to load an immediate that does not fit into 16-bit. Also, take into
consideration the global base register slot on the stack when computing the
stack size.

compute the size of basic blocks in a function. Also, define a function which
emits a series of instructions to load an immediate.

Long-branches need access to the global base register to get the destination
address.

This is the first of a series of patches which implements long branch expansion
for MIPS.

delay slot filler pass of MIPS, per suggestion of Jakob Stoklund Olesen.

This change, along with the fix in r158154, enables machine verification
to be run after delay slot filling.

(add v0, (add v1, abs_lo(tjt))) => (add (add v0, v1), abs_lo(tjt))

"tjt" is a TargetJumpTable node.

Fix intrinsics for XOP frczss/sd instructions. These instructions only take one source register and zero the upper bits of the destination rather than preserving them.

On the POWER7, adds and logical operations can also be handled
in the load/store pipelines. We'll call these IntSimple.

POWER4 is a 64-bit CPU (better matched to the 970).
The g3 is really the 750 (no altivec), the g4+ is the 74xx (not the 750).

Original commit message:
Move PPC host-CPU detection logic from PPCSubtarget into sys::getHostCPUName().

Both the new Linux functionality and the old Darwin functions have been moved.
This change also allows this information to be queried directly by clang and
other frontends (clang, for example, will now have real -mcpu=native support).

llvm-svn: 158349

This commit broke most of the PowerPC unit tests when running on
Intel/Apple.

llvm-svn: 158345

Both the new Linux functionality and the old Darwin functions have been moved.
This change also allows this information to be queried directly by clang and
other frontends (clang, for example, will now have real -mcpu=native support).

The PPC target feature gpul (IsGigaProcessor) was only used for one thing:
To enable the generation of the MFOCRF instruction. Furthermore, this
instruction is available on other PPC cores outside of the G5 line. This
feature now corresponds to the HasMFOCRF flag.

No functionality change.

llvm-svn: 158323

llvm-svn: 158322

This is necessary on Linux and supported on Darwin, see PR2604.

llvm-svn: 158315

This functionality mirrors that available on PPC/Darwin.

llvm-svn: 158314

No functional change; these will be used by upcoming scheduler enhancements.

llvm-svn: 158313

We turned off the CMN instruction because it had semantics which we weren't
getting correct. If we are comparing with an immediate, then it's okay to use
the CMN instruction.

Over the entire test-suite, this has an insignificantly negative average
performance impact, but reduces some of the worst slowdowns from the
anti-dep. change (r158294).

Largest speedups:
SingleSource/Benchmarks/Stanford/Quicksort - 28%
SingleSource/Benchmarks/Stanford/Towers - 24%
SingleSource/Benchmarks/Shootout-C++/matrix - 23%
MultiSource/Benchmarks/SciMark2-C/scimark2 - 19%
MultiSource/Benchmarks/MiBench/automotive-bitcount/automotive-bitcount - 15%
(matrix and automotive-bitcount were both in the top-5 slowdown list from the
anti-dep. change)

Largest slowdowns:
MultiSource/Benchmarks/McCat/03-testtrie/testtrie - 28%
MultiSource/Benchmarks/mediabench/gsm/toast/toast - 26%
MultiSource/Benchmarks/MiBench/automotive-susan/automotive-susan - 21%
