Ian Lance Taylor a171ac0380 compiler: handle >32bit exponent in Ldexp
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.

See ../README.

This is the runtime support library for the Go programming language.
This library is intended for use with the Go frontend.

This library should not be stripped when it is installed.  Go code
relies on being able to look up file/line information, which comes
from the debugging info using the libbacktrace library.

The library has only been tested on GNU/Linux using glibc, and on
Solaris.  It should not be difficult to port to other operating
systems.

Directories:

go
  A copy of the Go library from http://golang.org/, with several
  changes for gccgo.

runtime
  Runtime functions, written in C, which are called directly by the
  compiler or by the library.
