Git commit fffdf5d6536e4064bf089642f80d44192114edc5 by GitHub (on behalf of YongKang Zhu) on 09/08/2026 at 05:27..
[BOLT] Flip the first and last bits of build ID (#214784)

With only the last bit in a build ID flipped, some crash analysis or
symbolication tools that derive module ID from the first 16 bytes are
not able to differentiate pre- and post-BOLT libraries if both are
archived. So besides the last bit, we now also flip the high bit of
the first byte in a build ID.

Git commit 05142fc7308d336d316c2d705ee205393f7576ea by GitHub (on behalf of Keshav Vinayak Jha) on 09/08/2026 at 06:38..
[flang] Reject module-scope fir.alloca (#214157)

`fir.alloca` represents a stack allocation, but its verifier currently
accepts operations placed directly in a `builtin.module`. During
FIR-to-LLVM conversion, `AllocaOpConversion::matchAndRewrite` calls
`getBlockForAllocaInsert`, which performs a `dyn_cast` to
`OutlineableOpenMPOpInterface` on the alloca's parent op.

For a module-level alloca the expected parent function/block does not
exist and the cast/assert fails.

This patch rejectsdirect module-scope `fir.alloca` operations during FIR
verification.

[CIR][AMDGPU] Add support for AMDGCN permlane builtins (#197526)

Adds codegen for the following AMDGCN permlane builtins:

- __builtin_amdgcn_permlane16
- __builtin_amdgcn_permlane64
- __builtin_amdgcn_permlanex16

These are lowered to the corresponding `llvm.amdgcn.permlane16`,
`llvm.amdgcn.permlanex16`, and `llvm.amdgcn.permlane64` intrinsics.

[DomTree] Remove the DomTreeNodeBase overload of isReachableFromEntry. NFC (#215068)

The overload is `return A;`, which is not useful.

[SPARC] Fix %hi/%lo of absolute expressions in PIC mode (#215066)

adjustPICRelocation maps %hi/%lo to GOT22/PC22 or GOT10/PC10 at parse
time, before the operand is known to be absolute. adjustFixupValue has
no case for the GOT types, so an absolute operand encodes the unshifted
value:

Encode %got22/%got10 like %hi/%lo. Also drop them as input syntax; GNU
as has no such operators.

[VPlan] Add tests for outer-loop accesses with irregular types (NFC). (#215075)

Add coverage for stride-1 outer-loop accesses of element types that are
bit-packed in vectors (i1, i4).

While touching the file, remove some unnecessary checks.

[ORC] Rename RTBridge Caller to Proxy (#215077)

Mechanical rename of the controller-side call handle, with no functional
change:

- rt::Caller<Sig> -> rt::Proxy<Sig> (and CallerBase / CallerInit /
callerInit / buildCallers -> Proxy*), RTBridge/Calls.h ->
RTBridge/Proxy.h.
- rt::sps::CallerSpec -> rt::sps::ProxySpec, RTBridge/SPS/Calls.h ->
RTBridge/SPS/ProxySpecs.h.
- The named proxies for function-calling wrappers gain a Call verb
(CallMainProxy, CallInt32Int32Proxy, ...), matching the
orc_rt_ci_sps_call_* wrappers they target.

This frees "caller" for the executor-side concept: a runtime function
that calls another function.

Also split the unit test along the same seam: ProxyTest.cpp covers
generic, protocol-agnostic rt::Proxy behavior via an in-process dispatch
(no serialization), and SPSProxiesTest.cpp covers the SPS proxies'
serialization round-trips.
