I just tried to compile the Linux kernel 2.6.28.5
with the GNU C compiler version 4.4 snapshot 20090206,
using the valgrind debugging tool.
The compiler said
as --gdwarf2 -V -Qy --64 -o arch/x86/ia32/ia32entry.o ia32entry.s
==4085== Conditional jump or move depends on uninitialised value(s)
==4085== at 0x41D56E: (within /usr/bin/as)
==4085== by 0x405DC4: (within /usr/bin/as)
==4085== by 0x5976585: (below main) (in /lib64/libc-2.9.so)
File ia32entry.s attached.
$ as -v
GNU assembler version 2.19 (x86_64-suse-linux) using BFD version (GNU Binutils;
openSUSE 11.1) 2.19
