-Unimplemented Features

-Unimplemented Relocations
-#########################
-
-All of these relocations are defined in:
-http://www.x86-64.org/documentation/abi.pdf
-
-Trivial Relocs
-<<<<<<<<<<<<<<
-
-These are very simple relocation calculations to implement.
-See lib/ReaderWriter/ELF/X86_64/X86_64RelocationHandler.cpp
-
-* R_X86_64_8
-* R_X86_64_PC8
-* R_X86_64_SIZE32
-* R_X86_64_SIZE64
-* R_X86_64_GOTPC32 (this relocation requires there to be a __GLOBAL_OFFSET_TABLE__)
-
-Global Offset Table Relocs
-<<<<<<<<<<<<<<<<<<<<<<<<<<
-
-* R_X86_64_GOTOFF32
-* R_X86_64_GOTOFF64
-
-Global Dynamic Thread Local Storage Relocs
-<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
-
-These relocations take more effort to implement, but some of them are done.
-Their implementation lives in lib/ReaderWriter/ELF/X86_64/{X86_64RelocationPass.cpp,X86_64RelocationHandler.cpp}.
-
-Documentation on these relocations can be found in:
-http://www.akkadia.org/drepper/tls.pdf
-http://www.fsfla.org/~lxoliva/writeups/TLS/RFC-TLSDESC-x86.txt
-
-* R_X86_64_GOTPC32_TLSDESC

- In general the linker scripts's GROUP command works like a pair
- of command line options --start-group/--end-group. But there is
- a difference in the files look up algorithm.
-
- The --start-group/--end-group commands use a trivial approach:
- a) If the path has '-l' prefix, add 'lib' prefix and '.a'/'.so'
- suffix and search the path through library search directories.
- b) Otherwise, use the path 'as-is'.
-
- The GROUP command implements more compicated approach:
- a) If the path has '-l' prefix, add 'lib' prefix and '.a'/'.so'
- suffix and search the path through library search directories.
- b) If the path does not have '-l' prefix, and sysroot is configured,
- and the path starts with the / character, and the script being
- processed is located inside the sysroot, search the path under
- the sysroot. Otherwise, try to open the path in the current
- directory. If it is not found, search through library search
- directories.
