compiling options


  I have seen some options that are default in eCos while compiling for
which I can't find documentation. these are:
-fdata-sections
-fno-rtti
-fno-exceptions
-fvtable-gc
-finit-priority
-Wl,--gc-sections

  Can somebody tell me what are they for or where is the documentation
about those?

  I have also read that ffunction-sections is used but I don't
understand why. It seems to generate worse code, which is its advantage?
