[QualGroup][docs] Clarify biannual membership review and active contributor status (#185884)
This patch updates the LLVM Qualification Group page to reflect the
outcome of the first biannual membership review (Feb 2026).
Changes include:
- clarifying that the members table reflects active contributors,
- removing non-active contributors from the active members list,
- distinguishing active contributors from observers / interested
participants,
- updating the membership review section to describe the biannual review
process.
This is a documentation/process update only.
LinuxKPI: add supporting #includes
Compiling drm-kmod on !X86 does not include asm/smp.h which includes
preempt.h on FreeBSD. In order to compile drm-kmod on other
architectures add the secondary #includes for preempt.h to
spinlock.h and hardirq.h (which now also gets included from highmem.h)
to connect the #include chain.

Depending on the base channel ni_vht_chan2 - ni_vht_chan1 can be
negative. Apply abs() as indicated in the comments right above
| CCFS1 - CCFS0 | = 8 or > 16

[CIR][ABI] Add _BitInt flag to IntType (#188113)
Add an optional `bitint` parameter to `cir::IntType` so CIR can
distinguish `_BitInt(N)` from builtin integer types like `__int128`.
Both lower to the same LLVM integer type, but they have different ABI
rules (alignment, passing convention) on x86_64.
The flag is set during CIRGen for `Type::BitInt`, printed/parsed as
`!cir.int<s, 128, bitint>`, and excluded from `isFundamental()`.
Existing 2-arg `IntType::get()` calls continue to work via a default
parameter.
[mlir][CSE] Delete dead code immediately in CSE pass (#190926)
This PR addresses an issue where dead code within a region prevents
essentially identical region ops from being CSE'd. Currently, CSE only
removes dead ops at the end of the pass. This PR fixes the issue by
deleting dead code immediately upon encounter.
[lldb] Upstream and adopt ReadUnsignedIntegersFromMemory in AppleObjCRuntimeV2 (#190564)
This PR upstreams ReadUnsignedIntegersFromMemory, which uses the
MultiMemRead packet to speed up reading unsigned numbers from memory.
Felipe landed this on Github because we didn't have a use-case for it
upstream, until now, which uses it to batch up reading ObjC runtime
symbols.
[SystemZ] Migrate BuiltinsSystemZ.def to TableGen (#190232)
Migrates BuiltinsSystemZ.def to BuiltinsSystemZ.td, and makes the
necessary code updates. It also introduce type `__uint128_t` to the
TableGen emitter, to have a type for the encoding `ULLLi`.
Migration was done with the help of a script generated by IBM Bob.
[InstCombine] Match a new form of truncating saturation (#189703)
This matches a pattern that clamps an integer value to the range for an
integer type with a smaller bitwidth, before truncating to that type.

lualoader: allow the local module to filter out the BE list
This allows something like the following local.lua to install a filter
to implement its own notion of hidden BEs using a naming convention of
a leading dot to hide them:
-- file: /boot/lua/local.lua
local core = require("core")
local function be_hide(be)
if core.isSingleUserBoot() then
-- All BEs are accepted for single-user
return true
end
local name = be:match("/([^/]+)$")
if not name then
-- Accept malformed BEs, for whatever reason
return true

[AMDGPU][ISel] Reduce `f64` compare to integer compare of upper half (#188356)
Truncate `f64` `setcc`s to upper 32-bit operands where possible.
These transformations are analogous to those in #181238, but for ordered
and unordered fp comparisons.
Fixes #187996.

[lldb] Bring Debuginfod's StreamedHTTPResponseHandler to SymbolLocatorSymStore (#187687)
SymbolLocatorSymStore used a simple local implementation of
HTTPResponseHandler so far. That was fine for basic usage, but it would
cause issues down the line. This patch hoists the
StreamedHTTPResponseHandler class from libDebuginfod to SupportHTTP and
integrates it in SymbolLocatorSymStore. PDB file downloads will now be
buffered on disk, which is necessary since they can be huge.
We use the opportunity an stop logging 404 responses (file not found on
server) and print warnings for all other erroneous HTTP responses. It
was more complicated before, because the old response handler created
the underlying file in any case. The new one does that only once the
first content package comes in.
