so that they can still be freed after the reference has been changed
(e.g. in case of array indexing or record field accesses) (mantis #33628)

o separate information for reading and writing, because e.g. in a
try-block, only the writes to local variables and parameters are
volatile (they have to be committed immediately in case the next
instruction causes an exception)
o for now, only references to absolute memory addresses are marked
as volatile
o the volatily information is (should be) properly maintained throughout
all code generators for all archictures with this patch
o no optimizers or other compiler infrastructure uses the volatility
information yet
o this functionality is not (yet) exposed at the language level, it
is only for internal code generator use right now

it was AT_NONE, which is invalid and should never be used
* explicitly pass the correct value for all calls to those methods elsewhere
in the compiler

tasmdata.DefineAsmSymbol() and all routines that call it
o will be used to automatically generate AB_INDIRECT sybols when
necessary

Provide a possibility to ignore duplicate symbols for exporting.
export.pas, texportlib:
+ new property "ignoreduplicates" with which duplicate symbols are ignored upon insertion
+ new method "duplicatesymbol" which checks "ignoreduplicates" and generates an error if it is False (this method needs to be used if a duplicate was detected)
expunix.pas, texportlibunix:
* exportprocedure: use "duplicatesymbol" instead of always generating an error
systems/t_beos.pas, texportlibbeos:
* exportprocedure: use "duplicatesymbol" instead of always generating an error
systems/t_haiku.pas, texportlibhaiku:
* exportprocedure: use "duplicatesymbol" instead of always generating an error
systems/t_nwl.pas, texportlibnetwlibc:
* exportprocedure: use "duplicatesymbol" instead of always generating an error
systems/t_nwm.pas, texportlibnetware:
* exportprocedure: use "duplicatesymbol" instead of always generating an error
systems/t_win.pas, texportlibwin:
* exportfromlist: use "duplicatesymbol" instead of always generating an error

different 'ar' implementations under different platforms
* use the omflib reader instead of the ar reader in the msdos internal linker
git-svn-id: trunk@31322 -
* Changed direct references to linker classes in TSystemInfo records to enumerated ids.
* RegisterExtennalLinker and RegisterInternalLinker procedures replaced by single RegisterLinker procedure and moved to link.pas.
- TAbstractLinker is no longer necessary, removed.
This change allows to register linker once per id, rather than once per target, and also allows TSystemInfo records to be read-only.

rather than with single/double quotes depending on the target platform
(ld only supports double quotes), and rather than only quoting when
necessary (wastes time since quotes are always allowed, and double
quotes inside a directory name cannot be escaped for ld; they are
simply not supported by the program) (mantis #22059, follow-up to
r21069 and r21208)
git-svn-id: trunk@21343 -
that deal with paths/filenames with TPathStr (= ansistring) to prevent
cutting off long paths (no change in speed when compiling the compiler,
1% extra memory usage)

local procedure AddImport: Use same RIP relative code
as in ogcoff unit for x86_64 CPU to allow a VMA above
0x100000000 even when using.
TImportLibWin.generateidatasection;
also used RIP base for import libraries created using -WI option.
git-svn-id: trunk@19161 -
* Changed alignment of .pdata section to 4.
+ Support saving RELOC_NONE relocations to .o files and reading them back on x86_64.
git-svn-id: trunk@19070 -
in Windows, Emx and OS2 targets.
This fixes test failures: test/library/tlib1b.pp and lib2b.pp
link unit TLinker.AddImportSymbol: Added symmangledname parameter.
ogbase unit TImportSymbol.Create: Add AMangledName parameter.
fmodule unit TModule.AddExternalImport: Add symmangledname parameter.
fppu unit: Also put mangled name string for imported symbol.
ppu unit: Increase PPUVersion
utils/ppudump.pp: Adapt to PPU change above.
systems/T_OS units: Use ImportSymbol.MangledName property to create
import libraries or .idata sections.
git-svn-id: trunk@17804 -
* assemble.pas (TInternalAssembler.WriteStab): Use RELOC_ABSOLUTE32 for
32-bit stab entry.
* ogcoff.pas: Add check for correct generated reloc section size.
* systems/t_win.pas: Use 0x400000 image base for x86_64 programs using
stabs debug information format.
git-svn-id: trunk@16056 -
* changed type of minstacksize, maxstacksize and imagebase from aword
(= size of integer registers of the target platform) into puint
(= size of address space of target platform)
