This testcase
------------------------
int g(int i) {
if (i<1) {
const int x[3] = { 1,2,3 };
return x[i];
} else {
const int x[3] = { 4,5,6 };
return x[i];
}
}
-----------------------
now gives the following message on tree-ssa:
g/x> /home/bangerth/bin/gcc-tree-ssa/bin/c++ -c x.cc
/tmp/cc82Kcxj.s: Assembler messages:
/tmp/cc82Kcxj.s:13: Error: symbol `_ZZ1giE1x' is already defined
Richard, I guess this is due to your fixes to PR 12814 and
PR 13798. Would you mind taking a look? The reason seems to
be that if I mark the two variables "x" as static, then they
get assigned different names: _ZZ1giE1x and _ZZ1giE1x_0. However,
with your recent patch to turn constant arrays into statics, this
is not the case: both variables end up having the same name.
Thanks
Wolfgang
