X86-64: Difference between revisions
-mcmodel=kernel affects codegen. Using a linker script has nothing to do with codegen, since only the linker looks at the script, not the compiler. Recommending not to use it, is just plain wrong.

It worth noting that code models are different for architectures, as they are tied with the instruction encoding. For example, AArch64 has a "-mcmodel=tiny" too, which allows 1M addressing, unknown to x86_64. And for AArch64 "-mcmodel=small" has a 4G limitation, not 2G as for the x86_64.
