4d41decd5d * since m68k has a working implementation for the register calling convention and it's in fact used as default calling convention it should also be possible to explicitely declare routines as that calling convention

a25ebbba3e + added volatility information to all memory references 
o separate information for reading and writing, because e.g. in a
     try-block, only the writes to local variables and parameters are
     volatile (they have to be committed immediately in case the next
     instruction causes an exception)
   o for now, only references to absolute memory addresses are marked
     as volatile
   o the volatily information is (should be) properly maintained throughout
     all code generators for all archictures with this patch
   o no optimizers or other compiler infrastructure uses the volatility
     information yet
   o this functionality is not (yet) exposed at the language level, it
     is only for internal code generator use right now

bbfbab7e0c * Moved handling of comments and line breaks in assembler blocks from scanner to tokenizer level. Handling them at character level was causing compiler to accept comments in the middle of any assembler token, which should never happen. It was also causing Mantis #27459: a newline immediately after closing 'end' token was first handled in asmgetchar and then by normal parser, causing all subsequent line numbering to be off by one.

fa3b0ca312 * support marking defs created via the getreusable*() class methods as 
"don't free even if not registered"; use for defs that may not be written
    to a ppu file, but that must nevertheless survive the compilation of the
    current module
  * mark all defs created for para locations as "don't free even if not
    registered", because we don't discard and recalculate all para locations
    after a module has been compiled (since that's not needed)
   o solves issues if the paralocations for a routine in the interface of
     unit A are calculated while the implementation of unit B gets
     compiled, and a new reusable type is allocated at that point which
     is not used anywhere else (after r32160)
