stop using P_, __P in header files

stop using P_, __P in header files

[Dan Nicolaescu]

emacs-24 would be a good target to switch to standard C.
We are already using standard C features, so a K&R compiler cannot be
used to compile emacs anymore.

The first step for the transition could be to remove all P_ and __P
(and maybe other variations) macros in header files.

Help doing this would be appreciated.

I have removed them* from all header files, and I'm now expurging them
from .c sources. I'll have the patch ready by tomorrow.

* just P_ and __P; I didn't look for other variations.

Another desired standard C feature would be to use memcpy/memset/memcmp
throughout instead of the non-standard bcopy/bzero/bcmp.  I have a patch
for that, but it is incomplete in that it breaks profiling builds.

I didn't see this mail before checking in, sorry.  I committed fixed .h-files 
except for w32 and dos which I can't verify.

Should we do .c and .m files also?

Please clean up also the w32/msdos files. We'll fix any possible breakage.

Yes, please, and then remove the definitions of _P and P__, which will
no longer be necessary.

The DOS port compiles fine with revno 100685.  Thanks.

Yes, definitely.  I think it's not a good idea to modify prototypes in
the header files while leaving the implementation in its old K&R form.

Did you keep __P on lib-src/ctags.c on purpose?

And should we also remove PP from src/gmalloc.c?

Not sure what you mean, I have no lib-src/ctags.c.  If you mean etags.c, I 
removed it.

You're right. On Windows, ctags.c is copied from etags.c. I imagine on
GNU/Linux ctags will be a link to etags, to start it under another
name, or somesuch.

Thanks!  (This was extremely quick!!!)

I think the next step is to compile with -Wstrict-prototypes and fix
up some of the prototypes that use just "()" instead of "(void)" (or the proper types).
[I have a patch to add -Wstrict-prototypes in configure, but that will
give too many warnings while we still have K&R function definitions, so it will wait].

Seconded.
protoize should do most of the work, it won't do it for DEFUNs though.
Help would be appreciated.

Great!  Thanks!

BTW, what do you think about having a setup to compile with -flto?
Should we do it?  How?  Or is it too early for that?

No, there's no link.  Simply, etags.c is compiled with -DCTAGS on the
command line:

    ## We depend on etags to assure that parallel makes do not write two
    ## etags.o files on top of each other.
    ctags${EXEEXT}: etags${EXEEXT}
	    $(CC) ${ALL_CFLAGS} -DCTAGS -DEMACS_NAME="\"GNU Emacs\"" \
	      -DVERSION="\"${version}\"" ${srcdir}/etags.c $(GETOPTOBJS) \
	      $(REGEXPOBJ) $(LOADLIBES) -o ctags

Btw, that comment doesn't make sense, since no etags.o is produced.

I converted the lib-src directory using protoize on a GNU/Linux
machine.  As protoize runs the preprocessor, it's surely not enough,
but it's a start...

Then we should update the comment with this info, IMO.

Thanks. I've fixed a few prototypes that break compilation on Windows
or generate warnings.

A few questions:

1) This one and similar ones on unexelf.c seem errors:

-round_up (x, y)
-     ElfW(Addr) x, y;
+round_up (Elf32_Addr x, Elf32_Addr y)

The prototypes should presumably still use ElfW(Addr), ElfW(Ehdr),
etc., shouldn't they?

2) In strftme.c you've converted just some functions, not all, and
removed the LOCALE_PARAM* macros.

 static CHAR_T *
-memcpy_lowcase (dest, src, len LOCALE_PARAM)
-     CHAR_T *dest;
-     const CHAR_T *src;
-     size_t len;
-     LOCALE_PARAM_DECL
+memcpy_lowcase (char *dest, const char *src, size_t len)

Apparently, there haven't been any changes from gnulib merged back
into strftime.c in the past seven years (since 2003-06-24). Should the
LOCALE_PARAM* macros still be used (and so, re-added to
memcpy_(low|upp)case), or would it be better to just get rid of that
cruft?

3) After this change in print.c

 static void
-strout (ptr, size, size_byte, printcharfun, multibyte)
-     char *ptr;
-     int size, size_byte;
-     Lisp_Object printcharfun;
-     int multibyte;
+strout (char *ptr, int size, int size_byte, Lisp_Object printcharfun,
int multibyte)
 {

compilation throws this warning:

print.c: In function 'print_object':
print.c:1973: warning: passing argument 1 of 'strout' discards
qualifiers from pointer target type
print.c:353: note: expected 'char *' but argument is of type 'const char *'

becase of the call

	  strout (XSUBR (obj)->symbol_name, -1, -1, printcharfun, 0);

AFAICS, the object pointed to by PTR is never modified, so it seems
safe to use const char *, and I've done so.

Yes, they should.  I did not convert the code by hand, but by using
protoize (which runs the preprocessor) so this is why such prototypes got changed.
I caught a few similar ones and worked around them, but it looks like
some similar things got away.

I'd say we should resync with gnulib.
protoize made this change, so it was not intentional...

OK, committed.

> I'd say we should resync with gnulib.
> protoize made this change, so it was not intentional...

Because of the different syntax in prototypes versus K&R, instead of
LOCALE_PARAM_DECLR we should now use LOCALE_PARAM_PROTO

-memcpy_lowcase (char *dest, const char *src, size_t len)
+memcpy_lowcase (CHAR_T *dest, const CHAR_T *src, size_t len
+		LOCALE_PARAM_PROTO)

-memcpy_uppcase (char *dest, const char *src, size_t len)
+memcpy_uppcase (CHAR_T *dest, const CHAR_T *src, size_t len
+		LOCALE_PARAM_PROTO)

which is a bit weird because it goes against the LOCALE_PARAM* use on
strftime.c. It would be possible to redefine L_P_DECL:

# define LOCALE_PARAM_DECL , __locale_t loc

and keep the old code, but there are other functions in the file that
have not been converted.

As strftime.c is maintained outside of Emacs, I'd suggest just
reverting the change and leaving the K&R code as it was. Seems cleaner
that a mixup of styles.

[hmm, the original version of this got returned, maybe because of the
400KB attachment, trying without it to see if it makes it, I'll split
the attachment in smaller pieces and send it separately]

I've done most of this.

There are some remaining issues to solve:

- DEFUNs need to be converted by hand, protoize does not know anything about them.

- the error and message functions in lisp.h are called with variable
  number of arguments, but are defined with a fixed number of arguments.

- xdisp.c cm.c term.c eval.c process.c image.c keyboard.c buffer.c
vm-limit.c get some warnings that looked a bit odd at first sight, so
I didn't check them in (some are due to error/message mentioned
above).  I attach them here in case someone wants to take a look and
fix any issue and check in the conversion.

(By *hand*??  Ugh.  We really need a tool that implements some kind of editing macros... :-)

Also, I believe make-docfile scans the argument lists; it may need to be taught about the new syntax.

Or, the explicit old-style argument declarations can go away, and DEFUN can be taught how to expand a list of argument names into a list of new-style argument declarations.  I thought about doing this back in May when we were discussing the DOC file name handling and version number definition; I think it would require making a bunch of helper macros for each MAXARGS value that could get passed.  (I was thinking about it in the context of putting the doc strings in a section of the executable that only gets paged in when needed on most platforms, rather than having to copy them to and then load from a separate file.)

They should probably be fixed to be standard variadic functions, which means doprnt() has to be taught about va_arg.  I can take a shot at that, if no one else feels like it; it's probably easy.


We could also probably ditch the "register" declarations that date back to pre-GCC days; do they do *any* good now?

This patch includes your original changes for buffer.c, keyboard.c,
process.c and xdisp.c, plus a few fixes. With them, they compile
correctly on my system.

Could you please check whether they cause any trouble in your setup?

Re: stop using P_, __P in header files

Correction: please add the "volatile" keyword to arg 3 of `keyremap_step':

keyremap_step (Lisp_Object *keybuf, int bufsize, volatile keyremap *fkey,
	       int input, int doit, int *diff, Lisp_Object prompt)

Or, alternatively: does anyone know why read_key_sequence does have a
ton of `volatile' variables? Do really all of then need to be
volatile?

[-- Attachment #1: Type: text/plain, Size: 448 bytes --]

Attached is rem2.diff, which includes your eval.c and term.c. Differences:

 - the error functions that have been reverted to K&R (they should be
converted to standard variadic functions, like Ken suggested)
 - a few fixes

They compile fine on my setup.

Finally: cm.c, image.c and vm-limit.c do not cause any trouble on
Windows (cm.c is not used, in fact). I'll try on Ubuntu, but if you
have a log of the error you saw, that'd help.

Please do.

That'd be great.

To summarize, I'm attaching a new patch will all pending files,
including cm.c, image.c and vm-limit.c. It fixes (or works around) all
problems I see on Windows or Ubuntu.

Notes:
 - keymap.c:keyremap_step()  has now an argument with the volatile
specifier, which is unclean but apparently necessary.
 - variadic error functions in eval.c and term.c have been reverted to
their previous K&R state.
 - cm.c:cmputc() has now arg of type int (as tputs expects) instead of
char. If that causes trouble with signed/unsigned conversion, casting
will be required.

Enjoy,

    Juanma

True, but "register" never was more than a hint to the compiler.
Surely most modern compilers do a better work on optimizing code on

Of course not, although I suspect most UNIX installations use it.  By "pre-GCC" I meant, what, late '80s or early '90s, before GCC came into widespread use?  When commonly used optimizer technology wasn't nearly as good as it is now.  Do the non-GCC compilers (those that have halfway decent optimizers -- those that don't should only be used for bootstrapping GCC or other modern compilers) still need "register" these days to indicate what variables belong in registers, or do the optimizers do a reasonable job of working it out for themselves?

Please do. [I have a patch to turn on -Wstrict-prototypes by default
if available, but it would produce 4 warnings per file including
lisp.h, so it won't be very popular until the above is fixed].

This would be a different approach for tackling the same problem.  Question is, do we want the explicit argument types in each function, and more work for make-docfile, or keep things simple for make-docfile and macro-expand the argument name list into appropriate declarations?  The set of macros would basically be parallel to the existing DEFUN_ARGS_* macros, except with names to substitute.

Either leave the arg list unspecified, or we have to do a bunch of casting; I don't think there are any other options...

I'm not an expert, so I don't know.  Maybe someone else could chime
in.  One issue that I'd be interested in is to know whether GCC uses
this hint at some low optimization level, because I frequently need to
use -O1 or -O0 to get a binary I can debug without getting older by
the hour.

> Surely most modern compilers do a better work on optimizing code on

FWIW, the ones I put in some code I wrote long ago were not naive at
all.  And I don't think those we have in Emacs are naive, either.  But
if these hints are not used, it doesn't really matter.

From skimming some GCC code, it looks to me like either having the optimizer on, or using "register", may cause registers to be used.  (Specifically, if the optimizer is off and "register" is not used, then automatic variables appear to get stack slots unconditionally; otherwise, types and other restrictions permitting, they get "pseudo-registers" which may be assigned either registers or stack slots.)  So, for -O0, the register declarations might make a difference (I don't know how good the "stupid" allocator is for non-optimizing compiles), though my attitude is generally that for -O0, performance considerations don't matter much...  For -O1, I don't think the register declarations matter.

If we assume we don't have to tune the code for builds without decent optimization (including gcc -O0), I think at least some of them are kind of useless -- like any place where *all* the non-addressable variables are declared "register".  If that's a meaningful hint these days, the compiler's not doing a very good job.  Back in the '80s, when PCC was one of the more popular compilers around, you had to say "register" or everything would go in stack slots, even with the optimizer on.  And the first N register variables got assigned to a specific set of machine registers -- I recall working with VAX BSD kernel code that made use of known registers this way.  So for small functions, it made sense to make everything "register", when that was the common technology.

After a quick "grep register *.[chm]", the first one I pulled up was data.c:Fsetq_default, where all the automatic variables but "gcpro1" are "register", though the argument wasn't.  Next was data.c:Fneq, where both arguments are.  In data.c:Fash, all arguments and automatics are.  These really look like cases of PCC workarounds.  In dbusbind.c:Fdbus_method_return_internal, only "args" is; maybe that's possibly helpful, to some compiler somewhere; but shouldn't a decent optimizer figure it out from the large number of uses of the variable?

No offense intended, so please excuse my choice of words.

My point was that, when the code was written, the register
declarations perhaps helped the optimizer (depending of compiler,
processor architecture, number of available registers, etc.). Today,
it's quite likely they don't. ISTR reading about programs that got a
noticeable speedup when "register" was removed altogether from the
code... Of course I don't think that'll be the case with Emacs, but
I'd bet all of a full euro that there won't be any noticeable
slowdown, either.

IMHO the simplest solution should be done first.

Using a union for lisp.h:Lisp_Subr.function works too (I have a patch
ready to go).  A single cast is needed in DEFUN.  (with designated
initializers no cast should be needed, but that's many years away).

No offense taken, so there's nothing to apologize for.

Why don't you try if it makes any difference?
Add 
#define register
at the beginning of a C file, after all the #includes and then check if there's any code
generation difference.

In principle, "register" is still occasionally useful.  If you have a
large number of variables in a loop which has two long branches, then
which variables belong in registers depend on which branch is taken
more often, something that the compiler cannot know.

OTOH, without profiling typically the programmer won't know, either.

Also, "large" depends on the number of registers available, of course.
In the case of x86, "large" is pretty small, about 8-10 IIRC.

If the compiler pays attention to them, yes, it could help.  Though for reasons other than register allocation it's probably more useful to tell the compiler which branches are taken most often, though unfortunately that's still compiler-specific (e.g., __builtin_expect, or feedback from profiling runs).

Fewer -- x86 has 8 integer registers including stack pointer and frame pointer, and some are clobbered in function calls.  Slap too many "register" declarations onto variables and the compiler is still going to have to guess which of them should actually be heeded.  But if you keep the number small, you can't give the compiler much advice on x86-64 or ppc or other platforms with many more registers available.

I will (grudgingly :-) admit there's sometimes a need to give the compiler some hints that it can't necessarily work out for itself.  But I think the use of "register" in Emacs goes well beyond that, as I pointed out regarding some functions in data.c.  And I suspect any significant fine-tuning with register declarations is likely to be specific to an architecture and/or compiler.

Agreed, but until it becomes standardized, that leads to really ugly
code if you try to make things work across compilers.  "register", on
the other hand, is part of the language.

I meant the number of variables to be allocated to registers.  The
principle is only interesting if there's a branch, and you care most
about variables that are frequently accessed on one branch but not the
other.  So make that 4-5 registers being allocated; on x86, more than
that number of register declarations doesn't help and could even hurt
if the compiler respects the programmer's judgment too much.

If you've got a lot of registers, then (for code written by humans,
anyway), I don't think it likely you'd need to give the compiler much
advice.

Sure, I'd go so far as to say that "s/register //g" would be a great
idea in that file.  You did ask if "register" was *ever* useful,
though.  I'm sure the answer to that is still "yes".  (I have to admit
that after looking at data.c again, I'm completely in sympathy with
compilers that count the number of register declarations and ignore
all of them if there are more than one per hundred lines. :-)

For modern compilers, actually I would guess not, because I think the
useful cases are limited to your "grudging admission", where the
compiler truly can use a hint because the branch frequencies are
data-dependent or something.  That's not going to be compiler-
dependent (assuming you don't opt for informing the compiler of branch
frequencies).  As for architecture, I'd say what a human programmer
can do to give good advice is probably limited to x86 levels of
register poverty, so more than 3 or 4 register declarations is
probably not ever worth the effort (and will be a no-op on register-
rich architectures, of course).

At -O0 you have bigger code quality problems (especially with gcc)
than "register".

A reference to comp.lang.C FAQ:

http://c-faq.com/~scs/cclass/krnotes/sx7f.html

And that's from the mid 90's.

AFAIK the register allocator in gcc does not try to look at "register".

Naive or not, "register" is a guarantee that noone is going to take or
store the address of the named variable.  For compilers not building a
complete parse tree before code generation, that can be useful
information.

Agreed.

But the question still stands: are there many current compilers who
benefit from register declarations, and if so, it is enough of an
improvement to make a difference?

On the computers I use, there's not that much difference even between
optimized and non-optimized Emacs builds (with GCC 3.X and 4.X).
