ada6d8ce5e * the .pdata section currently only needs to be always included for arm-wince (at least until we have full SEH support there as well)

2b59000d56 + implement compiler support for SEH on Win64 
Note: due to the way we access variables in a nested function (which in this case includes exception filters) we can not extract the finally handlers and call them (like we do on i386 and x86_64, but instead we duplicate the finally code)

61358b1eaa * it's rather useless that sectiontype2options is virtual as we can't use a class type, not to mention that the classes doing the overriding are for the internal assemblers/linkers, but we need it also for external 
Thus we move the functionality of the overloads to the basemethod and remove the virtual directive; maybe we'll find a better solution in the future...

3fee990218 * on Mach-O, PECOFF and ELF platforms, write local symbols as hidden/ 
private_extern (or plain global in case of PECOFF, as the effect is
    the same there): visible across object files, but they become local
    when linked into a binary/library. This enables cross-unit inlining
    of functions accessig implementation-only symbols.

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 
that we can use assembler writers with different conventions from the

    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.

8c61990078 * ogcoff.pas: when encountering symbol of unsupported type in input object file, give a meaningful error message instead of internal error. Mantis #27020.

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

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.
