It is not a good idea to have data member's name match argument's name. In fact, it is a simple receipe to waste an hour or so.

Use atomic operations when accessing statistics, and make the lazy initialization of statistics actually threadsafe.

llvm-svn: 74005

llvm-svn: 74004

Make timers threadsafe again.  This isn't quite as nice as I'd hoped (it uses locking rather than atomic arithmetic),
but should work on all the platforms we care about.

I might revisit this if a totally awesome way to do it occurs to me.

instructions, which implies that there is an explicit memory operand.  There is
(however) no explicit memory operand; although this is a store, the only memory
operand is implicit, indicated by DS:EDI.  This causes the table-generation code
for the disassembler to report an error."

Add IsThumb1Only to most 16-bit thumb instructions since we want to isel 32-bit instructions when they are available.

Use 64-bit integer counters for tracking time, rather than doubles.  This will be more atomic op friendly.

cleans up the CMake-based build system a bit. Started by a patch from
Xerxes Rånby.

also some contribution from Jim Grosbach, Bob Wilson, and Evan Cheng.

I've done my best to consolidate the patches with those that were done by
Viktor Kutuzov and Anton Korzh from Access Softek, Inc. Let me know if missed
anything. I've completely reorganized the thumb2 td file, made more extensive
uses of multiclass, etc.

Test cases will be contributed later after I re-organize what's in svn first.

Fold the add (ptr, offset) into ptr[offset] only if the offset is small enough. movwi and moviw allow value of 5-bits only (i.e. 32).

Only pad when the section size > 0 and move the code that deals
with globals initializers to a place we know for sure the global
is initialized.

This is still a work in progress but most of the NEON instruction set

is concerned).
