[Bug tree-optimization/20514] New: hoisting of label out of jumptable would take place at cse, should happen at trees
The following testcase from bug 18628 exposes a case in which cse would have
folded a load from a jump table into a label. Jeff suspects this should have
happened earlier, in the tree level, so he asked me to file this bug. Here's
the testcase:
int i;
int main()
{
for (;;)
{
switch (i)
{
case 0:
case 1:
return 1;
case 2:
case 3:
return 0;
case 5:
--i;
}
}
}

[Bug pch/20315] pch problems on solaris
--- Additional Comments From cmarco at indra dot es 2005-03-17 08:55 --- (In reply to comment #2) Confirmed, but the question is why do you need to generate the PCH twice? Header files never produce object files, unlike in Ada. Also removing the PCH file is enough to solve the problem. Perhahs, I have a concept problem. If you have a c++ template in a .h file without a .c file and you compile it you should obtain a .o object. I do not need any .gch file So this happens with the 3.2.3 version. sun1:~/test g++ -v Reading specs from /usr/local/gcc-3.2.3/bin/../lib/gcc-lib/sparc-sun- solaris2.9/3.2.3/specs Configured with: ./configure --prefix=/usr/users/afernand/comp/gcc-3.2.3 - enable-language=c,c++ Thread model: posix gcc version 3.2.3 sun1:~/test ls -la test* -rw-r- 1 cmarco indra141 Mar 3 16:49 test.h sun1:~/test g++ -m64 -x c++ -c test.h sun1:~/test ls -la test* -rw-r- 1 cmarco indra141 Mar 3 16:49 test.h -rw-r- 1 cmarco indra672 Mar 17 09:18 test.o Now if I use the 3.4.4 version: sun1:~/test g++ -v Reading specs from /usr/local/gcc-34/bin/../lib/gcc/sparc-sun- solaris2.9/3.4.4/specs Configured with: ./configure --prefix=/usr/users/afernand/comp/gcc-bootstrap- 34 --enable-language=c --without-headers --disable-shared : (reconfigured) ./configure --prefix=/usr/users/afernand/comp/gcc-bootstrap-34 - -enable-language=c --without-headers --disable-shared : (reconfigured) ./configure --prefix=/usr/users/afernand/comp/gcc-bootstrap-34 - -enable-language=c --without-headers --disable-shared : (reconfigured) ./configure --prefix=/usr/users/afernand/comp/gcc-34 --enable- language=c,c++ Thread model: posix gcc version 3.4.4 20041222 (prerelease) sun1:~/test ls -la test* -rw-r- 1 cmarco indra141 Mar 3 16:49 test.h sun1:~/test g++ -m64 -x c++ -c test.h sun1:~/test ls -la test* -rw-r- 1 cmarco indra141 Mar 3 16:49 test.h -rw-r- 1 cmarco indra1034879 Mar 17 09:23 test.h.gch Something have change. ¿Should I have use other options? -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=20315
[Bug ada/20515] New: stdcall imports are not handled correctly
When using a GCC cross-compiler from GNU/Linux to Windows with Ada support, the
link names of pragma Import with Convention stdcall are not mangled correctly
and thus linking to the Windows API does not work.
A small example is:

with Ada.Calendar;
procedure Time is
T : Ada.Calendar.Time;
begin
T := Ada.Calendar.Clock;
end Time;

I don't see any benefit in calling gimple_add_tmp_var *after*
gimplifying the initializer, so I moved the call before that, which
enabled me to get the C++-specific compound-literal-expr gimplifier to
not call gimple_add_tmp_var at all.
As for handling compound-literal-expr cleanups, this patch does so by
using target_expr gimplification code, replacing the
compound-literal-expr with a target_expr when the
compound-literal-expr is found to need a cleanup, and immediately
gimplifying that. This avoids duplicating the code from a number of
static functions in gimplify.c, but I'm open to other approaches, such
as exporting gimple_push_cleanup from gimplify.c.
Tested on x86_64-linux-gnu. Ok to install?

[Bug c++/20516] New: Function names affect template compilation
The following code compiles if (and only if) the global function name and A's
member function name are identical. It shouldn't, because a.template should be
used inside the test() function in the global scope.
template class T class A
{
public:
template class U void test(T value) {}
};
template class T void test(AT a, T val)
{
a.testint(val); //should be a.template testint(val);
}

{

[Bug rtl-optimization/20211] autoincrement generation is poor
--- Additional Comments From amylaar at gcc dot gnu dot org 2005-03-17 16:37 --- (In reply to comment #4) There are both primary and secondary platforms among the AUTO_INC_DEC targets. So it is probably good to gain some wider test coverage about the compile- time/run-time impact of this. E.g. testing CSIBE on ARM, or SPEC on RS6000. I currently don't have an ARM or RS6000 platform to run benchmarks on. We are looking into setting up a powermac for this task, though. AFAICS RS6000 provides register+offset addressing for all modes except the altivec vector modes, so to see any significant benefit from optimize_related_values, the benchmark should have multiple altivec memory accesses from the same structure / array in a single basic block. One of the common complaints of RTL code is that monolithic files containing multiple optimization passes (with interwinded functions) and with undocumented public interface is a maintenance mess. Compare that with tree-ssa where each pass lives in its own small[1] file and just exposes the pass description structure. I believe it would be great if the new pass could be live in its own file. The utility functions currently in regmove could be extracted in regmovelib or whatever name fits best. I am willing to make that change, but would first like to hear from a global or middle-end maintainer that they agree that this is a move in the right direction. Also, there are some details that should be agreed on first. I.e.: Should tehre remain a toplevel regmove function that calls mark_flags_life_zones first, and then the sub-passes, or should each sub-pass call mark_flags_life_zones? If there is such a toplevel functiojn, would it live in the regmove* files, or would that be rest_of_handle_regmove in passes.c ? Where does the combine_stack_adjustments pass belong? Should it be in flow.c, or in it's own file (combine_stack_adj.c ?) -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=20211

[Bug fortran/20520] New: allocatable arrays may be used without being allocated
The compiler does not display an error message when in a source file allocatable arrays are being used without having been allocated beforehand. For example, the following code is erroneous, but nevertheless the compiler will compile (and build) it silently: real,allocatable:: a(:),b(:) a(1)=2*b(1) end Of course, the executable produced will collapse when run. The gfortran compiler used was the standalone package for Windows (downloaded as a zip archive). -- Summary: allocatable arrays may be used without being allocated Product: gcc Version: 4.0.0 Status: UNCONFIRMED Severity: normal Priority: P2 Component: fortran AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: ebertakis at gmail dot com CC: gcc-bugs at gcc dot gnu dot org http://gcc.gnu.org/bugzilla/show_bug.cgi?id=20520

Found while building rhino's js.jar. Grab js.jar from http://spindazzle.org/js.jar (sources from JPackage.org).

.ident GCC: (GNU) 3.4.3
8--8-8-
That means the optimizer eats
fix_029_n089n196:
.quad 0x98ea46e098ea46e
.text
which causes an undefined reference to 'fix_029_n089n196' later
when linking the executable.
Can you check this?
Thanks.
