d6de2c03cb * generic part of r26050 from the hlcgllvm branch: made tcgvecnode hlcg-safe 
o in particular, add tdef size information to the update_reference*()
     methods, and factored out offset adjustments into its own method
   o also make sure the passed size to update_reference*() corresponds to the
     actual size of the index, as it's no longer guaranteed to be ptruint
     since the previous commit

fdb09365ba m68k: instead of trying to mess with LOC_FLAGS, use LOC_REGISTER to return a boolean result of the compare. idea by Florian. fixes several issues with optimizer enabled and also results in better code in some cases.

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.

5c67fcc43f + change always floating point divisions into multiplications if they are a power of two, 
this is an exact operation so it is always allowed

aa6b62cf4c Add new procedure option: po_syscall_has_libsym, 
include this option only of libsym field
 is non NIL.
 Use this option to only write redef of libsym if needed.
 Adapt ppudump source to this new procedure option.

9b0bf91076 m68k: do not generate CLR instructions to memory references on plain 68k. there this instruction also causes reads from the address, which is slow and can have side effects.

a28d6a84a7 + m68k, a_load_const_reg: use MOV3Q if applicable for data registers as well, since it allows spilling replacement of destination. 
+ a_load_const_ref: use CLR and MOV3Q if possible.
* a_cmp_reg_reg_label: force size to 32 bits for ISA_A and ISA_A+ targets.
+ support for stack frames larger than 32767 bytes.

3da5de0e5f + m68k, do_spill_replace: support more cases.

bd5ce35130 * m68k: completely replaced 64-bit comparison code with a clone of i386 implementation. No optimizations yet, but it already makes system unit about 300 instructions shorter due to changing node location to LOC_JUMP. 
* Cleaned up 32-bit comparison code and implemented one of the optimizations (TST instruction for comparison with constant zero which can act directly on references). This makes system unit shorter by about 1000 instructions.

dac52f503c * m68k: fixed extension in a_load_ref_reg. Existing code cleans only bits 16-31 when loading a 8-bit register from 16-bit reference, and leaves garbage in bits 8-15.

b7da785688 * m68k: support stack cleanup at caller side, fixed calculation of pushed parameters size and offsets and cleaned out another pile of junk. 
* Parameter offsets are now calculated similar to other targets, target_info,first_parm_offset is applied only to callee side, while at caller side offsets start from 0.
* For cdecl procedures, parameters are removed by caller, for the rest it's still done by callee (resembles i386 target, except there is no 'register' calling convention).

cfe13734e0 * m68k: Fixed damage caused by r27573 and r28177: 
* longjmp: restored loading of function result (d0) which got removed in r28177.
  * While at the point, added test for zero, because longjmp must never return zero values.
  * Assembler reader: 'fp' refers to frame pointer, not the stack pointer.

b91d965096 * m68k: initial support for ROL/ROR operations, defining 'cpurox' for CPU target can actually enable them. However it cannot be done outright because these instructions do not exits on Coldfire, and internal processing of RoX,Sar,BsX, etc. can not yet be switched depending on CPU subtype.
