08:35:15 UTC ---
Caused by http://gcc.gnu.org/viewcvs?root=gccview=revrev=145256
The problem is that a COMPOUND_LITERAL_EXPR doesn't have CONSTRUCTOR as its
DECL_INITIAL. Either this is a FE bug (tree.def says that it should be
CONSTRUCTOR), or we should just tweak optimize_compound_literals_in_ctor not to
recurse if TREE_CODE (init) is not CONSTRUCTOR.
Correct source would be
struct bla{char **a;};void test(void){struct bla b = {.a =(char*[]){a,b}};}
[Bug target/52990] bootstrap ia64 cross-compiler gcc (static C-only) includes a broken libgcc.a due to libunwind dependencies

It tries to build a number of utilities and link them against libgcc with the missing symbols that you mentioned. In the scripts that I use to build the toolchains, I was able to solve this by adding a configparms file to the build directory that sets build-programs = no. After the final gcc is built, libunwind is properly installed and can at least be used for dynamically linked executables. I've also tested that the resulting gcc can link static executables, though I'm not able to execute because I lack the hardware.

Note the missed jump threading opportunities from the case decision tree to
the tail calls.
The RTL for one of the missed tail calls looks like this:
...
# BLOCK 11 freq:157 seq:9
# PRED: 10 [50.0%] (FALLTHRU)
# SUCC: 25 [100.0%]
# 145 pc=L144
jmp .L17# 145 jump[length = 2]
...
# BLOCK 25 freq:909 seq:23
# PRED: 11 [100.0%]
.L17:
# SUCC: EXIT [100.0%] (ABNORMAL,SIBCALL)
# 79 call ...
# REG_DEAD: di:SI
jmp use13 # 79*sibcall[length = 5]
I am guessing that jumps to calls are not handled as jump threading
opportunities because the call_insn isn't recognized as just a jump.

[Bug rtl-optimization/54365] New: ARM optimization bug when pointer arithmetic wraps
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=54365
Bug #: 54365
Summary: ARM optimization bug when pointer arithmetic wraps
Classification: Unclassified
Product: gcc
Version: 4.6.3
Status: UNCONFIRMED
Severity: major
Priority: P3
Component: rtl-optimization
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: g...@undo-software.com
Created attachment 28077
-- http://gcc.gnu.org/bugzilla/attachment.cgi?id=28077
Simple program showing the bug.
Apologies if I've got the wrong component - it was a bit of a guess!
The attached program shows a fairly simple, but I think nasty, bug in GCC on
ARM. It seems to be present on at least versions 4.4.5, 4.5.1 and 4.6.3. If
compiled without optimisation, it behaves as I expect: adding 4 to a pointer
such that it wraps gives a pointer that is less than the original. With -O2,
that is not the case. I note that the problem does not occur if I use integer
types.
Transcript follows (.c file attached separately and in transcript below for
convenience):
$ cat compilerbug.c
#include stdio.h
int
main( void)
{
unsigned char* addr = (unsigned char*)0xfffe;
unsigned len = 4;
if ( addr+len addr)
{
printf( it wraps\n);
}
else
{
printf( no wrap\n);
}
return 0;
}

Product: gcc
Version: 4.8.0

This simple code causes an internal error:
char *string = 1;

This is the result of my compiling attempt:

[Bug fortran/25708] Module loading is not good at all
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=25708 Joost VandeVondele Joost.VandeVondele at mat dot ethz.ch changed: What|Removed |Added Depends on||40958 --- Comment #21 from Joost VandeVondele Joost.VandeVondele at mat dot ethz.ch 2012-08-24 14:00:40 UTC --- I did another timing experiment on compiling CP2K. I found that on my server, compiling with -fsyntax-only is as fast as just compiling at -O0. I believe the reason for this is that module reading is dominating the compile time. In CP2K each module is included only once per file, so I think it is the efficiency of reading the module that matters most. My guess would be that the human readable format of the .mod file is the source of most inefficiency. Is it still important to the development of gfortran that the .mod file is in this form ? If I count the number of times a module is used, and multiply that with the size, I have about 1Gb of .mod files being parsed per CP2K compile (for about 35Mb of Fortran).

Still, even though it's undefined, it's slightly strange behaviour for the compiler to adopt.

[Bug target/28896] -fstack-limit-symbol and m68k and non 68020
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=28896 --- Comment #19 from Larry Baker baker at usgs dot gov 2012-08-25 00:28:56 UTC --- I plan to start testing my patches on a ColdFire uClinux system on Monday. In the mean time, I am unsure whether my code is correct for the -fPIC -mno-sep-data case. I do not know if a5 is a volatile register, or if, instead, it must be saved/restored. It is possible (as shown by my example) that a5 might otherwise not be needed by the code in a procedure. In that case, my code is not enabling the save/restore of a5, which would be wrong if a5 is not volatile. This is not a problem for -msep-data (implies -fPIC), since a5 already has the correct value, and is not altered by my code. I will investigate whether a5 is volatile. If anyone knows the answer already, please add a comment. If anyone can recommend what has to be called or modified to force a5 to be saved/restored, I would appreciate hearing about that as well. Thank you, Larry Baker
