d6de2c03cb * generic part of r26050 from the hlcgllvm branch: made tcgvecnode hlcg-safe 
o in particular, add tdef size information to the update_reference*()
     methods, and factored out offset adjustments into its own method
   o also make sure the passed size to update_reference*() corresponds to the
     actual size of the index, as it's no longer guaranteed to be ptruint
     since the previous commit

a637fbe596 * moved all g_exception_*() methods to hlcgobj and cleaned them up (no more 
hardcoded registers for the most part)
  + added extra g_exception_discard_reason() that can be called when we only
    want to get rid of the currently pushed exception reason, and don't have
    to load it (so it can do nothing on platforms that don't use push/pop)

nickysn
36d63b953e + added an i8086 specific boolean property is_huge to the tarraydef. For now it 
will only be used for indexing huge pointers (i.e. only huge arrays with the
  ado_IsConvertedPointer array option will be supported). In the distant future,
  regular huge arrays may be supported as well (but that would require
  substantially more work, including adding hugeness support to other structures
  such as records, objects and classes, so I'm not planning on doing it anytime
  soon).

1910177cf0 + added heapmax support to the $M directive on i8086-msdos. It is currently 
only implemented in the near data memory models. The far data models support
  is still a TODO.

nickysn
7cfd7a66cd + create a special 'heap' segment with reserved space equal to heapsize (i.e. 
the value set by -Ch or the second parameter to the $M directive). This is
  equivalent to the heapmin value in Turbo Pascal 7 and ensures that the program
  has at least this amount of heap space available (otherwise DOS will show a
  'not enough memory' error and will refuse to load the program).

dc628b8969 * x86: Completely skip instructions that do not exist for target CPU bit width. The existing behavior of writing mnemonics and properties but no encoding allows an invalid instruction to be recognized by assembler reader or even generated by compiler, but it but won't assemble anyway.

73d7f2aa18 * let the compiler generate the stack segment in i8086 near data memory models 
as well. Even though, in these models, the stack is dynamically allocated
  (because it goes on top of the heap, but the heap is variable size), there are
  still benefits:
  1) the program will run on a larger stack during initialization, before the
     actual stack (and heap) are ready
  2) in cases, when the system is extremely low on memory, DOS will reject to
     load the program if there's not enough memory for the stack the program
     requires. This way the startup code can be further simplified by omitting
     the 'not enough memory' check in the future (when we add the minimum heap
     size to the executable reserved space as well).

3cc8ff11e3 + generate the stack segment for i8086 far data memory models from within fpc 
itself (instead of having a fixed 16k stack in the startup code). This allows
  setting the stack size in these models with the -Cs option.

feb840b47f * support reg=NR_NO in thlcgcpu.reference_reset_base on i8086. This fixes test

906d828ee0 * tcg8086.g_copyvaluepara_openarray: fix for the case where ref.segment is 
specified, but equal to DS in the current memory model -> call the high level
  code generator with a near pointer type in order to force the segment to be
  ignored

git-svn-id: trunk@27716 -

c9c29a3cd4 + ignore the source segment, when the destination cgpara is a near pointer in 
tcg8086.a_loadaddr_ref_cgpara

git-svn-id: trunk@27715 -
 2014-05-01 21:56:04 +00:00
nickysn
c9f8703679 + set ref.segment to NR_SS for all temps/localvars on i8086. This allows the 
segment to survive e.g. several nested vecnodes, which cause the base register
  to change from BP to something else. In the cases where the ss: prefix is not
  needed, it is removed by make_simple_ref.
+ remove the ss: prefix in the several cases where make_simple_ref isn't called
  (namely spilling and tcg8086.a_call_reg_far)

 2014-05-01 21:18:47 +00:00
nickysn
38aec68d6f * ti8086vecnode.update_reference_reg_mul: remove the segment before calling 
base, because base may in some cases call cg.a_loadaddr_ref_reg, which will
  overwrite the next register, if the source reference contains a segment

git-svn-id: trunk@27713 -
 2014-05-01 19:39:52 +00:00
nickysn
3dfc6ac7e1 * fixed the passing of extended floating type parameters on i8086 for 
pocall_register after r24761 (it is the same change as in r24766, but for
  pocall_register)

906412411f * fixed the passing of pushaddr paramaters for pocall_register in i8086 far data

7da8719036 + support near pointers, bound to a segment register in hlcg.reference_reset_base

nickysn
e8b9d9bf41 * converted tcgtypeconvnode.second_nil_to_methodprocvar to the high level code 
generator, so it handles i8086 near and far pointers generically
- removed t8086typeconvnode.second_nil_to_methodprocvar, since it's no longer
  necessary

nickysn
187c2af20e * tcgtypeconvnode.second_proc_to_procvar converted to the high level code 
generator, so it can now handle i8086 near and far pointers generically
- removed almost all of t8086typeconvnode.second_proc_procvar, since it's no
  longer needed. Only a few assertions are left there to ensure that we don't
  accidentally attempt to take the address of a near procedure in a far code
  memory model, because the calling conventions are incompatible.

git-svn-id: trunk@27677 -
 2014-04-27 23:18:05 +00:00
nickysn
313240b9e8 * use a better way (suggested by Jonas) to determine whether a procedure is from 
the same unit

git-svn-id: trunk@27629 -
 2014-04-21 23:14:16 +00:00
nickysn
8a606761cd * don't push cs in ti8086callnode.extra_interrupt_code in the far code memory 
models, because in these models, interrupt procedures are treated as far and
  an appropriate far call (or push cs+near call if in the same segment) is made
  anyway

git-svn-id: trunk@27622 -
 2014-04-21 00:56:51 +00:00
nickysn
70a7ecd0fa + use 'push cs + call near' (which is both shorter and faster), instead of far 
call, when calling a far proc in the same segment

git-svn-id: trunk@27621 -
 2014-04-21 00:44:45 +00:00
nickysn
597f110eb9 + added support for units with code larger than 64kb in the far code i8086 
memory models. Enabled by the new directive {$hugecode on}. The directive is
  ignored in the near code memory models. When enabled, it forces each procedure
  to be in a separate segment and disables mixing near and far procedures (so
  'near' and {$F-} are ignored in this mode). Note that {$hugecode on} does not
  count as a different memory model, because you can freely link modules (units)
  compiled with {$hugecode on} and {$hugecode off}.

git-svn-id: trunk@27615 -
 2014-04-20 19:03:14 +00:00
nickysn
bf6ad0ff78 * fixed tcg8086.g_flags2reg, so it behaves the same way as tcgx86.g_flags2reg 
after r27581 in regard to floating point comparisons. The tcmpnan.pp test now
  almost works (i.e. fails due to only one error, instead of many).

 2014-04-19 22:54:29 +00:00
nickysn
9a44ab2fc2 * always treat interrupt routines as far, so their address can be taken even in 
{$F-} mode

git-svn-id: trunk@27591 -
 2014-04-16 23:37:28 +00:00
nickysn
d6ad2b1f8a + added support for mixing near and far procedures in the i8086 far code memory 
models. The $F directive and the 'near' and 'far' procedure modifiers should
  now work as expected in the far code memory models (they are still ignored in
  the near code memory models). The compiler defaults to the {$F+} state,
  because {$F-} requires adding 'far' to a lot of procedures in the rtl,
  packages and tests.

98de3c4e40 * tcg8086.g_flags2reg: call virtual method a_jmp_flags instead of duplicating its functionality, it prevents further changes to this method when adding support for unordered comparison results.

nickysn
d8d3706462 + override hlcg.a_call_name for i8086 and dispatch to the appropriate type of 
call (near or far), according to whether the procdef is near or far, instead
  of relying on the default for the memory model

git-svn-id: trunk@27562 -
 2014-04-13 15:17:43 +00:00
nickysn
6fe362a1b0 + added method is_far to i8086's tcpuprocdef and tcpuprocvardef 
+ added helper function to i8086's symcpu is_proc_far that dispatches the call
  to the proper is_far method (because we can't make a cpu specific descendant
  of tabstractprocdef and add it there)
* all checks for (po_far in procoptions) in the i8086 code generator replaced
  with calls to is_proc_far

git-svn-id: trunk@27559 -
 2014-04-13 12:41:46 +00:00

40a6a9c820 + added i8086 specific implementation of thlcgcpu.a_load_loc_ref, which handles 
6-byte method pointers and other i8086 types that use loc.registerhi
* changed the i8086 specific code in tcgassignmentnode.pass_generate_code to
  use hlcg.a_load_loc_ref

nickysn
2e7aab0155 * refactored i8086's thlcgcpu.location_force_mem: 
o The checks for types that need special handling moved to separate methods,
    because they'll probably be used by the other hlcg.a_load*loc* methods as
    well.
  o Use voidcodepointertype and voidpointertype to avoid the ifs for checking
    the memory model.

   o added cpusym unit for every architecture that derives a tcpu*def/tcpu*sym
     class from the base classes, and initialises the c*def/c*sym classes with
     them. This is done so that the llvm target will be able to derive from
     the tcpu*def/sym classes without umpteen ifdefs, and it also means that
     the WPO can devirtualise everything because the c* variables are only
     initialised with one class type

o When expanding from a OS_8 to a 16-bit or 32-bit tcgsize, use the R_SUBH
    subregister to initialize the high 16 bits of the register to zero. This
    generates shorter and faster code, without increasing register
    interferences, because R_SUBH has the same register constraints on i8086 as
    R_SUBL, which is already used on the same imaginary register.
  o After performing operations on the 8-bit subparts of a register that was
    initially 16-bit, call makeregsize(OS_16) to notify the register allocator
    that the register is once again 16-bit.

   o Correctly support the case when converting from 16-bit to 32-bit int.

using it in inline asm causes an internal error and removing it didn't show
  any regressions after running the testsuite on i386-linux.

all other platform's cpubase.{inc,pas} (except alpha, ia64 and vis which are not up to date):

5af873ee5b * x86 targets: Profiling shows that quite a bit of time is spent in findreg_by_number(), despite it uses binary search. Worse, it is repeated for every piece of register information. Trying to get rid of some of these calls: rearranged registers so that their "opcode" matches 3 LSBs of superregister number (with a few exceptions described at the beginning of x86reg.dat). This allows to lookup opcodes in regval() with O(1) complexity, and removes need in rXXXop.inc files.
