[Mingw-w64-public] [PATCH] crt: Add an ldexpl function for arm and arm64

[Martin Storsjö]

Since long double just is normal double on arm and arm64, just
call the normal ldexp function.

[Martin Storsjö]

For lib64, this only adds a few new functions.

Also provide it for arm64.

[Mingw-w64-public] Compile failure due to GCC builtin

[Zebediah Figura]

Hello,

While attempting to compile the CRT according to the instructions on
sourceforge [1], I ran into a compile error:

In file included from
/usr/local/lib/gcc/i386-w64-mingw32/8.0.0/include/x86intrin.h:74,
 from /usr/local/i386-w64-mingw32/include/intrin.h:73,
 from ../intrincs/rdtsc.c:7:
/usr/local/lib/gcc/i386-w64-mingw32/8.0.0/include/xsaveintrin.h:60:1:
error: conflicting types for ‘_xgetbv’
 _xgetbv (unsigned int __A)
 ^~~
In file included from /usr/local/i386-w64-mingw32/include/intrin.h:41,
 from ../intrincs/rdtsc.c:7:
/usr/local/i386-w64-mingw32/include/psdk_inc/intrin-impl.h:1784:18:
note: previous definition of ‘_xgetbv’ was here
 unsigned __int64 _xgetbv(unsigned int index)
  ^~~

The problem seems to be that mingw's intrin-impl.h defines _xgetbv,
which is included in recent gcc. Since gcc doesn't provide
__has_builtin, we redefine this type. I don't know what the usual method
of dealing with this is, if there is one. Could someone illuminate me as
to the correct way to fix this? Alternatively, is there something wrong
with my build setup?
