2af5c9d508 * changed type used for section alignment from byte/shortint to longint, so the 
internal object writer and the internal linker support object files with
  sections with alignment >=256

76445fd4b7 + add ability to generate Big Obj COFF files if required due to the section count being higher than $7fff 
Note: such files can be linked GNU ld only starting from 2.25; then again the older versions would fail anyway as they'd complain about a too high section count...

95bea696ca + add ability to read Big Obj COFF files as generated by MSVC with /bigobj and GNU AS with -mbig-obj (starting from version 2.25); this format allows 2^31 sections per COFF file instead of 2^16, thus solving the problem of compiling packages\odata\src\sharepoint.pp 
Note: the field names of tcoffbigobjheader and coffbigobjsymbol are inspired from the field names of the structs declared in LLVM

991e1f49bd * store a pointer to the used tasminfo record in every assembler writer, so

    in LLVM IR)

9e5979e8be Implemented UAL syntax support in the ARM assembler reader. Can be toggled with a field for now, but not implemented yet. Still using pre-UAL syntax for now. 
Switched codegeneration of VFPv2 and VFPv3 to use UAL mnemonics and syntax.
Updated VFP code in RTL to use UAL syntax too.
Added preliminary ELF support for ARM.
Added support for linking of WinCE COFF files. Should work for with a standard ARMv4-I target.

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).

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.

b86372ccec + Internal linker: process unreferenced .pdata sections on x86_64-win64, restores the possibility to use GAS on win64 (which got broken by introducing SEH).

999c3a0a02 * COFF linker: postpone import section generation until unreferenced sections (and imports) are removed, and put all remaining imports into a single section. This is much more efficient than generating multiple smart-linkable import sections and immediately discarding a good half of them.

36859068f5 * Propagate AS_NEEDED flag further into Load_DynamicObject and handle it properly: shared objects marked with AS_NEEDED are added to dependencies only if they actually resolve some symbol. 
* Dropped TObjInput.newObjData method. Instead, TObjData instances are created directly in ReadObjData, this gives possibility to create a different type of TObjData based on file header.
- Dropped TObjInput destructor, it does nothing except calling inherited.

fde944bf5d + Declare AT_TLS and AT_GNU_IFUNC symbol types, these are needed to handle object files created by gcc in ELF internal linker. 
* TExeOutput.FixupSymbols:
  + Collect AT_GNU_IFUNC symbols in IndirectObjSymbols list for further processing by ELF back-end.
  * Do not overwrite bind and size while fixing AB_COMMON symbols, this removes need in storing symbol size in every relocation and dedicated handling of oso_common section.
  * Remove symbols with objsection<>nil from lists, so calling FixupSymbols several times skips already processed symbols.

c41b407119 * Changed TObjSection.WriteStr method to write a zero byte after the string.

ec56677927 + Added method TObjSection.writeReloc_internal to write relocations to given section+offset without need to have a symbol at target location.

  - Don't create .idata$6 sections for imports by ordinal.

95535ea845 - Do not create any default object sections. On targets with section-based smartlink these sections remain empty and only cause linker to do useless job of removing them. The same happens when loading object files because duplicate section names are allowed at that time. On targets without smartlink they don't stay empty, but the internal assembler creates sections when required, so not creating initial sections effectively doesn't change anything.

1d09005542 + Implemented two-stage removal of empty exe sections. Candidates for removal are first marked with oso_disabled flag, then actually removed. Descendants of TExeOutput that override MemPos_Start may modify list of sections pending removal. In particular, the COFF-specific .reloc section no longer has to be handled in base TExeOutput class.

c65abdeeae * Implemented link map generation without involving TObjSection.ObjSymbolDefines, and removed the latter because it isn't used otherwise. The new approach uses CPU/memory only when map generation is requested.

0c32756ef3 - removed TCoffObjData.afteralloc, calculating MemPos there is useless because every call to afteralloc is immediately followed by call to TObjData.resetsections that resets all MemPos back to zero. 
- PE_FILE_RELOCS_STRIPPED flag is meaningless for object files.
- Don't write PE_FILE_BYTES_REVERSED_LO as well, it is deprecated and GNU tools don't write it either.
- Don't set PE_FILE_32_BIT_MACHINE flag in x86_64 object files.

8c8883cc35 * Once TExeOutput is accessible in TObjSection.fixuprelocs, its ImageBase can be used directly, without a need to have a copy in every TObjSection. 
* Also simplified COFF symbol loading, separate array of symbol sizes is not needed because these sizes never change during the load.
