[Bug fortran/45715] [ABI cleanup] Move runtime parsing of I/O control list to front end
--- Comment #2 from burnus at gcc dot gnu dot org 2010-09-21 06:54 --- (In reply to comment #1) Here is a case where we do have to evaluate at run time. So maybe we can not do what is proposed above. Well, I understood the request such that one passes a boolean for the 'YES' / 'NO' items. If it cannot be simplified at compile time, one adds (in trans*c) code like: advance = _gfortran_compare_string (3, YES, len, str) == 0; Possibly, one should add a new function like advance = _gfortran_io_yes_no (len, str, ADVANCE); which takes then also into account invalid values. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45715

[Bug fortran/45710] WRITE of NAMELIST group to internal file contains newline characters
--- Comment #8 from urbanjost at comcast dot net 2010-09-21 09:34 --- Subject: Re: WRITE of NAMELIST group to internal file contains newline characters Per some discussions today, there were apparently different versions on some of the nodes I was using, ranging from 4.3.4 to 4.6.0 (they were all supposed to be identical); so I can't be sure till I get back. But I installed Cygwin on an MSWindows laptop and upgraded to gfortran 4.6.0 (per the gfortran -v switch; it comes with gfortran 4.3.4) and I am getting what you show, which is much better, I looked thru all the 2009 and 2010 fixes and missed seeing any change like this. Maybe a few tweeks are in order? Looking at the f2008 draft standard, from 10.11.4.3 line 5, taken literally the should be in column 2 instead of 1; and the records written to in the OUT array should be blank filled to the end per 9.4 line 2 bullet (d)? That would be more in line with how list-directed output works (column 1 always being clear) and would prevent garbage from being in the lines written to if OUT is not initialized to all blanks; so I think I'm reading (interpreting?) the sections correctly. From the draft: 10.11.4.3Namelist output records 1 If two or more successive values for the same namelist group item in an output record produced have identical values, the processor has the option of producing a repeated constant of the form r *c instead of the sequence of identical values. 2 The name of each namelist group object list item is placed in the output record followed by an equals and a list of values of the namelist group object list item. 3 An ampersand character followed immediately by a namelistgroupname will be produced by namelist formatting at the start of the first output record to indicate which particular group of data objects is being output. A slash is produced by namelist formatting to indicate the end of the namelist formatting. 4 A null value is not produced by namelist formatting. 5 Except for new records created by explicit formatting within a defined output procedure or by continuation of delimited character sequences, each output record begins with a blank character. 9.4 Internal files 1 Internal files provide a means of transferring and converting data from internal storage to internal storage. 2 An internal file is a record file with the following properties. (a)· The file is a variable of default, ASCII, or ISO 10646 character that is not an array section with a vector subscript. (b)· A record of an internal file is a scalar character variable. (c)· If the file is a scalar character variable, it consists of a single record whose length is the same as the length of the scalar character variable. If the file is a character array, it is treated as a sequence of character array elements. Each array element, if any, is a record of the file. The ordering of the records of the file is the same as the ordering of the array elements in the array (6.5.3.2) or the array section (6.5.3.3). Every record of the file has the same length, which is the length of an array element in the array. (d)· A record of the internal file becomes defined by writing the record. If the number of characters written in a record is less than the length of the record, the remaining portion of the record is filled with blanks. The number of characters to be written shall not exceed the length of the record. (e)· A record may be read only if the record is defined. (f)· A record of an internal file may become defined (or undefined) by means other than an output statement. For example, the character variable may become defined by a character assignment statement. (g)· An internal file is always positioned at the beginning of the first record prior to data transfer, except for child data transfer statements (9.6.4.7). This record becomes the current record. (h)· The initial value of a connection mode (9.5.2) is the value that would be implied by an initial OPEN statement without the corresponding keyword. (i)· Reading and writing records shall be accomplished only by sequential access formatted input/output statements. (j)· An internal file shall not be specified as the unit in a file connection statement or a file positioning statement. - Original Message - From: jvdelisle at gcc dot gnu dot org gcc-bugzi...@gcc.gnu.org To: urbanj...@comcast.net Sent: Monday, September 20, 2010 11:20 PM Subject: [Bug fortran/45710] WRITE of NAMELIST group to internal file contains newline characters --- Comment #7 from jvdelisle at gcc dot gnu dot org 2010-09-21 03:20 --- With current trunk, gfortran 4.6, I get: BEFORE: 001 @@@ 002 @@@ 003

[Bug tree-optimization/45734] [4.6 Regression] Devirtualization results in wrong-code
--- Comment #3 from rguenth at gcc dot gnu dot org 2010-09-21 10:12 ---
The following is miscompiled since ever (and also ICC miscompiles it), so
I'm not sure if it is valid to use 'f' to refer to the Bar object.
namespace std {
typedef __SIZE_TYPE__ size_t;
}
inline void* operator new(std::size_t, void* __p) throw() {
return __p;
}
extern C void abort (void);
class Foo {
public:
virtual void test (void) { abort (); }
};
class Bar : public Foo {
public:
virtual void test (void) { }
};
int main()
{
Foo f;
new (f) Bar();
f.test();
return 0;
}
A variant with using a pointer of type Bar * like
int main()
{
Foo f;
static_castFoo *(new (f) Bar())-test();
return 0;
}
only breaks on recent trunk.
int main()
{
Foo f;
new (f) Bar();
(f)-test();
return 0;
}
also breaks always. While
int main()
{
Foo f, *p;
p = new (f) Bar();
p-test();
return 0;
}
works.
int main()
{
Foo f, *p;
new (f) Bar();
((Foo *)(void *)f)-test();
return 0;
}
also works.
Fun.

[Bug middle-end/45739] New: [missed optimization] static evaluation of SSE intrinsics (pxor)
Testcase:
#include emmintrin.h
__m128i foo;
int main()
{
foo = _mm_xor_si128(_mm_setzero_si128(), foo);
return 0;
}
Resulting Assembly (with -O3):
pxor%xmm0, %xmm0
xorl%eax, %eax
pxorfoo(%rip), %xmm0
movdqa %xmm0, foo(%rip)
ret
Expected Result:
since any value xor zero does not change the value the static evaluation step
of GCC should eliminate the pxor instruction altogether.
Likewise the call to _mm_xor_si128 on two constants should be statically
evaluated and if the destination register would not change the call should be
eliminated.
Rationale:
a) of course removing unnecessary code is always nice
b) the implementation of correct unsigned integer compare can be done with pxor
and 0x8000. All unsigned compares against constant values can thus be
improved.

--- Comment #10 from burnus at gcc dot gnu dot org 2010-09-21 13:52 --- (In reply to comment #9) procedure(), pointer :: ptr3 = p2 I now believe that this is invalid (all quotes are F2008): R505 initialization is [...] or = initial-data-target R443 initial-data-target is designator C461 (R443) The designator shall designate a nonallocatable variable that has the TARGET and SAVE attributes and does not have a vector subscript. Every subscript, section subscript, substring starting point, and substring ending point in designator shall be a constant expression. Well, in the example (cf. also the ICE in comment 5) p2 is a POINTER and a pointer cannot have the TARGET attribute (cf. C556). Thus, the initial-data-target can neither be a pointer nor a proc-pointer. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45290

--- Comment #30 from paolo dot carlini at oracle dot com 2010-09-21 17:55 --- More correctly (in the meanwhile went through a exchange at the beginning of this year), Howard stores the hash, which boils down to a memory requirement similar to that of the traditional doubly linked list scheme per Dinkum in the limit of high load factor, for small load factor is better because can use only one pointer instead of two for each bucket in the bucket list. All in all, if the requirements of throwing hash + erase complexity are combined, I don't think anything with a memory use similar to that of the singly linked schemes is possible. Joaquin, I think Matt would be in favor of a motion asking a re-opening of the issue in Batavia, what do you think? -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41975

--- Comment #3 from ebotcazou at gcc dot gnu dot org 2010-09-21 21:45 --- Java is severely broken on sparc64-linux with gcc 4.5/4.6, which is a major regression from 4.4: http://gcc.gnu.org/ml/gcc-testresults/2010-05/msg00853.html (4.6 broken) http://gcc.gnu.org/ml/gcc-testresults/2010-05/msg00681.html (4.5 broken) http://gcc.gnu.org/ml/gcc-testresults/2010-05/msg00472.html (4.4 works) The detailed test suite logs show that _every_ -findirect-dispatch test case SEGFAULTs shortly after startup. I've bisected trunk and identified r155622 as the cause: Author: jakub Date: Mon Jan 4 16:02:41 2010 New Revision: 155622 URL: http://gcc.gnu.org/viewcvs?root=gccview=revrev=155622 Log: PR driver/42442 * gcc.c (SWITCH_IGNORE_PERMANENTLY): Define. (do_self_spec): For switches with SWITCH_IGNORE set set also SWITCH_IGNORE_PERMANENTLY. (check_live_switch): Check SWITCH_IGNORE_PERMANENTLY instead of SWITCH_IGNORE. [...] The main difference is that in the working compiler, the java classes are assembled with -K PIC but the generated main() is not, while in the broken compiler both the java classes and the generated main() are assembled with -K PIC. Thanks for the detailed analysis. I note that gcc/java/jvspec.c has %findirect-dispatch, and that PR42442 is about correcting the handling of %match=native. Clearly something here doesn't mix well. My interpretation is that the %findirect-dispatch for cc1 used to cancel the effect of -findirect-dispatch for subsequent programs invoked by the driver, in particular 'as' in this case. Jakub's change disables this cancellation so -findirect-dispatch is passed to 'as' and thus the kludge I put in ASM_SPEC for Linux triggers, which breaks because cc1 hasn't compiled the file in PIC mode. -- ebotcazou at gcc dot gnu dot org changed: What|Removed |Added Last reconfirmed|2010-09-20 21:40:00 |2010-09-21 21:45:21 date|| http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44095
