-Attempt to attach bitcode stuff on MacOS using ld:
-
- ld -r <file.o> -sectcreate __LLVM __llvm_bc <tmpfile> -o <file.o>
-
-This works (it adds a new section called __llvm_bc in a new __LLVM
-segment), but the 'ld -r' part may have bad side effects. For example
-if the <file.o> is produced with -fvisibility=hidden then calling
-ld -r <file.o> converts the extern symbols into local symbols.
-
-Workaround for now: give a warning if we see -fvisibility=hidden on
-the Mac.

-TODO: extract-bc for MacOS
-
-To extract bitcode from binaries, objects, or library files on Darwin:
-
-  otool -X -s __LLVM __llvm_bc yices_sat | xxd -r 
-
-Explanations:
-
-  otool -s __LLVM __llvm_bc file  extracts and display the section we care about
-
-  flag -X removes some useless headers we don't want
-
-  xxd -r converts the hexdump to ASCII list of file names
