This applies to FRV options, which is a specific processor, so it's not 
available for your architecture.

cc1: error: unrecognized command line option "-mfdpic"

2009-06-24 Thread Jin Guojun 

This option "-mfdpic" is shown in manual page for gcc 4.1 or later

  -mfdpic
  Select the FDPIC ABI, that uses function descriptors to represent
  pointers to functions.  Without any PIC/PIE-related options, it
  implies -fPIE.  With -fpic or -fpie, it assumes GOT entries and
  small data are within a 12-bit range from the GOT base address;
  with -fPIC or -fPIE, GOT offsets are computed with 32 bits.  
With a

  bfin-elf target, this option implies -msim.

However, tried all gcc 4.1.x, 4.2.x and 4.3.x with following test, and 
no one of them accept this

option:

%: echo "#include " | gcc43 -mfdpic - -E
cc1: error: unrecognized command line option "-mfdpic"
# 1 ""

%: echo "#include " | gcc43 -fdpic - -E
cc1: error: unrecognized command line option "-fdpic"
# 1 ""

where "-dpic" option is a voild option.
Does anyone know why "-mfdpic" option is missing from gcc4.x in FreeBSD 
distribution?

Is this due to some license issues?
If so, what is the other option to subtitute it?

Thanks,
-Jin
