+ ...
+ x.await_suspend(...);
+ ...
+ }
+ x.await_resume();
+ ```
+
+ `cir.await` represents this logic by using 3 regions:
+ - ready: covers veto power from x.await_ready()
+ - suspend: wraps actual x.await_suspend() logic
+ - resume: handles x.await_resume()
+
+ Breaking this up in regions allows individual scrutiny of conditions
+ which might lead to folding some of them out. Lowerings coming out
+ of CIR, e.g. LLVM, should use the `suspend` region to track more
+ lower level codegen (e.g. intrinsic emission for coro.save/coro.suspend).
+
+ There are also 4 flavors of `cir.await` available:
+ - `init`: compiler generated initial suspend via implicit `co_await`.
+ - `user`: also known as normal, representing a user written `co_await`.
+ - `yield`: user written `co_yield` expressions.
+ - `final`: compiler generated final suspend via implicit `co_await`.
+
+ ```mlir
+ cir.scope {
+ ... // auto &&x = CommonExpr();

Subject: [PATCH 6/6] [CIR][X86] Implement lowering for sqrt builtins
Implements CIR IR generation for X86 sqrt builtin functions, addressing issue #167765.
This change adds support for lowering the following X86 sqrt builtins to CIR operations:
- __builtin_ia32_sqrtps (128-bit float vector sqrt)
- __builtin_ia32_sqrtps256 (256-bit float vector sqrt)
- __builtin_ia32_sqrtps512 (512-bit float vector sqrt)
- __builtin_ia32_sqrtpd (128-bit double vector sqrt)
- __builtin_ia32_sqrtpd256 (256-bit double vector sqrt)
- __builtin_ia32_sqrtpd512 (512-bit double vector sqrt)
- __builtin_ia32_sqrtph, __builtin_ia32_sqrtph256, __builtin_ia32_sqrtph512 (half precision)
- __builtin_ia32_vsqrtbf16, __builtin_ia32_vsqrtbf16256, __builtin_ia32_vsqrtbf16512 (bfloat16)
- __builtin_ia32_sqrtsh_round_mask, __builtin_ia32_sqrtsd_round_mask, __builtin_ia32_sqrtss_round_mask (masked rounding)
Changes:
- Added CIROps.h wrapper header for CIR operation declarations
- Updated CIROps.td with SqrtOp definition (Pure trait, type-safe constraints)
- Updated CIRTypeConstraints.td with float type constraints
- Implemented builtin handling in CIRGenBuiltinX86.cpp
- Added comprehensive test coverage in cir-sqrtps-builtins.c
The implementation follows existing CIR patterns and generates proper cir.sqrt operations
for all sqrt builtin variants with appropriate type checking and lowering to LLVM IR.
