e3ea46d1cb * disable SSE optimized Frac() for Win64; it has a much lower supported range than the existing Pascal implementation which uses Int() (in essence Round() and Trunc() should be corrected as well)

cad30aaee9 * x86_64: Modified fpc_exp_real so it does not use 'sahf' assembler instruction, which may be not present on early 64-bit capable x86 processors. Mantis #29583.

e4647ac133 - removed "nostackframe" from floating point helpers for llvm, as FPC 
doesn't handle nostackframe correctly in combination with extended
    parameters on x86 (with or without llvm)

6909523b70 * handle atan, sqrt, ln, sin and cos in the x86 RTL for llvm 
o there are llvm intrinsics for all of these except for atan,
      but these obey "the same rules as the equivalent libc functions"
      and I first have to investigate whether these libc functions
      behave the same as our FPC implementations

f456bb3a25 * Re-implement ln(x) also for x87-based x86_64 targets (counterpart of r27367,r27518,r27552,r27553 for i386 target).

b16c6f8ced * i386 and x86_64 changes for Delphi compatibility: 
* 'mxcsr' variable made public and renamed to DefaultMXCSR.
  * GetSSECSR and SetSSECSR renamed to GetMXCSR and SetMXCSR, respectively. Previous names continue to exist as deprecated aliases.

90d66595c2 * typecheck_real_to_currency: generate inline round() node instead of direct call to fpc_round_real, this allows target-specific processing to take place and possibly emit more efficient code. 
* Provide x86_64 SSE versions of fpc_trunc_real and fpc_round_real, strictly they are not necessary after the above change to code generation, but it still reduces size of system unit by avoiding compilation of related generic code.

4a3c7f7ef4 * Get8087CW: use fixed stack.
