[Bug fortran/44773] [4.6 Regression] Unnecessary temporaries increase the runtime for channel.f90 by ~70%
--- Comment #1 from burnus at gcc dot gnu dot org 2010-07-02 07:31 --- At revision 161670, gfortran creates unneeded temporaries (not created up to r161462). (r161462 = PR 44582) channel.f90 has: program sw double precision,dimension(M,N):: f,dudx,dvdy,dhdx,dhdy dudx = ddx(u(:,:,mid)) contains function ddx(array) And the problem is: How should the compiler know that ddx does not use the (host associated) dudx? Note: The function ddx is not declared as PURE - and also cannot simply marked as pure as it host-associates the variables I and J - thus a simple check for no host association would not work. Hence, I fail to see how the compiler can handle it. Unless you find an example where the compiler could know it, I fear one has to close the PR as WONTFIX. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44773

[Bug gcov-profile/44779] New: The gcov library does not adequately handle functions with constructor/destructor attributes
I am developing a software system which has the requirement (as it is safety-critical), that we report full coverage of our modules as part of the validation process. One aspect of this software system is the inclusion of a library - lets call it libguardian - which is wrapped around all applications being run on our custom system, using LD_PRELOAD. The purpose of libguardian is to obtain valid conditions for continued launch prior to the execution of main() by the runtime in the wrapped application. To this end, libguardian defines a constructor and destructor pair of functions that obtain the valid conditions required for continued launch, and clean up/report on exit of the application. This libguardian, and associated applications, works perfectly fine. However, it is not possible to capture coverage information for these functions due to limits in gcov. The constructor/destructor methods are defined thus: #define GUARDIAN_CONSTRUCTOR_DESTRUCTOR_PRIORITY 65535 /* NOTE: this priority can also be 101! */ void guardian_constructor(void) __attribute__ ((constructor(GUARDIAN_CONSTRUCTOR_DESTRUCTOR_PRIORITY))); void guardian_destructor(void) __attribute__ ((destructor(GUARDIAN_CONSTRUCTOR_DESTRUCTOR_PRIORITY))); If the guardian_constructor() finds conditions unsavory for continued execution in our environment, it exit()'s immediately. In this circumstance, coverage is lost (or not provided) by gcov's atexit/destructor methods, as it appears that *priority* of known constructors is not accounted for in the gcov library, nor is there an atexit() handler that can adequately sort these priorities. -- Summary: The gcov library does not adequately handle functions with constructor/destructor attributes Product: gcc Version: 4.1.2 Status: UNCONFIRMED Severity: normal Priority: P3 Component: gcov-profile AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: jay dot vaughan at thalesgroup dot com GCC host triplet: i586-redhat-linux- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44779

[Bug fortran/44773] [4.6 Regression] Unnecessary temporaries increase the runtime for channel.f90 by ~70%
--- Comment #2 from dominiq at lps dot ens dot fr 2010-07-02 08:19 --- And the problem is: How should the compiler know that ddx does not use the (host associated) dudx? Note: The function ddx is not declared as PURE - and also cannot simply marked as pure as it host-associates the variables I and J - thus a simple check for no host association would not work. Hence, I fail to see how the compiler can handle it. Unless you find an example where the compiler could know it, I fear one has to close the PR as WONTFIX. (1) Please refrain to close this pr. (2) I'll have a closer look to what's happening at the inlining level (i.e., before revision 161550 the functions ddx and ddy were inlined. I don't know if it is still the case). (3) The body of ddx does not use dudx or dhdx (ddy does not use dydy or dhdy) and u,v, and h don't allias with dudx, ..., so it is not difficult for the user to check that there is no need for temporaries. Why should it be impossible for the compiler? -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44773

--- Comment #3 from mikael at gcc dot gnu dot org 2010-07-02 08:45 --- It could be useful at several places to have a function traversing the code of a procedure and telling whether an array is read or written to by that procedure. It should be quite doable for the write case (only assignments and procedure calls to care about). For the read case, however, it could take some time to get it right, as every statement has its own parameters with its own restrictions and assumptions. This is pure speculation anyway. By the way, what is the complete (or reduced) test case ? -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44773

[Bug c/44774] -Werror=edantic
--- Comment #7 from manu at gcc dot gnu dot org 2010-07-02 10:56 --- Why? All of them do, except -pedantic. I don't see any reason for -pedantic being exceptional. Or can I start proposing warnings options that do not start with -W? Should we introduce a special case for pedantic (code and documentation) for -Werror= and for -Wno-error= and for -Wno-? I can start opening PRs for the missing special cases. We would also need to introduce (and handle specially) -no-pedantic and -no-pedantic-errors. All the above is free if we just make -Wpedantic an alias for -pedantic. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44774

[Bug c++/44786] New: -fcatch-undefined-behavior: Turn on runtime code generation to check for undefined behavior
Clang provides a number of ways to control code generation. The options are listed below. -fcatch-undefined-behavior: Turn on runtime code generation to check for undefined behavior. This option, which defaults to off, controls whether or not Clang adds runtime checks for undefined runtime behavior. If the check fails, __builtin_trap() is used to indicate failure. The checks are: # Subscripting where the static type of one operand is variable which is decayed from an array type and the other operand is greater than the size of the array or less than zero. # Shift operators where the amount shifted is greater or equal to the promoted bit-width of the left-hand-side or less than zero. # If control flow reaches __builtin_unreachable. -- Summary: -fcatch-undefined-behavior: Turn on runtime code generation to check for undefined behavior Product: gcc Version: unknown Status: UNCONFIRMED Severity: enhancement Priority: P3 Component: c++ AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: manu at gcc dot gnu dot org http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44786
[Bug fortran/44773] [4.6 Regression] Unnecessary temporaries increase the runtime for channel.f90 by ~70%
--- Comment #6 from dominiq at lps dot ens dot fr 2010-07-02 16:53 --- Yes, please reduce and lets see if we can discover something more specific wrong here. Then also consider Mikael's idea. I don't think there is anything specific to discover. The fix for PR44582 is too conservative and creates unneeded temporaries (in channel.f90, test_fpu.f90 and probably others that I have missed). I'll be extremely sad that to fix (ab)uses of the standard (codes you should never write), legitimate real life codes get badly penalized. You can also see the effect at http://gcc.opensuse.org/c++bench/polyhedron/polyhedron-summary.txt-2-0.html where the time went from ~16.5s to ~18.7s. The relative effect is less dramatic because channel.f90 is memory bound for caches smaller than ~4Mb: I don't know the cache size of the AMD proc for the above test (~512kb?) compared to the 3Mb on my macbook. So the effect of the new temporaries is to increase the memory access by ~2s, i.e., ~10% on the AMD tests, but ~70% on my machine. So I doubt that a reduced test wil give any new insight in the problem, nevertheless I'll try!-). -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44773

The patch optimizes the prologue part only, the epilogue can also be enhanced.
Now compile the attached test case, I get

add r0, sp, #4

add sp, sp, #12

[Bug middle-end/44790] New: Bootstrap fails after MEM-REF merge
GCC fails to bootstrap on ia64-hp-hpux11.23 after r161655. Building without
bootstrap and running the testsuite shows that tests are failing in 32 bit mode
but not 64 bit mode so the problem is probably ia64's unique method of
extending pointers in 32 bit mode Most of the failing tests involve va_args.
Here is a cutdown test that fails:
f (int n, ...)
{
long x;
int i;
__builtin_va_list ap;
__builtin_va_start(ap,n);
x = __builtin_va_arg(ap,long);
if (x != 123)
abort();
__builtin_va_end(ap);
}
main ()
{
f (3, (long) 123);
exit(0);
}
