[Bug libfortran/48906] Wrong rounding results with -m32
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48906 --- Comment #19 from Thomas Henlich thenlich at users dot sourceforge.net 2011-06-01 06:26:27 UTC --- Also, the test case, pr20755.f was originally intended to pass only with -std=legacy. This is to mimic g77 which does not ignore the scale factor. At least recently, gfortran passes this test case regardless of the -std=. I am tempted to delete the test case, since it looks like it goes against current standards. Any opinions about this? Now you've lost me. From what I understand PR20755 was about G editing resetting the scale factor in certain cases (to 0 in the example) and not restoring it afterwards (to 1 in this case). This is a bug both in legacy and in Fortran standard modes. The bug was fixed and a testcase was created. The result is standard-compliant. Why would you want to remove the testcase? The point of having a testcase is to prevent a reappearing of the same bug in the future, so maybe we should keep it.

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48906 --- Comment #20 from Thomas Henlich thenlich at users dot sourceforge.net 2011-06-01 08:12:31 UTC --- (In reply to comment #18) Created attachment 24406 [details] New updated patch This updated patch takes care of Comment #16. Unfortunately, now the other testcases fail again (although with still another results): print (ru,g15.2), .099d0 ! 0.10E-01 expected 0.10 print (rc,g15.1), .095d0 ! 0.1E-01 expected 0.1 print (rc,g15.2), .0995d0 ! 0.10E-01 expected 0.10 print (ru,g15.3), .0999d0 ! 0.100E-01 expected 0.100 print (rc,g10.2), 99.5 ! 0.10E+02 expected 0.10E+03 print (rc,g10.2), 995. ! 0.10E+03 expected 0.10E+04 print (rc,g10.3), 999.5 ! 0.100E+03 expected 0.100E+04 print (rc,g10.3), 9995. ! 0.100E+04 expected 0.100E+05 It seems there is still a bug that doesn't increment the exponent in the overflow case, i.e. when going from 0....E(x) to 0.1000...E(x+1) The exponent test (decision between F and E editing) must be done after that! I can not find this in the code right now.
[Bug c++/49251] New: [C++0x][parameter pack expanding] unused parameter warning with unpacking empty tuples
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49251
Summary: [C++0x][parameter pack expanding] unused parameter
warning with unpacking empty tuples
Product: gcc
Version: 4.6.0
Status: UNCONFIRMED
Severity: trivial
Priority: P3
Component: c++
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: gintensub...@gmail.com
#include tuple
template std::size_t... Indices
struct indices {};
template class... Args
void sink( Args... ) {}
template class Tuple, std::size_t... Indices
void unpack_test( Tuple t, indicesIndices... ) {
sink( std::getIndices(t)... );
}
int main() {
unpack_test( std::tuple(), indices() );
}
This code, which is unpacking tuples, raises unused parameter warning:
$ g++ -std=c++0x -Wunused-parameter bug.cc
bug.cc: In instantiation of 'void unpack_test(Tuple, indicesIndices ...)
[with Tuple = std::tuple, unsigned int ...Indices = {}]':
bug.cc:15:44: instantiated from here
bug.cc:10:6: warning: unused parameter 't' [-Wunused-parameter]
I've confirmed this behavior on following versions:
4.5.0
4.5.3
4.6.0
4.6-20110527
4.7-20110528
It can be avoided by using the parameter explicitly, like `(void)t;',
but it's not always used.
( For example, it cannot be used for constexpr functions. )

[Bug c/49257] New: -mfpmath=sse generates x87 instructions on 32 bits OS
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49257 Summary: -mfpmath=sse generates x87 instructions on 32 bits OS Product: gcc Version: 4.5.1 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c AssignedTo: unassig...@gcc.gnu.org ReportedBy: olivier_ma...@mentor.com Created attachment 24408 -- http://gcc.gnu.org/bugzilla/attachment.cgi?id=24408 simple reproducer Hi, Please find attached a simple C program that shows the issue. I compile it that way: gcc -O0 simple.c -mfpmath=sse -msse3 -o ok.exe ./ok.exe returns the correct value gcc -O0 simple.c -mfpmath=sse -msse3 -DRETURN_NAN -o nan.exe ./nan.exe returns a NAN Both exe use some gcc intrinsic that change the FP stack into mmx registers. It is expected that if I call a libc function (like printf) without restoring the stack to its original state (using emms) then I'll have a wrong behavior. But, here, because of the following assembly code: .L4: fildq 72(%esp) cmpl$0, 76(%esp) jns .L3 fldt.LC2 faddp %st, %st(1) .L3: fstpl 24(%esp) movsd 24(%esp), %xmm0 mulsd 56(%esp), %xmm0 movsd %xmm0, 40(%esp) movl68(%esp), %eax movl4(%eax), %edx movl(%eax), %eax movl52(%esp), %ecx movl%eax, 16(%esp) movl%edx, 20(%esp) movq16(%esp), %mm0 movntq %mm0, (%ecx) addl$1, 72(%esp) adcl$0, 76(%esp) .L2: cmpl$0, 76(%esp) jb .L4 cmpl$0, 76(%esp) ja .L6 cmpl$9, 72(%esp) jbe .L4 I've got a NAN why I shouldn't !? The instruction that generates that x87 code is the line (double)i * coeff; where i is an unsigned long long and coeff is a double. It works well if for instance 'i' is a long/int/unsigned int. Maybe that behavior is expected ? BR Olivier

Since config can't correctly determine in all cases whether an implementation has a fast enough sincos/cexp, the few targets where the current flags don't work should be able to disable the transformation. I can create a cse-sincos option flag, set on by default for most platforms. The darwin platform maintainer (and others, if necessary) could add -fno-cse-sincos to the platform defaults.

For some bit patterns of the immediate constant it tries to extract the bits in question by various means and test the result against zero/non-zero and misses the straight forward instruction. In particular: * one single bit * n contiguous bits starting at bit 0 When testing a byte against 0x80 it uses CMP/PZ, which is as good as a TST instruction (in terms of costs), so this is OK.

[Bug target/49263] SH Target: underutilized TST #imm, R0 instruction
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49263 --- Comment #1 from Oleg Endo oleg.e...@t-online.de 2011-06-01 20:42:00 UTC --- Created attachment 24412 -- http://gcc.gnu.org/bugzilla/attachment.cgi?id=24412 Proposed Patch Although the patch gets the job done, programmer's sense tells me it is fishy, or at least pretty much brute forced cure of the symptoms, not the cause. It's my first GCC patch, so any feedback is highly appreciated. What I did was looking at the RTL, in particular the combine pass, identifying patterns it failed to find a shortcut (tst insn) for and adding them to the insn descriptions. I also had to expand the costs calculation of the AND instruction to cover AND, OR and XOR (on SH they are the same anyways), or else the cost of a matched replacement insn would result in a rejection in the combine pass.

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44897 --- Comment #20 from Jan Hubicka hubicka at gcc dot gnu.org 2011-06-02 01:12:12 UTC --- The problem as confirmed in Comment 9 no longer reproduce on mainline. So problem is either fixed or went latent. I am going to try 4.6.
[Bug libfortran/48906] Wrong rounding results with -m32
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48906 Jerry DeLisle jvdelisle at gcc dot gnu.org changed: What|Removed |Added Attachment #24406|0 |1 is obsolete|| --- Comment #22 from Jerry DeLisle jvdelisle at gcc dot gnu.org 2011-06-02 03:57:49 UTC --- Created attachment 24414 -- http://gcc.gnu.org/bugzilla/attachment.cgi?id=24414 Fixed revised patch This patch fixes my omissions on the last patch. In addition, studying the test case pr20755.f, I see that it has the wrong number of significant digits in the expected result. I have revised it now so that it passes. I have also added a new test case, to capture the various errors we found here while developing the patch Feel free to continue testing and if no new errors show up, I will submit to the gfortran list for approval. /me crosses his fingers. ;)
