CONFIG_X86_IAMCU:

The IAMCU calling convention changes the X86 C calling convention to pass some arguments via registers allowing for code size and performance improvements. Great care needs to be taken if you have assembly code that will be called from C or C code called from assembly code, the assembly code will need to be updated to conform to the new calling convention. If in doubt say N
