@sebpop, @vsk or @hiraditya can probably answer this. I'm not working on the core hot cold splitting algorithm, just some issues I'm finding as I try it. But presumably the linker should be grouping the split hot functions together and the split cold functions together, when building with -ffunction-sections and PGO which should put them in the .text.hot and .text.unlikely sections, respectively.
