68303b8df1 * add explicit check that argument of sizeof(x) is a simple load node (this

04d8e8a5dc * On 64-bit targets, handle abs(int64) internally, using the same code as for abs(longint), i.e. without branching. Both generic and x86-specific pass 2 code is already suitable for different operand sizes, only type checking needs removal of excessive conversions to 32 bits.

34394d6925 Fix for Mantis #26180. Accept undefineddef as first parameter type of an Assert if it is used inside a generic. 
ninl.pas, tinlinenode.pass_typecheck:
  * if the first parameter of an Assert is a undefineddef node then accept it as well if the node is part of a generic function/method

274c2fc82f * handle_ln_const: if/else branches were swapped, correct values are: ln(0)=-Inf and ln(-#)=NaN. 
* handle_ln_const and handle_sqrt_const handle all arguments, not just invalid ones, so calling code can be simplified.

743326dc70 * abs(): when translated to generic fpc_abs_real() helper, typecast result back to original precision, similar to how it is done for sqr and sqrt. Fixes compilation on m68k after r27808 (m86k looks like the only target still needing this generic handling).

22e099d000 * sqrt(real): for targets with emulated floating point, invoke float64_sqrt or float32_sqrt from softfpu code. Testing on ARM CPU shows that float64_sqrt executes about twice faster and offers better accuracy than fpc_sqrt_real from genmath.inc. 
* softfpu.pp: changed float64_sqrt into a function, so it is consistent with other compiler-invoked routines.

fc5f45f65c * sqr(real) and sqrt(real): remove typeconv node inserted by initial call processing (see explanation in comments), allowing these functions to be evaluated using precision of argument. In particular, sqrt(single) and sqrt(double) now emit 'sqrtss' and 'sqrtsd' instructions on x86 targets with -Cfsse3. Non-x86 targets already have the necessary support in code generators. 
* abs(real): handle the same way as sqrt and sqr, i.e. without casting to bestreal and back.

d88d644925 + support for FMA intrinsic: if there is no hardware support, the compiler throws an error. 
Currently it is implemented only for x86-CPUs supporting the FMA extension. While it would
  be possible to implement it in software or simulate fma(<single>,<single>,<single>) using
  double operations, it makes no sense in my opinion to do so.

b57c95043f + support overriding tdef/tsym methods with target-specific functionality: 
o made all (non-abstract) tdef and tsym constructors virtual
   o added c*def/c*sym classref types for every (non-abstract) t*def/t*sym
     class
   o added cpusym unit for every architecture that derives a tcpu*def/tcpu*sym
     class from the base classes, and initialises the c*def/c*sym classes with
     them. This is done so that the llvm target will be able to derive from
     the tcpu*def/sym classes without umpteen ifdefs, and it also means that
     the WPO can devirtualise everything because the c* variables are only
     initialised with one class type
   o replaced all t*def/t*sym constructor calls with c*def/c*sym constructor
     calls

e1332304ef * when converting Hi() to a shr node, convert the right shr const parameter to 
sinttype, instead of u32inttype. This:
  1) is consistent with what type conversion tshlshrnode.pass_typecheck inserts
     on the right side
  2) avoids the expensive conversion to 32-bit and the even more expensive
     performing the operation in 32-bit on i8086

d2b8275b99 + support for arbitrary encodings in readstr/writestr 
o set the code page of the temporary "text" file to utf-8 for writestr with
     unicodestring/widestring as destination, so that no data loss can occur
     (+ properly deal with cases whereby part of an utf-8 character is
      written to the textbuf in this case)
   o explicitly pass the code page of the destination ansistring for writestr
     with ansistring as destination and set it for the temporary "text" file
   o set the code page of the text file for readstr

9ad98a2c4d * Handle "SarInt64" always as internal procedure, introduced virtual method tinlinenode.first_sar that by default converts it into call to "fpc_sarint64" unless target CPU is 64-bit. This provides a point to insert target-specific optimizations.

dac8cbcefc * Handle assigned(x) expressions entirely in first pass by converting them to "x<>nil", indicate that procedure variables should not be called by setting nf_load_procvar flag (which is already used with typeconvnode for exactly the same purpose). This allows to generate better code when assigned(x) is used on right side of assigments. Mantis #24572.

b81f746e05 Inline Length(DynamicArray) 
Up until now a helperfunction was called at runtime. This change inlines
the whole code in the same way Length(AnsiString) works. As dynamic
arrays do not record their length but their highest index, an additional
"OP_ADD" is this case.
