Better support for segmentation

Description (last modified by peter@…) (diff) 

YASM at the very minimum needs to handle segmentation as well as NASM does. 
This will necessitate adding a true segment field to expression constant values
and making expressions aware of operators like SEG.

Added very preliminary support for :, SEG, and WRT operators to expr.

comment:3 Changed 8 years ago by peter@…

  • Severity changed from enhancement to major 
This also includes call/jmp far imm.  Upping severity as this MUST be fixed.

comment:4 Changed 7 years ago by peter@…

  • Status changed from new to assigned
  • target_milestone changed from 0.2.0 to 0.3.0
  • Component changed from core to architecture: x86 
Finished adding support for jmp 0x8000:0x0 and similar (2003/05/26), including
the more complex:
jmp label
label equ 0x8000:0x0

In addition, "CALL FAR procedure" (and JMP FAR) is supported, although untested
at present due to the lack of object format support which can utilize it.
