def4df9791 m68k: fixed a bug, where during during unaligned stores, the base address was preinitalized to a temp address register from the wrong reference, causing havoc

ed13f4d0d1 m68k: add a function to optimize const MUL cases to sequences of shifts + ADD/SUB. mainly for '000 and other low end 68ks with slow/limited MUL capabilities. inactive for now, as it wasn't that extensively tested

aa1be3276f - removed default value of _typ parameter of TAsmData.(Weak)RefAsmSymbol(): 
it was AT_NONE, which is invalid and should never be used
  * explicitly pass the correct value for all calls to those methods elsewhere
    in the compiler

2eeb078f3e m68k: removed obsolete and wrong comment. the '881 extended type is actually 12 bytes during load/store, not 10, which means longword alignment is fine. no functional changes.

1e6e5a1874 m68k: implemented a_load64_reg_ref and a_load64_ref_reg. avoids duplicated reference simplifications in the generated code during 64bit load/store

2b250a1b0a m68k: use a_load_ref_ref in a_load_ref_cgpara instead of a custom loading code which does the same. causes no changes in generated code

88e14dc456 m68k: only extend the dest reg to tosize during reg-reg moves. this removes a large amount of unnecessary sign and zero extensions from the generated code. this was attempted before, but thanks to other fixes it no longer causes testsuite regressions

4287f81b92 m68k: support and use float TResFlags in the rest of the CG. ColdFire FPU now works, and FSxx is no longer generated which is software supported on '060, and doesn't exist on CF. if we still want to support it later, we can add it to cg.g_flags2reg

1e0763e251 m68k: use a_load_const_ref in a_load_const_cgpara to utilize the recently added optimized small const loading here too. this change alone shaves off ~80KB from the compiled FP IDE size...

185ee93312 m68k: if we're loading small (8 bit signed) values into long references, move them through a register (usually with MOVEQ). this is two bytes shorter and also faster on most 68k CPUs

c82328e3fd m68k: implemented tcg68k.check_register_size for future use. use R_SUBNONE for FPU registers, because R_SUBWHOLE will change. use isregoverlap in a_load_reg_reg

b617345e43 m68k: disabled premature MOVEA #0,Ax to SUBA Ax,Ax in the CG, because it breaks with spilling temp replacement and moved it to the optimizer, where it belongs. this fixes some code with potentially heavy address register pressure, like the IDE.

d000b1bc7c m68k: basic 68881 fpu support. probably still broken at umpzillion places, and mostly untested, but at least it builds the RTL and all packages successfully with -Cp68020 -Cf68881 instead of dying with random internalerrors() and now even emits actual FPU opcodes.
