a38e9ff12e * if an include file name ends in dot, and the file is not found, also search 
for the file name without the dot. So, for example, if the code contains
  {$I MPAL256.} and 'MPAL256.' is not found, search also for 'MPAL256'

f036e67d8f * fixed the reading of OMF groups by the internal linker. Previously, it only 
worked, when the files had only one group, called 'DGROUP'.

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

 2018-06-22 15:02:39 +00:00
nickysn
f07658d3dc * get rid of TOmfRelocation.GetGroupIndex; instead, read the index property of 
the group object. This adds support for groups, other than DGROUP, when
  writing omf relocations.

git-svn-id: trunk@39276 -

c8fc7c84c8 * avoid adding a section to a group twice in TOmfObjData.createsection 
* add all sections, belonging to a group directly inside TOmfObjOutput.AddGroup,
  based on the TObjSectionsGroup.members array

8a34bd22b8 * pass a TObjSectionGroup object as parameter to TOmfObjOutput.AddGroup, instead 
of the group name

nickysn
d3db9e101a * don't check for the presence of the group in TOmfObjOutput.AddSegmentToGroup, 
because, it is no longer possible for it to not be present (all the groups
  are added beforehand now)

git-svn-id: trunk@39272 -
 2018-06-21 20:33:24 +00:00
nickysn
9a0eca52cb * changed the type of TOmfObjSection.PrimaryGroup from string to 
TObjSectionGroup, so instead of holding the group's name, it now points to the
  TObjSectionGroup object, from which you can retrieve its name or any of the
  other fields and properties it contains

git-svn-id: trunk@39271 -
 2018-06-21 16:28:06 +00:00
nickysn
42f06acaeb + also create the primary section group and add the newly created section to it 
in TOmfObjData.createsection

git-svn-id: trunk@39270 -
 2018-06-21 16:14:42 +00:00
nickysn
f4e26f382f + added an 'index' field to TObjSectionGroup, specifying the index of the group 
in the object file (similar to TObjSection.index, but for groups, instead of
  sections). Set the new index field, when writing .obj files with the internal
  omf object writer.

 2018-06-21 15:51:58 +00:00
nickysn
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.

git-svn-id: trunk@39265 -
 2018-06-20 21:11:19 +00:00
svenbarth
af6f094420 + add reverse_longword() function that reverses the bit pattern for a longword, just like reverse_byte() and reverse_word() do for Byte and Word respectively

git-svn-id: trunk@39260 -
 2018-06-20 19:53:50 +00:00
svenbarth
97acf24290 + add a new modeswitch ArrayOperators which is set by default in Delphi modes that enables the internal array operators (currently only "+") 
git-svn-id: trunk@39259 -
 2018-06-20 19:53:43 +00:00
svenbarth
9b45f58c0b + add flags that allow checking for overloads with isbinaryoverloaded() and isunaryoverloaded() without modifying the passed in node or even checking for normally non-overloadable operators 
git-svn-id: trunk@39258 -
 2018-06-20 19:53:34 +00:00
svenbarth
8536abce8a * as the management operator feature is not platform specific using a specific define for it aside from a 
version check is unnecessary, thus remove the FPC_HAS_MANAGEMENT_OPERATOR define and instead check for VER3_0

git-svn-id: trunk@39257 -
 2018-06-20 19:00:24 +00:00
svenbarth
ac0322c323 + add a flags field to the record init RTTI which declares whether 
a) the current record contains a field with non-trivial initialization
    b) and of the parents contains such a field (only relevant for objects and classes)

git-svn-id: trunk@39255 -
 2018-06-20 19:00:17 +00:00
svenbarth
61bde67082 + add method has_non_trivial_init_child() to tdef which provides access to the symtable's 
sto_has_non_trivial_init flag

git-svn-id: trunk@39253 -
 2018-06-20 19:00:11 +00:00
svenbarth
cc153176f3 + add a new symtable option sto_has_non_trivial_init that is true if the symtable contains a symbol with an 
Initialize() operator (like sto_needs_init_final this flag is calculated on demand)
* increase PPU version

git-svn-id: trunk@39252 -
 2018-06-20 19:00:08 +00:00

22a5e5e4ee * the symbol parsed for "specialize" does not need to be a type; it could be a procsym or some other type (e.g. a constant of the same name in a third unit)

84b5265312 + append a TIS trailer after the debug ELF (this helps the watcom debugger find

239fb25179 + assign an MZExeUnifiedLogicalSegment object to the OMF dwarf sections, so that

nickysn
7103e3cb5c + set the oso_debug section flags when reading an OMF section, which belongs to 
the 'DWARF' class

 2018-06-14 15:27:08 +00:00
nickysn
b7bfac11cb + enable using the i8086 internal linker with debug info, if the compiler is 
compiled with -di8086_link_intern_debuginfo

git-svn-id: trunk@39221 -
 2018-06-14 15:24:39 +00:00
nickysn
5b47bad32a * use uppercase object section names in the OMF linker script for matching the 
dwarf debug sections. This is because they are converted to upper case when
  reading (so that we treat omf section names as case-insensitive)

git-svn-id: trunk@39220 -
 2018-06-14 15:19:11 +00:00
nickysn
c56ebad183 + implemented writing of dwarf debug info (by calling writeDebugElf) in 
TMZExeOutput.writeData. Note that writing i8086 debug info with the internal
  linker is still disabled (i.e. it switches to external linking) in 
  options.TOption.checkoptionscompatibility

29b3ec3fdb * call MaybeSwapHeader and MaybeSwapSecHeader in TMZExeOutput.writeDebugElf, so 
the debug ELF file is generated with the correct endianness

 2018-06-14 13:02:54 +00:00
nickysn
b34ab6b279 * The MaybeSwapXXXHeader functions moved from ogelf to the elfbase unit, so they 
can be used by TMZExeOutput.writeDebugElf as well

b3e4ace4e3 * fixed compilation of .com files in the i8086 tiny memory model, when used with

b9ab9e5782 + initial (experimental) implementation of section-based smartlinking for i8086. 
Use -dI8086_SMARTLINK_SECTIONS to enable.

bfdd75eabf + support AB_LOCAL symbols in OMF object files, by implementing support for 
LPUBDEF/LPUBDEF32 OMF records

git-svn-id: trunk@39210 -
 2018-06-11 15:29:23 +00:00
nickysn
188e9ff64a * only read the first OMF record in TOmfLibObjectWriter.closefile, since we no 
longer copy the entire file there, so we parse the file only to get the module
  name, and the THEADR record should always be the first record in the OMF file.

3f5577077a * automatically create omf libraries with the smallest page size possible. This 
greatly reduces the size of i8086 snapshots by keeping the amount of padding
  in the library files to the minimum.

 2018-06-07 22:27:47 +00:00
nickysn
345713c1fa * refactored omf library writing, so that the whole library is written in 
TOmfLibObjectWrite.WriteLib, after determining the page size (currently still
  fixed to 512 bytes). Prerequisite for OMF lib page size optimization.

git-svn-id: trunk@39194 -
 2018-06-07 22:11:03 +00:00
nickysn
00c6826896 * moved the PageNum property of TOmfLibObjectWriter.TOmfLibDictionaryEntry to 
TOmfLibObjectWriter.TOmfLibObjectModule. Instead, store the module index (in
  FObjectModules) in TOmfLibDictionaryEntry. This is a prerequisite for
  implementing OMF library page size optimization.

git-svn-id: trunk@39193 -
 2018-06-07 18:32:50 +00:00
nickysn
4bcfe8dbb2 * refactored TOmfLibObjectWriter, so it keeps all object modules in a 
TFPObjectList. This will allow implementing omf library page size optimization
  later.

af5e6e182d * the TOmfLibDictionaryEntry class in unit owomflib converted to two identical 
nested classes inside TOmfLibObjectWriter and TOmfLibObjectReader. The reason
  is I'm planning to change the class, used in TOmfLibObjectWriter, but not the
  one in TOmfLibObjectReader. And using nested classes keeps things clean and
  avoids exposing implementation details in the interface of the owomflib unit.
* also changed 'private' to 'strict private' in the classes of the owomflib to
  reduce the risk of interference between TOmfLibObjectWriter and TOmfLibObjectReader.

42efddc481 ncginl: in inc/dec, do not use left.resultdef as the dest to force a register location, because if left is a pointer, then an ordinal value might get forced into an address register on m68k, which results in a lot of unnecessary register shuffling to complete the operation

 2018-06-04 14:00:36 +00:00
nickysn
002b116322 * use a case statement, instead of 'if', based on the OMF record type in 
TOmfObjInput.ReadLEDataAndFixups. This is to allow (in the future) handling of

  functional changes in this commit.

6bd99b65bf + emit DW_AT_frame_base dwarf attributes on i8086. Even though the Watcom 
Debugger doesn't require them (it uses BP as the frame register by default),
  the dwarf spec requires that we emit them on i8086, because we also use
  DW_OP_fbreg on i8086.

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.

git-svn-id: trunk@39098 -
 2018-05-23 15:29:33 +00:00
nickysn
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

  but will probably change to LongWord on i8086, in order to support 32-bit

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.

d1fc31de94 + add support for '[' and ']' parenthesis in addition to '(' and ')' in 
rautils.TExprParse. They behave exactly like '(' and ')'. However, you cannot

bd3d35f2da + add support for passing 32-bit values in a pair of registers in

nickysn
a73aabcc39 * support loading longint in dx:ax when using the 'register' calling convention 
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).

91707deba7 * changed the registers, used by the 'register' calling convention on i8086 to

e1d0e7572e * i8086 TP7 compatibility fixes, related to obtaining procedure addresses: 
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
