   4 Subject: [PATCH 3/4] tests/bench-slope.c: workaround ICE failure on mips with
   5  '-O -g'
   6
   7 Hit a ICE and could reduce it to the following minimal example:
   8
   9 1. Only the size of array assigned with 2 caused the issue:
  10 $ cat > mipgcc-test.c << END
  11
  12 int main (int argc, char **argv)
  13 {
  14         char *pStrArry[ARRAY_SIZE_MAX] = {"hello"};
  15         int i = 0;
  16
  17         while(pStrArry[i] && i<ARRAY_SIZE_MAX)
  18         {
  19                 printf("%s\n", pStrArry[i]);
  20                 i++;
  21         }
  22
  23         return 0;
  24 }
  25
  26 END
  27
  28 2. Only -O1 and -g on mips caused the issue:
  29 $ mips-poky-linux-gcc -O1 -g -o mipgcc-test mipgcc-test.c
  30 mipgcc-test.c: In function 'main':
  31 mipgcc-test.c:18:1: internal compiler error: in dwarf2out_var_location,
  32 at dwarf2out.c:20810
  33  }
  34  ^
  35 Please submit a full bug report,
  36 with preprocessed source if appropriate.
  37 See <http://gcc.gnu.org/bugs.html> for instructions
  38
  39 3. The quick workround is trying to enlarge the size of array with
  40 larger
  41 than 2.
  42
  43 4. File a bug to GNU, but it could not be reproduced on there
  44 environment.
  45 http://gcc.gnu.org/bugzilla/show_bug.cgi?id=60643
  46
  47 Upstream-Status: Inappropriate [oe specific]
  48
  49 Rebase to 1.8.0
