tests/bench-slope.c: workaround ICE failure on mips with '-O -g'
Hit a ICE and could reduce it to the following minimal example:
1. Only the size of array assigned with 2 caused the issue:
$ cat > mipgcc-test.c << END
int main (int argc, char **argv)
{
char *pStrArry[ARRAY_SIZE_MAX] = {"hello"};
int i = 0;
while(pStrArry[i] && i<ARRAY_SIZE_MAX)
{
printf("%s\n", pStrArry[i]);
i++;
}
return 0;
}
END
2. Only -O1 and -g on mips caused the issue:
$ mips-poky-linux-gcc -O1 -g -o mipgcc-test mipgcc-test.c
mipgcc-test.c: In function 'main':
mipgcc-test.c:18:1: internal compiler error: in dwarf2out_var_location, at dwarf2out.c:20810
}
^
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions
3. The quick workround is trying to enlarge the size of array with larger
than 2.
4. File a bug to GNU, but it could not be reproduced on there environment.
