the block addresses) in a case like this:

#define _THIS_IP_  ({ __label__ __here; __here: (unsigned long)&&__here; })

void foo() {
  printf("%p\n", _THIS_IP_);
  printf("%p\n", _THIS_IP_);
  printf("%p\n", _THIS_IP_);
}

This is part of a futile attempt to not "break" bizzaro
code like this:

 l1:
  printf("l1: %p\n", &&l1);
  ++x;

  if( x < 3 ) goto l1;


Previously we'd fold &&l1 to 1, which is fine per our semantics
but not helpful to the user.

[AVX] Recorganize X86ShuffleDecode into its own library
(LLVMX86Utils.a) to break cyclic library dependencies between
LLVMX86CodeGen.a and LLVMX86AsmParser.a.  Previously this code was in
a header file and marked static but AVX requires some additional
functionality here that won't be used by all clients.  Since including
unused static functions causes a gcc compiler warning, keeping it as a
header would break builds that use -Werror.  Putting this in its own
library solves both problems at once.

A local live range is live in a single basic block. If such a range fails to

got it wrong: (1) a signed i8 multiply of 64 by 2 overflows, but the high part is
zero; (2) a signed i8 multiple of -128 by 2 overflows, but the high part is all
ones.

No one uses *-mingw64. mingw-w64 is represented as {i686|x86_64}-w64-mingw32. In llvm side, i686 and x64 can be treated as similar way.

lit/TestingConfig.py: Add the environment variable PRINTF_EXPONENT_DIGITS as workaround [PR6745] for mingw's tests. Danil Malyshev suggested this.

FIXME: It does not improve MSVC's issue.

[Danil Malyshev] Defining PRINTF_EXPONENT_DIGITS env is the suggested way to make MinGW ANSI/POSIX compatible. This is not only about the case we are discussing, but in general, I'd like to have explicitly defined compatibility mode for all the tests running on MinGW.
