Perhaps it would be also good to add new peephole2 to catch:
(insn 931 415 932 33 (set (reg:CC 19 r19)
(mem/c:CC (plus:DI (reg/f:DI 1 r1)
(const_int 272 [0x110])) [5 %sfp+272 S4 A32])) where_2.f90:11
358 {*movcc_internal1}
(nil))
(insn 932 931 461 33 (set (reg:CC 74 cr6)
(reg:CC 19 r19)) where_2.f90:11 358 {*movcc_internal1}
(expr_list:REG_DEAD (reg:CC 19 r19)
(nil)))
(insn 461 932 422 33 (set (reg:SI 27 r27 [712])
(gt:SI (reg:CC 74 cr6)
(const_int 0 [0]))) where_2.f90:11 462 {*rs6000.md:13486}
(expr_list:REG_DEAD (reg:CC 74 cr6)
(nil)))
which is expanded to (if -fno-schedule-insns2, but peephole2 is run before
second scheduling):
lwz r19,272(r1)
rlwinm r19,r19,8,0x
mtcrf 2,r19
rlwinm r19,r19,24,0x
mfcr r27
rlwinm r27,r27,26,1
while only one lwz and one rlwinm are actually needed (BTW, also it would be
nice to avoid the second rlwinm in movcc_internal1 pattern if the source
integer register is dead at the insn).
I guess this can happen quite often, any time the register pressure is too high
and reload spills CC mode registers and then they are used just once for cr*
cond 0 ? 1 : 0 assignments.
[Bug fortran/46846] New: Warning of AINT as actual argument ain't right
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=46846 Summary: Warning of AINT as actual argument ain't right Product: gcc Version: 4.6.0 Status: UNCONFIRMED Keywords: diagnostic, documentation, wrong-code Severity: normal Priority: P3 Component: fortran AssignedTo: unassig...@gcc.gnu.org ReportedBy: bur...@gcc.gnu.org http://groups.google.com/group/comp.lang.fortran/browse_thread/thread/8ac296b9404b3245 lnblnk is a GNU extension. char, ichar, int, and len_trim are also rejected by other compilers. Currently, gfortran prints the warning Warning: Interface mismatch in dummy procedure 'fun' at (1): '%s' has the wrong number of arguments for the intrinsics aint, anint, index, len and nint. 13.6 Specific names for standard intrinsic functions Speci c NameGeneric Name ArgumentType and Kind AINT AINT default real ANINT ANINTdefault real INDEX INDEXdefault character LENLEN default character NINT NINT default real The problem is that all those functions have an optional KIND= argument - which, however, is not included in the specific functions (as backward compatibility to Fortran 77). Thus, the warning is bogus - but another question is whether this can lead to wrong code by not passing NULL as second argument. I have not checked, but maybe the documentation should also be improved (cf. James' posting to c.l.f)
[Bug other/46847] New: Missed optimization for variant of Duff's device
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=46847 Summary: Missed optimization for variant of Duff's device Product: gcc Version: 4.3.2 Status: UNCONFIRMED Severity: normal Priority: P3 Component: other AssignedTo: unassig...@gcc.gnu.org ReportedBy: j...@acm.org The attached file contains a function that implements a variant of Duff's device to zero out part of an array. GCC 4.3.2 (Red Hat 4.3.2-7) with -O3 generates rather bad code for x86-64; the code it produces for i386 might also be improved. Generated code for -m32 and -m64 is in the attached file. The -m64 version contains multiple copies of a redundant load for %esi (and corresponding jumps). Both versions move the computation of 'end' inside the loop, which seems unnecessary to me.

I did various configure runs with various options, and TARGET_CONFIGDIRS appeared to generally include libffi when appropriate and not include it when appropriate. What configure options are you using? I am using --enable-languages=c,c++,objc,fortran,obj-c++,java,ada --disable-libgcj which formerly disabled building of libffi, but now leaves it enabled (even if go is not enabled). I didn't remember that, so maybe the issue isn't that important. But maybe we can have a --disable-libffi configure option? (continuing to disable libffi with --disable-libgcj if Go is not build would be also ok of course). Richard.

The problem is that REG_EQUAL note on insn 107 isn't adjusted and then with
high register pressure just results in wrong code.

UTC ---
I stumbled into the underlying cause of this bug while working on
dllimport/dllexport attributes. It turns out that the TARGET_INSERT_ATTRIBUTES
hook is broken in C++, because of a bit of premature optimisation in the
routine gcc/cp/decl2.c#cplus_decl_attributes(). This is a C++-specific wrapper
round the core compiler's gcc/attribs.c#decl_attributes() which takes care of
deferred attribute handling for templates:
/* Like decl_attributes, but handle C++ complexity. */
void
cplus_decl_attributes (tree *decl, tree attributes, int flags)
{
if (*decl == NULL_TREE || *decl == void_type_node
|| *decl == error_mark_node
|| attributes == NULL_TREE)
return;
if (processing_template_decl)
{
if (check_for_bare_parameter_packs (attributes))
return;
save_template_attributes (attributes, decl);
if (attributes == NULL_TREE)
return;
}
if (TREE_CODE (*decl) == TEMPLATE_DECL)
decl = DECL_TEMPLATE_RESULT (*decl);
decl_attributes (decl, attributes, flags);
if (TREE_CODE (*decl) == TYPE_DECL)
SET_IDENTIFIER_TYPE_VALUE (DECL_NAME (*decl), TREE_TYPE (*decl));
}
The early exits when attributes == NULL_TREE are (I suppose) intended to save
the time taken calling decl_attributes when there aren't any attributes to be
added to the newly-created decl, but it has the side-effect of bypassing the
call that decl_attributes makes to TARGET_INSERT_ATTRIBUTES. The consequence
is that the default/target/pragma-derived attributes don't get inserted onto
any decls in C++ - except for decls that have some explicit attributes
specified!
I'm going to be testing this fix as part of a larger patch over the next
couple of days, perhaps others would like to give it a try on their platforms:

[Bug c/19541] need another option to support what -I- did just besides -iquote
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=19541 --- Comment #19 from Chris Litchfield chris.litchfield at gmail dot com 2010-12-08 16:10:47 UTC --- For now, we keep the -iquote in and hope the other parts are not removed. In our shop we have many different functions to try and mitigate the problem. Include files have #defines at the top to prevent the includes from being double included, use the proper syntax of #include and #include when appropriate. Hard coding the include path is just horrible for coding and deemed unacceptable for us. One of the workarounds is drastic but involves configuration management to the extreme. All source files and include files in the same directory and to verify that NO include files are ever duplicated. This can be done and use virtual designs for your projects in IDEs. Redesign of the Include files so they do not pull in other include files or have a layer of include files that include other files but when you change the sub-include files, it automatically pulls in the above layer include file. Yes, all these are ugly for something that should be part of ANY include system. There is a reason an Include Path exists, and to use shortcuts as standard practice inside the compiler hurts everyone here complaining about it. Quite a few developers just continue to use older compiler versions as no need to upgrade into some of the pain. Wish we could assign this to someone. I bet we could keep the needed option as a separate option (-I-). Dont know what this was last reconfirmed 2006 though... Chris (In reply to comment #18) So there is no hope for this option then ?

[Bug c/46853] New: gcc fails to warn about uninitialized variable
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=46853
Summary: gcc fails to warn about uninitialized variable
Product: gcc
Version: 4.4.5
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: gcc-b...@nospam.pz.podzone.net
With the code below gcc warns of uninitialised variable only when not nested in
a loop.
The test case is simple enough. I think gcc should be able to check for this.
The 'FOR_LOOP' test case has also been checked with GNU C (GCC) version 4.4.3
(arm-unknown-elf), and gcc (Debian 4.4.5-8) 4.4.5, with the same behaviour as
below.
$ cat gcc_test.c
int func(void);
int main(void)
{
int foo;
foo = func();
return foo;
}
int func(void)
{
int foo;
#if defined (FOR_LOOP)
int i;
for (i = 0; i 5; i++)
#elif defined (WHILE_LOOP)
while(1)
#endif
{
if (foo == 0x00)/* uninitialised use */
{
foo = 0xFF;
}
}
return foo;
}
$ gcc gcc_test.c -Os -Wall -Wextra -Wuninitialized
gcc_test.c: In function `func':
gcc_test.c:29: warning: `foo' is used uninitialized in this function
$ gcc gcc_test.c -Os -Wall -Wextra -Wuninitialized -DFOR_LOOP
$ gcc gcc_test.c -Os -Wall -Wextra -Wuninitialized -DWHILE_LOOP
$ gcc --version

I have noticed gcc 4.4.5 often produces less optimzed code
than the old 3.4.6. Below is the latest example. I am
starting to wonder if I need rebuild gcc 4.4.5 and/or
add new options to gcc when I compile. Any insight?
