[Bug c++/13898] New: [tree-ssa] duplicate symbol for local variable turned static

[bangerth at dealii dot org]

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
