Subject: [PATCH 3/4] 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.
|
|
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=60643
|
|
|
|
Upstream-Status: Inappropriate [oe specific]
|
|
|
|
Rebase to 1.8.0
