Tom Stellard 624741fded R600: Fix segfault in R600TextureIntrinsicReplacer
This pass was segfaulting when it ran into a non-intrinsic function
call.  Function calls are not supported, so now instead of segfaulting,
we will get an assertion failure with a nice error message.

I'm not sure how to test this using lit.

Richard Barton 8d519fe015 Add AArch32 DCPS{1,2,3} and HLT instructions.
These were pretty straightforward instructions, with some assembly support
required for HLT.

The ARM assembler is keen to split the instruction mnemonic into a
(non-existent) 'H' instruction with the LT condition code. An exception for
HLT is needed.

HLT follows the same rules as BKPT when in IT blocks, so the special BKPT
hadling code has been adapted to handle HLT also.

Regression tests added including diagnostic tests for out of range immediates
and illegal condition codes, as well as negative tests for pre-ARMv8.

Tilmann Scheller 841a9ccfed Reverting 190043 for now.
Solution is not sufficient to prevent 'mov pc, lr' being emitted for jump table code.

Tilmann Scheller a1787a5835 ARM: Add GPR register class excluding LR for use with the ADR instruction.
This improves code generation for jump tables by avoiding the emission of "mov pc, lr" which could fool the processor into believing this is a return from a function causing mispredicts. The code generation logic for jump tables uses ADR to materialize the address of the jump target.

Venkatraman Govindaraju 55ecb10e99 [Sparc] Correctly handle call to functions with ReturnsTwice attribute.
In sparc, setjmp stores only the registers %fp, %sp, %i7 and %o7. longjmp restores
the stack, and the callee-saved registers (all local/in registers: %i0-%i7, %l0-%l7)
using the stored %fp and register windows. However, this does not guarantee that the longjmp
will restore the registers, as they were when the setjmp was called. This is because these
registers may be clobbered after returning from setjmp, but before calling longjmp.

This patch prevents the registers %i0-%i5, %l0-l7 to live across the setjmp call using the register mask.

Jim Grosbach 13654dd303 ARM: Teach A15 SDOptimizer to properly handle D-reg by-lane.
These instructions, such as vmul.f32, require the second source operand to
be in D0-D15 rather than the full D0-D31. When optimizing, make sure to
account for that by constraining the register class of a replacement virtual
register to be compatible with the virtual register(s) it's replacing.

I've been unsuccessful in creating a non-fragile regression test. This issue
was detected by the LLVM nightly test suite running on an A15 (Bullet).

Rafael Espindola 128c5ea902 Revert "Add r159136 back now that pr13124 has been fixed."
This reverts commit r189886.

I found a corner case where this optimization is not valid:

Say we have a "linkonce_odr unnamed_addr" in two translation units:
* In TU 1 this optimization kicks in and makes it hidden.
* In TU 2 it gets const merged with a constant that is *not* unnamed_addr,
  resulting in a non unnamed_addr constant with default visibility.
* The static linker rules for combining visibility them produce a hidden
  symbol, which is incorrect from the point of view of the non unnamed_addr
  constant.

The one place we can do this is when we know that the symbol is not used from
another TU in the same shared object, i.e., during LTO. I will move it there.

Alexander Kornienko 9aa60fd6f8 Move generic isPrint and columnWidth implementations to a separate header/source to allow using both generic and system-dependent versions on win32.
Summary:
This is needed so we can use generic columnWidthUTF8 in clang-format on
win32 simultaneously with a separate system-dependent implementations of
isPrint/columnWidth in TextDiagnostic.cpp to avoid attempts to print Unicode
characters using narrow-character interfaces (which is not supported on Windows,
and we'll have to figure out how to handle this).

llvm-svn: 189870
2013-09-03 22:40:56 +00:00
Michael Gottesman e29b1c1825 [objc-arc] Turn off the objc_retainBlock -> objc_retain optimization.
The reason that I am turning off this optimization is that there is an
additional case where a block can escape that has come up. Specifically, this
occurs when a block is used in a scope outside of its current scope.

This can cause a captured retainable object pointer whose life is preserved by
the objc_retainBlock to be deallocated before the block is invoked.

An example of the code needed to trigger the bug is:

----
\#import <Foundation/Foundation.h>
int main(int argc, const char * argv[]) {
  void (^somethingToDoLater)();

  {
    NSObject *obj = [NSObject new];

    somethingToDoLater = ^{
      [obj self]; // Crashes here
    };
  }

  NSLog(@"test.");

  somethingToDoLater();

Daniel Sanders d9be5b2fdc [mips][msa] Added IntrNoMem and removed Commutative from sub intrinsics.
This changes the SelectionDAG nodes from ISD::INTRINSIC_W_CHAIN to
ISD::INTRINSIC_WO_CHAIN which enables easy lowering to equivalent SelectionDAG
nodes (e.g. __builtin_msa_sub_w -> ISD::SUB) in future patches since nodes
such as ISD::SUB do not have a chain.
It also corrects an obvious mistake, namely that the subtract intrinsics were
marked as being commutative.

As per a similar change in r189106
(http://llvm.org/viewvc/llvm-project?rev=189106&view=rev) there isn’t a new
testcase in this patch since the existing tests should test the intrinsics to
the same standard and the best I can do for a testcase would be a fragile
pass/maybe test of whether memory operations can (and do) cross the intrinsic.

Chandler Carruth 14aae04029 Fix some rather confusing indentation and control flow in the errno
printing routine. This is made harder to see due to the surprising

test the same thing.

The only "consequence" of this bug is re-assigning 'str' to an empty
string when computing the error string for an error number of 0 in the
event of a non-GNU strerror_r routine. So, nothing to see here other
than cleanup. It did help me find PR17055 in clang-format though.

Chandler Carruth baf3fdb86b Nuke the hilariously out of date suggestion to unpack llvm-gcc 4.2 as
part of getting started with LLVM.

The LLVM getting started document is in woeful need of attention. I may
get to some of this, but some random notes for folks interested:

1) We need to separate the getting started steps for folks who are
   interested in the core LLVM libs and nothing else, folks interested
   in a nifty C++ toolchain and nothing else, and folks interested in
   both.
2) We should include documentation for both release archives, svn, and
   git in equal portion, and we should document all of the various
   repositories of interest: llvm, clang, clang-tools-extra,
   compiler-rt, lld, libcxx, test-suite.
3) We should document the CMake build. We should probably document the
   CMake build first, and give a fall-back set of docs for the Makefile
   build for the use cases where that is still the preferred solution.
   This would more closely match the use cases that folks in the open
   source community are likely to have, and would remove a point of
   discrepancy between Linux, Windows, and Mac instructions.
4) Probably a ton of other modernization stuff that I've not thought of
   here.

Anyways, if anyone at all is interested, please help clean up this
document. It is much needed.

Bill Schmidt eb8d6f7da0 [PowerPC] Fast-isel cleanup patch.
Here are a few miscellaneous things to tidy up the PPC64 fast-isel
implementation.  I corrected a couple of commentary lapses, and added
documentation of future opportunities.  I also implemented
TargetMaterializeAlloca, which I somehow forgot when I split up the
original huge patch.

Finally, I decided to delete SelectCmp.  I hadn't previously hooked it
in to TargetSelectInstruction(), and when I did I realized it wasn't
serving any useful purpose.  This is only useful for compares that
don't feed a branch in the same block, and to handle that we would
have to have logic to interpret i1 as a condition register.  This
could probably be done, but would require Unseemly Hackery, and
honestly does not seem worth the hassle.

This ends the current patch series.

cases.

Daniel Dunbar eb6c708d92 [conf] Add config variable to disable crash related overrides.
- We do some nasty things w.r.t. installing or overriding signal handlers in
   order to improve our crash recovery support or interaction with crash
   reporting software, and those things are not necessarily appropriate when
   LLVM is being linked into a client application that has its own ideas about
   how to do things. This gives those clients a way to disable that handling at
   build time.

 - Currently, the code this guards is all Apple specific, but other platforms
   might have the same concerns so I went for a more generic configure
   name. Someone who is more familiar with library embedding on Windows can
   handle choosing which of the Windows/Signals.inc behaviors might make sense
   to go under this flag.

 - This also fixes the proper autoconf'ing of ENABLE_BACKTRACES. The code
   expects it to be undefined when disabled, but the autoconf check was just
   defining it to 0.

Reed Kotler c03807a3a5 Fix a problem with dual mips16/mips32 mode. When the underlying processor
has hard float, when you compile the mips32 code you have to make sure
that it knows to compile any mips32 routines as hard float. I need to clean
up the way mips16 hard float is specified but I need to first think through
all the details. Mips16 always has a form of soft float, the difference being
whether the underlying hardware has floating point. So it's not really
necessary to pass the -soft-float to llvm since soft-float is always true
for mips16 by virtue of the fact that it will not register floating point
registers. By using this fact, I can simplify the way this is all handled.

Bill Schmidt ccecf26157 [PowerPC] Add loads, stores, and related things to fast-isel.
This is the next big chunk of fast-isel code.  The primary purpose is
to implement selection of loads and stores, but there is a lot of
drag-along to support this.  The common code to analyze addresses for
both loads and stores is substantial.  It's also necessary to add the
materialization code for global values.

Related to load-store processing is the code to fold loads into
integer extends, since otherwise we generate lots of redundant
instructions.  We also need to add some overrides to some FastEmit
routines to ensure we don't assign GPR 0 to a virtual register when
this would change the meaning of an instruction.

I added handling selection of a few binary arithmetic instructions, to
enable committing some test cases I wrote a while back.

Finally, ap couple of miscellaneous changes:
 * I cleaned up some poor style from a previous patch in
   PPCISelLowering.cpp, pointed out by David Blaikie.
 * I enlarged the Addr.Offset field to avoid sign problems with 32-bit
   offsets.

Eli Friedman e72f132097 Change default # of digits for APFloat::toString
This is a re-commit of r189442; I'll follow up with clang changes.

The previous default was almost, but not quite enough digits to
represent a floating-point value in a manner which preserves the
representation when it's read back in.  The larger default is much
less confusing.

I spent some time looking into printing exactly the right number of
digits if a precision isn't specified, but it's kind of complicated,
and I'm not really sure I understand what APFloat::toString is supposed
to output for FormatPrecision != 0 (or maybe the current API specification
is just silly, not sure which).  I have a WIP patch if anyone is interested.

Manman Ren 0b41040782 DIBuilder: retain a type when created with a unique identifier.
createClassType, createStructType, createUnionType, createEnumerationType,
and createForwardDecl will retain a type when created with a unique identifier,
to make sure they are treated as used even when all uses are replaced with
the identifiers.

Use TrackingVH<MDNode> instead of MDNode in AllRetainTypes, since the created
node can later be updated.

The change will be tested when clients of DIBuilder start to pass in non-empty

Add getUnrollingPreferences to TTI

Allow targets to customize the default behavior of the generic loop unrolling
transformation. This will be used by the PowerPC backend when targeting the A2

Hal Finkel 6d09904cc9 Disable unrolling in the loop vectorizer when disabled in the pass manager
When unrolling is disabled in the pass manager, the loop vectorizer should also
not unroll loops. This will allow the -fno-unroll-loops option in Clang to
behave as expected (even for vectorizable loops). The loop vectorizer's
-force-vector-unroll option will (continue to) override the pass-manager
setting (including -force-vector-unroll=0 to force use of the internal
auto-selection logic).

In order to test this, I added a flag to opt (-disable-loop-unrolling) to force
disable unrolling through opt (the analog of -fno-unroll-loops in Clang). Also,
this fixes a small bug in opt where the loop vectorizer was enabled only after
the pass manager populated the queue of passes (the global_alias.ll test needed
a slight update to the RUN line as a result of this fix).

Kevin Enderby 3aeada287b The integrated darwin assembler can hang in an infinite loop (or get an assert
with a debug build) with this buggy .indirect_symbol directive usage:

% cat test.s
x: .indirect_symbol _y

The assertion is because it is trying to get the symbol index for the
symbol _y when it is writing out the indirect symbol table. This line of
code in MachObjectWriter::WriteObject() :

        Write32(Asm.getSymbolData(*it->Symbol).getIndex());

And while there is a symbol _y it does not have any getSymbolData set which
is only done in MachObjectWriter::BindIndirectSymbols() for pointer sections
or stub sections.  I added a check and an error in there to catch this in case
something slips through.

But to get a better error the parser should detect when a .indirect_symbol
directive is used and it is not in a pointer section or stub section.  To make
that work I moved the handling of the indirect symbol out of the target
independent AsmParser code into the DarwinAsmParser code that can check
for the proper Mach-O section types.

These intrinsics are legalized to V(ALL|ANY)_(NON)?ZERO nodes,

a branch/mov sequence to evaluate to 0 or 1.

Note: The resulting code is sub-optimal since it doesnt seem to be possible
to feed the result of an intrinsic directly into a brcond. At the moment
it uses (SETCC (VALL_ZERO $ws), 0, SETEQ) and similar which unnecessarily
evaluates the boolean twice.

Eli Friedman 14cede2829 Change default # of digits for APFloat::toString
The previous default was almost, but not quite enough digits to
represent a floating-point value in a manner which preserves the
representation when it's read back in.  The larger default is much
less confusing.

I spent some time looking into printing exactly the right number of
digits if a precision isn't specified, but it's kind of complicated,
and I'm not really sure I understand what APFloat::toString is supposed
to output for FormatPrecision != 0 (or maybe the current API specification
is just silly, not sure which).  I have a WIP patch if anyone is interested.

Hans Wennborg d2cbe22b4a cmake: Add msbuild integration to the install
This adds the msbuild integration files to the install, provides batch scripts
for (un)installing it in a convenient way, and hooks up the nsis installer to
run those scripts.

Argyrios Kyrtzidis aae63a0ce6 [BumpPtrAllocator] Move DefaultSlabAllocator to a member of BumpPtrAllocator, instead of a static variable.
The problem with having DefaultSlabAllocator being a global static is that it is undefined if BumpPtrAllocator
will be usable during global initialization because it is not guaranteed that DefaultSlabAllocator will be
initialized before BumpPtrAllocator is created and used.

Eric Christopher d033d6fb88 Add support for DW_FORM_dataN and DW_FORM_udata to the DIE hashing
algorithm. Update the split dwarf hashing testcase accordingly - this
should be the last time that the hash of an empty file changes.

Eric Christopher 9d1daa87e7 Use DW_FORM_sdata for signed constant values and udata on occasion
when we can. Migrate from using blocks when we're adding just a
single attribute and floating point values are an unsigned, not signed,
bag of bits.

Update all test cases accordingly.
