The following code:
uint func()
{
asm
{
naked;
inc [EAX];
inc byte ptr [EAX];
inc short ptr [EAX];
inc int ptr [EAX];
inc long ptr [EAX];
}
}
generates:
__D5test24funcFZk:
inc byte ptr [EAX]
inc byte ptr [EAX]
inc word ptr [EAX]
inc dword ptr [EAX]
inc byte ptr [EAX] <== !!!!!
The last instruction should be rejected by the compiler.
