Use small code model for UEFI targets * Since the code model only applies to the code and not the data and the code model only applies to functions you call through using `call`, `jmp` and data with `lea`, etc… If you are calling functions using the function pointers from the UEFI structures the code model does not apply in that case. It’s just related to the address space size of your own binary. Since UEFI (uefi is all relocatable) uses relocatable PEs (relocatable code does not care about the code model) so, we use the small code model here. * Since applications don't usually take gigabytes of memory, setting the target to use the small code model should result in better codegen (comparable with majority of other targets). Large code models are also known for generating horrible code, for example 16 bytes of code to load a single 8-byte value. Signed-off-by: Andy-Python-Programmer <andypythonappdeveloper@gmail.com> |

specific to different compilation targets and so forth.
