Rather than having special rules like "intrinsics cannot
throw exceptions", just mark intrinsics with the nounwind

anything more than this anyway).

used unless the callsite is not known, since in
general they can do a better job than the versions
that take a function.  Also, users should no longer
call the version of getModRefBehavior that takes
both a function and a callsite.  To reduce the

My compiler complains that "x always evaluates to true"
in this call:

Result.IntVal = APInt(80, 2, x);

What is x?

uint16_t x[8];

I deduce that the APInt constructor being used is this one:

  APInt(uint32_t numBits, uint64_t val, bool isSigned = false);

rather than this one:

  APInt(uint32_t numBits, uint32_t numWords, const uint64_t bigVal[]);

Updated GenLibDeps.pl to employ "use strict" to help prevent uses of variables
that have not yet been defined.

Removed used of grep and sed when parsing the results of "nm". This was
originally motivated because if the user has specified options to grep using
the environment variable GREP_OPTIONS this could break the script. Piping
through grep/sed/sort/uniq is also (to my understanding) not necessary, and
the equivalent operations can be done much faster in the Perl script.

Using a crude benchmark, these changes resulted in a 3x speedup in the
execution of GenLibDeps.pl.

Add testcase for last llvm-gcc tweaks

Added quotes around $(NM_PATH) argument to GenLibDeps.pl script so that
the "-p" option is actually seen by nm (it was being dropped as it was
considered as separate argument to the Perl script).

Unbreak backwards compatibility with bytecode format.  Regression
introduced by this patch:

Fix PR1146: parameter attributes are longer part of
the function type, instead they belong to functions
and function calls.  This is an updated and slightly
corrected version of Reid Spencer's original patch.
The only known problem is that auto-upgrading of
bitcode files doesn't seem to work properly (see
test/Bitcode/AutoUpgradeIntrinsics.ll).  Hopefully
a bitcode guru (who might that be? :) ) will fix it.

Make LoopInfoBase more generic, in preparation for having MachineLoopInfo.  This involves a small interface change.

Add accessor for getting the underlying templated type.  This is necessary for templated LoopInfo.

Moving TGLexer.h from source to header file tab in TableGen project file

Don't redirect llvm-as's stderr to llvm-dis.

Remove unnecessary && from the RUN lines of this test.

Don't lower srem/urem X%C to X-X/C*C unless the division is actually
optimized. This avoids creating illegal divisions when the combiner is
running after legalize; this fixes PR1815. Also, it produces better
code in the included testcase by avoiding the subtract and multiply
when the division isn't optimized.

Add TGParser files to VStudio project files.  Removed generated files section from TableGen project file as it is no longer needed.  #Include <algorithm> directly from TGParser.cpp so it can see std::reverse.
