History
sergei 06192a8137 Values of managed variables are never ever used after decrementing reference on the variable, so there is no point of having a 'decrement reference' as a separate operation. We can always do 'finalize', i.e. clear the contents after decref. 
* Modified fpc_ansistr_decr_ref and fpc_widestr_decr_ref so they always zero the pointer passed by reference. Other _decr_ref helpers already do it.
- Removed tcg.g_decrrefcount, calling cg.g_finalize instead.
- finalize_data_node and tcg.g_finalize: removed code generation for zeroing locations, because it is now done by RTL helpers. This further reduces code size.

As a total result of this change and r20118, the size of Lazarus executable is reduced by about 12%.

readme 

This directory contains only RTL parts specific to the processor I386 family.

(They are specific because they contain assembler instructions)

Include files for system are :
  heap.inc (heap handling)
  set.inc  (sets operations)
  math.inc (mathematic operations using the coprocessor)
  i386.inc (several functions/procedures containing assembler parts)
  setjump.inc (setjmp/longjmp implementation for exceptions)
  rttip.inc (rtti handling, for speed reasons)
  
Units are :
  strings.pp (written in assembler for speed)
  cpu.pp     (routines to access cpu info)
  mmx.pp     (special mmx routines)
