compiler: handle >32bit exponent in Ldexp · a171ac03
Libgo's implementation of math.Ldexp declared the libc "ldexp" as taking an 'int' exponent argument, which is not quite right for 64-bit platforms (exp arg is always int32); this could yield incorrect results for exponent values outside the range of Minint32/Maxint32. Fix by upating the type for the libc version of ldexp, and adding guards to screen for out-of-range exponents. Fixes #21323. Reviewed-on: https://go-review.googlesource.com/54250 From-SVN: r250992
