e6a9bfdc1d * SPARC, g_concatcopy and g_concatcopy_unaligned: removed strange (probably long outdated) comments and unnecessary operations. 
* g_concatcopy: avoid taking address of references if possible.

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.

8ecad469a6 * Reverted r26256 since it produced wrong results if argument of inc/dec is actually unaligned. Added description of the issue and slightly increased node complexity at which address is cached, so operations on record/class fields do not take address.

5cd0684d45 * tcg.a_load_ref_reg_unaligned: if loading signed 16-bit value, treat upper half as signed 8-bit to ensure that result is properly extended. This routine is used only by SPARC target (other CPUs use specific implementations), and it generates pretty inefficient code, therefore it's probably worth to drop it altogether and implement SPARC-specific version. Mantis #25440.

allow escaping delimiters by doubling them e.g.

  which gives
  (NAME='O''Malley''s "Magic" Hammer')
  which will match record
  O'Malley's "Magic" Hammer

74f9d719f1 * i386-win32 setjmp and longjmp: if SEH support is enabled, save/restore head of exception registration chain. Without this, a longjmp out of a function with exception frame(s) will leave these exception frames below ESP, which will fail integrity checks in OS and cause process termination if an exception occurs later on (or they may be overwritten by subsequent operations on stack and, again, cause undesired results). 
* Additionally, use a branchless sequence to fix up result of longjmp.
