27a7c0863b + added constructors tai_const.Create_int_codeptr and .Create_int_dataptr. To be 
used for emitting magic consts with the size of a code or data pointer (used
  in e.g. rtti data).

b70c5efa65 * SPARC peephole: check that result of GetNextInstructionUsingReg is actually an instruction, because GetNextInstruction can stop at a label. Resolves #26798. 
The same issue on MIPS targets was fixed by r28380, but I forgot to apply it also to SPARC.

a3c439c60f - No longer insert BlockStart markers into asmlists. The presence of these markers disrupts peephole optimizations and require additional checks all over the place, causing various workarounds/hacks (like TAsmList.Create_without_marker) to start building up. 
A more radical approach is to remove them altogether. Tested with i386-win32 (the oldest peephole optimizer), mips-linux (the newest one) and arm-linux (the most complex one) targets. The fallout was limited to two minor issues fixed in r28629 and r28708, respectively.

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).

0b4d54fcb9 - Delete all position markers from assembler code before optimization. Markers of this kind are not used by optimizer and are expected to be ignored, but ignoring them requires numerous checks in all target-specific optimizers and currently isn't done correctly. In turn, failure to ignore markers prevents optimization of procedure prologues and epilogues.
