Closes #26995. - - - - - eb14cbcb by Simon Jakobi at 2026-03-11T00:18:18-04:00 Add perf test for #1216 Closes #1216. - - - - - 481766ac by Sylvain Henry at 2026-03-11T00:18:39-04:00 JS: check that tuple constructors are linked (#23709) Test js-mk_tup was failing before because tuple constructors weren't linked in. It's no longer an issue after the linker fixes. - - - - - 0d2682d2 by Matthew Pickering at 2026-03-11T00:18:41-04:00 testsuite: Add test for foreign import prim with unboxed tuple return This commit just adds a test that foreign import prim works with unboxed sums. - - - - - d92a6559 by Matthew Pickering at 2026-03-11T00:18:41-04:00 Return a valid pointer in advanceStackFrameLocationzh When there is no next stack chunk, `advanceStackFrameLocationzh` used to return NULL in the pointer-typed StackSnapshot# result slot. Even though the caller treats that case as "no next frame", the result is still materialized in a GC-visible pointer slot. If a GC observes the raw NULL there, stack decoding can crash. Fix this by ensuring the dead pointer slot contains a valid closure pointer. Also make the optional result explicit by returning an unboxed sum instead of a tuple with a separate tag.
