[AMDGPU] Fix buggy insertion of DEALLOC_VGPRS message (#178401)
We inserted the DEALLOC_VGPRS message if there were no pending scratch
stores the first time an S_ENDPGM instruction was visited. But because
this pass uses a worklist to revisit blocks until it reaches a fixed
point, it is possible that pending scratch stores are only discovered on
the second or later visit to a block. Fix this by storing a flag for
each S_ENDPGM instruction which can be updated by later visits.
[FileCheck] Allow -check-prefix to take multiple prefixes (#178187)
There was no real benefit to disallowing this, and it sometimes caused
unnecessary churn in the RUN lines of tests which were updated from
single-to-multiple or multiple-to-single prefixes.
This effectively makes -check-prefixes the primary option and
-check-prefix just an alias of it. The documentation is upated
accordingly.
[OpenMP][docs] Revise building manual (#176175)
Go into more detail on the two non-legacy build modes.
I decided use create a dedicated document documention the build process.
`index.rst` only keeps the "Getting Started" part. `README.rst` is
vastly outdated with the still valid parts integrated into the new
documentation. `SupportAndFAQ.rst` is unstructured and keeps only the
non-building parts.
The the new building document is written in Meltdown, following the
decision from LLVM.
[mlir][emitc] Fix recurring operands in expression (#178382)
Relanding #175535 which got reverted for failing the buildbot.
New canonicalization pattern moved to dialect code.
Remove python-pam and plumb in pam_truenas
This commit removes the python-pam Python library dependency from
TrueNAS middleware and replaces it with truenas_pypam. The most
significant change is the migration of API key authentication from
simple PBKDF2 password hashing to SCRAM-SHA512 (Salted Challenge
Response Authentication Mechanism) as defined in RFC5802. SCRAM is an
authentication protocol that uses PBKDF2-HMAC-SHA512 for key
derivation. API keys are now stored with SCRAM-derived credentials
including salt, stored_key, server_key, and iteration count fields in
the database. A database migration automatically converts existing
PBKDF2-hashed API keys to SCRAM format transparently—existing API keys
will continue to work without requiring regeneration. The commit adds a
new SCRAM authentication mechanism for challenge-response authentication
with replay resistance and mutual validation capabilities, while
maintaining the existing API_KEY_PLAIN mechanism for simple
authentication.
The refactoring includes comprehensive changes to the authentication
