOZ): Document behavior for complex + numbers. + * target-memory.h (gfc_convert_boz): Update prototype. + * target-memory.c (gfc_convert_boz): Add error check + and convert BOZ to smallest possible bit size. + * resolve.c (resolve_ordinary_assign): Check return value. + * expr.c (gfc_check_assign): Ditto. + * simplify.c (simplify_cmplx, gfc_simplify_dble, + gfc_simplify_float, gfc_simplify_real): Ditto. + +2007-12-19 Jerry DeLisle + + PR fortran/34325 + * match.h: New function declaration. + * match.c (gfc_match_parens): New function to look for mismatched + parenthesis.
