Duncan Sands a071c82900 Fix PR9820: a read-only call differs from a load in that a load doesn't
return the pointer being dereferenced, it returns the pointee, but a call
might return the pointer itself.

Andrew Trick 3dc73aae5e ARM post RA scheduler compile time fix.
BuildSchedGraph was quadratic in the number of calls in the basic
block. After this fix, it keeps only a single call at the top of the
DefList so compile time doesn't blow up on large blocks. This reduces
postRA sched time on an external test case from 81s to 0.3s.  Although
r130800 (reduced ARM register alias defs) also partially fixes the
issue by reducing the constant overhead of checking call interference
by an order of magnitude.

Fixes <rdar://problem/7662664> very poor compile time with post RA scheduling.

I tested both gdb on a bootstrapped clang and and the gdb testsuite on OS X (snow leopard)
and both are happy using __eh_frame.

Galina Kistanova b93a130120 Many LLVM tests relies on standard output stream be in the binary mode. Which is not always the case (on Windows in particular). The patch adds a test to verify that the standard output stream is actually in the binary mode.

Bill Wendling a48b1375df Remove a flag that would set the ".eh" symbol as .globl. MachO was the only one
who used this flag, and it now emits CFI and doesn't emit this anymore. All
other targets left this flag "false".

Jakob Stoklund Olesen 1d3854d583 Disable physical register coalescing by default.
Joining physregs is inherently dangerous because it uses a heuristic to avoid
creating invalid code. Linear scan had an emergency spilling mechanism to deal
with those rare cases. The new greedy allocator does not.

The greedy register allocator is much better at taking hints, so this has almost
no impact on code size and quality. The few cases where it matters show up as
unit tests that now have -join-physregs enabled explicitly.

Jakob Stoklund Olesen 369bddf5ad Fix a batch of x86 tests to be coalescer independent.
Most of these tests require a single mov instruction that can come either before
or after a 2-addr instruction. -join-physregs changes the behavior, but the
results are equivalent.

Bill Wendling 2a40131f6b SjLj EH could produce a machine basic block that legitimately has more than one
landing pad as its successor.

SjLj exception handling jumps to the correct landing pad via a switch statement
that's generated right before code-gen. Loosen the constraint in the machine
instruction verifier to allow for this. Note, this isn't the most rigorous check
since we cannot determine where that switch statement came from. But it's
marginally better than turning this check off when SjLj exceptions are used.

Nick Lewycky 892e9934ba Create the parent directories to place the .gcda files in if they don't exist.
