tools/nolibc: x86-64: Use `mov $60,%eax` instead of `mov $60,%rax`
[ Upstream commit 7bdc0e7a ] Note that mov to 32-bit register will zero extend to 64-bit register. Thus `mov $60,%eax` has the same effect with `mov $60,%rax`. Use the shorter opcode to achieve the same thing. ``` b8 3c 00 00 00 mov $60,%eax (5 bytes) [1] 48 c7 c0 3c 00 00 00 mov $60,%rax (7 bytes) [2] ``` Currently, we use [2]. Change it to [1] for shorter code. Signed-off-by: Ammar Faizi <ammar.faizi@students.amikom.ac.id> Signed-off-by: Willy Tarreau <w@1wt.eu> Signed-off-by: Paul E.
