	* com.c (ffecom_expr_power_integer_): Push temp vars
	before expanding a statement expression, since that seems
	to cause temp vars to be "forgotten" after the end of the
	expansion in the back end.  Disallow more temp-var
	pushing during such an expansion, just in case.
	(ffecom_push_tempvar): Crash if a new variable needs to be
	pushed but cannot be at this point (should never happen).

Wed May 17 12:26:16 1995  Craig Burley  (burley@gnu.ai.mit.edu)

	* expr.c (ffeexpr_collapse_convert): Add code to convert

	New function.

Sun May 14 00:00:09 1995  Craig Burley  (burley@gnu.ai.mit.edu)

	ffecom_start_progunit_, ffecom_sym_transform_,
	ffecom_init_0, start_function): Changes to have REAL
	external functions return same type as DOUBLE PRECISION
	external functions when -ff2c is in force; while at it,
	some code cleanups done.

	* stc.c (ffestc_R547_item_object): Disallow array declarator
	if one already exists for symbol.

	* ste.c (ffeste_R1227): Convert result variable to type
	of function result as seen by back end (e.g. for when REAL
	external function actually returns result as double).

	* target.h (FFETARGET_defaultFIXED_LINE_LENGTH): New
	macro for default for -ffixed-line-length-N option.

	* top.c (ffe_fixed_line_length_): Initialize this to new

	* lex.c (ffelex_send_token_): If sending CHARACTER token with
	null text field, put a single '\0' in it and set length/size
	fields to 0 (to fix 950508-0.f).
	(ffelex_image_char_): When setting ffelex_bad_line_ to TRUE,
	always "close" card image by appending a null char and setting
	ffelex_card_length_.  As part of this, append useful text
	to identify the two kinds of problems that involve this.
	(ffelex_file_fixed): Reset ffelex_bad_line_ to FALSE after
	seeing a line with invalid first character (fixes 950508-1.f).
	If final nontab column is zero, assume tab seen in line.

	longer than reflected by ffelex_card_size_.
	(ffelex_init_1): Get final nontab column info from top instead
	of assuming 72.

	* options-lang.h: Add -ffixed-line-length- prefix.

	* top.h: Add ffe_fixed_line_length() and _set_ version, plus
	corresponding extern.

	* top.c: Handle -ffixed-line-length- option prefix.

	to close include file, for its tracking needs for -I,
	instead of using fclose.

	* options-lang.h: Add -I prefix.

	* parse.c (yyparse): Call ffecom_file for main input file,
	so -I handling works (diagnostics).

	* std.c (ffestd_S3P4): Have ffecom_open_include handle
	opening and diagnosing errors with INCLUDE files.

	* ste.c (ffeste_begin_iterdo_): Use correct algorithm for
	calculating # of iterations -- mathematically similar but
	computationally different algorithm was not handling cases
	like "DO I=6,5,2" correctly, because (5-6)/2+1 => 1, not 0.

	* top.c (ffe_decode_option): Allow -I, restructure a bit
	for clarity and, maybe, speed.

Mon Apr 17 13:31:11 1995  Craig Burley  (burley@gnu.ai.mit.edu)

Sun Apr 16 00:22:48 1995  Craig Burley  (burley@gnu.ai.mit.edu)

	* Make-lang.in (F77_SRCS): Remove g77.c, since it doesn't
	contribute to building f771.

	* Makefile.in (dircheck): Remove/replace with f/Makefile, because
	phony targets that are referenced in other real targets get run
	when those targets are specified, which is a waste of time (e.g.
	when rebuilding and only g77.c has changed, f771 was being linked
	anyway).

	* g77.c: Include -lc between -lf2c and -lm throughout.

	* implic.c (ffeimplic_establish_symbol): If -Wimplicit, warn if
	implicit type given to symbol.

	type to keep DCMPLX(I) from crashing the compiler.
	(ffecom_expr_): Don't convert result from ffecom_tree_divide_.
	(ffecom_tree_divide_): Add tree_type argument, have all callers
	pass one, and don't convert right-hand operand to it (this is
	to make this new function work as much like the old in-line
	code used in ffecom_expr_ as possible).

	* lex.c: Maintain lineno and input_filename the way the gcc
	lexer does.

	* std.c (ffestd_exec_end): Save and restore lineno and
	input_filename around the second pass, which sets them
	appropriately for each saved statement.

	(ffecom_tree_divide_): New function.

Wed Apr  5 14:15:44 1995  Craig Burley  (burley@gnu.ai.mit.edu)

	* lex.c: Change to allocate text for tokens only when actually
	needed, which should speed compilation up somewhat.
	Change to allow INCLUDE at any point where a statement
	can end, i.e. in ffelex_finish_statement_ or when a SEMICOLON
	token is sent.
	Remove some old, obsolete code.
	Clean up layout of entire file to improve formatting,
	readability, etc.
	(ffelex_set_expecting_hollerith): Remove include argument.

	backslash processing.

	* std.c (ffestd_R1001dump_): Don't assume CHARACTER and

	ffecom_3s, &c): Check all inputs for error_mark_node.
	(ffecom_start_progunit_): Don't transform all symbols

	so that assignment-like concatenation is allowed for ICHAR(),
	IACHAR(), and LEN() intrinsics.
	(ffeexpr_reduced_*_): Say "an array" instead of "an entity" in
	diagnostics, since it's more informative.
	(ffeexpr_finished_): For many contexts, check for null expression
	and array before trying to do a conversion, to avoid redundant

	to pointer-to-function, not function.
	(ffecom_expr_): Use ffecom_arg_ptr_to_expr instead of

	be smaller.

	* equiv.c (ffeequiv_offset_): Check symbol info for ANY.

	* expr.c (ffeexpr_find_close_paren_, ffeexpr_nil_*): New functions
	to handle following the contour of a rejected expression, so
	statements like "PRINT(I,I,I)=0" don't cause the PRINT statement
	code to get the second passed back to it as if there was a
	missing close-paren before it, the comma causing the PRINT code
	to confirm the statement, resulting in an ambiguity vis-a-vis
	the let statement code.
	Use the new ffecom_find_close_paren_ handler when an expected
	close-paren is missing.
	(ffeexpr_isdigits_): New function, use in all places that
	currently use isdigit in repetitive code.
	(ffeexpr_collapse_symter): Collapse to ANY if init-expr is ANY,
	so as to avoid having symbol get "transformed" if used to
	dimension an array.
	(ffeexpr_token_real_, ffeexpr_token_number_real_): Don't issue
	diagnostic about exponent, since it'll be passed along the
	handler path, resulting in a diagnostic anyway.

	about conflict between "SAVE" by itself and other uses of
	SAVE only in pedantic mode.

	making a VAR_DECL with error_mark_node as its type.

	* ste.c (ffeste_begin_iterdo_): Convert itercount to INTEGER
	anytime calculation of number of iterations ends up with type
	other than INTEGER (e.g. DOUBLE PRECISION, REAL).

	(non-statement-function) f2c functions.
	(ffecom_init_0): ffecom_tree_fun_type[][] and _ptr_to_*_* are
	really f2c-interface arrays, so use base type void for COMPLEX
	(like CHARACTER).

	* Make-lang.in (f77.install-common): Expurgate the test for and

	add appropriate commentary.

	* com.c (ffecom_return_expr): Check TREE_USED to determine
	where return value is unset.

	* com.h (struct _ffecom_symbol_): Add note about length_tree
	now being used to keep tree for ASSIGN version of symbol.

	* com.h (ffecom_expr_assign, ffecom_expr_assign_rw): New decls.
	(error): Add this prototype for back-end function.

	* fini.c (main): Grab input, output, and include names
	directly off the command line instead of making the latter
	two out of the first.

	* lex.c: Improve tab handling for both fixed and free source
	forms, and ignore carriage-returns on input, while generally
	improving the code.  ffelex_handle_tab_ has been renamed and
	reinvented as ffelex_image_char_, among other things.

	* malloc.c, malloc.h: Switch to valid ANSI C replacement for
	ARRAY_ZERO, and kill the full number of bytes in pools and
	areas.

	* proj.h.in (ARRAY_ZERO, ARRAY_ZERO_SIZE): Remove.

	* ste.c (ffeste_io_cilist_, ffeste_io_icilist_, ffeste_R838,

	ARRAY_ZERO.

Fri Feb 17 03:35:19 1995  Craig Burley  (burley@gnu.ai.mit.edu)

	* Version 0.5.8 released.

	* INSTALL: In quick-build case, list g77 target first so g77
	gets installed.  Also, explain that gcc gets built and installed
	as well, even though this isn't really what we want (and maybe
	we'll find a way around this someday).

Fri Feb 17 02:35:41 1995  Craig Burley  (burley@gnu.ai.mit.edu)

	* Version 0.5.7 released.

	* Makefile.in (CONFIG_H, HCONFIG_H, TCONFIG_H, TM_H): Remove
	../ prefix in front of .h files, since they're in the cd.

Fri Feb 17 01:50:48 1995  Craig Burley  (burley@gnu.ai.mit.edu)

	* Version 0.5.6 released.

Thu Feb 16 20:26:54 1995  Craig Burley  (burley@gnu.ai.mit.edu)

	* ../README.g77: Remove description of g77 as "not-yet-published".

	* CREDITS: More changes.

	* Make-lang.in (G77STAGESTUFF): Remove cktyps stuff.

	* Makefile.in (CONFIG_H, HCONFIG_H, TCONFIG_H, TM_H): Don't
	prefix gcc dir with $(srcdir) since these don't live there,
	they are created in the build dir by gcc's configure.  Add
	a note explaining what these macros are about.
	Update dependencies via deps-kinda.

	* README.NEXTSTEP: Credit Toon, and per his request, add his
	email address.

	* com.h (FFECOM_DETERMINE_TYPES): #include "config.j".

	* config.j, convert.j, flags.j, hconfig.j, rtl.j, tconfig.j,
	tm.j, tree.j: Don't #include if already done.

	* convert.j: #include "tree.j" first, as convert.h clearly depends
	on trees being defined.

	* rtl.j: #include "config.j" first, since there's some stuff
	in rtl.h that assumes it has been #included.

	* tree.j: #include "config.j" first, or real.h makes inconsistent
	decision about return type of ereal_atof, leading to bugs, and
	because tree.h/real.h assume config.h already included.

Wed Feb 15 14:40:20 1995  Craig Burley  (burley@gnu.ai.mit.edu)

	* Version 0.5.5 released.

	Document and explain this rule a bit better.
	Accommodate changes in output of gcc -MM.

	* *.h, *.c: Change #include's so proj.h not assumed to #include
	malloc.h or config.h (now config.j), and so new .j files are
	used instead of old .h ones.

	* com.c (ffecom_init_0): Use FLOAT_TYPE_SIZE for f2c's
	TYLONG/TYLOGICAL type codes, to get g77 working on Alpha.

	* com.h: Make all f2c-related integral types "int", not "long
	int".

	* config.j, convert.j, flags.j, glimits.j, hconfig.j, rtl.j,
	tconfig.j, tm.j, tree.j: New files wrapping around gbe
	.h files.

	* config.h, convert.h, flags.h, glimits.h, hconfig.h, rtl.h,
	tconfig.h, tm.h, tree.h: Deleted so new .j files
	can #include the gbe files directly, instead of using "../",
	and thus do better with various kinds of builds.

	* proj.h: Delete unused NO_STDDEF and related stuff.

Tue Feb 14 08:28:08 1995  Craig Burley  (burley@gnu.ai.mit.edu)

	as prefix on any diagnostic without pointers into source.

	* bad.def (FFEBAD_TOO_BIG_INIT): Add this warning message.

	* config-lang.in: Add Dave Love's patch to catch case where
	back-end patches not applied and abort configuration.

	* data.c (ffedata_gather_, ffedata_value_): Warn when about
	to initialize a large aggregate area, due to design flaw resulting
	in too much time/space used to handle such cases.
	Use COMMON area name, and first notice of symbol, for multiple-
	initialization diagnostic, instead of member symbol and unknown
	location.
	(FFEDATA_sizeTOO_BIG_INIT_): New macro per above.

Mon Feb 13 13:54:26 1995  Dave Love  <d.love@dl.ac.uk>

	* Make-lang.in (F77_SRCS): Use $(srcdir)/f/proj.h.in, not
        $(srcdir)/f/proj.h for build outside srcdir.

	* Version 0.5.4 released.

	* Make-lang.in (f/proj.h): Reproduce this rule here from
	Makefile.in.
	($(srcdir)/f/conf-proj): Put autoconf's stdout in temp file
	conf-proj.out, then mv to conf-proj only if successful, so
	conf-proj not touched if autoconf not installed.

	* Makefile.in ($(srcdir)/conf-proj): See Make-lang.in's similar
	rule.

Sat Feb 11 20:56:02 1995  Craig Burley  (burley@gnu.ai.mit.edu)

	* BUGS: Clarify some bugs.

	* DOC: Many improvements and fixes.

	* README: Move bulk of text, edited, to ../README.g77, and
	replace with pointer to that file.

	* com.c (ffecom_init_0): Comment out warning about sizeof(ftnlen)
	as per ste.c change.  Add text about ASSIGN to help user understand
	what is being warned about.

	* com.c (ffecom_vardesc_): Crash if typecode is -1.

	* ste.c (ffeste_io_dolio_): Crash if typecode is -1.

Sat Feb 11 09:51:57 1995  Craig Burley  (burley@gnu.ai.mit.edu)

	* ste.c: In I/O code tests for item arrayness, sort of revert
	to much earlier code that tests original exp, but also check
	in newer way just in case.  Newer way alone treated FOO(1:40)
	as an array, not sure why older way alone didn't work, but I
	think maybe it was when diagnosed code was involved, and
	since there are now checks for error_mark_node, maybe the old
	way alone would work.  But better to be safe; both original
	ffebld exp _and_ the transformed tree must indicate an array
	for the size-determination code to be used, else just 1/2 elements
	assumed.  And this text is for EMACS: (foo at bar).

Fri Feb 10 11:05:50 1995  Craig Burley  (burley@gnu.ai.mit.edu)

	* ste.c: In many cases, surround statement-expansion code
	with ffecom_push_calltemps () and ffecom_pop_calltemps ()
	so COMPLEX-returning functions can have temporaries pushed
	in "auto-pop" mode and have them auto-popped at the end of
	the statement.

	* stc.c (ffestc_R501_item): Don't reset kind/where to NONE when
	setting basictype/kindtype info for symbol, or especially
	its function/result twin, because kind/where might not be NONE.

Tue Feb  7 14:47:26 1995  Dave Love  <d.love@dl.ac.uk>

	* Make-lang.in (include/f2c.h:): Set shell variable src more

	(BITS_PER_WORD etc.) Remove and use conditional definitions to com.h.

	* runtime/configure.in: #define FFECOM_DETERMINE_TYPES for com.h in
	f2c type determination.

	* tm.h: Remove (at least pro tem) because of relative path and use
	top-level one.

	* Make-lang.in (include/f2c.h:): Set shell variable src more
	robustly (independent of whether srcdir is relative or absolute).
	* Makefile.in (f/proj.h:): Likewise.

Fri Feb  3 20:33:14 1995  Craig Burley  (burley@gnu.ai.mit.edu)

	* g77.c (main): Treat -l like filename in terms of -x handling.
	Rewrite arglist mechanism for ease of maintenance.
	Make sure every -lf2c is followed by -lm and vice versa.

	* Make-lang.in: Put complete list of sources in F77_SRCS def
	so changing a .h file, for example, causes rebuild.

	* Makefile.in: Change test for nextstep to m68k-next-nextstep* so
	all versions of nextstep on m68k get the necessary flag.

Fri Feb  3 19:10:32 1995  Dave Love  <d.love@dl.ac.uk>

	* config-lang.in: Comment out more of f2c rules (c.f. Make-lang.in).
	(This stuff is relevant iff you gave configure --enable-f2c.)
	Create f/runtime directory tree iff not building in source
	directory.

	* Makefile.in (srcdir): Append slash so we get the right value when
	not building in the source directory.  This is a consequence of not
	building the `f' sources in `f'.
	(VPATH): Override configure's value for reasons above.

	Recognize both `-xlang' and `-x lang'.
	Recognize `-xnone' and `-x none' to mean what it does, instead
	of treating "none" as any other language.
	Some minor, slight improvements in the way args are handled
	(hopefully for clearer, more maintainable code), including
	consistency checks on arg count just in case.

Wed Jan 18 16:41:57 1995  Craig Burley  (burley@gnu.ai.mit.edu)

	* DOC: Explain -fautomatic better.

	* INSTALL: Describe libf2c.a better.

	6000000.  Fix typo.  Change deps-kinda target to handle building
	from gcc/.  Update dependencies.

	stuff.
	Remove consistency tests that cause compiler warnings.

	* cktyps.c: Remove all typing checking.

	to precisely match how they're declared in libf2c.

	* com.h, com.c: Revise to more elegantly track related stuff
	in the version of f2c.h used to build libf2c.

	* com.c: Increase FFECOM_sizeMAXSTACKITEM, and if 0 or undefined
	when checked to determine where to put entity, treat as infinite.
	Rewrite temporary mechanism to be based on trees instead of
	ffeinfo stuff, and make it much simpler.  Change interface
	accordingly.
	Fixes to better track types of things, make appropriate
	conversions, etc.  E.g. when making an arg for a libf2c
	function, make sure it's of the right type (such as ftnlen).
	Delete opBACKEND transformation code.
	(ffecom_init_0): Smoother initialization of types, especially
	paying attention to using consistent rules for making INTEGER,
	REAL, DOUBLE PRECISION, etc., and for deciding their "*N"
	and kind values that will work across all g77 platforms.
	No longer require per-target configuration info in target.h
	or config/*/*; use new type module to store size, alignment.
	(ffecom_member_phase2): Declare COMMON/EQUIVALENCE group members
	so debugger sees them.
	(ffecom_finish_progunit): Transform all symbols in program unit,
	so -g will show they all exist.

	* expr.c (ffeexpr_collapse_substr): Handle strange substring
	range values.

	* info.h, info.c: Provide connection to new type module.
	Remove tests that yield compiler warnings.

	* stc.c (ffestc_kindtype_kind_, ffestc_kindtype_star_): Replace
	boring switch stmt with simple call to new type module.  This
	sort of thing is a reason to get up in the morning.

	* ste.c: Update to handle new interface for
	ffecom_push/pop_tempvar.
	Fixes to better track types of things.
	Fixes to not crash for certain diagnosed constructs.
	(ffeste_begin_iterdo_): Check only constants for overflow to avoid
	spurious diagnostics.
	Don't convert larger integer (say, INTEGER*8) to canonical integer
	for iteration count.

	* stw.h: Track DO iteration count temporary variable.

	* symbol.c: Remove consistency tests that cause compiler warnings.

	* target.c (ffetarget_aggregate_info): Replace big switch with
	little call to new type module.
	(ffetarget_layout): Remove consistency tests that cause
	compiler warnings.
	(ffetarget_convert_character1_typeless): Pick up length of
	typeless type from new type module.

	* target.h: Crash build if target float bit pattern cannot be
	precisely determined.
	Remove all the type cruft now determined by ffecom_init_0
	at invocation time and maintained in new type module.
	Put casts on second arg of all REAL_VALUE_TO_TARGET_DOUBLE
	uses so compiler warnings avoided (requires target float bit
	pattern to be precisely determined, hence code to crash build).

	* top.c: Add inits/terminates for new type module.

	* type.h, type.c: New module.

	* gbe/2.6.2.diff: Remove all patches to files in gcc/config/

Thu Nov 17 15:18:05 1994  Craig Burley  (burley@gnu.ai.mit.edu)

	* Version 0.5.2 released.

	* bad.def: Modify wording of FFEBAD_UNIMPL_STMT to indicate
	that it covers a wide array of possible problems (that, someday,
	should be handled via separate diagnostics).

	* lex.c: Allow $ in identifiers if -fdollar-ok.
	* top.c: Support -fdollar-ok.
	* top.h: Support -fdollar-ok.
	* target.h: Support -fdollar-ok.
	* DOC: Describe -fdollar-ok.

	* std.c (ffestd_R1229_finish): Fix bug so stand-alone build works.
	* ste.c (ffeste_R819A): Fix bug so stand-alone build works.

	* Make: Improvements for stand-alone build.

	* Makefile.in: Fix copyright text at top of file.

	* LINK, SRCS, UNLINK: Removed.  Not particularly useful now that
	g77 sources live in their own subdirectory.

	* g77.c (main): Cast arg to bzero to avoid warning.  (This is
	identical to Kenner's fix to cp/g++.c.)

	* gbe/: New subdirectory, to contain .diff files for various
	versions of the GNU CC back end.

	* gbe/README: New file.
	* gbe/2.6.2.diff: New file.

Tue Nov  8 10:23:10 1994  Dave Love  <d.love@dl.ac.uk>

	* Make-lang.in: don't install as f77 as well as g77 to avoid
	confusion with system's compiler (especially while testing)

	* g77.c (main): use -lf2c and -lm; fix sense of test for .f/.F files
