[Bug c++/35387] __PRETTY_FUNCTION__ produces inconsistent output
--- Comment #6 from d dot frey at gmx dot de 2008-02-28 08:14 --- I looked at bug #99, but I am unsure whether this bug is really a dup of it. #99 is about overloads and occurs with user types, while this bug is about partial template specializations and occurs only with certain types from the STL. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=35387
[Bug target/35295] 64-bit host cross compile to 32-bit target differs from 32-bit host cross compile to 32-bit target
--- Comment #12 from benny at ammitzboell-consult dot dk 2008-02-28 08:18 --- We have now tried the 4.2.3 version of gcc and it generates the same assembler code (objdump -d) for the example here on both the 32-bit and the 64-bit host. The RTL is still different though, so it seems you're right about it being a target issue. We're trying to build a full toolchain with gcc 4.2.1 to verify that result in a full-blown test on all of our code. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=35295
[Bug c++/35397] New: Problem handling denormalized numbers under AIX
I face a problem when trying to convert string to double numbers, when the
string represents a denormalized number.
I use g++ 4.2.2 on powerpc-ibm-aix5.3.0.0.
Example:
-
#include vector
#include sstream
#include iostream
int main() {
std::stringstream stream(5.6 0 0.205867 1.0809 7.22644 0.373206
-5.84675e-317 1.5 0.00433641 1.45331e-45);
std::vectordouble vals;
double x;
while (stream x)
{
vals.push_back(x);
}
std::vectordouble::iterator it;
for (it=vals.begin(); itvals.end(); it++) {
std::cout*it ;
}
return 0;
}
--
displays: 5.6 0 0.205867 1.0809 7.22644 0.373206
The denormalized number -5.84675e-317 is dropped and the loop ends.
Interestingly, if I use:
--
double x;
std::string st;
while (stream st) {
x = atof(st.c_str());
vals.push_back(x);
}
-
then that works, this displays: 5.6 0 0.205867 1.0809 7.22644 0.373206
-5.84675e-317 1.5 0.00433641 1.45331e-45
I have seen there were some denormalized-related options for g++ on Alpha, but
they are not implemented on AIX. Moreover, I don't see this issue under
Linux/gcc 4.2.2.

There's more to it... using the result syntax for the function makes it fail
even with my patch
That's because the result symbol is not marked with attr.always_explicit, only
the procedure symbol. I think it's more convenient to mark both:

I can only test in x86_64-unknown-linux-gnu.
make -k check RUNTESTFLAGS=--target_board=unix/-m32 will run the testsuite in
32bit mode.
BTW: make -j2 -k check RUNTESTFLAGS=--target_board=unix/\{,-m32\} will run
both, 64bit and 32bit testsuite. Two cores are recommended for -j2.

[Bug target/25477] builtin functions should use $LDBL128 suffix on darwin when appropriate
--- Comment #65 from ubizjak at gmail dot com 2008-02-28 11:29 ---
(In reply to comment #62)
The first situation was clearly better, but I was at work when Dominique
emailed my after my first commit, saying the new testcase FAILed, and I got
confused. I think I'll revert to the old situation, and we'll live with that
one FAIL until Apple fixes the bug or the universe stops expanding and
condenses into a single point of pure energy, whichever happens first. (My
money is on the second guess.)
Please note, that the syntax of dg-xfail-if is
dg-xfail-if message {targets} {include} {exclude}
so perhaps adding another dg-xfail-if line with someting like
dg-xfail-if apple libc problems { powerpc*-apple-darwin* } {* } {-O0}
would produce clean run.

[Bug rtl-optimization/35404] New: ra-conflict does not handle subregs optimally
I'm reporting this as an enhancement request to record a case where libcalls
are still used in the compiler.
Consider this test case:
extern long long bar();
long long foo () { return bar () | bar (); }
Compile it with -O2 -fno-wide-types. I'm using -fno-wide-types to permit using
a simple test case; without that option, the same issue would arise for more
complicated cases.
In the .lreg dump I see this:
(insn:HI 9 8 10 2 /home/iant/foo4.c:2 (parallel [

(ior:SI (subreg:SI (reg:DI 58 [ D.1180 ]) 0)

This is a libcall sequence which represent a no-conflict block. It was created
by emit_no_conflict_block. It means that register 61 does not conflict with
either register 58 or 59.
It is desirable to detect this fact in some other way. If we can do that, then
we have eliminated one case where we use libcalls.
If we can track subreg lifetimes, then we can detect that there is no
conflicts. Register 58 and 59 dies in insn 10. Insn 10 does not refer to
subreg 0 of either register. Therefore, subreg 0 of both registers die in insn
9. Therefore we can know that there is no conflict between register 61 and
either register 58 or 59.
The code in ra-conflict.c tries to track subreg lifetimes. However, it does
not detect this case. In the greg dump file, I see this:
;; 58 conflicts: 61 59 0 1 3
;; 59 conflicts: 61 58 0 1 3
;; 61 conflicts: 58 59 1 3 4
Ideally this should be
;; 58 conflicts: 59 0 1 3
;; 59 conflicts: 58 0 1 3
;; 61 conflicts: 1 3 4
I will attach an old patch I have which was able to make this sort of
determination. This patch is pre-DF, pre-ra-conflict, and is certainly not
applicable today.

I knew I was missing something :)
I try again... this time, with less ambition, just fix the case at hand... this
should not break anything (but... I can't regtest right now).

[Bug ada/33857] Cannot bootstrap Ada with host gnatmake-4.2
--- Comment #7 from dave at hiauly1 dot hia dot nrc dot ca 2008-02-29 04:47 --- Subject: Re: Cannot bootstrap Ada with host gnatmake-4.2 I tried the setenv change with 4.2.3. Had to apply the -larg -lgcc_eh hack to Make-lang.in to do an initial bootstrap. After installing this build, the hack isn't needed. I'll post testresults for 4.2.3 on 10.5.2 soon. Couldn't post 4.2.3 results. Gcc and acats are ok, but g++ and libstdc++ are a disaster. ld segfaults in many tests. Some 4.3.0 results are here: http://gcc.gnu.org/ml/gcc-testresults/2008-02/msg01915.html As can be seen, ada is in excellent shape on this target.
