Chris Lattner 58aff8fb57 fix PR7105 by enumerating MDNodes on all @llvm.foo
function calls, not just recognized intrinsics.

David Greene 103d4b43e9 Fix PR6875:
This includes a patch by Roman Divacky to fix the initial crash.

Move the actual addition of passes from *PassManager::add to
*PassManager::addImpl.  That way, when adding printer passes we won't
recurse infinitely.

Finally, check to make sure that we are actually adding a FunctionPass
to a FunctionPassManager before doing a print before or after it.
Immutable passes are strange in this way because they aren't
FunctionPasses yet they can be and are added to the FunctionPassManager.

Duncan Sands 8815f38312 Fix a problem exposed by my previous commit and noticed by a release-asserts
buildbot: the debugging and non-debugging versions of getFunction were not
functionally equivalent: the non-debugging version wrongly assumed that if a
metadata operand was not metadata, then it had a non-null containing function.
This is not true, since the operand might be a global value, constant etc.

Duncan Sands c2928c6ef5 Fix a variant of PR6112 found by thinking about it: when doing
RAUW of a global variable with a local variable in function F,
if function local metadata M in function G was using the global
then M would become function-local to both F and G, which is not
allowed.  See the testcase for an example.  Fixed by detecting
this situation and zapping the metadata operand when it occurs.

Dan Gohman a2414ea190 Remove the API compatibility layer which converted add, sub, and mul
to fadd, fsub, and fmul, when used with a floating-point type. LLVM
has supported the new instructions since 2.6, so it's time to get
on board.

Duncan Sands 76d6217906 Verify metadata harder. In particular, check that module

Chris Lattner 450e29cb4c fix PR6112 - When globalopt (or any other pass) does RAUW(@G, %G),
metadata references in non-function-local MDNodes should drop to 
null.

Eric Christopher 64831c6a4c Remove the palignr intrinsics now that we lower them to vector shuffles,
shifts and null vectors. Autoupgrade these to what we'd lower them to.

Eric Christopher 7258dcd77f Revert 101465, it broke internal OpenGL testing.
Probably the best way to know that all getOperand() calls have been handled
is to replace that API instead of updating.

Gabor Greif f375520f7b reapply r101434
with a fix for self-hosting

rotate CallInst operands, i.e. move callee to the back
of the operand array

the motivation for this patch are laid out in my mail to llvm-commits:
more efficient access to operands and callee, faster callgraph-construction,
smaller compiler binary

Daniel Dunbar d33749b4a9 VMCore: Add Type::getIntN[Ptr]Ty, which are the obvious generic forms of

Chris Lattner 1e45789ee0 introduce a new recoverable error handling API to LLVMContext
and use it in one place in inline asm handling stuff.  Before
we'd generate this for an invalid modifier letter:

$ clang asm.c -c -o t.o
fatal error: error in backend: Invalid operand found in inline asm: 'abc incl    ${0:Z}'
INLINEASM <es:abc incl    ${0:Z}>, 10, %EAX<def>, 2147483657, %EAX, 14, %EFLAGS<earlyclobber,def,dead>, <!-1>


Now we generate this:

$ clang asm.c -c -o t.o
error: invalid operand in inline asm: 'incl    ${0:Z}'
asm.c:3:12: note: generated from here
  __asm__ ("incl    %Z0" : "+r" (X));
           ^
1 error generated.

This is much better but still admittedly not great ("why" is the operand 
invalid??), codegen should try harder with its diagnostics :)

Mon P Wang c576ee9040 Reapply address space patch after fixing an issue in MemCopyOptimizer.
Added support for address spaces and added a isVolatile field to memcpy, memmove, and memset,
e.g., llvm.memcpy.i32(i8*, i8*, i32, i32) -> llvm.memcpy.p0i8.p0i8.i32(i8*, i8*, i32, i32, i1)

David Greene 9b063df40b Ok, third time's the charm. No changes from last time except the CMake
source addition.  Apparently the buildbots were wrong about failures.

---

Add some switches helpful for debugging:

-print-before=<Pass Name>

Dump IR before running pass <Pass Name>.

-print-before-all

Dump IR before running each pass.

-print-after-all

Dump IR after running each pass.

These are helpful when tracking down a miscompilation.  It is easy to
get IR dumps and do diffs on them, etc.

To make this work well, add a new getPrinterPass API to Pass so that
each kind of pass (ModulePass, FunctionPass, etc.) can create a Pass
suitable for dumping out the kind of object the Pass works on.

David Greene 8f32cb9fce Let's try this again. Re-apply 100143 including an apparent missing
<string> include.  For some reason the buildbot choked on this while my
builds did not.  It's probably due to a difference in system headers.
