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

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
