[Bug middle-end/45567] [4.6 Regression] __builtin_popcountl ICEs with -ftree-ter
--- Comment #2 from fxcoudert at gcc dot gnu dot org 2010-09-10 21:24
---
Confirmed on x86_64-linux, with the following C source:
unsigned foo (__int128 i)
{
return __builtin_popcountl ((unsigned long) i);
}
$ ./gcc/cc1 -ftree-ter a.c -quiet
a.c: In function foo:
a.c:3:30: internal compiler error: in emit_library_call_value_1, at
calls.c:3485
I don't now since how long the code above ICEs, but the revision range given in
the original report is probably not linked to the introduction of the issue,
just to when it became to be exposed by gfortran generating different code for
the POPCNT intrinsic (which was my doing, so I'm glad it's not a Fortran bug
:).
The backtrace for the failure is:

Two more things:
1. there's no need for __int128, the following code also triggers it:
unsigned foo (unsigned char i) { return __builtin_popcountl ((unsigned long)
i); }
2. On x86_64-darwin, the code above fails with -ftree-ter for both: 4.5.1 and
4.6.0 (current trunk).

[Bug target/45476] New: libgcc should contain TFmode functions
As the Fortran front-end now uses soft-float quad precision floating-point
types (__float128 and its complex counterpart), it would be nice for libgcc to
contain TFmode functions on Intel/darwin.
This is present on *86*-{linux,mingw,solaris} and ia64-{linux,hpux}. It was
recently introduced in *86*-freebsd, see patch at
http://gcc.gnu.org/ml/gcc-patches/2010-08/msg02139.html

It partially does. But TC functions are missing:

return 0;

It might be due to the way Tru64 Unix implements toupper. Typically happens because when toupper is a macro that is equivalent to something like: #define toupper(x) (upper_table[x]) POSIX seems to says shall be declared as functions and may also be defined as macros. Does it help to cast the argument to (int)? I mean: -cup = toupper (base_name[dim_i]); +cup = toupper ((int) base_name[dim_i]); for all three toupper? It should. Another solution is to force the function call (but that may mean slower code): cup = (toupper) (base_name[dim_i]); -- fxcoudert at gcc dot gnu dot org changed: What|Removed |Added CC||fxcoudert at gcc dot gnu dot ||org Status|UNCONFIRMED |NEW Ever Confirmed|0 |1 Last reconfirmed|-00-00 00:00:00 |2010-08-23 08:37:12 date|| http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45323

[Bug fortran/44448] 32-bit gfortran.dg/atan2_1.f90 fails on Solaris 1[01]/x86 at -O0
--- Comment #5 from fxcoudert at gcc dot gnu dot org 2010-06-16 21:30

This makes no sense at all. Rainer, I'm really sorry if it seems that I'm
shooting questions a bit at random, but I have a hard time imagining how to
narrow it down.
Can you try the following equivalent C code (at -O0):
#include math.h
#include stdio.h
int main (void)
{
int i;
float x;
double y;
for (i = 1; i = 10; i++)
{
x = __builtin_atan2f (1.f, (float) i / 10.f)
- __builtin_atan2f (1.f, (float) i / 10.f);
printf (%g\n, x);
x = atan2f (1.f, (float) i / 10.f)
- atan2f (1.f, (float) i / 10.f);
printf (%g\n, x);
y = __builtin_atan2 (1., (double) i / 10.)
- __builtin_atan2 (1., (double) i / 10.);
printf (%lg\n, y);
y = atan2 (1., (double) i / 10.)
- atan2 (1., (double) i / 10.);
printf (%lg\n, y);
}
return 0;
}
Right now, the only thing I can see make sense is numerically instability in
the libm. Also, how are atan2f and atan2 defined in the system's math.h header?
Do they have simple prototypes? Are they actually macros?

We maintain a hash table of identifiers, so that when we have multiple times the same string, it's always allocated only once. See how gfc_get_string works, especially the comment at the top: /* Given printf-like arguments, return a stable version of the result string. We already have a working, optimized string hashing table in the form of the identifier table. Reusing this table is likely not to be wasted, since if the function name makes it to the gimple output of the frontend, we'll have to create the identifier anyway. */ The other, extra-nice benefits of these are 1. we do not have to compare strings, but simply pointers; 2. we don't have to worry about releasing memory on a per-case basis.

--- Comment #5 from fxcoudert at gcc dot gnu dot org 2010-05-17 12:53
---
On Mac OS X (all versions), the correct fix is to use _NSGetEnviron() instead
of extern variable environ, and to include crt_externs.h. Example of use:
#include stdlib.h
#include string.h
#include crt_externs.h
int main (void)
{
// Instead of: extern char **environ;
#define environ (*_NSGetEnviron())
char **env = malloc (3 * sizeof(char *));
env[0] = strdup (VAR1=this is variable one);
env[1] = strdup (PATH=/dev/null);
env[2] = NULL;
environ = env;
system (/usr/bin/env);
return 0;
}
(see http://www.gnu.org/software/gnulib/manual/html_node/environ.html)
So, a possible patch (protecting target-specific code with #idef's; I don't
know if that's the style libjava maintainers would like best) is:

[Bug bootstrap/42424] in-tree GMP/MPFR/MPC bootstrap fails
--- Comment #3 from fxcoudert at gcc dot gnu dot org 2010-01-02 19:53
---
OK, I can reproduce the issue.
1. I have a GCC trunk (rev. 155544). In there I put symlinks to gmp-4.3.1,
mpfr-2.4.2 and mpc-0.8.1
2. From an empty build directory, I configure with: ../trunk/configure
--prefix=/Users/fx/devel/gcc/irun --enable-languages=c
3. make fails with:
checking for __gmpz_init in -lgmp... no
configure: error: libgmp not found or uses a different ABI.
make[2]: *** [configure-stage1-mpc] Error 1
make[1]: *** [stage1-bubble] Error 2
make: *** [all] Error 2
The problem is actually not an ABI one, but that the mpc configure fails with:
configure:10805: checking for __gmpz_init in -lgmp
configure:10830: gcc -o conftest -g -fkeep-inline-functions
-I/Users/fx/devel/gcc/ibin-intree/./gmp -I/Users/fx/devel/gcc/trunk/mpfr
conftest.c -lgmp 5
ld: library not found for -lgmp
The problem is that mpc isn't told where to find the gmp and mpfr libraries. It
is confirmed by the mpc configure command-line (from mpc/config.log):
/Users/fx/devel/gcc/trunk/mpc/configure --cache-file=./config.cache
--prefix=/Users/fx/devel/gcc/irun --enable-languages=c
--program-transform-name=s,y,y, --disable-option-checking
--build=x86_64-apple-darwin10.2.0 --host=x86_64-apple-darwin10.2.0

--enable-languages=c --disable-shared
--with-gmp-include=/Users/fx/devel/gcc/ibin-intree/./gmp
--with-mpfr-include=/Users/fx/devel/gcc/trunk/mpfr
This can be contrasted with mpfr, which is configured with
'--with-gmp-build=/Users/fx/devel/gcc/ibin-intree/./gmp', and thus knows where
to find libgmp. So it seems that the following patch should be applied to
configure.ac:

how to deal with that.

I can confirm the segfault at -O3 with current trunk (rev. 155505) on
x86_64-apple-darwin10.2.0. I also generated a (much) reduced testcase:
void K (int *gpwgts, int *badminpwgt, int *badmaxpwgt)
{
int i;
for (i = 0; i 10; i += 2) {
badminpwgt[i] = badminpwgt[i+1] = gpwgts[i]+gpwgts[i];
badmaxpwgt[i] = badmaxpwgt[i+1] = gpwgts[i]+gpwgts[i];
}
}
The segfault backtrace is:

This is not a Fortran issue, but a generic Darwin issue:

$ gcc -c a.c ll a.o

On Linux, for example, we don't get such a large object file as x is put in the
BSS section. Seems like this does not happen on darwin.

[Bug fortran/40812] Files 2GB are incorrectly handled on mingw
--- Comment #5 from fxcoudert at gcc dot gnu dot org 2009-09-05 10:10 --- I can confirm the issue with Steve's testcase on a (i686-darwin) to (i586-pc-mingw32) cross-compiler, at trunk revision 151373. The issue can even be seen while running the compiled program under wine, which should make it rather easy to reproduce without having to deal with Windows :) I even have a simplified testcase, with one big write (and no CPU consumption dealing with integer formating): implicit none character(len=1024*1024), parameter :: mb = integer :: i open(1, file = 't2.dat') write (1,(A)) (mb, i = 1, 2*1024 + 100) close(1) end $ ls -l t2* -rw-r--r-- 1 fx staff 2252343396 Sep 5 12:05 t2-darwin.dat -rw-r--r-- 1 fx staff 2251296966 Sep 5 12:06 t2-mingw.dat where t2-darwin.dat is produced by the darwin executable, and t2.dat is produced by the mingw executable. Please note: the sizes should actually not be equal, but t2-mingw.dat should have exactly 2148 more bytes (= 2*1024 + 100) because mingw has CR+LF line endings. -- fxcoudert at gcc dot gnu dot org changed: What|Removed |Added CC||fxcoudert at gcc dot gnu dot ||org Status|UNCONFIRMED |NEW Ever Confirmed|0 |1 GCC build triplet|Same| GCC host triplet|Windows XP Pro, Core2Quad | |Q6600, 2Gb RAM | GCC target triplet|Same|i586-pc-mingw32 Keywords||wrong-code Known to fail||4.5.0 Last reconfirmed|-00-00 00:00:00 |2009-09-05 10:10:54 date|| Summary|Incorrectly writes/reads|Files 2GB are incorrectly |formatted ASCII files |handled on mingw |greater than 2Gb| http://gcc.gnu.org/bugzilla/show_bug.cgi?id=40812
