[LLVMdev] DragonEgg on FreeBSD

[陳韋任]

Hi, Duncan

  I only tested dragonegg on simple HelloWorld C/C++ programs. It can emit LLVM IR and
generate a runable executable.

  On FreeBSD, Makefile need to be modified to include a path to gmp.h
header file. I give a patch here,

  And you should make a freebsd directory and copy linux/llvm-os.h to
there.

--------------------------------------------------------------------------------
$ mkdir freebsd
$ cp linux/llvm-os.h freebsd/
--------------------------------------------------------------------------------

  Finally, use "gmake" not "make" on FreeBSD to build dragonegg.so.

  Well, there are warings while building dragonegg.so. But I guess it
doesn't affect dragonegg.so, I just leave it there. Here are the
warnings.

--------------------------------------------------------------------------------
<command-line>: warning: "__STDC_LIMIT_MACROS" redefined
<command-line>: warning: this is the location of the previous definition
--------------------------------------------------------------------------------
