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.

pass them to the linker so it does not reorder them
o fixes resource strings on Darwin when using LTO (this used to reorder the
resource string symbols, so they no longer all appeared between the START
and END symbols for their compilation module)
git-svn-id: trunk@41907 -
o renamed jumpalignmax and coalescealignmax to jumpalignskipmax/
coalescealignskipmax to better reflex the meaning of these setting
(and the difference in meaning to e.g. constalignmax)
git-svn-id: trunk@40682 -
o use this flag to set the personality routine of a function if it uses
exception handlinga
o also define FPC_USE_PSABIEH if this target flag is set
o set this target flag for darwin/x86-64 if the compiler is compiled with
-dllvm
git-svn-id: branches/debug_eh@40415 -
+ support of new alignment control values for GNU AS writer
+ support of new alignment control values for binary writer
* better alignment settings on i386-win32
* improved inserted align directives for if nodes
git-svn-id: trunk@40159 -
for all non-ppc(32/64) Darwin platforms
o pass the macosx-version-min/iphoneos-version-min to clang as an assembler,
so that it properly sets this information starting with Xcode 7 (solves
errors when targeting the iOS simulator, and warnings about object files
being compiled for a different OS X version when targeting (Mac) OS X)
o the old assembler is still selectable via -Aas-darwin (required with
Xcode 3.1.x and older)
o since the first Xcode version that shipped with Clang is Xcode 3.2, which
is available for Mac OS X 10.6, most users should not encounter any issues
with the new default (in fact, it fixes some tests for x86 because Clang
supports some instructions that "as" doesn't). Clang does not support
Stabs however, so -gs does require the use of -Aas-darwin
git-svn-id: trunk@31830 -
GNU as from binutils for Darwin, and Apple's "as" is based on an old
version of GNU as)
o this will not cause any backward compatibility problems, as the
previous identifier for as_darwin was "AS-Darwin" and the compiler
compared the uppercase value of the -A parameter to the identifier,
so it was not explicitly selectable earlier. The new name is "AS",
so it is explicitly selectable via -Aas like on other platforms.
git-svn-id: trunk@31806 -
oldcctools are no longer shipped with Xcode 7 and Clang assembler doesn't
support Stabs (and DWARF2 has been working better than Stabs since a long
time already)
git-svn-id: trunk@31774 -
in certain places, the code in the compiler assumes that only one of the two
is defined, resulting in libraries with missing externals when both are
defined and there's no much point in supporting both anyway, since section
based smartlinking achieves the same thing (in a better way) on these
platforms.
git-svn-id: trunk@30668 -
as the AIX abi (especially on ppc64)
o replaced (for now) all checks for the AIX abi with a check for either the
AIX or Darwin abi
o changed the ABI of Darwin/ppc, Darwin/ppc64 and Mac OS/ppc to
abi_powerpc_darwin
git-svn-id: trunk@30202 -
o does not use GOT
o enabled by default like for other Darwin platforms
- removed Darwin/ARM call stub support: no longer needed with current
Xcode versions (at least Xcode 4.2+), and we didn't support PIC
in them yet
git-svn-id: trunk@25325 -
* 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.
