3f2057a2f2 * do not generate blx instructions, the generation of blx instead of bl was introduced some years ago but today it proves to be wrong: if necessary, the linker converts the bl into a blx, this is also how gcc and clang handle it

71cdedea82 Add missing NOP, and B instruction forms. 
Move ThumbFunc flag from section to symbol.
Make .w forms optional the other way around. If .w is explicitly put on an instruction the assembler should always chose a wide form.

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.

94a045aa3d * Moved declarations of TFPURoundingMode,TFPUExceptionMask and TFPUPrecisionMode to System unit. Declarations in Math unit changed to aliases. 
* Changed type of softfloat_exception_mask and softfloat_exception_flags to TFPUExceptionMask, softfloat_rounding_mode to TFPURoundingMode.
- Cleaned out numerous conversions happening when getting/setting exception mask and rounding mode.

3d0dd28350 Improve memory barriers on ARM 
- memory barriers are only needed on armv6 and up
 - DMB on ARMv6 is "mcr 15, 0, r0, cr7, cr10, {5}", not "mcr 15, 0, r0, cr7, cr10, {4}"
 - improve write barrier on armv7 by using "dmb st" instead of "dmb sy"
todo: The use of the correct barrier code should be determined during runtime.
