Detailed Description

F4MemoryBlock<T, NSLAB> — F4's templated slab bump allocator.

Note

AI-generated documentation. Verify against the source before relying on it.

Declares F4MemoryBlock, the F4-internal slab allocator parameterised on the value type T and the slab capacity NSLAB (default 4092 chosen so each slab lands near 16 KB for the typical T and stays L1-resident). The allocator keeps a linked list of slab records; allocate(len) returns the next len Ts from the current slab in one call (or you can split it into reserve(len) to obtain a pointer and intern(len) to commit the bump), allocating and chaining a new slab on overflow. reset() rewinds the cursor to the first slab without freeing the chain — so a generation of transient F4 monomials, S-pair indices, or coefficient arrays can be allocated and then bulk-discarded with no per-allocation cost.

Counterpart to the top-of-engine MemoryBlock (a memtailor::Arena wrapper); the in-F4 version exists so the F4 inner loop can stay independent of the submodule and specialise the slab layout to the value type at compile time.
