--- Comment #10 from prathamesh3492 at gcc dot gnu.org ---
On a related note, Jim told me he is seeing following failures
on aarch64-none-elf before and after updating the tree.
FAIL: gcc.c-torture/execute/builtins/memset-chk.c execution, -O2
-flto -fuse-linker-plugin -fno-fat-lto-objects
FAIL: gcc.c-torture/execute/builtins/snprintf-chk.c execution, -O2
-flto -fuse-linker-plugin -fno-fat-lto-objects
FAIL: gcc.c-torture/execute/builtins/vsnprintf-chk.c execution, -O2
-flto -fuse-linker-plugin -fno-fat-lto-objects
However he isn't seeing the failure for strcat-chk.c before or after.
Before he updated the tree, it was older than 23rd Nov, which didn't
contain r242745. Perhaps the issue is sth else ?
Bin, are you able to see the above test-cases FAIL too ?
Thanks,
Prathamesh
