Andrew Trick a3f9043196 SCEV: Handle a corner case reducing AddRecExpr * AddRecExpr 
If integer overflow causes one of the terms to reach zero, that can
force the entire expression to zero.

Jim Ingham 3ee12ef26e We were accessing the ModuleList in the target without locking it for tasks like 
setting breakpoints.  That's dangerous, since while we are setting a breakpoint,
the target might hit the dyld load notification, and start removing modules from
the list.  This change adds a GetMutex accessor to the ModuleList class, and
uses it whenever we are accessing the target's ModuleList (as returned by GetImages().)

Richard Trieu 01cf09302d Add new -Wunique-enum which will warn on enums which all elements have the 
same value and were initialized with literals.  Clang will warn on code like
this:

Bob Wilson 33e5188c27 Add an insertPass API to TargetPassConfig. <rdar://problem/11498613> 
Besides adding the new insertPass function, this patch uses it to
enhance the existing -print-machineinstrs so that the MachineInstrs
after a specific pass can be printed.

Jakob Stoklund Olesen 850ef99516 Use MCRegUnitIterator to compute regsOverlap(). 
The register unit lists are typically much shorter than the register
overlap lists, and the backing table for register units has better cache
locality because it is smaller.

This makes llc about 0.5% faster. The regsOverlap() function isn't that hot.

llvm-svn: 157651
 2012-05-29 23:40:02 +00:00
Jakob Stoklund Olesen 7f381bd26d Emit register unit lists for each register. 
Register units are already used internally in TableGen to compute
register pressure sets and overlapping registers. This patch makes them
available to the code generators.

The register unit lists are differentially encoded so they can be reused
for many related registers. This keeps the total size of the lists below
200 bytes for most targets. ARM has the largest table at 560 bytes.

Add an MCRegUnitIterator for traversing the register unit lists. It
provides an abstract interface so the representation can be changed in
the future without changing all clients.

Also add a test scenario for that.

Benjamin Kramer ef479ea854 Add intrinsics, code gen, assembler and disassembler support for the SSE4a extrq and insertq instructions. 
This required light surgery on the assembler and disassembler
because the instructions use an uncommon encoding. They are
the only two instructions in x86 that use register operands
and two immediates.

Lang Hames e256f71937 Clear the entering, exiting and internal ranges of a bundle before collecting

the bundle.
