  isn't incremented.

This is the initial check-in for adding register scavenging to PPC. (Currently,
PPC-64 doesn't work.) This also lowers the spilling of the CR registers so that
it uses a register other than the default R0 register (the scavenger scrounges
for one). A significant part of this patch fixes how kill information is
handled.

by using the new convertFromAPInt directly.

Add a method to APFloat to convert directly from APInt.

Added option -align-loops=<true/false> to disable loop aligner pass.

Update testcase.

Interface of getByValTypeAlignment differed between
generic & x86 versions; change generic to follow x86
and improve comments.  Add PPC version (not right
for non-Darwin.)

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47734 91177308-0d34-0410-b5e6-96231b3b80d8

Make llvm-ar behave like ar, if you create an empty archive, ar creates an empty archive.  llvm-ar would not generate an output file in this case

Initialize TextAlignFillValue. Fix revision 47703.

Avoid collisions in value names.

Run 'svn info' in the C locale. Also appropriately escape spaces and ? for gawk in darwin.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47723 91177308-0d34-0410-b5e6-96231b3b80d8

Fix an assertion message.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47722 91177308-0d34-0410-b5e6-96231b3b80d8

add a note

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47720 91177308-0d34-0410-b5e6-96231b3b80d8

Document that the shuffle mask may contain undef
values.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47719 91177308-0d34-0410-b5e6-96231b3b80d8

Simplify and clean up "update" target. Also
add an SVN-UPDATE-OPTIONS variable that controls
the update behaviour. This allows to go to a common
older revision of all svn directories:

  gmake update SVN-UPDATE-OPTIONS=-r47717

would rewind both llvm and clang to a common
revision (if clang is checked out into the llvm
tree).

Now that targets are serialized, introduce
two new convenience targets:

- update: svn update toplevel and try hard
          to locate updatable subdirectories
using cunning tricks
- happiness: update then build and test

so what one wants to do now is:
  nice gmake --jobs happiness

Have fun!

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47716 91177308-0d34-0410-b5e6-96231b3b80d8

Treat all targets serially at the toplevel. This allows
to specify
  nice gmake --jobs all check
and go to lunch, while a multiprocessor machine
will build everything using spare resources
and check the result thereafter.
Since concurrency of make is not restricted
in subdirectories, this should be a nearly
optimal way to do it.

Also teach the user about a configure switch.

Fix llvm.org/bugs/show_bug.cgi?id=2104 by ordering lexicographically what gets printed. Be const-correct in PrintResults and uninline it too

Set to default: x86 no longer fold and into test if it has more than one use.
