Hal Finkel 0a750c5cd8 [PowerPC] Mark zext of a small scalar load as free
This initial implementation of PPCTargetLowering::isZExtFree marks as free
zexts of small scalar loads (that are not sign-extending). This callback is
used by SelectionDAGBuilder's RegsForValue::getCopyToRegs, and thus to
determine whether a zext or an anyext is used to lower illegally-typed PHIs.
Because later truncates of zero-extended values are nops, this allows for the
elimination of later unnecessary truncations.

Fixes the initial complaint associated with PR22120.

examples Manually specify the folder that Kaleidescope should reside in for CMake-produced solutions that care about such things (like MSVC). This takes the Kaleidescope target out of the root solution folder and places it into the Examples folder where it belongs. 2015-01-07 14:26:07 +00:00

the license agreement found in LICENSE.txt.

Please see the documentation provided in docs/ for further
assistance with LLVM, and in particular docs/GettingStarted.rst for getting
started with LLVM and docs/README.txt for an overview of LLVM's
documentation setup.
