; Generated from the following source. f4 is used to put a hole in the CU
|
|
; ranges while keeping f2 and f4 in the same section (as opposed to
|
|
; -ffunction-sections, which would produce CU ranges, but each function would
|
|
; be in a different section, so unable to share addresses). The call to f1 at
|
|
; the start of f3 ensures the range for the inlined subroutine doesn't share
|
|
; the starting address with f3 (so it can be improved by using a rnglist to
|
|
; allow it to share an address it wouldn't already be sharing).
|
|
|
|
; Without f6 being in another section, technically we could use a non-zero CU
|
|
; low_pc that could act as a base address for all the addresses in the CU & avoid
|
|
; the need for these forced rnglists - we don't do that currently, but f6 ensures
|
|
; that this test will remain meaningful even if that improvement is made in the
|
|
; future. (implementing that would require detecting that all the addresses in
|
|
; the CU ranges are in the same section, then picking the lowest such address as
|
|
; the base address to make all other addresses relative to)
