fe322f35d5 * MIPS: fixed passing CPU type specified with -CpXXX switch to assembler 
- removed mips_cpu variable and cpu_mips_default CPU type.
  * globals.pas: default CPU type changed to MIPS2, this is what was passed to assembler before.

0ad96d2099 * MIPS: some clean up of assembler reader:

2944fc8839 * MIPS improvements: 
* reworked condition codes, changed BC1T and BC1F from separate instructions to condition jumps.
  - removed A_P_SW, A_P_LW and A_SPARC8UNIMP

956b26bc97 Completely reworked implementation of generic constraints, by moving the generic constraint data from the symbols to the definitions (I originally thought that this would simplyfy things, but the more correct approach is to add it to the defs). 
symsym.pas:
    - remove "tgenericconstraintdata" and any using/loading/writing of it in "ttypesym"
    - remove "tgenericconstraintflag"
symdef.pas:
    + add "tgenericconstraintdata"
    + load and write "genconstraintdata" in "tstoreddef"
symconst.pas:
    + add "tgenericconstraintflag" so it can be used in "ppudump" as well
defcmp.pas, compare_defs_ext:
    * as we allow global operator overloads we can't really determine whether two defs are compatible, because a valid operator for the specialization types might just happen to be in scope of the generic; so for now constraints are only strictly checked when declaring a specialization
pgenutil.pas:
    * adjust "parse_generic_parameters" and "check_generic_constraints" to the new location of the constraint data
ppudump.pp:
    * corrrectly parse defs which contain generic constraints

cc5a108cca Allocate the list for generic parameters in tstoreddef only on demand as most defs won't contain generic parameters anyway (avoids a little bit of runtime and memory overhead per def). 
symdef.pas, tstoreddef:
  + comment that the list is allocated on demand (and thus should be checked for Nil)
  + fillgenericparas: create the list when adding at least one generic parameter symbol
  - create & ppuload: don't create list instance anymore
  + is_generic & is_specialization: check whether the list is assigned
defcmp.pas, compare_defs_ext:
  + check whether "genericparas" list is assigned
pgenutil.pas:
  + check_generic_constraints: check whether "genericparas" is assigned
  + insert_generic_parameter_types: create list before adding generic parameters

23cb216435 * RTTI fix for alignment-sensitive targets: 
* typinfo.pp: the newly introduced records were added into {$PACKRECORDS 1} area of effect, which  effectively made all records packed, entirely defeating FPC_REQUIRES_PROPER_ALIGNMENT purpose. 
  * added alignment between TProcedureParam records, adjusted TProcedureSignature.GetParam() appropriately.
   * ncgrtti.pas: added two missing alignments and removed a redundant one.
   * tests/test/trtti9.pp: modified to use TProcedureSignature.GetParam() and endian-independent check for parameter flags.

f1f89c77c3 Finally refactor "b_needs_init_final" flag to be a symtable flag which is written to/loaded from the PPU (as discussed in the thread "Status report for "class helpers"" in fpc-devel on 29th January 2011). 
symconst.pas:
    + add "sto_needs_init_final" value to "tsymtableoptions"
symtable.pas:
    - TStoredSymtable: remove "b_needs_init_final"
    + TStoredSymtable: add "init_final_check_done" (which is False by default)
    * TStoredSymtable.ppuload: set "init_final_check_done" to True if PPU is loaded (because the flag will then already be restored)
    * TStoredSymtable.needs_init_final: check the symbols only if "init_final_check_done" is not set yet
    * TStoredSymtable._needs_init_final: only check the symbol if "sto_needs_init_final" is not set yet and set the flag accordingly if needed
utils/ppuutils/ppudump.pp:
    * respect the new flag

fe04dedbab compiler: change RTTI size of record field offset from fixed 32bit to platform dependent integer (sizeint) since it is stored this way in the compiler. This is also Delphi compatible, rtl: adopt rtl appropriately

dce960c97b compiler: write Delphi compatible tkArray RTTI: 
- TotalSize of all array dimensions instead of first dimension size
  - Element type of last array dimension
  - dimension information
rtl:
  - adopt array initialization/finalization/copy for the new tkArray RTTI
  - add Delphi compatible TArrayTypeData member for typinfo.TTypeData structure
tests:
  - add a test which checks RTTI information for 2 dimension array

7cfc737866 * MIPS: rewrote 32-bit code generation methods, reducing code duplication. 
+ Implemented overflow checking for unsigned 32-bit addition and subtraction.
* Use optimize_op_const instead of custom optimizations.
* Change AND/OR/XOR into ANDI/ORI/XORI if they use immediate operands, and use correct range for these immediate operands, must be 0..65535 unlike -32768..32767 for arithmetic operations.
* Don't treat AND/OR/XOR as macros, no longer necessary.
* Don't treat BEQ/BNE as macros either.
