3.8.0 August-8-2026
Add FFI_TYPE_VECTOR (SIMD) type support with libffi-computed
layout, for aarch64 and x86-64 (#1000, closes #773).
Add ffi_call_plan_size to report the total memory a reusable call
plan owns, for embedders that account for the memory held by
long-lived plans.
Add powerpc64 ELFv2 _Complex long double support for both
IBM-128 (double-double) and IEEE-128 formats (#1003, closes #1001).
Fix powerpc64 big-endian ELFv2 closures returning 5-, 6-, or
7-byte structs: missing return jump-table entries produced a
wrong result and leaked a libffi code pointer.
Fix ia64 return-value jump-table desync after the FFI_TYPE_LAST
bump, which corrupted small-struct and HFA returns.
Fix powerpc Darwin closure returns broken by #951 (#1002).
Return small (1, 2, 4 or 8 byte) structs in registers on the i386
FreeBSD and OpenBSD targets, matching the platform ABI and
fixing a segfault on struct returns through ffi_call and closures.
Cache the static trampoline "unsupported" result on hosts whose
page size exceeds the trampoline table mapping, avoiding
redundant re-initialization on every closure allocation
(e.g. 64K-page aarch64).
