BE-614: HashQL: Generate synthetic closure bodies for intrinsics used as first-class values by indietyp · Pull Request #8895 · hashintel/hash

indietyp · 2026-06-22T16:43:22Z

🌟 What is the purpose of this PR?

Allows intrinsics to be used in value position (passed as arguments, bound to variables) by generating synthetic MIR wrapper bodies during reification. Previously, intrinsics like <= could only appear at call sites where specialization rewrites them. Now they can flow through higher-order functions:

let apply = fn (a, b, f) = (f a b) in
(apply 2 3 <=)

🔍 What does this change?

Synthetic body generation:

Synthetics struct in CrossCompileState manages creation and caching of wrapper bodies
SyntheticBuilder generates MIR bodies with fat closure ABI (unit env as first parameter)
T! macro for matching qualified paths against ConstantSymbol arrays: &T![::core::cmp::gt] in slice patterns, sym::path::core::cmp::gt::CONST for the name
Dispatch table covers all first-classable intrinsics (comparison, boolean, arithmetic, bitwise) with local binary!/unary! macros deriving path and name from the same segments

Thin-call specialization:

rvalue_call_thin_specialize recognizes Call(Thin, Qualified(intrinsic), []) (the administrative thunk-force from the thunking phase) and produces the closure aggregate directly, skipping thunk body generation
Type unwrapping handles the thunking phase's () -> ClosureType wrapper to extract the actual signature

Intrinsic classification:

First-classable: comparison (gt, lt, gte, lte, eq, ne), boolean (and, or, not), arithmetic (add, sub), bitwise (and, or, not)
Unconstructible MIR ops (BinOp variants with ! payload): mul, div, rem, mod, pow, xor, shl, shr
No MIR ops: sqrt, cbrt, root
Not first-classable (syntactic forms): graph::head::entities, graph::body::filter, graph::tail::collect produce a specific user-facing diagnostic

Diagnostics:

intrinsic_not_first_class: user-facing error for graph intrinsics in value position
synthetic_binary_arity_mismatch / synthetic_unary_arity_mismatch: ICE for monomorphized type invariant violations

Pre-Merge Checklist 🚀

🚢 Has this modified a publishable library?

This PR:

does not modify any publishable blocks or libraries, or modifications do not need publishing

📜 Does this require a change to the docs?

The changes in this PR:

are internal and do not require a docs change

🕸️ Does this require a change to the Turbo Graph?

The changes in this PR:

do not affect the execution graph

⚠️ Known issues

Bare intrinsic at module root ("<=" as the entire program) is not supported. The thunking phase does not wrap the root body when it is a variable, so it never reaches the synthetic machinery. Tracked with a run: skip test.

🐾 Next steps

Untyped property access (the original motivation for this work)
Module system support for root-level qualified paths (BE-67)

🛡 What tests cover this?

Compiletests (8 new):

reify/synthetic-intrinsic-value: basic synthetic body generation and thin-call specialization
reify/synthetic-intrinsic-reused: same intrinsic used twice shares one body (caching)
reify/synthetic-intrinsic-multiple: different intrinsics get separate bodies
reify/synthetic-graph-not-first-class: graph intrinsic in value position produces error
reify/synthetic-intrinsic-bare: bare intrinsic at root (run: skip)
interpret/synthetic-intrinsic-value: end-to-end correctness (evaluates to true)
post_inline/synthetic-intrinsic-hof: full optimization cascade with constants (collapses to return true)
post_inline/synthetic-intrinsic-hof-dynamic: HOF with dynamic inputs collapses to bare x <= y

❓ How to test this?

cargo run --package hashql-compiletest -- run --filter "test(synthetic)"

📹 Demo

The post_inline/synthetic-intrinsic-hof-dynamic test shows the full cascade. A higher-order function receiving <= as a value with dynamic inputs:

Initial:  construct closure for <=, pass to apply, call through fat pointer
Final:    %0 = input LOAD x
          %1 = input LOAD y
          %2 = %0 <= %1
          return %2

All indirection eliminated. Indistinguishable from writing ["<=", x, y] directly.

PR Summary

Medium Risk
Touches core MIR reification and closure ABI for many intrinsics; behavior is well-covered by compiletests but wrong arity/type unwrapping could affect optimization and interpretation paths.

Overview
Enables intrinsics in value position (e.g. passing <= into a higher-order function) by generating cached synthetic MIR bodies during reification, instead of treating qualified paths as unsupported external modules.

Reification now routes qualified variables through Synthetics::find_or_insert, which matches known ::core::… paths and emits fat-closure bodies (Source::Synthetic) for cmp/bool/math/bits ops; graph intrinsics get a dedicated not first-class error. rvalue_call_thin_specialize beta-reduces thunk-forced Call(Thin, Qualified, []) into a closure aggregate when possible.

Small supporting changes: From<ConstantSymbol> for Symbol, lhs/rhs symbols for synthetic locals, scratch.reset() after MIR reify in the graph compile path, and compiletests for reuse, multiple intrinsics, HOF + inlining, and failure cases.
