3fee990218 * on Mach-O, PECOFF and ELF platforms, write local symbols as hidden/ 
private_extern (or plain global in case of PECOFF, as the effect is
    the same there): visible across object files, but they become local
    when linked into a binary/library. This enables cross-unit inlining
    of functions accessig implementation-only symbols.

1ed0000ae8 + Encode(U/S)leb128 take now a third parameter to force that the constant has a certain minimum size 
+ tai_const has a new field fixed_size which is used to fix the size of an s/uleb128. This is needed to ensure convergence during assembling when calculating offsets

4e51dc2298 m68k: enable named sections for vasm generated objects. have a separate as_m68k_as_aout for a.out objects which doesn't have named sections. amiga and atari gas defaults to a.out, so have it default on these systems. finally enable section smartlinking for amiga and atari, which will be used with vasm assembler

5ac99f62e9 + AT_METADATA symbol type for data that is unrelated to the program

178dab45d3 + added new asm directive 'asd_cpu' (specifies the CPU's instruction set) in the 
compiler's internal assembly representation. It is not yet generated by the
  compiler and is only implemented properly in the NASM writer (but will
  eventually be implemented in the other assembler writers as well, including
  the internal assembler). In the future, it is intended to allow:
  1) catching instructions, generated by the compiler and not supported by the
     target CPU, due to a bug in the code generator
  2) allowing a different instruction set to be used in inline asm blocks (I'm
     planning a new directive for that - {$asmcpu XXX}), because the code
     generator will be able to switch target CPU in the middle of the asm output
     stream

61c0448903 * Big fix for ARM GOT support to make it work: 
- Fixed access to symbols with offset.
  - Always use register R9 for GOT pointer to prevent bugs when free register limit is reached in a function.
  - GOT is not needed for function calls by name.

991e1f49bd * store a pointer to the used tasminfo record in every assembler writer, so 
that we can use assembler writers with different conventions from the

    in LLVM IR)

fb27dff638 * generate ".abiversion 2" directive when targeting ppc64/ELFv2 
* generate code to load the TOC register if it's required, and
    emit the the ".localentry" directive to indicate to the linker
    where the actual function body starts
  * support the ".localentry" directive in the ppc64 assembler reader
   o disable the fpc_qword_to_double() assembler implementation for
     ELFv2, because we can't manually insert the .localentry directive
     before the stack allocation code
  * perform indirect calls on ppc64 via R12 in ncgcal, as R12 needs to
    contain the function address on entry on ppc64/ELFv2 (and it's
    a volatile register, so there's no problem with always using
    it)
