1b26f5c3a3 - MIPS: removed functions get_fsr and set_fsr from the RTL in case the SoftFPU 
is enabled, because they contain inline assembler, containing FPU code

3362abb30c * Set softfloat_rounding_mode indise SetRoundMode function for all CPUs. 
* SetRoundMode returns previous rounding mode value for all CPUs.

b588b3143a + MIPS: Assembler implementation of FillChar 
* Removed commented out assembler implementations of Inclocked(longint) and Declocked(longint) and replaced them with calls to InterlockedIncrement/Decrement, so they actually do the locking.

f85a8159ef * compiler/mips/cpuinfo.pas: removed "FPU_" prefixes from FPU names, not necessary because compiler inserts one itself. 
* rtl/embedded/system.pp: removed (commented out) FPU initialization from initialization of system unit, was dead code anyway because FPC_HAS_FEATURE_FPU is never defined and "feature FPU" does not exist.
* rtl/mips/*.inc: don't compile FPU instructions if compiling RTL with -CfNONE or -CfSOFT (however, handling these switches for MIPS targets in compiler needs further fixing).

217ab9879c * Enabled internal handling of Abs(longint) for all targets. It has been implemented in cross-platform way ages ago (see tcginlinenode.second_abs_long), but not enabled on MIPS,SPARC and m68k. 
- RTL: removed MIPS,SPARC and m68k-specific implementations of Abs(longint), and marked the generic one as  required for bootstrapping purposes only.

0255eb880e - Removed mathuh.inc files which are identical for all targets (except m68k, see below), their contents moved into math.pp.

404c3efa58 * MIPS: handle get_frame internally, so it sets pi_needs_stackframe flag on current procedure. This makes possible not to force pi_needs_stackframe on every procedure and thus omit saving/restoring $fp register when it is not necessary.

8469741700 + Added additional addr pointer parameter to 
get_caller_frame, get_caller_addr and dump_stack
  with default NIL value to systemh.inc.
  + Added new get_addr function.
  system.inc: Use get_addr and get_frame to call
  HandleErrorAddrFrame instead of HandleErrorFrame
  in several error functions.
  Modify dump_stack to use frame and addr parameters.
  Provide a dummy get_addr function returning nil.
  i386/i386.inc, x86_64./x86_64.inc: Provide real
  implementation of get_addr function.

495a6cfebf Merge of rev21558-59-60 by Foxsen 
21558:
use inherited first_int_to_real to avoid mixing doubles and singles
it fixes the failure of test/cg/taddcurr.pp

21559:
set default round mode to round nearest instead of round to zero
it fix test/cg/taddcurr.pp

21560:
enable softfpu, default first_int_to_real depends on int64_to_float64/32 etc.
It is needed by the patch of r21558
