libgcrypt: 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 [YOCTO #6034] 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 (From OE-Core rev: 4af0c70c70809c8f03d7ba14745d79e3c6e35b2e) Signed-off-by: Hongxu Jia <hongxu.jia@windriver.com> Signed-off-by: Saul Wold <sgw@linux.intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>

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.
