22696c10f0 check that terminators only occur at the end of a block. This catches the
common problem of putting two terminators in the same block.  I can't write
a testcase for this because the .ll parser rejects this before the verifier
can, but this can occur when generating IR.

allowed on the vararg arguments of a call.

e55a5806ac Do not allow attributes beyond a function's last
parameter, even if it is a varargs function.  Do
allow attributes on the varargs part of a call,
but not beyond the last argument.  Only allow
selected attributes to be on the varargs part of
a call (currently only 'byval' is allowed).  The
reasoning here is that most attributes, eg inreg,
simply make no sense here.

fd975e4b3d The transform that tries to turn calls to bitcast functions into
direct calls bails out unless caller and callee have essentially
equivalent parameter attributes.  This is illogical - the callee's
attributes should be of no relevance here.  Rework the logic, which
incidentally fixes a crash when removed arguments have attributes.

bc10247769 Get the verifier to check attributes on calls as well
as on functions.  Make it verify invokes and not just
ordinary calls.  As a (desired) side-effect, it is no
longer legal to have call attributes on arguments that
are being passed to the varargs part of a varargs
function (llvm-as drops them on the floor anyway).

a608afb52e Change the PointerType api for creating pointer types. The old functionality of PointerType::get() has become PointerType::getUnqual(), which returns a pointer in the generic address space. The new prototype of PointerType::get() requires both a type and an address space.

3602011bec 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.

114968a3e8 Fix PR1816. If a bitcast of a function only exists because of a
trivial difference in function attributes, allow calls to it to
be converted to direct calls.  Based on a patch by Török Edwin.
While there, move the various lists of mutually incompatible
parameters etc out of the verifier and into ParameterAttributes.h.

fc061f4e20 Don't barf on empty basic blocks. Do not rely on assert
doing something - this needs to work for release builds
too.  I chose to just abort rather than following the
fancy logic of abortIfBroken, because (1) it is a pain
to do otherwise, and (2) nothing is going to work if the
module is this broken.

fa3a5915b1 Fix for PR1633: Verifier doesn't fully verify GC intrinsics
LLVM now enforces the following prototypes for the write barriers:

<ty>* @llvm.gcread(<ty2>*, <ty>**)
void @llvm.gcwrite(<ty>*, <ty2>*, <ty>**)

And for @llvm.gcroot, the first stack slot is verified to be an alloca or a 
bitcast of an alloca.

Fixes test/CodeGen/Generic/GC/lower_gcroot.ll, which violated these.

00e56b0e81 This is the patch to provide clean intrinsic function overloading support in LLVM. It cleans up the intrinsic definitions and generally smooths the process for more complicated intrinsic writing. It will be used by the upcoming atomic intrinsics as well as vector and float intrinsics in the future.
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.

b0eeb23ce8 The InReg parameter attribute is valid on function results. The llvm-gcc-4.0
