Stuart Hastings 51d696766c An imminent fix to the x86_64 byval logic will expose a flaw in the
x86_64 sibcall logic.  I've filed PR9943 for the sibcall problem, and
this patch alters the testcase to work around the flaw.  When PR9943
is fixed, this patch should be reverted.

Greg Clayton 1c870d6e9f One more fix to:
bool SectionLoadList::ResolveLoadAddress (addr_t load_addr, Address &so_addr) const;

Where if the address is in the last map entry, we need to look it up correctly.
My previous fix was incorrect where it looked in the first if there were
no addresses in the map that were > load_addr. Now we correctly look in the
last entry if our std::map::lower_bound search returns the end of the 
collection.

Duncan Sands 27bd0df352 Now that SrcBits and DestBits always represent the primitive size, rather
than either the primitive size or the element primitive size (in the case
of vectors), simplify the vector logic.  No functionality change.  There
is some distracting churn in the patch because I lined up comments better
while there - sorry about that.

Duncan Sands 7f64656d21 Tighten up checking of the validity of casts. (1) The IR parser would
happily accept things like "sext <2 x i32> to <999 x i64>".  It would
also accept "sext <2 x i32> to i64", though the verifier would catch
that later.  Fixed by having castIsValid check that vector lengths match
except when doing a bitcast.  (2) When creating a cast instruction, check
that the cast is valid (this was already done when creating constexpr
casts).  While there, replace getScalarSizeInBits (used to allow more
vector casts) with getPrimitiveSizeInBits in getCastOpcode and isCastable
since vector to vector casts are now handled explicitly by passing to the
element types; i.e. this bit should result in no functional change.

llvm-svn: 131532
2011-05-18 09:21:57 +00:00
Duncan Sands a8514535a4 Teach getCastOpcode about element-by-element vector casts. For example, "trunc"
can be used to turn a <4 x i64> into a <4 x i32> but getCastOpcode would assert
if you passed these types to it.  Note that this strictly extends the previous
functionality: if getCastOpcode previously accepted two vector types (i.e. didn't
assert) then it still will and returns the same opcode (BitCast).  That's because
before it would only accept vectors with the same bitwidth, and the new code only
touches vectors with the same length.  However if two vectors have both the same
bitwidth and the same length then their element types have the same bitwidth, so
the new logic will return BitCast as before.

Tanya Lattner 48b182c3a4 In r131488 I misunderstood how VREV works. It splits the vector in half and splits each half. Therefore, the real problem was that we were using a VREV64 for a 4xi16, when we should have been using a VREV32.
Updated test case and reverted change to the PerfectShuffle Table.

Charles Davis 8d9c99042f Implement the Win64 EH directive methods for the assembly language streamer.
GAS has no such directives (not even mingw-w64 GAS has them), so I took
creative license with their names in assembly. I prefixed them all with
"w64_" to avoid namespace collisions, for example. If I discover that GAS
has taken a different approach, I'll change ours to match.

Charles Davis 384041d0dc While thinking about how to know where the functions' boundaries are for
the purposes of the Win64 EH tables, I realized we had no way to tell where
the function ends. (MASM bounds functions with PROC and ENDP keywords.)
Add a directive to delimit the end of the function, and rename the 'frame'
directive to more accurately reflect its duality with the new directive.

Jakob Stoklund Olesen 595a47d462 Properly shrink live ranges after deleting dead copies. Clean up after all joined copies.
LiveInterval::shrinkToUses recomputes the live range from scratch instead of
removing snippets. This should avoid the problem with dangling live ranges.

Leave physreg identity copies alone. They can be created when joining a virtreg
with a physreg. They don't affect register allocation, and they will be removed
by the rewriter.

Alexis Hunt e77a28f7e1 Implement an additional fix for infinite recursion of deleted special
member functions by making sure that they're on the record before
checking for deletion.

Also make sure source locations are valid to avoid crashes.

Unfortunately, the declare-all-implicit-members approach is still
required in order to ensure that dependency loops do not result in
incorrectly deleting functions (since they are to be deleted at the
declaration point per the standard).

Greg Clayton cd482e359e Added a way to resolve an load address from a target:
bool
Address::SetLoadAddress (lldb::addr_t load_addr, Target *target);

Added an == and != operator to RegisterValue.

Modified the ThreadPlanTracer to use RegisterValue objects to store the
register values when single stepping. Also modified the output to be a bit
less wide.

Fixed the ABIMacOSX_arm to not overwrite stuff on the stack. Also made the
trivial function call be able to set the ARM/Thumbness of the target 
correctly, and also sets the return value ARM/Thumbness.

Fixed the encoding on the arm s0-s31 and d16 - d31 registers when the default
register set from a standard GDB server register sets.

Eli Friedman 96254a0d53 Start trying to make InstCombine preserve more debug info. The idea here is to set the debug location on the IRBuilder, which will be then right location in most cases. This should magically give many transformations debug locations, and fixing places which are missing a debug location will usually just means changing the code creating it to use the IRBuilder.
As an example, the change to InstCombineCalls catches a common case where a call to a bitcast of a function is rewritten.

Chris, does this approach look reasonable?

Alexis Hunt 2430a6fb91 Force declaration of implicit members in C++0x mode.
I hear at least one person crying out in anguish, but it's unfortunately
necessary to avoid infinite loops with mutually dependent constructors
trying to call each other and determine if they are deleted.

It might be possible to go back to the old behavior if we can implement
part-of-file lookups efficiently, or if a solution is discovered by
which we can safely detect and avoid infinite recusion.
