gcc : ChangeLog fold-const.c
Log message:
* fold-const.c (fold) <PLUS_EXPR>: Canonicalize X + -C as X - C for
floating point additions, to keep real immediate constant positive.
<MINUS_EXPR>: For floating point subtractions, only transform X - -C
into X + C, and leave positive real constants as X - C.
