[Bug libfortran/30617] recursive I/O hangs under OSX
--- Comment #16 from dominiq at lps dot ens dot fr 2007-02-08 08:45 --- Subject: Re: recursive I/O hangs under OSX Try : ... Or increase the size of string. I have increased the length to 20 and in both cases the executable (for an invalid code!-) works on OSX. I have also tried: external fun character(20) :: fun i=2 print trim(fun(i)), 99 end function fun(i) character(20) :: fun integer :: i write(fun,'(A2,I0,A)') (I, I, ) end which works. Is this last code valid for f95 (-std=f95 does give any diagnostic) and/or f2003? Anyway the hanging seems due to the recursive access to external I/O. If I want to corner the problem, where should I look? With directions I can try to locate the problem and test possible fixes. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=30617

Note that the warning is emitted because we change n -= 2 to n += 4294967294 (oops).

[Bug libfortran/30617] recursive I/O hangs under OSX
--- Comment #17 from jakub at gcc dot gnu dot org 2007-02-08 09:36 --- When writing the unit locking code, I relied on Fortran95 requiring that the same unit isn't used recursively, you can use different units, but not the same. gfortran.dg/intrinsic_actual_2.f90 fails on Linux too when linked with -fopenmp (or -lpthread, -fopenmp implies that), but that is fine, the testcase is IMHO not valid Fortran95 source. Now, if Fortran2003 allows some recursive access to the same unit (under which conditions?), then the gfc_unit's lock could very well be changed into __gthread_recursive_mutex_t as well as the initializer, perhaps together with adding a recursion count (as the recursion count in __gthread_recursive_mutex_t isn't portably accessible) to gfc_unit as well. The question is how much is libgfortran prepared for changes happening to gfc_unit happening between say st_write and st_write_done calls (st_write normally calls get_unit and thus acquires gfc_unit's lock, which is held until st_write_done calls unlock_unit). For Fortran95, if a hang is in your opinion not a good implementation of undefined behavior when running a buggy program, if recursive mutex is used for gfc_unit's lock and a recursion counter is present, then anyone calling gfc_unit could then check the recursion count and if it is bigger than 1, unlock_unit it again and report an error. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=30617

[Bug fortran/30733] New: VOLATILE: Missed optimization - attribute not restricted to scope
+++ This bug was initially created as a clone of Bug #30522 +++ Setting the VOLATILE attribute to a host- or use-associated variable currently marks the variable everywhere as VOLATILE. The attribute should be, however, restricted to the scope. (This is a missed optimization only.) Possible implementation: decl.c: gfc_match_volatile case MATCH_YES: /* If the use- or host-associated symbol is not volatile, we clone it. */ if (!sym-attr.volatile_ sym-ns != gfc_current_ns) { /* note somewhere that in this namespace VOLATILE is needed, e.g. by cloning the variable here and setting below the attribute only to the cloned variable.

Now, if Fortran2003 allows some recursive access to the same unit (under which conditions?) I think the question is settled: recursive access to external units is invalid. then anyone calling gfc_unit could then check the recursion count and if it is bigger than 1, unlock_unit it again and report an error. This seems the path to follow to implement a runtime error, isn't it?

Bytes alignement problem with arm-linux-gcc
Hi all I'm actually working with arm-linux-gcc 3.4.4 and i've noticed a bug when using union. Indeed i've written the following union but sizes doesn't match the reallity: typedef union _t_paquet{ unsigned char msg[14]; struct _NAMEDFIELD{ unsigned char error ; unsigned long entete ; unsigned char len ; unsigned char data[8] ; } NAMEDFIELD; }t_paquet ; Normally we will have the following sizes: sizeof(a.msg) = 14 sizeof(a.NAMEDFIELD.error) = 1 sizeof(a.NAMEDFIELD.entete) = 4 sizeof(a.lNAMEDFIELD.en) = 1 sizeof(a.NAMEDFIELD.data) = 8. So we can think that sizeof(a.msg)=sizeof(a.NAMEDFIELD) but sizeof(a.NAMEDFIELD)=20 ... How can this problem can be resolved? Is there a specific compilation option for alignement problems? With regards Frederic

--- Comment #20 from kargl at gcc dot gnu dot org 2007-02-08 16:18 --- (In reply to comment #17) Now, if Fortran2003 allows some recursive access to the same unit (under which conditions?), Recursive IO to external units is simply not allowed by the Fortran 95 and Fortran 2003 standards. You could wade through Brooks posts in fortran@ to see where recursion is allowed. __gthread_recursive_mutex_t as well as the initializer, perhaps together with adding a recursion count (as the recursion count in __gthread_recursive_mutex_t isn't portably accessible) to gfc_unit as well. The question is how much is libgfortran prepared for changes happening to gfc_unit happening between say st_write and st_write_done calls (st_write normally calls get_unit and thus acquires gfc_unit's lock, which is held until st_write_done calls unlock_unit). This sound like a performance penalty imposed on anyone writing standard conforming code to permit nonconforming code to run. The fact remains that a fortran processor can do anything it wants with nonconforming code. It might work on some architecture and it may fail another for some definition of work and fail. So be it. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=30617

From inside the compiler it can be checked that both alias sets do not conflict. That is important to know, because the rs6000 backend has provisions to generate a sort of schedule barrier instruction supposed to clobber stack memory in order to not resort the saved register instructions with the stack adjustment. That's the 'stack_tie' instruction. That one uses gen_frame_mem() to create a MEM rtx which it can clobber, but that will have (in this case) alias set 4 (get_frame_alias_set() ).

[Bug libgcj/30570] Word DEBUG used as a variable in VMAccessController.java breaks build
--- Comment #3 from rob1weld at aol dot com 2007-02-08 20:56 --- I found out exactly what the trouble is - it _likely_ affects ALL platforms. I use a very long set of configure options (to enable as much as possible) but the one that is causing the trouble is: --enable-libgcj-debug . I proved this by altering the file: gcc-4_2-branch/libjava/java/security/natVMAccessController.cc I added this around the #include config.h statement: static const jint DEBUG = 1L; #include config.h static const jint DEBUG = 1L; I then compiled the file using the exact same command that make shows on screen plus I added -E to show the error and examined the resulting file: # 11 /cygdrive/C/makecygwin/gcc-4_2-branch/libjava/java/security/natVMAccessController.cc static const jint DEBUG = 1L; # 1 ./include/config.h 1 # 14 /cygdrive/C/makecygwin/gcc-4_2-branch/libjava/java/security/natVMAccessController.cc 2 static const jint 1 = 1L; The second 'jint' statement is wrong so that means that the included config.h wrecked things. Looking at file: /gcc-4_2-branch-build/i686-pc-cygwin/libjava/include/config.h we have this: /* include/config.h. Generated by configure. */ /* include/config.h.in. Generated from configure.ac by autoheader. */ /* Define this if you want runtime debugging enabled. */ #define DEBUG 1 Note: We have the same definition (without causing the error, since _this_ config.h is not included) here in /gcc-4_2-branch-build/i686-pc-cygwin/libjava/classpath/include/config.h. /* include/config.h. Generated by configure. */ /* include/config.h.in. Generated from configure.ac by autoheader. */ /* Define to 1 if you want native library runtime debugging code enabled */ #define DEBUG 1 That second one does not cause any trouble but _IF_ you are going to change the word DEBUG be sure to change them both if they should both be the same word. This problem comes from the file: /gcc-4_2-branch/libjava/include/config.h.in so this _IS_ a 'gcc problem' and not a problem with either classpath's source or Cygwin's headers. Here is the part of config.h.in at fault: /* include/config.h.in. Generated from configure.ac by autoheader. */ /* Define to one of `_getb67', `GETB67', `getb67' for Cray-2 and Cray-YMP systems. This function is required for `alloca.c' support on those systems. */ #undef CRAY_STACKSEG_END /* Define to 1 if using `alloca.c'. */ #undef C_ALLOCA /* Define this if you want runtime debugging enabled. */ #undef DEBUG /* Define if system properties shouldn't be read from getenv(GCJ_PROPERTIES). */ #undef DISABLE_GETENV_PROPERTIES Now that _MAY_ seem inocent enough but what happens when you run /gcc-4_2-branch/configure --enable-libgcj-debug is that /gcc-4_2-branch/libjava/configure gets passed the --enable-libgcj-debug and creates a confdefs.h file (that gets deleted - thus hiding the problem from searching). When the /gcc-4_2-branch/libjava/configure script gets near the end it does the sed script routine (to substitute variables in the *.in files) it uses the confdefs.h file as well. Here is the part of the configure script that says it does this: # Transform confdefs.h into two sed scripts, `conftest.defines' and # `conftest.undefs', that substitutes the proper values into # config.h.in to produce config.h. The first handles `#define' # templates, and the second `#undef' templates. That tells me that configure is replacing the #undef DEBUG in config.h.in with #define DEBUG 1 if configure uses the parameter --enable-libgcj-debug. This creates the problem in the java/security/VMAccessController.h file that is made by gcjh (I hope I explained that correctly). I just got through re-running /gcc-4_2-branch/configure (with all my long list of parameters) without using --enable-libgcj-debug and make runs without causing the error (while compiling gcc-4_2-branch/libjava/java/security/natVMAccessController.cc) it still breaks _elsewhere_ ;( . I am not an expert on Java and I will leave it to the experts as how best to fix this. My 2 cents is that the file /gcc-4_2-branch/libjava/configure is wrong since it sets #define DEBUG 1 ; and in doing so it breaks the file java/security/VMAccessController.h (created by gcjh). I suggest that this is _equally_ applicable to _all_ platforms and would halt the build for anyone who uses --enable-libgcj-debug (_AND_ also uses other parameters that cause /gcc-4_2-branch/libjava/java/security/natVMAccessController.cc to be compiled). Since this should happen on any platform can someone else confirm it? (As a point of interest I am using this /gcc-4_2-branch/configure command: /cygdrive/C/makecygwin/gcc-4_2-branch/configure --disable-werror --verbose --target=i686-pc-cygwin --enable-languages=c,ada,c++,fortran,java,objc,obj-c++ --prefix=/usr --exec-prefix=/usr --sysconfdir=/etc --libdir=/usr/lib --libexecdir=/usr/lib --mandir=/usr/share/man --infodir=/usr/share/info --enable-shared --enable-static --enable-nls
[Bug c++/30738] New: suboptimal code for min, max, et al
For T being an arithmetic type, gcc 4.1 generates what looks like suboptimal assembly code for inline C++ functions that take their argument(s) by const reference (const T) vs the same functions that take their argument(s) by value (T). Ideally, the code generated for test_min_ref() and test_min_ptr() below would be the same as for test_min_val().

[Bug ada/30740] New: Improper semantics in gnat's compilation of certain expressions involving modular arithmetic
The problem appears in the evaluation of certain expressions with modular variables. Without the use of the -gnato option during compilation, the executable produced by gnat 3.15p on Solaris for the source code shown below produces incorrect results. Here's a sample output line from this program: __ When J=2, Test_Pattern*2**J =124 or 2#100# but Test_Pattern*2**2 = 60 or 2#00# __ 60 is correct, 124 is incorrect. So the default behavior of the compiler does not appear to match the semantics of the Ada language standard for modular values and the workaround requires use of an option (-gnato) that should not be influencing the behavior of this program. (Overflow is not possible for modular values; they must always wrap around.) See http://groups.google.com/group/comp.lang.ada/browse_thread/thread/4eca860272d4832b/3bca35e8bb0bdb52?hl=en#3bca35e8bb0bdb52 for a complete discussion of this problem. Here's the source code of a program that demonstrates this problem in my environment and, according to others on comp.lang.ada, other environments as well: with Ada.Text_IO; use Ada.Text_IO; procedure Strange_Typing is type Six_Bits is mod 2**6; package Six_Bit_IO is new Ada.Text_IO.Modular_IO(Six_Bits); use Six_Bit_IO; Test_Pattern : Six_Bits := 31; -- 5 bits of ones begin Put(The test pattern is a modulo 2**6 integer = ); Put(Test_Pattern, 0); Put( or ); Put(Test_Pattern, 0, 2); New_Line(2); for J in 0 .. 5 loop Put(When J=); Put(Six_Bits(J), 0); Put(, ); Put(Test_Pattern*2**J =); Six_Bit_IO.Put( Test_Pattern*2**J); Put( or ); Six_Bit_IO.Put( Test_Pattern*2**J, 0, 2); Put(Ascii.Ht but ); case J is when 0 = Put(Test_Pattern*2**0 = ); Put( Test_Pattern*2**0, 0);Put( or ); Put( Test_Pattern*2**0, 0, 2); when 1 = Put(Test_Pattern*2**1 = ); Put( Test_Pattern*2**1, 0);Put( or ); Put( Test_Pattern*2**1, 0, 2); when 2 = Put(Test_Pattern*2**2 = ); Put( Test_Pattern*2**2, 0);Put( or ); Put( Test_Pattern*2**2, 0, 2); when 3 = Put(Test_Pattern*2**3 = ); Put( Test_Pattern*2**3, 0);Put( or ); Put( Test_Pattern*2**3, 0, 2); when 4 = Put(Test_Pattern*2**4 = ); Put( Test_Pattern*2**4, 0);Put( or ); Put( Test_Pattern*2**4, 0, 2); when 5 = Put(Test_Pattern*2**5 = ); Put( Test_Pattern*2**5, 0);Put( or ); Put( Test_Pattern*2**5, 0, 2); end case; New_Line; end loop; New_Line; end Strange_Typing; -- Summary: Improper semantics in gnat's compilation of certain expressions involving modular arithmetic Product: gcc Version: unknown Status: UNCONFIRMED Severity: normal Priority: P3 Component: ada AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: jaffem at erau dot edu http://gcc.gnu.org/bugzilla/show_bug.cgi?id=30740

When you passed it PROG1.C instead of prog1.c, you're telling it to compile a C++ program. Did you install the C++ compiler? Do you get the same error if you use prog1.c instead of PROG1.C ? -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=30741

[Bug libfortran/30498] Support traceback (backtrace) on errors
--- Comment #5 from P dot Schaffnit at access dot rwth-aachen dot de 2007-02-09 07:44 --- Hi! This is great! I cannot judge how much work this would be, but would it be possible to extend this patch a little further so that these backtraces can be requested by the user? (i.e. like the service routines 'ERRTRA' from Lahey, 'TRACEBACKQQ' from Digital|Compaq|HP|Intel or 'Trace_Back_Stack_and_Print' from SGI). This way it can also be used for user error handling... Thanks! Philippe -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=30498
