Fixed a bug where ARMv7M targets would not use the DIV instructions.
Moved many size-optimizing Thumb2 peephole optimizations to PostPeepHoleOptsCpu. Previously those optimizations could make it impossible to reuse the shared arm peephole optimizations.
Reenabled a fixed MLA/MLS peephole optimization.
Refactored some FindRegDealloc+regLoadedWithNewValue into RegEndOfLife calls.
Fixed some broken UXTB/UXTH optimizations. Previously they would also match UXT* instructions with ROR shifter ops.

o don't link by default
o when generating profiling info, link gcrt1.o and specify "-no_new_main"
linker parameter
* don't use version-specific crt1.o files when targetting the
iPhoneSimulator platform
* don't link a crt1.o file when targetting iOS 6 or later
(all info from
http://llvm.org/svn/llvm-project/cfe/trunk/lib/Driver/Tools.cpp )

1) less special cases needed in fpmkunit for i8086-msdos
2) consistency with the naming scheme on the go32v2 target
3) we didn't follow the DOS naming scheme completely anyway, e.g. we used .o
for object files, instead of .obj
git-svn-id: trunk@25641 -
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.
git-svn-id: trunk@25279 -
* For common symbols, report objdata of the original ObjSymbol, not of the resolving one, so the map file shows where it comes from.
+ TElfExeOutput.OrderOrphanSections method, handles object sections not mentioned in script similar to ld.
- t_linux.pas: removed sections that are not part of ld scripts, they are now handled by OrderOrphanSections.
git-svn-id: trunk@25184 -
Also adjusted all Windows (Win32/64/CE) units to define a "UNICODE" if "FPC_OS_UNICODE" is defined (except the Jedi units).
Also the common RTL units that checked for UNICODE now check for FPC_OS_UNICODE.
git-svn-id: trunk@24420 -
* Change it also in TInternalLinkerGo32v2.DefaultLinkScript method.
