where both symbols are "local", that is non-external symbols, and there is
no "base" for the symbols used in the expression, that is the section has
no non-temporary symbols. This case looks like this:
% cat local_reloc_A-B.s
.long 0
LB: .long 1
.long LA - LB - 4
.long 2
LA: .long 3
which llvm-mc will not encode without this patch, generates a "unsupported
local relocations in difference" error, but the Darwin assembler will
encode with relocation entries like this:
% otool -rv a.out l.out
a.out:
Relocation information (__TEXT,__text) 2 entries
address pcrel length extern type scattered symbolnum/value
00000008 False long False SUB False 1 (__TEXT,__text)
00000008 False long False UNSIGND False 1 (__TEXT,__text)
which is very similar to what is encoded when the symbols don't have the
leading 'L' and they are not temporary symbols. Which llvm-mc and the
Darwin assembler will encoded like this:
Relocation information (__TEXT,__text) 2 entries
address pcrel length extern type scattered symbolnum/value
00000008 False long True SUB False B
00000008 False long True UNSIGND False A
This is the missing relocation encoding needed to allow the Mach-O x86
Dwarf file and line table to be emitted. So this patch also removes the
TODO from the if() statement in MCMachOStreamer::Finish() that didn't
call MCDwarfFileTable::Emit() for 64-bit targets.

force it to be a constant instead of emitting with EmitScalarExpr. In
-ftrapv mode, they are not the same.

LiveInterval::MergeValueNumberInto instead of trying to extend LiveRanges and
getting it wrong.
This fixed PR8249 where a valno with a multi-segment live range was defined by
an identity copy created by RemoveCopyByCommutingDef. Some of the live
segments disappeared.

For example, on:
#include <emmintrin.h>
int foo(int N) {
__m128i white2;
white2 = _mm_slli_si128(white2, N);
return 0;
}
we used to get:
fatal error: error in backend: Cannot yet select: intrinsic %llvm.x86.sse2.psll.dq
now we get:
/Users/sabre/t.c:4:11: error: argument to '__builtin_ia32_pslldqi128' must be a
constant integer
white2 = _mm_slli_si128(white2, N);

The change most likely resulted from an update from the llvm tot with a newer clang.

To not skip long running tests, pass '-l' to the test driver (dotest.py).
An example:
@unittest2.skipIf(TestBase.skipLongRunningTest(), "Skip this long running test")

o Added a long running disassemble test to the foundation directory, which iterates
the code symbols from Foundation.framework and kicks off a disassemble command for
for the named function symbol. Found a crasher: rdar://problem/8504895.
o Plus added/updated some comments for the TestBase class.

stick with a constant estimate of 90% (branch predictors are good!), but we might find that we want to provide
more nuanced estimates in the future.

and add it back in with an updated comment about when would be a good time
to revisit.
