[Bug ada/34289] New: Systematic recompilation of up-to-date object files when using the "-s" gnatmake option GNAT 4.3.0 on x86-*-Darwin8

[bechir dot zalila at gmail dot com]

Hi,

When recompiling an Ada file (attachements p.ads p.adb) using "-s" option for
gnatmake. The object file is systemtically rebuild even if it is up-to-date and
if even the compiler flags have not changed.

* How to reproduce the bug:
===========================

INPUT FILES:
============

Attached p.ads and p.adb

COMMAND LINE:
=============

Two successive executions of:

gnatmake -s p.adb

EXPECTED BEHAVIOR:
==================

first: gnatmake -s p.adb

gcc -c p.adb

second: gnatmake -s p.adb

<nothing> (object file is up to date, thus it is not recompiled)

ACTUAL BEHAVIOR:
================

first: gnatmake -s p.adb

gcc -c p.adb

second: gnatmake -s p.adb

gcc -c p.adb

Object file is recompiled systematically at each execution

MINI DIAGNOSTIC:
================

If we use the -v flag of gnatmake, we get the following output:

GNATMAKE  4.3.0 20071119 (experimental)
Copyright (C) 1995-2007, Free Software Foundation, Inc.
  "p.ali" being checked ...
  -> "p.adb" different number of switches
-mmacosx-version-min=10.4

gcc -c p.adb
End of compilation

The command line option '-mmacosx-version-min=10.4' is added automatically 
by gcc when calling gnat1.

Passing -v to gcc (gcc -v -c p.adb) gives the following (truncated) output:

.../gnat1 -quiet -dumpbase p.adb -mmacosx-version-min=10.4 -mtune=generic -fPIC
p.adb -o /var/tmp//ccqsMDI3.s

...

There are indeed several options added by gcc to gnat1 (especially
-mmacosx-version-min=10.4 and -mtune=generic). But for some reason, only
-mmacosx-version-min=10.4 causes the problem.

[Bug ada/34289] Systematic recompilation of up-to-date object files when using the "-s" gnatmake option GNAT 4.3.0 on x86-*-Darwin8

[bechir dot zalila at gmail dot com]

------- Comment #3 from bechir dot zalila at gmail dot com  2007-11-30 09:19 -------
In gcc/config/i386/darwin.h, we can see:

#define CC1_SPEC "%(cc1_cpu) \
  %{!mkernel:%{!static:%{!mdynamic-no-pic:-fPIC}}} \
  %{!mmacosx-version-min=*:-mmacosx-version-min=%(darwin_minversion)} \
  %{g: %{!fno-eliminate-unused-debug-symbols: -feliminate-unused-debug-symbols
}}"

which cintains the addition of -mmacosx-version-min=... if it is not given,

In gcc/ada/lang-spec.h we can see the following:

%{O*} %{W*} %{w} %{p} %{pg:-p} %{a} %{f*} %{d*} %{g*&m*} "
#if defined(TARGET_VXWORKS_RTP)
   "%{fRTS=rtp:-mrtp} "
#endif
#if CONFIG_DUAL_EXCEPTIONS
   "%{fRTS=sjlj:-fsjlj} "
#endif
   "%1 %{!S:%{o*:%w%*-gnatO}} \

The %1 (processing of CC1_SPEC) comes after the %{g*&m*} which should result in
adding the -mmacosx-version-min=... after all options that begins with -g* and
especially -gnatez, and it should not be added in the .ali file. For some
reason, the -mmacosx-version-min=... is added before all options that begins
with -g...

I replaced %{g*&m*} by %{g*} %{m*} in lang-specs.h and this solved the problem.
However, I don't know whether its is very important to conserve the order among
-g* and -m* switches when passing them to gnat1. The change 83658 did not say
why:

* lang-specs.h: Keep -g and -m switches in the same order, and as the
last switches.

Note that it may have been perfectly valid in 2004 as this target was not

Ok, the problem here is that "-mmacosx-version-min=10.4" should appear *after*
"-gnatez" not to be remembered in the ALI file:

COLLECT_GCC_OPTIONS='-mmacosx-version-min=10.4' '-c' '-v' '-gnatez'

This patchfile solves the problem by adding a new switch (-gnatea) analog to 
-gnatez . -gnatea and -gnatez surround the switches we want to store in the ALI
file.

------- Comment #11 from bechir dot zalila at gmail dot com  2007-12-03 14:00 -------
After a lot of investigation, I succeeded to isolate the problem. The added
-mmacosx-min-version is not done when processing the CC1_SPEC: It is done in
the main function in gcc.c using the GCC_DRIVER_HOST_INITIALIZATION macro.

In gcc.c (function main):

#ifdef GCC_DRIVER_HOST_INITIALIZATION
  /* Perform host dependent initialization when needed.  */
  GCC_DRIVER_HOST_INITIALIZATION;
#endif

For the darwin (ppc + x86): in config/darwin.g:

extern void darwin_default_min_version (int * argc, char *** argv);
#define GCC_DRIVER_HOST_INITIALIZATION \
  darwin_default_min_version (&argc, &argv)
#endif /* CROSS_DIRECTORY_STRUCTURE */

And finally the darwin_default_min_version function defined in
config/darwin-driver.c. This function inserts -mmacosx-version-min
*at the beginning* of argv, just after the command name (argv[1])

I Attached a patchfile (gcc_ada.diff) for the GNAT frontend that solves the
problem
