d72478eb64 * Function tjvmaddnode.cmpnode2topcmp is, in fact, not specific to any target. Moved it to generic tcgaddnode and reused in tmipsaddnode, where the same functionality was implemented in different way.

e16e19b170 * MIPS: removed specific handling of 32-bit shifts, generic code does the job just well. 
* Tweak 64-bit shifts to take advantage of 3-address instructions (i.e. don't operate on same register).

2a112ad01b * MIPS: don't optimize reference twice for 64-bit loads and stores. Now loading/storing 64-bit value to global variable takes typically 3 instructions.

6fdadb6248 * 8087 fixes in tx86addnode.second_cmpfloat: 
- use FSTSW instead of FNSTSW
  - insert a FWAIT after the FSTSW, because the value is immediately loaded
    afterwards by the integer unit of the CPU

0020a2ed10 + when targeting the i8087, emit FWAIT prefix manually for the 8087 instructions

3ce0b33302 * Win64 SEH: when creating a finalization procedure, put its def into the same symtable with sym. By default, defs are added into symtablestack.top, which may be set to something temporary like exceptsymtable. In such cases it is possible that def is destroyed before sym, leaving sym with invalid pointers.

dc432918da + enabled the use of the DIV/IDIV instruction for 16-bit div/mod on i8086 
* ti8086.moddivnode.pass_generate_code: use cg.a_op_const_reg, instead of
  emit_const_reg, in order to support generating plain 8086/8088 code
  (shr/shl/sar reg,const is 186+ if const is >= 2).

bd083c0b8e * ti8086moddivnode.pass_generate_code converted to 16-bit. Note that this code

c1cec52897 * fixed alignment of bitpacked arrays of ordinals/enums: the prevous code 
always returned the alignment of enum/ordinal by itself, which could be
    either bigger or smaller than what was required
  * for non-bitpacked regular arrays, always use the alignment of the elements
    instead of sometimes the natural alignment of the size of the elements
    (which can be different)

f348e89112 - removed too early assignment of have_first_symbol:=true, making the later
