[Bug debug/24400] New: x86_64 has incorrect file numbers in dwarf2 .debug_macinfo section
The filenumbers in the .debug_macinfo is wrong. They jump from 0xf to 0x11,
skipping 0x10, so the last filename has a number which isn't in the filename
table. This causes gdb to crash in the lookup table (see
http://sources.redhat.com/cgi-bin/gnatsweb.pl?cmd=view&pr=2009 )
It's easy to see if you compile the following program with "gcc -o helloworld
-g3 -gdwarf-2 -fverbose-asm -dA -save-temps helloworld.c" on x86-64:
#include
int
main ()
{
printf ("hello world\n");
return 0;
}
And then do an "egrep '(\.file|just\ star)' helloworld.s" I see:
...
.file 15 "/usr/lib/gcc/x86_64-linux-gnu/4.0.2/include/stdarg.h"
.uleb128 0xf# Filename we just started
.file 16 "/usr/include/bits/stdio_lim.h"
.uleb128 0x11 # Filename we just started
...
If I compile the same thing with -m32, the output is correct:
...
.file 15 "/usr/lib/gcc/x86_64-linux-gnu/4.0.2/include/stdarg.h"
.uleb128 0xf# Filename we just started

[Bug driver/22544] [4.0/4.1 Regression] gcc ignores input file given on the command line
--- Comment #7 from indan at nul dot nu 2005-10-16 12:06 ---
Was the non-standard behaviour in 3.4 a bug or a feature? In any case, isn't it
reasonable to mention the -combine option in the error message? Something like:
fatal ("cannot specify -o with -c or -S with multiple files. Try -combine");
I don't have the gcc code, but you check for have_c && have_o, but can have_o
ever be true for -S?

The behavior in 3.4 was a feature, IIRC not well documented one.

Well what happens when you do:
gcc -combine t.cc t.c -c -o t.o
We need an error but what should it be. I think leaving out the -combine will
not confuse
people as they should be reading the documention anyways.

have_c is set for both -S and -c.

Yes, they should, still i'd prefer that a hint to -combine is emitted (see
attached fix22544.diff2.txt)
Also your patch had odd whitespace.

[Bug rtl-optimization/19097] [3.4/4.0/4.1 regression] Quadratic behavior with many sets for the same register in gcse CPROP
--- Comment #17 from steven at gcc dot gnu dot org 2005-10-16 23:20 ---
On AMD64, I now get the following timings:
-O1 -O2
3.3 (profilebootstrapped) 46.64 46.90
4.1 (checking=release) 72.82 156.43
In 4.1, the Big Spenders are "dominance frontiers" (41% usr)
and "tree operand scan" (also 41%) for -O1. For -O2 those two
also are big time black holes, and the 3 gcse.c CPROP passes
join them at the top of the profile ("dominance frontiers" 18%,
"tree operand scan" 18%, "CPROP 1" 17%, "CPROP 2" 9%, "bypass
jumps" 10%).
So this is still a regression from GCC 3.3.

[Bug rtl-optimization/17356] [4.0/4.1 Regression] [Ada] [ia64] ACATS c41325a & other ICE, also while building libada
--- Comment #15 from wilson at gcc dot gnu dot org 2005-10-17 02:00 ---
It is dying in rest_of_handle_flow2 -> split_all_insns -> verify_flow_info. We
have non-call insns with EDGE_ABNORMAL_CALL edges attached to them.
The insns are coming from post-reload call insn splits. Before splitting, we
have
(call_insn 118 116 3807 4 (parallel [
(set (reg:OI 8 r8)
(call (mem:DI (symbol_ref:DI
("ada__text_io__editing__parse_num\ber_string") [flags 0x3] ) [0 S8 A64])
(const_int 1 [0x1])))
(clobber (reg:DI 320 b0))
(clobber (scratch:DI))
(clobber (scratch:DI))
]) 257 {call_value_gp} (insn_list:REG_DEP_TRUE 117 (nil))
(expr_list:REG_EH_REGION (const_int 1 [0x1])
(nil))
(expr_list:REG_DEP_TRUE (use (reg:DI 1 r1))
(expr_list:REG_DEP_TRUE (use (reg:TI 120 out0 [ D.1574 ]))
(nil
after splitting we have
(call_insn 4891 116 4892 4 (parallel [
(set (reg:OI 8 r8)
(call (mem:DI (symbol_ref:DI
("ada__text_io__editing__parse_num\ber_string") [flags 0x3] ) [0 S8 A64])
(const_int 0 [0x0])))
(clobber (reg:DI 320 b0))
]) 254 {call_value_nogp} (nil)
(expr_list:REG_EH_REGION (const_int 1 [0x1])
(nil))
(expr_list:REG_DEP_TRUE (use (reg:DI 1 r1))
(expr_list:REG_DEP_TRUE (use (reg:TI 120 out0 [ D.1574 ]))
(nil
(insn 4892 4891 4893 4 (set (reg:DI 1 r1)
(plus:DI (reg/f:DI 111 loc79)
(const_int -80 [0xffb0]))) 105 {adddi3} (nil)
(nil))
(insn 4893 4892 3807 4 (set (reg:DI 1 r1)
(mem:DI (reg:DI 1 r1) [0 S8 A64])) 5 {*movdi_internal} (nil)
(expr_list:REG_EH_REGION (const_int 1 [0x1])
(nil)))
We call find_bb_boundaries to split this into two blocks, and then
purge_dead_edges should delete the abnormal call edge on the load.
But there is a problem here... Ada sets flag_non_call_exceptions by default.
So the load is a trapping insn, just not a call-trapping insn.
In purge_dead_edges, we first verify that an EH edge is OK, then we verify that
an abnormal call edge is OK. But since an abnormal call edge is always an EH
edge, the first test triggers, and passes, because we do need an EH edge here.
We can fix this problem by switching the order of the tests.
With this patch, a cross-compiler ada build got all of the way to gnattools,
where it died building make.adb. This means libada built successfully. The
make.adb error is a different unrelated problem.

I am assuming this is good enough to close the problem after a proper bootstrap
test. I'll have to try a native ia64 bootstrap now.

[Bug c++/20681] [4.0/4.1 Regression] wrong "control reaches" warning with switches
--- Comment #11 from ian at airs dot com 2005-10-17 04:39 --- For the record, this is the work-around in the C frontend: http://gcc.gnu.org/ml/gcc-patches/2005-01/msg01452.html A corresponding patch in the C++ frontend would be more complicated, in order to continue to emit the error "break statement not within loop or switch" when required. This class of bugs is a pain to work with at present. The warning just follows the CFG, which makes sense. But code like case 1: return; break; builds a CFG which has a return followed by a goto. remove_useless_stmts is currently not clever enough to remove code after a return, so the goto gets incorporated into the CFG. Note that we don't get the warning when optimizing; we only get it with -O0. And indeed when not optimizing the assembly code has the code path which returns an uninitialized value, although of course it never gets executed in practice. Fixing this in the middle-end will require a version of remove_useless_stmts which is clever enough to efficiently discard statements which follow a return statement. Andrew was working on that at one point; I don't recall what the status is. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=20681

The problem is also comes into play with extra unreachable labels which was not going to be fixed by my patch and is what really causes this bug, rather than the stuff after a goto/return. We lower the eh before removing the unreachable label which causes us to think that there is a way to get fallthrough the switch. This means that we need a switch table for cleanup of the variable (the call to the dtor). -- Pinski -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=20681

main.c:62: error: storage size of `tape_hdr' isn't known
make: *** [main.o] Error 1
If I uncomment the bottom two size_t's it works. I tried to look into this and
somewhere I found that this is a GCC problem ??? I am not so sure about that,
but can someone please tell me what I am doing wrong ?
struct tape_header
{
char ident [6]; // flows
char label [128]; // Tape Label
char last_bar_code [128]; // last known bar code
size_t bytes_used; // Bytes written to tape
size_t block_size; // Block size at what tape was
format
size_t last_block_used; // Where did we stop
};
gcc -v

--- Comment #1 from pinskia at gcc dot gnu dot org 2005-10-17 06:11 --- Can you attach the preprocessed source because I cannot reproduce using your code segment. I want to say something is defining block_size to some number. -- pinskia at gcc dot gnu dot org changed: What|Removed |Added CC||pinskia at gcc dot gnu dot ||org http://gcc.gnu.org/bugzilla/show_bug.cgi?id=24405
