[Bug fortran/28914] Code inside loop hangs; outside loop runs normally; runs OK on other compilers
--- Comment #8 from paul dot richard dot thomas at cea dot fr 2006-09-04 12:08 --- Even simpler is: trans-array.c(gfc_trans_array_constructor_value) replace loopvar = se.expr; byloopvar = gfc_evaluate_now (se.expr, pblock); gfc_expand_constructor is called from resolve_expr and from three places in expr.c. As far as I can tell, non-initialization expressions only try the expansion from resolve_expr. If I flag the calls to distinguish them and limit the maximum number of expanded elements to 10, say, in gfc_expand_constructor, the code reflects this but the compilation time does not. Something, somewhere is doing a temporary expansion of the constructor, which is taking all the time. I have to leave this again but I will get to the bottom of it.

--- Comment #7 from jakub at gcc dot gnu dot org 2006-09-04 12:14 --- I have downloaded your tarball and it seems you are not building gcc to default to 128-bit long double on a glibc 2.4+ system. That's very bad idea, you either shouldn't have upgraded to glibc 2.4+, or should have switched everything to 128-bit long double. While --with-long-double-128 libstdc++.so.6 is ABI compatible with older one, --without-long-double-128 exact ABI of the math stubs depends on whatever configure tests find out. With older glibc's, log10l etc. is not in system libm (long double was just 64-bit there and so log10 did the same), but with glibc 2.4+ it is present in libm (and implements the 128bit long double logarithm etc.).

--- Comment #3 from kumura at r2 dot dion dot ne dot jp 2006-09-04 12:48 --- When I ported gcc to our processor architecture a year ago, I found this might be a problem. But, now things have changed. Old version of the function reg_overlap_mentioned_for_reload_p() had abort() in it and the function abort() was activated when reg_overlap_mentioned_for_reload_p() was invoked with a pseudo register.

[Bug tree-optimization/28948] New: -fprofile-generate/use and C++ anonymous namespaces don't mix
As the subject says. Take this:
-
namespace {
void f() {}
}
int main () {
f();
}
-
and then do this:
g/x> c++ -fprofile-generate x.cc ; ./a.out
g/x> c++ -fprofile-use x.cc
x.cc: In function 'void::f()':
x.cc:6: error: coverage mismatch for function
'_ZN33_GLOBAL__N_x.cc__3836C1911fEv' while reading counter 'arcs'
x.cc:6: error: checksum is 87e5f01 instead of fec92a63
This is due to the fact that gcc mangles anonymous namespace members with
different names every time it compiles the file. -fprofile-use should take
that into account.
Note that some libstdc++ has some anonymous namespaces. Consequently, some
programs that use libstdc++ will not be able to use -fprofile-generate/use
and there is nothing a program author can do about it.
Best
W.

voidAddElement (const T& val) { _array[Newidx()] = val; }
I think this code contains unspecified behavior.
There are no sequence points between the this->_array and the function call
Newidx() so we load this->_array before the function call which is valid
according to the C++ standard.
Can you try changing AddElement to:
voidAddElement (const T& val) { int newidx = Newidx(); _array[newidx] =
val; }
And try again?

Otherwise, build process uses some external software that must be installed before build. Where it is installed has nothing to do with gcc build configuration and installation tree conventions. We have to configure arbitrary directories / compiler options for this. With `Makefile.in' as it is currently one can not do that. It sets this external software option unconditionally to point to `$(exec_prefix)/$(target_noncanonical)/bin' directory - with variables from build configuration of gcc, not of that external software. It will break build if the external software to use is actually installed elsewhere, and software in `$(build_tooldir)/bin/' also exists, but behaves in a quite different way. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=28472

--- Comment #4 from pinskia at gcc dot gnu dot org 2006-09-05 04:52 --- Actually it looks like an oversight of what relayout_decl does. The reason is that relayout_decl was added by the patch to fix "PR c++/16115" and I think Jason forgot about user specified alignment because he was only dealing with PARM_DECLs at the time. Anyways I am going to test the obvious fix unless you (Ulrich) want to do it. -- pinskia at gcc dot gnu dot org changed: What|Removed |Added AssignedTo|unassigned at gcc dot gnu |pinskia at gcc dot gnu dot |dot org |org Status|NEW |ASSIGNED http://gcc.gnu.org/bugzilla/show_bug.cgi?id=28862

For some processors, it is an optimization to avoid > partial flag register stall. When it is fixed, it should be reenabled with a > new flag, something like TARGET_PARTIAL_FLAG_REG_STALL. There is TARGET_USE_INCDEC flag that already implements your suggestion. >From predicates.md: /* On Pentium4, the inc and dec operations causes extra dependency on flag registers, since carry flag is not set. */ if (!TARGET_USE_INCDEC && !optimize_size) If used elsewhere, this flag should perhaps be renamed to proposed TARGET_PARTIAL_FLAG_REG_STALL. -- uros at kss-loka dot si changed: What|Removed |Added CC||uros at kss-loka dot si http://gcc.gnu.org/bugzilla/show_bug.cgi?id=28946
