63c1a05718 * SPARC: Removed hacks with g1_used that were used for g_intf_wrapper to be operational without initialized reg.allocator, and replaced them with a proper solution (which is basically a clone from MIPS cg).

05489d6e05 * SPARC: fixed g_intf_wrapper for non-virtual methods once again, my initial assumption was not correct: a wrapper does not necessarily reference methods from the class that implements the interface, it may be methods from parent classes, which can be located arbitrarily far away in address space. 
Now using code from g_external_wrapper, which has no distance limit and is only one instruction longer.

d2b8275b99 + support for arbitrary encodings in readstr/writestr 
o set the code page of the temporary "text" file to utf-8 for writestr with
     unicodestring/widestring as destination, so that no data loss can occur
     (+ properly deal with cases whereby part of an utf-8 character is
      written to the textbuf in this case)
   o explicitly pass the code page of the destination ansistring for writestr
     with ansistring as destination and set it for the temporary "text" file
   o set the code page of the text file for readstr

ddf08b4eb7 * call TranslatePlaceholderCP() when comparing code pages to avoid 
unnecessary conversions between CP_ACP and the current actual
    DefaultSystemCodePage
  * call TranslatePlaceholderCP() when changing the code page of a
    text file because in some cases this code page is passed directly
    to widestringmanager.Wide2AnsiMoveProc() (which does not perform any
    translation itself)

f69a76b5b1 * generate shorter code on 8-bit and 16-bit CPUs in thlcg2ll.location_force_reg, 
when converting a LOC_JUMP location to a (OS_INT<x<=32)-bit reg location
  (the optimization is similar to r26314, but is for non 64-bit destinations).

9ec84d1259 * generate shorter code on 8 and 16-bit CPUs in thlcg2ll.location_force_reg, 
when converting a LOC_JUMP location to a 64-bit reg location by only setting
  the low OS_INT-sized register to 0 or 1 in the false/true label parts and then
  initializing the remaining registers (obtainable via GetNextReg()) to 0 in the
  common part after the jumps.

6d48b32115 * fixes and improvements in tcg8086.a_load_reg_reg for the case when the src and 
dest are subregisters of the same superregister, but of different sizes:
   o Do not emit spurious moves from a register to the same register.
   o Correctly support the case when converting from 16-bit to 32-bit int.
     Previously it didn't work correctly, because in this particular case, due
     to the way the GetNextReg scheme works, we have reg1=reg2.

4e795eca99 * fixes for 16 and 8-bit ALUs in thlcg2ll.location_force_reg for the cases when

  This fixes test/cg/tcnvint1.pp on i8086 after r26301.

176d8434e4 * SPARC: completely rewrote PIC-related code, got it twice shorter in source lines and much less instructions in generated code. 
+ Enable registers %i0..%i5 and %o7 for use by reg.allocator.

Some notable properties of this implementation are:
  o pi_needs_got flag can be safely set during pass 2, so not setting it occasionally in pass 1 does not result in internal error.
  o Reg.allocator configuration is independent from PIC. If procedure requires GOT, register %l7 is allocated at the prologue, making it unavailable to RA.
  o GOT is stored in fixed %l7 register, but it is trivial to switch over to virtual register.

eaba90dda7 * SPARC: since peephole optimizer recognizes only one conditional branching instruction, generate all branches using A_Bxx opcode, and change it to A_FBxx if necessary when writing assembler. This enables optimization of floating-point branches. 
* Assembler reader: rewrote branch condition matching part, don't try to match integer suffixes to floating-point branches and vice versa.

03fb83cc01 * SPARC: fixed PIC interface wrappers for non-virtual methods. The fix uses branching with 8 MB distance limit, but in particular case of interface wrappers this limit applies to code size of a single unit, not to entire program, and is therefore hard enough to reach.

af49e50a3c * do not cause an internal error when location_reg2string is called on a 
location where the registers have been translated (i.e. not imaginary), but
  GetNextReg is necessary to get some of the registers (only on 16/8-bit CPUs).
  The missing registers are indicated as '??'. This avoids a crash when
  compiling a system unit on i8086 with regvars enabled and withous -sr, while
  still giving the full list of registers when compiling with -sr.
