[Bug c/10719] invalid code generated (x86, int $5) with __builtin_va_arg(va, char);
--- Additional Comments From falk at debian dot org 2005-09-13 06:19 --- (In reply to comment #16) Oh? I had -Werror on, and was not getting any warning at all from my code that was generating 'int $0x5' with gcc 3.4.1. It's perhaps a slightly different case than comment 0, because I was casting an int to a char* in the varargs? Please attach a test case. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=10719

Remarks:
Wasn't able to find any remarks about this particular case in bugzilla (terms:
cast, visib, accessibl), nor
did I find a comment about C++ language changes in the 3.4 release docs. I
suspect either this is a
reject-valid bug, OR there's something in the standard that says this is
invalid, and that 3.4+ are just
conforming to it. (Or I'm extremely tired and my eyes just glossed over it.)
If invalid, kindly reference

[Bug target/23687] Crosscompiler looks for files it never built
--- Additional Comments From rsandifo at gcc dot gnu dot org 2005-09-13 07:50 --- Re crti.o and crtn.o: can I just check that you unpacked unmodified FSF sources, configured with those arguments, ran make, and that make completed successfully, but that crti.o and crtn.o were somehow not built? If so, I'll need a log of the make process. FWIW, many people build cross mips*-linux-gnu compilers, and I don't remember ever hearing of this kind of problem before. In case it helps debugging, the rules to make crti.o and crtn.o are in config/mips/t-elf. As discussed on the gcc lists, crt1.o and friends are provided by glibc. Using newlib for mips*-linux-gnu is basically unsupported. I wouldn't recommend trying it unless you're really keen on sorting through the fallout yourself ;) If you want us to look at the ICE, we'll need preprocessed input.

i.e. containing an loop-invariant check if (ie 0).
Both DOM and copy-header do this transformation. Disabling both

int i;
bb 0:
j = 0;
goto bb 4 (L4);

L4:;
if (j je) goto L8; else goto L5;
L8:;
i = 0;
goto bb 2 (L2);
L5:;
return;
}
which is a _lot_ faster for small ie. Optimally we would hoist the
loop invariant check out of the j loop.

[Bug tree-optimization/23855] Should not do loop header copying for inner loop
--- Additional Comments From rakdver at gcc dot gnu dot org 2005-09-13 13:29 --- It is not clear to me why you find the code without header copying better -- number of checks of each condition is exactly the same in both cases, and with right ordering of basic blocks, there should be one less jump executed. Depending on branch prediction on the target, either the original code or the code with copied headers may be faster, but it is hard to determine which one. Unswitching of non-innermost loops should not be hard to implement (most of code is in place, it only was quite some time that it was tested for anything but innermost loops, so there probably is some bitrot; and a few pieces on tree level may be missing). -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=23855

Well, it is the case that I have some numerical application that has
such loops and the case of small ie (1 or 2) does happen during boundary
updates, so instead of
if (ie = 0)
return;
for (j=0; jje; ++j)
i=0;
do {
foo();
i=i+1;
} while (iie);
and executing the if (ie = 0) exactly one time, we execute it
je times, which is as often as half times the number of total iterations
of the inner loop body. You are probably right that the execution number
without loop header copying is exactly the same, but unswitching this
condition certainly helps for small ie (where loop versioning with constant
ie and completely unrolled inner loop would help even more, of course).

[Bug c++/23849] inaccessible base in static_cast from template base type to non-template derived type
--- Additional Comments From bangerth at dealii dot org 2005-09-13 14:04
---
Here's a slightly smaller version:
-
struct A {};
struct B : private A {};
B *p = static_castB*((A*)0);
-
g/x /home/bangerth/bin/gcc-3.2.3/bin/c++ -c x.cc
g/x /home/bangerth/bin/gcc-3.4*/bin/c++ -c x.cc
x.cc:4: error: `A' is an inaccessible base of `B'
The code is rejected at least since gcc3.3.4pre. I must admit that I don't
know right away whether the code is legal -- icc for one accepts it -- though
I could think of arguments why it shouldn't be.

A key detail that you left out of your patch description is that SYSTEM_HEADER_DIR is used *only* for fixincludes and similar; it is not actually put into the compiler. If the path was used in the compiler, this patch would not be OK, because it would mean the compiler couldn't be moved to a different place after installation. I haven't looked at the patch again after reading his comment (just saw it now), but I intend to. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=22541

[Bug driver/23861] New: Build failure due to -pipe not working with .F90 and .F95 files
Bootstrapping with Fortran enabled fails for 4.0.1 if -pipe is included among flags passed through to library builds. It used to work for 4.0.0.

[Bug testsuite/23867] New: libstdc++ ABI testsuite should work for installed compiler testing
The libstdc++ ABI testsuite does not work when testing an installed compiler because: * abi.exp checks for ../src/.libs/libstdc++.so, which of course is not available with an installed compiler. * abi.exp requires baseline_file to be set in site.exp; with installed compiler testing, site.exp is generally created to set generic variables such as CC and CXX being the compilers to test, but not libstdc++-specific ones such as baseline_file. The testsuite should be arranged so that it can find the libstdc++ being used by an installed toolchain, and the logic to find the baseline file should be implemented within the testsuite. It would probably then no longer be necessary to restrict the ABI testing to native compilers only. Mark has asked for this PR to be assigned to him. -- Summary: libstdc++ ABI testsuite should work for installed compiler testing Product: gcc Version: 4.1.0 Status: UNCONFIRMED Severity: normal Priority: P2 Component: testsuite AssignedTo: mark at codesourcery dot com ReportedBy: jsm28 at gcc dot gnu dot org CC: gcc-bugs at gcc dot gnu dot org http://gcc.gnu.org/bugzilla/show_bug.cgi?id=23867

[Bug c/23869] New: Missed optimization with integer booleans when compiling for pentium and higher
On x86 architectures, when the target is -march=pentium or higher, the compiler
seems to replace (x || y) by ((x | y) != 0) too soon for optimizations to apply,
when x and y are integers.
Testcase (compiled with gcc -O3 -march=something):
typedef int T;
void g(T);
void f(T x, T y) {
if (x || y) return;
g(!x);
}
When the target is -march=i386, GCC is doing a great job and it is able to
replace !x by 1 when optimizing:
if (x || y) return;
g(1);
However, when the target is -march=pentium, the generated code is equivalent to:
if ((x | y) != 0) return; /* this is a bit better than previously */
g(x != 0);/* this is a lot worse */
If int is replaced by _Bool in the typedef, then the code is correctly
optimized: !x is replaced by 1 whatever the target. So the misoptimization is
triggered only when boolean values are passed through integers (quite a common
situation in C) and when some specific x86 architectures are targeted.

[Bug c/23870] New: continue hangs compiler (and whole computer!)
When I try to compile any of these functions below, GCC 3.4.4 hangs the whole
computer! I was needed to reboot my Feodore Core3 system - severe memory leak?
I'm compiling on a Linux machine running Feodore Core3 kernel 2.6.9.
The compiler is arm-elf-gcc-3.4.4 compiled with binutils-2.16.1, newlib-1.13.0.
I compiled binutils like this:
../../$BINUTILS_DIR/configure --target=$TARGET --prefix=$DEST
--disable-nls
make LDFLAGS=-s all install
I compiled GCC like this:
../../$GCC_DIR/configure --enable-languages=c,c++,f77 --target=$TARGET
--prefix=$DEST --with-gnu-as --with-gnu-ld --with-newlib --disable-nls
make LDFLAGS=-s all-gcc all-target-libstdc++-v3 install-gcc
install-target-libstdc++-v3
The code that hangs the compiler looks like this:
(Simplified stupid code example just to show the error.)
void hang_compiler1(signed long long x)
{
while (1) {
if (x 0)
continue;
}
}
void hang_compiler2(signed long long x)
{
for (;;) {
if (x 0)
continue;
}
}
void hang_compiler3(signed long long x)
{
do {
if (x 0)
continue;
} while (1);
}
