2c05bcc28f + i8086-msdos internal linker: in the far data memory models, fill 
MaxExtraParagraphs in the MZ exe header according to the specified max heap
  size

f3d5bf3743 * the result of tobjsymbol.address changed from 'aword' to 'qword' as well 
git-svn-id: trunk@31414 -
 2015-08-25 00:19:26 +00:00
nickysn
8977c0fc78 * TExeSection.Size and .DataPos changed from aword to qword, because: 
1) aword follows the ALU size of the CPU, not the address type
  2) MemPos is qword and is already checked against MaxMemPos

677595880a + support for get_frame() for the LLVM target (using the llvm.frameaddress() 
intrinsic)

be9d2b1c26 * implement concatcopy for complex types by calling the llvm.memcpy() 
intrinsic. This may insert actual calls to a function called memcpy with
    the signature of the libc function, but llvm optimizers are free to
    insert such calls by themselves already. This means that for non-libc
    targets, we will have to add weak symbols for memcpy/memmove/memset
    that call through to move/fillchar when using LLVM, so that these
    implementation are used when not linking to libc

052af9200e * support external declarations for compilerprocs 
o since there is no separate implementation for them, we have to immediately
     convert the symbol to lower case after parsing the declaration

0eb1cd157a * don't subtract two from the end of the stack segment when calculating the 
initial SP value - seems to be wlink compatible

2431b6e63b * i8086-msdos internal linker: use a different approach for finding the stack 
segment - either its class name must be 'STACK' (wlink compatible) or its
  combine type must be scStack (tlink compatible)

d7f08866e5 * use the TMZExeOutput.MZFlatContentSection property in TInternalLinkerMsDos.GetTotalSizeForSegmentClass 
instead of finding the exe section by name

173713ce57 * preserve original order (as specified in the link script) of omf sections with 
the same name. This ensures that the startup code always comes first, which is
  important for .com files

git-svn-id: trunk@31377 -
 2015-08-24 00:30:24 +00:00

fa9a1f706b + i8086-msdos internal linker: calculate the final segments and groups locations 
in memory (incl. segment bases) before DoRelocations; list segments and groups
  in the map file as well

5dc42404cf * capitalize omf segment class names, as that's how other 16-bit compilers write them 
git-svn-id: trunk@31371 -
 2015-08-22 19:07:04 +00:00
nickysn
e09ab50724 * capitalize the group name 'DGROUP' in the generated omf object files, because 
that's how it is usually written by other 16-bit compilers

git-svn-id: trunk@31369 -
 2015-08-22 16:28:36 +00:00

nickysn
9aeb94676c + added virtual method to tobjsection for returning a string representation of 
the section's base address for the internal linker map file
* implemented it for omf sections to return the address in 'seg:ofs' format

git-svn-id: trunk@31359 -
 2015-08-21 16:21:16 +00:00
nickysn
a762532ae1 * changed the MemPos field in TObjSection and TExeSection from aword to qword: 
1) aword follows the ALU size of the CPU, not the address size
  2) it is already qword in TExeOutput and its methods and there's already
     MaxMemPos to check if the limits of the platform/exe format have been
     exceeded

 2015-08-20 23:24:54 +00:00
nickysn
808b5dfb78 * allow gaps between LEDATA records, as nasm seems to produce them. They're 
automatically filled with zeros. This fixes reading of the tiny memory model
  startup code object module by the i8086-msdos internal linker.

git-svn-id: trunk@31354 -
 2015-08-20 22:57:15 +00:00

git-svn-id: trunk@31340 -
 2015-08-18 14:41:29 +00:00
nickysn
d4b0b6f6e6 * use SegmentName+'||'+ClassName for the name of OMF sections when reading OMF 
files, because omf segments are (according to the spec) identified by the
  tuple <SegmentName,ClassName,OverlayName> and not just by name (and we ignore
  the overlay name)

Jonas Maebe
add015f808 * ensure that the dwarf file table contains an entry if the current unit 
contains any code, even if we cannot generate any debug info for that

e06181749c * guarantee the order of parameter pushes again after r31201 on platforms 
that don't use a fixed stack (mantis #28454)
   o moved the code to finalise managed out parameters from ncgcal to ncal,
     and add it to the init code of the call node (so it's evaluated before
     any parameters are processed, ensuring that mantis #28390 stays fixed)

git-svn-id: trunk@31328 -
 2015-08-16 12:47:09 +00:00
Jonas Maebe
c95a3f2cf7 * firstpass rather than typecheckpass statements added to the call node 
init/done block, as these can be added while pass_1 is ongoing

41203a9152 * support far classrefdef targets on i8086 in thlcgcpu.a_loadaddr_ref_reg. This

bfa94ae908 * further (final?) reworking of llvm external symbol handling: 
o all external symbol definitions are now inserted in the llvmtype post pass
     based on all declarations and types used in llvm instructions
   o this means we don't have to use the workaround with the Pascal mangled
     names anymore for all external names, as we now insert the external
     references only once we know all type information

a58504990a * fixed llvm handling of routines that are normally declared in the

    external routine

d7f6744f7b * converted ncgrtti to the high level typed constant builder 
o the result is still not very clean due to the fact that this data
     is almost completely unstructured due to variable-length strings
     everywhere, which means that
    a) we cannot just load recorddefs from the system or typeinfo unit
       and use those as templates
    b) we cannot easily reuse the recorddefs we create ourselves (except
       if the strings have the same length -- this is the reason for all
       of the names specified to begin_anonymous_record: to reuse defs
       as much as possible rather than creating new ones all the time)

       explicit alignment on platforms that need it

945fd4fcf5 * wait till the end of typecheckpass before we load a call context's self 
parameter instead of immediately doing it in the constructor of the call
  node, and then only create it if we actually need it.

  It was previously created in the call node constructor because it needs to be
  done before pass_1 (which is where it is actually used) due to pass_1 possibly
  being performed in the context of inlining (and then a wrong self parameter
  may be found, or none at all), and it was done unconditionally because at that
  point we don't know yet whether or not a self parameter will be necessary (as
  we haven't resolved the overloads/procdef yet).

  The problem with this is that if we use the parentfpstruct way of handling
  accesses to outer scope locals/parameters, we need to know all locals/
  parameters that will be accessed from nested routines after typecheckpass,
  otherwise we get crashes. The problem was that if a call to an RTL routine was
  generated by the compiler in a routine nested inside a method during pass_1,
  and this nested routine itself did not access self of the method (so self was
  not added to its parentfpstruct during the typecheckpass), then the
  unconditional reference to self when creating the call caused a compiler
  crash (introduced in r30908)

cf2e46c2c1 * reworked external symbol handling on llvm to deal with the fact that 
a single external symbol may be used with multiple declarations that
    have different types:
   o always declare an alias with the Pascal-mangled name that aliases the
     external symbol, with the type of that Pascal declaration
   o if the external symbol is not actually external but in the same unit,
     we will determine the type of that symbol via its declaration and
     insert type conversions in the alias declarations in case they use a
     different type
   o if it is external (so there is no declaration from which we can determine
     its real type) and there are nevertheless multiple aliases for it with
     different types, we just take the type of the first alias and insert
     type conversions for the other aliases. LLVM will take care of the
     conflicting types in multiple modules when performing WPO if necessary

03880c2f74 Added some peephole optimizations, and fixed generic unconditional jump optimizations, for AVR. 
Fixed multiplication code generation for AVR controllers without mul instructions.
Added handling of the old interrupt procedure directive such that procedures with that use RETI instead of RET.

822b943d08 - removed most special handling of self (the self parameter has had the 
correct type since quite a while)
   o exceptions:
    o objects/records (self is a "var" parameter there, and sometimes
      we want to load it as a pointer to an object instead
    o Objective-C class methods, where self has to be id (to have a signature
      compatible with what Objective-C compilers generate), but when loading
      it we want a classrefdef of the current class for type check and
      method resolving

* create separate nodes for Objective-C in tloadvmtaddrnode.pass_1
    instead of implicitly relying on the fact that the Objective-C
    ISA field is at the same offset as the VMT of Object-Pascal
    classes
   o translate the resulting loads of ISA field into direct pointer
     accesses, so that even on non-fragile ABI platforms we don't
     go via an indirection (like clang/gcc)
