c16d232c3a fcl-db: bufdataset: when updates in update buffers are canceled, reverted records must be correctly restored to all active indexes not only in current (then other indexes remains in inconsistent state) 
Bug #25314

141b2f7066 * arcsin and arccos: improve accuracy at small arguments by replacing sqr(1-x*x) with sqr((1-x)*(1+x)). 
* arcosh: likewise, error near 1.0 decreases approx. from 80*eps to 4*eps.
* artahn: improve accuracy by replacing ln(x+1) with lnxp1(x).

636736dda6 * log2() and log10(): replaced division by ln(base) with multiplication by reciprocal constant, this executes faster and somehow provides slightly better accuracy.

c7213b7ff1 - Math unit: don't raise EInvalidArgument exception in general math functions, this is Delphi-compatible. Delphi raises EInvalidArgument only in statistical/financial functions; general math functions execute code which causes EInvalidOp raised by hardware (or low-level system routines).

3ce0b33302 * Win64 SEH: when creating a finalization procedure, put its def into the same symtable with sym. By default, defs are added into symtablestack.top, which may be set to something temporary like exceptsymtable. In such cases it is possible that def is destroyed before sym, leaving sym with invalid pointers.

897c8b8f7b * Cleanup fpc_trunc_real implementation. 
* For single-precision variant, truncate to 64 bits instead of 32, since this how trunc()/round() are defined.
* Do not access float64 as int64, doing so would break on ARM hardfloat after r26010.

dc432918da + enabled the use of the DIV/IDIV instruction for 16-bit div/mod on i8086 
* ti8086.moddivnode.pass_generate_code: use cg.a_op_const_reg, instead of
  emit_const_reg, in order to support generating plain 8086/8088 code
  (shr/shl/sar reg,const is 186+ if const is >= 2).

c1cec52897 * fixed alignment of bitpacked arrays of ordinals/enums: the prevous code 
always returned the alignment of enum/ordinal by itself, which could be
    either bigger or smaller than what was required
  * for non-bitpacked regular arrays, always use the alignment of the elements
    instead of sometimes the natural alignment of the size of the elements
    (which can be different)
