[Bug tree-optimization/50955] [4.7 Regression] IVopts incorrectly rewrite the address of a global memory access into a local form.
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=50955
--- Comment #15 from Andrew Pinski ---

Before IV-OPTS I have this use:
i.17_13 = (sizetype) i_52;
D.13668_14 = i.17_13 + -1;
D.13669_15 = D.13668_14 * 4;
D.13670_16 = D.13666_12 + D.13669_15;
att_17 = *D.13670_16;
But we decided that it was not used as an address here though. We have:
(gdb) p *use->iv
$15 = {base = 0x777e1c60, base_object = 0x0, step = 0x777e1c60,
ssa_name = 0x0, biv_p = 0 '\000',
have_use_for = 1 '\001', use_id = 0}
(gdb) p *use
$16 = {id = 3, type = USE_NONLINEAR_EXPR, iv = 0x1376bb0, stmt =
0x7727c780, op_p = 0x0, related_cands = 0x0,
n_map_members = 10, cost_map = 0x13de580, selected = 0x0}

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=58174 --- Comment #2 from Rafał Mużyło --- By "miscompiles", in this case I mean there's no error during compilation, but the produced executable fails to work. I'm not very familiar with the code of the project, that this file comes from, but it's a quite complex bit of C++, which makes it difficult (on my skil level) to tell what exactly goes wrong. I've only managed to find which source file was the apparent culprit of the crash upon running.

The configuration notes read: "To enable symbol versioning in ‘libstdc++’ with Sun ld, you need to have any version of GNU c++filt, which is part of GNU binutils. ‘libstdc++’ symbol versioning will be disabled if no appropriate version is found. Sun c++filt from the Sun Studio compilers does not work." so I'd try to download and compile a recent version of GNU binutils. > Here we have only the non-GNU version: > > [local@raymund7:~]>which c++filt > /opt/solarisstudio12.3/bin/c++filt > [local@raymund7:~]>c++filt --version > Could not open input file "--version" > > Ok, I see ... maybe the filter step has been skipped??? Yes, and this means that the library isn't versioned.

This is not surprising we have one in MIPS too. Though I did test on mips64 (only n64 and n32 and not loongson though).

[Bug fortran/58177] New: Incorrect warning message about unused PRIVATE module variable
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=58177 Bug ID: 58177 Summary: Incorrect warning message about unused PRIVATE module variable Product: gcc Version: 4.9.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: fortran Assignee: unassigned at gcc dot gnu.org Reporter: abensonca at gmail dot com With gfortran 4.9.0 (r201758) the following incorrectly reports than the variable "m" in module "b" is unused: module a logical :: m end module a module b logical, private :: m contains subroutine bb() use a m=.true. end subroutine bb end module b $ gfortran -v Using built-in specs. COLLECT_GCC=gfortran COLLECT_LTO_WRAPPER=/home/abenson/Galacticus/Tools/libexec/gcc/x86_64-unknown-linux-gnu/4.9.0/lto-wrapper Target: x86_64-unknown-linux-gnu Configured with: ../gcc-trunk/configure --prefix=/home/abenson/Galacticus/Tools --enable-languages=c,c++,fortran --disable-multilib --with-gmp=/home/abenson/Galacticus/Tools Thread model: posix gcc version 4.9.0 20130815 (experimental) (GCC) $ gfortran -c bug.F90 -o bug.o -Wall bug.F90:5.23: logical, private :: m 1 Warning: Unused PRIVATE module variable 'm' declared at (1) The variable "m" in module "b" is used. The problem seems to be related to the presence of a PUBLIC variable with the same name in another USEd module. Changing the name of the variable in the USEd module makes the warning go away. Renaming the imported variable with: use a, only : mm => m results in a correct warning: Warning: Unused module variable 'm' which has been explicitly imported at (1) and causes the "Unused PRIVATE" warning to go away.

static int x;
struct B :base{
void f() {
x++;
printf("x= %d\n",x);
