LLVM — llvm/trunk/lib/CodeGen/SelectionDAG LegalizeFloatTypes.cpp, llvm/trunk/test/CodeGen/AArch64 f16-instructions.ll

[CodeGen] Round [SU]INT_TO_FP result when promoting from f16.

If we don't, values that aren't precisely representable in f16 could
be used as-is in a promoted f32 operation, which would produce
incorrect results.

AArch64 had the correct behavior; add a focused test.

SDAG: Rename Select->SelectImpl and repurpose Select as returning void

This is a step towards removing the rampant undefined behaviour in
SelectionDAG, which is a part of llvm.org/PR26808.

We rename SelectionDAGISel::Select to SelectImpl and update targets to
match, and then change Select to return void and consolidate the
sketchy behaviour we're trying to get away from there.

Next, we'll update backends to implement `void Select(...)` instead of
SelectImpl and eventually drop the base Select implementation.

LLVM — lldb/trunk/include/lldb/Target LanguageRuntime.h, lldb/trunk/source/Core ValueObjectDynamicValue.cpp

Revert r268591

"Allow LanguageRuntimes to return an error if they fail in the course of dynamic type 

This is not meant to report that a value doesn't have a dynamic type - it is only meant as 
a mechanism to propagate actual type discovery issues (e.g. malformed type metadata for 
languages that have such a notion)

This information is used by ValueObjectDynamic to set its own m_error, which is a fairly 
sharp and heavyweight tool to begin with

For the time being, this is an architectural improvement but a practical no-op as no 
existing runtimes are actually setting errors"

I need to think about what I want to do in this space more carefully - this attempt might 
be too heavy of a hammer for the nail I am trying to fix, and I don't want to leave it in 
while I ponder

Degrade assertions to a warning in LTOCodeGenerator for preserved linkonce

The assertions were assuming that the linker will not ask to preserve

I degrade to a warning for now.

LLVM — llvm/trunk CMakeLists.txt, llvm/trunk/cmake/modules HandleLLVMOptions.cmake


As per the discussion on LLVM-dev this patch proposes removing LLVM_ENABLE_TIMESTAMPS.

The only complicated bit of this patch is the Windows support. On windows we used to log 
an error if /INCREMENTAL was passed to the linker when timestamps were disabled.

With this change since timestamps in code are always disabled we will always compile on 
windows with /Brepro unless /INCREMENTAL is specified, and we will log a warning when 
/INCREMENTAL is specified to notify the user that the build will be non-deterministic.

LLVM — llvm/trunk/lib/Target/ARM ARMConstantPoolValue.cpp, llvm/trunk/test/CodeGen/ARM litpool-licm.ll

ARM: don't attempt to merge litpools referencing different PC-anchors.

Given something like:

    ldr r0, .LCPI0_0 (== pc-rel var)
    add r0, pc

    ldr r1, .LCPI0_1 (== pc-rel var)
    add r1, pc

we cannot combine the 2 ldr instructions and litpools because they get added to
a different pc to form the correct address. I think the original logic came
from a time when we fused the LDRpci/PICADD instructions into one
pseudo-instruction so the PC was always immediately at-hand. That's no longer
the case.

Should fix general-dynamic TLS access on Linux, and quite possibly other -fPIC
code that relies on litpools (e.g. v6m and -Oz compilations) though trivial
tweaks of the .ll test didn't provoke anything.

LLVM — lldb/trunk/packages/Python/lldbsuite/test/python_api/event TestEvents.py

Fix TestEvents.py on OS X

This change addresses a hang/segfault in TestEvents.py. The threads that
run the listener loops now do an SBListener.Clear() before they wrap up
their work. This prevents the test from trying to clean up the
SBListener too late.

There is a separate issue here which is that we should prevent this
clean-up time lock-up, but that is out of scope for this particular
change. I'd like to get these tests back and running the normal flow
rather than skipping them.

This addresses:
llvm.org/pr25924 (at least, the OS X side, although I suspect this will
also address Linux)

LLVM — llvm/trunk/include/llvm/Object Error.h, llvm/trunk/lib/Object MachOObjectFile.cpp Error.cpp

Clean up the specific error message for a malformed Mach-O files with bad segment
load commands.

The existing test case in test/Object/macho-invalid.test for
macho-invalid-too-small-segment-load-command has a cmdsize of 55, while
being too small also it is not a multiple of 4.  So when that check is added
this test case will produce a different error. So I constructed a new test case
that will trigger the intended error.

I also changed the error message to be consistent with the other malformed Mach-O
file error messages which prints the load command index.  I also removed both
object_error::macho_load_segment_too_small and
object_error::macho_load_segment_too_many_sections from Object/Error.h
as they are not needed and can just use object_error::parse_failed and let the
error message string distinguish the specific error.
