[SCEV] - Add positive-stride predicate for backedge-taken count. (#222261)
When `howManyLessThans` encounters a loop with an unknown stride that
cannot be proven finite (no `mustprogress` or side-effect-free
guarantee), SCEV currently returns `CouldNotCompute` for the
backedge-taken count. This blocks downstream consumers like the loop
vectorizer from optimizing such loops.
This patch relaxes the requirement by allowing a predicated
backedge-taken count when `AllowPredicates` is true. Instead of
requiring `loopIsFiniteByAssumption(L)` unconditionally, we add a
`Compare predicate: stride sgt 0` when finiteness cannot be proven.
A positive stride guarantees forward progress, making the BTC formula
correct. The predicate is emitted as a runtime check by consumers
(e.g., the loop vectorizer generates a guard branch before the vector
loop).

[docs] Pass -c when generating a PCH file (#226850)
Without options like -fsyntax-only/-E/-S/-c, the driver runs in link
mode, and a header-only command line produces a PCH only incidentally: a
linker option such as -lm or -Wl,..., including one from a config file,
adds a link job. Use -c in the PCH examples.
Also fix two broken examples: -ignore-pch is a driver option (cc1
rejects -Xclang -ignore-pch), and the relocatable PCH example is
missing -o. In LibASTImporter.md, generate the C++ AST files with
-emit-ast instead of treating .cpp files as headers.

net/samba424: fix swapped paths/targetdir args in join.py provision_fill call
patch-python_samba_provision_____init____.py extends provision_fill()'s
signature to provision_fill(..., paths, targetdir, schema=None, ...),
but the DCJoinContext call site in patch-python_samba_join.py passed
the two positional arguments in the opposite order (targetdir, paths).
This silently bound paths to a plain targetdir string and targetdir to
the ProvisionPaths object, which would raise AttributeError as soon as
provision_fill() accesses paths.netlogon/paths.sysvol.
Present identically since net/samba422 (join.py was not touched at all
in net/samba419) and carried forward unnoticed through samba423 and
samba424. Only reachable via the AD DC subdomain-join code path
(DCJoinContext), not via a fresh/root-domain provision.

[lldb][test] Handle None function name in frame provider tests (#226936)
Fixes #191859.
On Arm one of the functions has no name, which is a valid state.
```
Num frames: 7
0 frame #0: 0x092a151c a.out`baz at main.c:5:3 --name: baz
1 frame #1: 0x092a1540 a.out`bar at main.c:10:10 --name: bar
2 frame #2: 0x092a1560 a.out`foo at main.c:15:10 --name: foo
3 frame #3: 0x092a158c a.out`main at main.c:20:10 --name: main
4 frame #4: 0xf7ab939a libc.so.6` --name: None
5 frame #5: 0xf7ab943e libc.so.6`__libc_start_main + 94 --name: __libc_start_main
6 frame #6: 0x092a1434 a.out`_start + 40 --name: _start
```
The prefix provider needs to handle that possibility.
Though the Python type annotations on ScriptedFrame say that the name
methods return string, in reality they can return None, which the C++
sides expect. I will fix that in another PR.
[LLVMIR] Directly lower global initializer GEP to constant expression (#226904)
MLIR lowers global initializers in a very unusual way, by using an
IRBuilder without insertion point, and relying on the fact that for a
well-formed initializer, all the instructions will be converted to
constant expressions and no actual instructions that require insertion
will be produced.
This causes issues for https://github.com/llvm/llvm-project/pull/226425,
which requires an insertion point for CreateGEP to determine the data
layout.
To avoid this, make convertGEPOp() directly produce a constant
expression GEP if there is no insertion point, reusing the existing code
path for inrange GEPs.
[clang][bytecode] Use bytecode interpreter in toplevel `Expr::Evaluate*` functions (#226217)
To avoid all the state setup we otherwise do. This also lets us remove
the `EvalInfo::EnableNewConstInterp` flag, which was previously checked
on every `::EvaluateAsRValue` call.
[DirectX] Don't use IRBuilder to create GEPs (#227000)
This switches the DirectX backend to directly call
`GetElementPtrInst::Create()` instead of creating GEPs via IRBuilder.
IRBuilder will soon start canonicalizing GEPs to ptradd representation
(with the first change being
https://github.com/llvm/llvm-project/pull/226425, affecting constant
expressions only), while DirectX needs GEPs to have specific form.
The change implemented here is a minimal one to unblock further work. In
the future, it will become impossible to construct such GEPs through any
API. The DirectX backend needs to switch to using an intrinsic to
represent any non-canonical GEPs it needs. This followup work is tracked
in https://github.com/llvm/llvm-project/issues/227005.
system: add latency_avg as sanity check for running dpinger; closes #10937
The check was introduced in 0df1c0d so there's no technical background
to take into account. Indeed, latency_avg is probably the reading that
would least likely be 0 in this case.

[llvm][llvm-profgen] Fix printing bogus trace info on 32-bit (#226965)
And as a result, fix
llvm/test/tools/llvm-profgen/AArch64/cs-bogus-trace.test when run on Arm
32-bit:
https://lab.llvm.org/buildbot/#/builders/122/builds/59
Fixes #225569 / 28fec94991905d8dd8a08658e9590e13b7fe1af5.
`x` is for an unsigned integer but the argument given for it is a
uint64_t. This worked on 64-bit (maybe it's passed in a register), but
not on 32-bit where we got strange values printed.
Use format_hex instead, so we don't have to choose a format code.
[lldb] Correct types for ScriptedFrame get_function_name get_display_function_name (#226938)
These claimed to return str but the initial value for self.name is None,
and the C++ side returns optional<string>. So I think optional string is
correct here.
net/samba424: fix dropped %%GDB_CMD%% and %%SAMBA4_CONFIG%% placeholders
patch-buildtools_scripts_abi__gen.sh hardcoded the abi_gen.sh gdb
invocation to "true" instead of the %%GDB_CMD%% placeholder that the
port's post-patch target substitutes via _GDB_CMD. This made the
Makefile's REINPLACE_CMD for %%GDB_CMD%% a dead no-op and silently
disabled real gdb-based ABI/symbol-version checking under the
DEVELOPER option, even though the devel/gdb dependency is still pulled
in for that option.
patch-dynconfig_wscript hardcoded the CONFIGFILE path to smb4.conf
instead of the %%SAMBA4_CONFIG%% placeholder, making the corresponding
REINPLACE_CMD for %%SAMBA4_CONFIG%% a dead no-op too. Harmless in
practice since _SAMBA_CONFIG already equals smb4.conf, but it silently
removes the ability to reconfigure the config file name through the
mechanism the Makefile provides for it.
Restore both placeholders so the existing substitution logic in the
Makefile actually takes effect again.
