53052f26a0 * changed output parameter of process_ea_ref() from "out" to "var", as it is 
already partially initialised by its caller (part of mantis #29439)

db5e67c3fe + introduced a new type TRelocDataInt for use as the 'data' parameter for 
TObjData.writeReloc; on i8086 it was changed to longint to allow using 32-bit
  relocations
+ added support for writing 32-bit OMF relocations

ef9504ffd7 * made the \325 x86 prefix to generate a 0x66 prefix on i8086, thus fixing many 
32-bit instructions on i8086, when using the internal obj writer

e6ac1a4af5 + added check for the compatibility of each instruction with the selected target

e877bae4fc + add 'jmp rm16' and 'call rm16' before the rm32 versions on i8086, so the 
16-bit version is picked up by default for opsize=S_NO. Previously the 386
  version was picked on i8086, but the generated code was correct, because we
  don't yet generate a 0x66 prefix for "\325", which leads to many 32-bit
  instructions not being assembled correctly with the internal asm obj writer on
  the i8086

a508f9e5d3 + added check if the selected cpu is 386+ when writing a 66h or 67h prefix in 
the i8086 internal object writer. This allows weeding out spurious 386
  instructions, as is similarly done by NASM when using it as an external
  assembler.

21c9712ea2 * allow 32-bit operand sizes in the i8086 version of Tx86Operand.SetSize, so 
32-bit operands can work properly in i8086's inline asm. Fixes mantis #29188.

f69f6336e9 * Replaced hacks with resetting 'c' to zero and decreasing inputpointer by boolean parameter to skipcomment and skipoldtpcomment. This parameter specifies whether first character of comment should be read. 
- in_asm_string also rendered useless by r32828, removed.

bbfbab7e0c * Moved handling of comments and line breaks in assembler blocks from scanner to tokenizer level. Handling them at character level was causing compiler to accept comments in the middle of any assembler token, which should never happen. It was also causing Mantis #27459: a newline immediately after closing 'end' token was first handled in asmgetchar and then by normal parser, causing all subsequent line numbering to be off by one.

1b965e6766 * x86: Don't save/restore integer registers that are volatile per calling convention of current procedure. It implies that nothing will be saved for procedures with OLDFPCCALL, FAR16 and PASCAL and calling conventions. OLDFPCCALL restores behavior that was in effect before r25224.

78362ed6ae * RELOC_ABSOLUTE32 made different than RELOC_ABSOLUTE on i8086 (and fixed all 
the i8086 bugs, related to code that assumes that they are the same)
+ also added RELOC_RELATIVE32 on i8086
* RELOC_ABSOLUTE32 and RELOC_RELATIVE32 are not yet implemented in the OMF
  object writer and linker (and currently produce an internal error), but will
  be implemented in the future, as the OMF format supports both 16-bit and
  32-bit relocations

a553b15a1c + handle properly inline asm segment constants different than word: 
o 'DB SEG symbol' produces an error
  o 'DD SEG symbol' (and anything larger than DW, like DQ) adds extra high zeros
    to the segment constant (this is Turbo Pascal 7 compatible)

2e30b92c79 * removed the 'near ignored' and 'far ignored' inline asm warning messages on 
the i8086, as 'near' and 'far' actually work there. Some forms may even work
  on the i386, but that's not tested very well for now, so we leave the messages
  there on i386 and x86_64.
