procoptions even when it's through an array-of-const parameter
* always call create_varargs_paraloc_info() instead of create_paraloc_info()
in the former case, even when no varargs parameters are specified (because
on some platforms even some non-variadic parameters need to be passed
differently, such as on ARM with gnueabihf)

hiding the method name of the wrapped routine
o also add a few more '&' prefixes to the generated wrapper code to
prevent issues when keywords are used as identifiers

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.

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)

information. Only enabled on i8086 (for now). Does not do much yet, but
hopefully, soon it'll start emitting line number information for i8086-msdos
that is usable by DOS debuggers.
git-svn-id: trunk@39006 -
modify the SI and DI registers. For 'register', this makes it compatible with
Borland C++'s __fastcall calling convention, while 'cdecl' becomes compatible
with Borland C, Microsoft C and Watcom C.

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)

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")

tcg8086.a_load_const_cgpara. This fixes passing const longint parameters in
dx:ax when using the register calling convention on i8086.
git-svn-id: trunk@38785 -
on i8086. This is compatible with Borland C++ 3.1's _fastcall. Note that
passing parameters in multiple registers is not yet implemented, so using this
will cause internal errors, but these will be fixed later (and the 'register'
calling convention was never officially supported on i8086).

models. Even though, they generate less efficient code, they are useful when
interacting with external APIs (e.g. declaring callbacks for the Win16 API).
git-svn-id: trunk@38726 -
o The @ and Addr() operators in TP or Delphi mode can now be applied to both
near and far procedures and they always produce a CodePointer, regardless of
the call model of the procedure.
o Ofs() and Seg() can now also be applied to both near and far procedures.
o The @ and Addr() operators in non-TP/Delphi modes, as well as the procedure
name itself in TP/Delphi modes now can be applied to both near and far
procedures and produce a near or a far procvar.
git-svn-id: trunk@38691 -
procvars can be declared near or far. Methodpointers/nested proc vars, etc
must still follow the default calling model of the current memory model. Note
that this feature isn't TP7 compatible (TP7 doesn't allow near procvars at
all), but is common to 16-bit C compilers and is quite useful for calling
external code (e.g. for far calling BIOS or some other real mode API entry
points from any memory model, etc.)
git-svn-id: trunk@38595 -
determine whether to issue a near or a far call in ti8086callnode.do_call_ref.
This will allow adding support for near and far procvars in any memory model.
