bfde7d6b9e As comments said, for negative value, the arithmetic 
over-shift-right should return -1. So here it should be signed-extended,
when bitwidth larger than 64.

79f82f9fd5 Check that APFloat::convert is not trying to target 
ppc long double, which doesn't work.

This may break some stuff temporarily, but I want to
avoid the propagation of code that assumes this works.

038112a4e0 Change the MemoryBuffer::getFile* methods to take just a pointer to the 
start of a filename, not a filename+length.  All clients can produce a
null terminated name, and the system api's require null terminated 
strings anyway.


git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@49041 91177308-0d34-0410-b5e6-96231b3b80d8

11da4cf25c Reimplement MemoryBuffer::getFile with three enhancements: 
1) stop using MappedFile.
2) if profitable use the sys::path::MapInFilePages api to
   read the file.
3) otherwise fallback to read.

When sys::path::MapInFilePages is implemented, this provides
several benefits:

#1: this avoids fragmenting memory for small files.
#2: this avoids extraneous stat calls when the file size is known.
#3: this only keeps the file descriptor open while reading the 
    file, not for the duration of the lifetime of the memory 
    buffer.  This fixes a serious clang FD 'leak' problem.

I believe that this will work on a win32 machine, but I don't have
one to test on.  I'd appreciate it if someone could check.

a7750c1142 Change DiffFilesWithTolerance to be written in terms of MemoryBuffer, 
not an mmapped file.  This more closely matches its requirements and
provides an implicitly null terminated buffer, something this
routine had to emulate itself before.
