Right; Haswell are the 4xxxx , Broadwell  5xxxx then you must select for broadwell or for "native" (with native gcc will load the cpu instructions; sometimes with new stepping could be enabled other instruction:

for example the 4770K is unlock; the 4771 is locked (not overclockable but with a coouple of instruction for virtualization or power consumption.) So .... I'm for the use of "native".

I use the -march=native in my make.conf and also for the kernel.

# euse -E experimental -p sys-kernel/gentoo-sources
# emerge gentoo-sources 

Then in "processor types & features" there will be the option to choice Processor family; 

You can select broadwell or "native".

 

The USE flag "experimental" enabled for gentoo-sources will give to you to select also the BFQ Scheduler.
