[NFCI][Globals] In GlobalObjects::setSectionPrefix, do conditional update if existing prefix is not equivalent to the new one. Returns whether prefix changed. (#158460)
Before this change, `setSectionPrefix` overwrites existing section
prefix with new one unconditionally.
After this change, `setSectionPrefix` checks for equivalences, updates
conditionally and returns whether an update happens.
Update the existing callers to make use of the return value. [PR
155337](https://github.com/llvm/llvm-project/pull/155337/files#diff-cc0c67ac89807f4453f0cfea9164944a4650cd6873a468a0f907e7158818eae9)
is a motivating use case whether the 'update' semantic is needed.
[OpenACC] verify acc:DataOp operand not BlockArgument (#159148)
Similar to #158095, check that the operand of acc::DataOp is not a
BlockArgument before trying to get its defining operation so it will not
segfault and instead produce a clean error.
[DA] Add option to run only SIV routines (#157084)
This patch introduces a new option, `da-run-siv-routines-only`, which
runs only the SIV family routines in the DA. This is useful for testing
(regression tests, not dependence tests) as it helps detect behavioral
changes in the SIV routines. Actually, regarding the test cases added in
#157085, fixing the incorrect result requires changes across multiple
functions (at a minimum, `exactSIVtest`, `gcdMIVtest` and
`symbolicRDIVtest`). It is difficult to address all of them at once.
This patch also generates the CHECK directives using the new option for
`ExactSIV.ll` as it is necessary for subsequent patches. However, I
believe it will also be useful for other `xxSIV.ll` tests. Notably, the
SIV family routines tend to be affected by other routines, as they are
typically invoked at the beginning of the overall analysis.
[offload] Fix build with debug libomptarget (#159144)
Currently get this error
```
offload/plugins-nextgen/common/src/PluginInterface.cpp:859:63: error: member reference type 'StringRef' is not a pointer; did you mean to use '.'?
```
We pass the full image binary now so we can't really print anything
useful here.
Seems introduced in https://github.com/llvm/llvm-project/pull/158748.

[CAS] Fix alignment error from MappedFileRegionArena (#159128)
Fix a bug that when an alignment error can happen when reading a slice
of file from existing MappedFileRegionArena.
[lldb-dap] Add stdio redirection (#158609)
As far as I understand, lldb-dap does not currently support stdio
redirection. I have added support for this via a new field in the launch
configuration named `stdio`. It was inspired by the same named field in
[CodeLLDB](https://github.com/vadimcn/codelldb/blob/master/MANUAL.md#stdio-redirection).
[mlir][tosa] Handle unsigned constants in `TosaConvertIntegerTypeToSignless` (#156483)
This commit fixes handling of unsigned constant data in the
`TosaConvertIntegerTypeToSignless` pass. Previously, the type of the
"values" attribute would remain unsigned, which caused an error in the
const ops verifier:
```
error: 'tosa.const' op expected same attr/result element types
%input_zp = "tosa.const"() {values = dense<17> : tensor<1xui8>} : () -> tensor<1xui8>
^
note: see current operation: %0 = "tosa.const"() <{values = dense<17> : tensor<1xui8>}> : () -> tensor<1xi8>
```
Now the constant data in "values" is transformed to signless as well.
[libc] Clean up mask helpers after allowing implicit conversions (#158681)
Summary:
I landed a change in clang that allows integral vectors to implicitly
convert to boolean ones. This means I can simplify the interface and
remove the need to cast to bool on every use. Also do some other
cleanups of the traits.
[clang][nfc] Fix tests to avoid writing output to unreachable location (#159138)
Note: this was originally done in (#158698) but was reverted in the
pr/158844 (which re-applied the original rev)
[CAS] Disable OnDiskCAS build on Solaris (#159122)
OnDiskCAS implementation receives error `No record locks available`
on Solaris. Disable building on Solaris for now to fix buildbot failure.
[SelectionDAGBuilder][PPC] Use getShiftAmountConstant. (#158400)
The PowerPC changes are caused by shifts created by different IR
operations being CSEd now. This allows consecutive loads to be turned
into vectors earlier. This has effects on the ordering of other combines
and legalizations. This leads to some improvements and some regressions.
[DTLTO][TEST] XFAIL Clang driver tests for Multicall toolchains (#159129)
Previously I masked issues with Multicall + DTLTO (see #148908) due to
an incomplete understanding of how the Multicall toolchain works.
This patch reverts those incorrect changes and instead marks the
affected tests XFAIL when running under Multicall.
Issue #159125 tracks fixing DTLTO with Multicall.
