3f19bd693f + Add new LastCommonAsmOp constant to arm and aarch64 CPU targets.
* Uses this new constant to define TCommonAsmOps set type.
  + Use this constant in armgen/aoptarm MatchInstruction function,
    to avoid a range check error when compiling with -CriotR with optimization.

69786ffe73 somehow committing went wrong, second part of last commit:
+ AArch64: support for vX.8b/vX.16b register names
+ support for more than 256 registers in the register dat files
- removed totherregisterset
+ AArch64: use vmov to load immediates if possible
+ AArch64: use eor to clear mm registers

518cdf9674 * replaced the saved_XXX_registers arrays with virtual methods inside

d023c63ad0 Add a lot of instruction table entries and missing instructions for support of most ARM32 mode instructions from ARMv4 up ARMv7A.
Add some VFP registers.
Rebuilt tables.
Added a lot of VFPv3 and Advanced SIMD(not supported yet) oppostfixes.
Implemented code in aasmcpu to generate binary code from the instructions. Only ARM32 supported so far.

c48d572996 Implement support for saving and restoring address registers.
cgobj.pas, tcg:
  * g_save_registers: add the amount of used address registers to size as well
  * g_save_registers: save all used address registers
  * g_restore_registers: restore all stored address registers
m68k/cpubase.pas:
  * rename saved_standard_address_registers to saved_address_registers
all other platform's cpubase.{inc,pas} (except alpha, ia64 and vis which are not up to date):
  * add a saved_address_registers variable with one entry of RS_INVALID

At least a "make fullcycle" did complete.

e327b4581c Use TRegNameTable instead of array[tregisterindex] of string[10]
TRegNameTable is defined in compiler/rgbase.pas and is an array of
strings, limited to the maximum length of the used register names.

r22792 added a long register name but did not scale the string-size
enough, resulting in the compiler built breaking for arm.

54d3d736f5 * patch by Jeppe Johansen to add support for handling different flags for xPSR regs,
and add usermode parsing of LDM/STM ops
  This patch basically extends the ARM assembly reader a bit to properly parse CPSR and 
  SPSR flags for the MSR opcode, and allows the reader to understand 
  the ^ modifer for register lists for STMxx and LDMxx.

  Previously the following combinations weren't possible in straight assembler:
     MRS R0, CPSR
     MRS R0, SPSR
     MSR CPSR_CX, R0
     LDMIA SP, {R0-R15}^
     etc..

aa2a9dbf2e patches by Nico Erfurth to improve the arm peephole optimizer:
* Introduce MatchInstruction and MatchOperand

MatchInstruction allows to match an instruction by condition and
oppostfix. MatchOperand checks if an operand is a register and matches
another operand. In the future this could be overloaded with other
versions not only accepting TRegister.

* Optimize cmp,moveq,movne sequence on ARM

This patch implements an peephole optimizer for the following sequence:

  cmp   reg,const1
  movne reg,const2
  moveq reg,const1

* Small improvements to the ARM peephole optimizer

Most instructions in the ARM ISA have taicpu(p).oper[0]^.typ = top_reg
as the only option, so there is no need to check for it if we're
looking at those instructions.

* Remove redundant mov instructions on ARM

This is an addition to the ARM PeepHole Optimizer.
It folds code like this:

mov reg1, reg2
add reg1, reg1, (const|reg)

bba4b02eb2 * use r7 instead of r11 as frame pointer on Darwin/iOS, and make sure r7
always points to the previous r7 on the stack (with the saved return
    address coming right after it) so that the debugger and crashreporter
    can use it for backtraces as specified in the ABI
   o changed NR_FRAME_POINTER_REG and RS_FRAME_POINTER_REG from a symbolic
     into a typed constant, and added a new method to tprocinfo that can
     be used to initialze it (so it can be inited to r7/r11 depending on
     the target platform)
  * allow using r9 on Darwin, it was only used by the system on iOS up to
    2.x, which we no longer support
  * prefer using r9 and r12 before r4..r11 on Darwin, because they are
    volatile and hence do not have to be saved
