[LLVMdev] Incorrect loop optimization when building the Linux kernel
Nick, consider:
char a[0];
char b[0];
at run-time:
(gdb) p &a
$1 = (char (*)[]) 0x60103c
(gdb) p &b
$2 = (char (*)[]) 0x60103c
Even if this is not safe at the C or C++ level, this comparison could
return equal or not equal depending on what the linker chooses to do.
Do we have a bug in the constant folder?
