access to bits). Use them in place of float and
double interfaces where appropriate.
First bits of x86 long double constants handling
(untested, probably does not work).

Use APFloat in UpgradeParser and AsmParser.
Change all references to ConstantFP to use the
APFloat interface rather than double. Remove
the ConstantFP double interfaces.
Use APFloat functions for constant folding arithmetic
and comparisons.
(There are still way too many places APFloat is
just a wrapper around host float/double, but we're
getting there.)

This also changes the syntax for llvm.bswap, llvm.part.set, llvm.part.select, and llvm.ct* intrinsics. They are automatically upgraded by both the LLVM ASM reader and the bitcode reader. The test cases have been updated, with special tests added to ensure the automatic upgrading is supported.

Note: FastDSE now equals or exceeds the results of old DSE on all of SPEC2000 and SPEC2006. Unless major problems
show up in the testers, it will likely completely replace old DSE in the near future.

right so there is no need to duplicate logic, just use the values the makefile
provides.
Eliminate some redundnt -D options from the output.
Fix the help output so it fits on 80 cols.

--enable-expensive-checks allows the developer to enable runtime
checking that can greatly increase compile time. Currently it only
turns on _GLIBCXX_DEBUG. Other expensive debugging checks added later
should be controlled by this configure option.
This patch also updates llvm-config with a --cppflags option to inform
llvm-gcc how to build itself so that it is compatible with an llvm that
was built with _GLIBCXX_DEBUG.

Use a better determinator for identifying constant array initializers that
are or are not zero terminated and generate code appropriately.
llvm-svn: 37720
Use SmallPtrSet instead of std::vector to eliminate duplicate uses in a
function generated with -gen-function. This prevents the output from having
multiple duplicate declarations of constants and gvals.
llvm-svn: 37616
When printing the uses of a function (-gen-function only), make sure to
include the constants referenced by intializers of global variables.
