cc3e09ee46 * Handle possible relocation types in assembler reader using a single AS_RELTYPE token, rather than with individual tokens for each case. Since possible relocations are target-dependent, this will allow to support any amount of them without modifying the base tattreader class.

5f6442074a - MIPS,SPARC: removed method ReadSym which is never used. 
- SPARC: also removed PowerPC-style parsing of address type (e.g. foo@hi). SPARC syntax is %hi(foo).

1266491085 o refactored some peephole optimizer code: 
* updated TAOptObj.RegUsedAfterInstruction with the arm implementation and removed the arm specific implementation
  * RegLoadedWithNewValue and InstructionLoadsFromReg are now a methods of TAoptBase
  * moved RegEndOfLife to TAOptObj
* during this refactoring, fixed also TCpuAsmOptimizer.RegLoadedWithNewValue for arm regarding post/preindexed 
  memory references: those modify the register but do not load it with a new value in the sense of RegLoadedWithNewValue

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)

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
    currently set target_asm (e.g. an x86 assembler writer for inline assembly
    in LLVM IR)

b3d0197f98 * factored out the output file handling (mostly writing data) from the 
external assembler writer, so we can reuse the archtecture-specific
    writers to write inline assembly in LLVM IR files

0fc1fd6ac1 * replaced current_procinfo.currtrue/falselabel with storing the true/false 
labels of LOC_JUMP in the node's location. This generates some extra jumps
    for short circuit boolean and/or-expressions if optimizations are off, but
    with optimisations enabled the generated code is the same (except for JVM
    because the jump threading optimisation isn't enabled there yet).

b57c95043f + support overriding tdef/tsym methods with target-specific functionality: 
o made all (non-abstract) tdef and tsym constructors virtual
   o added c*def/c*sym classref types for every (non-abstract) t*def/t*sym
     class
   o added cpusym unit for every architecture that derives a tcpu*def/tcpu*sym
     class from the base classes, and initialises the c*def/c*sym classes with
     them. This is done so that the llvm target will be able to derive from
     the tcpu*def/sym classes without umpteen ifdefs, and it also means that
     the WPO can devirtualise everything because the c* variables are only
     initialised with one class type
   o replaced all t*def/t*sym constructor calls with c*def/c*sym constructor
     calls

c673c32ad9 + SPARC: generate position-independent case jump tables, as specified by ABI.

720b9bf560 * SPARC: reworked 64-bit comparisons so their result is always in flags. Comparisons are emitted as subtractions, sides are optionally swapped to avoid using Z flag (since it is not set correctly in multi-word subtraction). This generates significantly shorter code: when both sides are in registers it is just 3 instructions for equal/unequal and 2 instructions otherwise.
