ff2fff365f + added x86 compiler intrinsics fpc_x86_sti and fpc_x86_cli, which generate the 
'sti' and 'cli' instructions

6cd88a24dc * release al/ax/eax immediately after the 'in', before (instead of after) moving 
it to the destination imaginary register. This generates better code.

that are evaluated as a compile-time constant in the range 0..255

fdc896ad0a + inline support for the x86 'in' and 'out' instructions. Currently only enabled 
in the i8086-msdos 'ports' unit, but will be enabled on other targets (e.g.
  go32v2) in the future as well. 32-bit 'in' and 'out' not inlined on i8086, but
  will be on i386 and x86_64.

45337b67fe + when using the i8086 with section based smartlinking, create OMF section 
groups, named 'CGROUP' or 'CGROUP_UNITNAME', which include all the code
  sections, that need to be put in the same segment

ab47c8b899 + introduce the omf_section_primary_group function. Use it instead of 
section_belongs_to_dgroup, to allow sections to belong to groups, other than
  dgroup.

assembler; these are TP7 and Delphi compatible

e5de7d0eac * set all 16/32-bit specific stabs/dwarf register numbers of x86_64-only 
registers to -1 in x86reg.dat. The values that used to be there weren't used
  at all (most were just copies of the 32-bit version of the register). This can
  be easily demonstrated by the fact that running 'make regdat' in the compiler
  directory doesn't change any of the generated files for i8086/i386/x86_64.

a275d15da2 + added an i8086-specific column in x86reg.dat for the dwarf register numbers 
and filled it with the dwarf register mapping, used by Open Watcom (Watcom
  also uses this mapping on i386, but we don't need to support their debugger on
  i386 for now)

c530e031b1 * synchronize get_saved_registers_int and get_volatile_registers_int for all 
calling conventions on i386
* generated code at the caller side for pocall_pascal routines on i386 no longer
  assumes the routine destroys all registers (except ebp) - instead now it
  assumes that it preserves the ebx,esi,edi and ebp registers. This is
  compatible with the pascal calling convention of 32-bit delphi and was already
  honoured by FPC on the callee side.
* updated the list of calling conventions that save all registers, used in
  tx86callnode.can_call_ref, so it is accurate on all x86 platforms - i8086,
  i386 and x86_64.

a8a627f334 - removed the _count_asmdirectives and _count_asmoperators constants from the

  tasmtoken directly as index.

4686f61002 * keep track of the temp position separately from the offset in references, 
so that they can still be freed after the reference has been changed
    (e.g. in case of array indexing or record field accesses) (mantis #33628)

518cdf9674 * replaced the saved_XXX_registers arrays with virtual methods inside 
tcpuparamanager, very similar to the existing get_volatile_registers_XXX. The
  new methods are called get_saved_registers_XXX, where XXX is the register
  type ("int", "address", "fpu" or "mm")

fa3ee68004 o patch by Dávid Pethes: Fixes for compilation with nasm 2.10 and higher on Win64:
