Хм. Это уже второе эмоциональное письмо, но при этом совсем не ясно: А
чем вас так смущает этот флаг?
info gcc:
`-fomit-frame-pointer'
Don't keep the frame pointer in a register for functions that
don't need one. This avoids the instructions to save, set up and
restore frame pointers; it also makes an extra register available
in many functions. *It also makes debugging impossible on some
machines.*
On some machines, such as the VAX, this flag has no effect, because
the standard calling sequence automatically handles the frame
pointer and nothing is saved by pretending it doesn't exist. The
machine-description macro `FRAME_POINTER_REQUIRED' controls
whether a target machine supports this flag. *Note Register
Usage: (gccint)Registers.
Enabled at levels `-O', `-O2', `-O3', `-Os'.
Надо заметить, что для x86 этот флаг иммет смысл, так как он не включён
на уровнях -O* так как влияет на отладку. Поэтому если хотите делать с
дебугером поиграть, то нужно убрать файл. Во всех остальных случаях это
даёт небольшой прирост в производительности.
Peter.
