Should I declare these functions as weak in the core i386 code and use a config #define to override or should I seperate the functions out into seperate source files and use conditional compilation?
i wonder if weak functions that are always satisfied and used unconditionally result in larger code, or if this is only a problem for people whose linkers lack lazy relaxation support ?
It's probably a problem with linkers that don't support --gc-sections, which is different from relaxation. Also, you definitely need to compile with -ffunction-sections, or the weak functions might end up in the same section as something linked unconditionally, which makes it impossible for the linker to remove them.
