Hi, GCC experts:
I am playing with C, and have tried the -freorder-functions with
__attribute__((hot)), it works some but the link only reorder the
functions that in one object file range , Is there any way to ask link
to reorder the functions in whole executive file range?
Can I name the functions (C code) to other code segments (instead
of .text by default)?
Thanks & Best Regards,
Shaolin

If you are using the gold linker you can use the --section-ordering-file
option. You should use -ffunction-sections to give each function its
own section.

Sure. See __attribute__ ((section (xxx))).
See also gcc's -freorder-blocks-and-partition option.
