NAS-140383 / 27.0.0-BETA.1 / Fix cloud sync with S3 provider behind a proxy (#18543)
Rclone v1.73 (using AWS SDK v2) signs the Accept-Encoding: identity
header as part of the SigV4 signature. Some reverse proxies modify that
header before it reaches the S3 gateway, so the server computes a
different signature and rejects the request. Setting
sign_accept_encoding = false excludes that header from the signature,
matching what the old rclone v1.67 did.
[DA] Bug fix regarding the SameSD levels (#188098)
SCEV isKnownPredicate may crash if the expressions are involved with
different loops. To verify if two loops have the same iteration space,
we do not need to use the SCEV apis, and it can be done by the equality
check.
Moreover, no pass (not even loop fusion) requires to check SameSD levels
for more than one level. In this patch, we limit the analysis of SameSD
levels to only one level after the common levels.
hwpmc.4: correct stale default values and update diagnostics
The default values documented for kern.hwpmc.logbuffersize (4KB) and
kern.hwpmc.nbuffers_pcpu (64) have been incorrect since 2981a3420cb1
(2018), which updated the compiled defaults but did not update the
man page.
- Correct logbuffersize default from 4KB to 256KB, add 16MB maximum
- Correct nbuffers_pcpu default from 64 to 32, document 32MB per-CPU
product limit with kern.hwpmc.logbuffersize
- Update DIAGNOSTICS section to reflect current warning messages

hwpmc: improve diagnostic messages for invalid tunables
Replace printf() with log(LOG_WARNING, ...) in pmclog_initialize()
so that tunable validation failures are visible in dmesg and
/var/log/messages rather than only on the early console.
Also improve the messages to report both the invalid value and the
default it resets to, making it easier for users to understand why
their tunable was ignored.
While here, adjust some whitespacing/style.

libpmc: Add support for IBS qualifiers
Add support to libpmc for parsing the IBS qualifiers and computing the
ctl register value as a function of the qualifiers and the sample rate.
This includes all of the flags available up to AMD Zen 5. Along side
these user facing changes I included the documentation for AMD IBS.

hwpmc: Use rdtsc instead of rdtscp for timestamps
No need for a barrier here, we are inside an NMI handler and executing a
number of serializing instructions with stronger semantics. Reducing
this overhead will increase our maximum safe sampling rate.

net/ntp: Reverse check for libmd and libmd5
When www/libwww is installed, it provides an incompatible libmd5
resulting ntp using libmd5 instead of libmd, breaking the build.
Reversing the order in which libmd and libmd5 are checked circumvents
this problem.

[LoopFusion] Remove the InvalidDependencies duplicates (#187744)
If the function dependencesAllowFusion returns false, in fuseCandidates
the reportLoopFusion function is used to increment InvalidDependencies

appear duplicated

Update dependencies.
Changes since 2.10.2:
- Fixed a retry bug in upload_unbound_stream() small-file uploads
where a retryable upload error could cause a one-shot buffered
stream to be reopened after it was closed.
- Address backwards compatibility issue for sqlite account info
caused by the migration of schema to a new multi-bucket format.
- Avoid http-level retries during upload requests.
- Use stat.S_ISDIR check for local folder children scanning instead
of Path.is_dir to account for an api change in Python 3.14.

[AMDGPU][DAGCombiner][GlobalISel] Extend allMulUsesCanBeContracted with FMA/FMAD pattern
Add conservative FMA/FMAD recognition to allMulUsesCanBeContracted:
a multiply used by an existing FMA/FMAD is assumed to be contractable
(it's already being contracted elsewhere). This avoids unnecessary
contraction blocking for multiplies that feed into FMA chains.
Also adds FMA/FMAD to the FPEXT user set (fpext(fmul) --> fma is
recognized as contractable when isFPExtFoldable).
Guards all remaining FMA-chain reassociation fold sites in both
SDAG (visitFADDForFMACombine/visitFSUBForFMACombine, 8 sites) and
GISel (matchCombineFAddFpExtFMulToFMadOrFMAAggressive, 4 sites).
This re-enables contractions that were conservatively blocked in
earlier patches where the multiply had an FMA use that wasn't yet
recognized: dagcombine-fma-crash.ll and dagcombine-fma-fmad.ll
CHECK lines revert to upstream behavior.

[lldb] Check for arm64e debugserver in skipUnlessArm64eSupported (#188082)
Explicitly check whether we are building debugserver for arm64e. To
debug an arm64e binary, debugserver itself needs to be an arm64e
process.
This PR eliminates the possibility of configuring LLDB with Right now,
it's possible to configure CMake with
`LLDB_ENABLE_ARM64E_DEBUGSERVER=Off` and the decorator wouldn't account
for that.
[AMDGPU][DAGCombiner][GlobalISel] Extend allMulUsesCanBeContracted with FPEXT pattern
Extend the allMulUsesCanBeContracted analysis to recognize FPEXT patterns
where the multiply result flows through fpext before being used in
contractable operations (fadd, fsub). This covers:
- fmul --> fpext --> {fadd, fsub}: FPEXT folds if isFPExtFoldable
- fmul --> fpext --> fneg --> fsub: FPEXT then FNEG to FSUB
- fmul --> fneg --> fpext --> fsub: FNEG then FPEXT folds if foldable
Also adds allMulUsesCanBeContracted guards to all FPEXT fold sites in
both SDAG (visitFADDForFMACombine, visitFSUBForFMACombine) and GISel
(matchCombineFAddFpExtFMulToFMadOrFMA, matchCombineFSubFpExtFMulToFMadOrFMA,
matchCombineFSubFpExtFNegFMulToFMadOrFMA).
Fixes a missing isFPExtFoldable check in GISel's
matchCombineFSubFpExtFMulToFMadOrFMA which could fold without verifying
the extension is actually foldable.

[HLSL] Implement Texture2D::mips[][]
We implement the Textur2D::mips[][] method. We follow the design in DXC.
There is a new member called `mips` with type mips_type. The member will
contain a copy of the handle for the texture.
The type `mips_type` will have a member function `operator[]` that takes
a level, and returns a `mips_slice_type`. The slice will contain the
handle and the level. It also has an operator[] member function that
take a coordinate. It will do a load from the handle with the level and
coordinate, and return that value.
