[CIR]Implement lowering for simple sin/cos/tan/exp10 builtins. (#211614)

Discovered these just looking around, they are pretty simple/trivial
translations to LLVM-IR intrins, and the infrastructure to do so is
already in place, so this is a bit of simple wiring up!

Implements f/h/hl versions of sin/cos/tan. Also implements base-10
exponent, since it is also trivial.

Git commit 3ce0df7ca8027229618de9802eeffe1f0023bf74 by GitHub (on behalf of Volodymyr Sapsai) on 30/07/2026 at 17:15..
[Modules] Handle decl attributes on deserialization the same as during parsing. (#208348)

Replace manual handling of 2 attributes with
`Sema::mergeDeclAttributes`, which is called during parsing too. Also
propagate attributes not from a previous redeclaration but from a
previous redeclaration outside of the current module. This is done to
avoid double propagation because attributes from a previous decl in the
same module are already handled when a module is built.

Call `ASTDeclReader::attachLatestDecl` after each decl is added to a
redeclaration chain, not once per `ASTReader::loadPendingDeclChain`
call. This is done to maintain correct redeclaration chain for each
`ASTDeclReader::attachPreviousDecl` call because [newly added]
`mergeDeclAttributes` requires a correct redeclaration chain.

Separated `Parser::Initialize` and `Parser::ConsumeToken` so can move
the initialization earlier, into `Parser` constructor. This way
`Parser::Initialize`, `Sema::Initialize`, `ASTReader::InitializeSema` are
executed before deserialization. This specific case is verified by
"Modules/decl-attr-merge-explicit-modules.c".

The change can cause compilation errors for downstream `Parser` clients.
Instead of calling `Parser::Initialize` now you need to call
`Parser::ConsumeToken`.

Git commit 97ff9fc6daee52427f64ba9f11c1c6f268fab4fa by GitHub (on behalf of Erich Keane) on 30/07/2026 at 17:15..
[CIR] Allow cir.copy to work across address spaces- (#211873)

LLVM Memcpy supports copying across address spaces, so we should too. IN
C, this is legal, and there are no associated AST nodes to reasonably
put in a cast, so this patch just legalizes it to match the LLVM
behavior.

Note: I've added a 'CopyTypes' printer/parser as well, because it seems
unfortunate to make EVERY copy have to show all of its types.

[SLP]Release scheduling deps of copyable reassoc operands only once

A flattened reassoc node may have a scalar that is both a modeled
copyable tree operand (child entry) and a direct IR operand of a node
member. Scheduling such a member released its ScheduleCopyableData
dependency twice - in the per-lane operand scan and again in the
reassoc operand cleanup - driving UnscheduledDeps negative. Dedup the
cleanup release through the same Checked set the operand scan uses.

IR: Use LongDoubleFormat enum for long-double-type module flag (#213056)

Add parse/print helpers for the LongDoubleFormat enum, and route the
"long-double-type" module flag producers and consumers through them
instead of hardcoded strings in every location. Also clean up some
unnecessary failure checks guaranteed by the verifier.
