WebAssembly defines how many pages of linear memory are owned by the
instance on startup. This limit can then be bumped via the grow_memory
operator.
Therefore, accesses outside the defined bounds are considered an
exception.
Add br_table2025-11-15T17:48:16+00:00Xavier Del Campo Romeroxavi92@disroot.org2025-11-15T17:48:16+00:00urn:sha1:0b2a1fd9439d5ab1cdc076d7b9f1e763c4900b74
br_table is in fact a generalization of other branch types like br or
br_if, since br_table contains several branches for the same pc inside
the nw_lo section.
Therefore, this kind of branch forced some changes to nwp_break and
those relying on it.
Add i32.shr_{s,u}2025-11-12T23:57:36+00:00Xavier Del Campo Romeroxavi92@disroot.org2025-11-12T23:57:36+00:00urn:sha1:ac1796a1281aa6a6c9da3e407cb871d321da9d6cexecute.c: Report exception also on repeated callback2025-11-11T23:33:40+00:00Xavier Del Campo Romeroxavi92@disroot.org2025-11-11T23:33:40+00:00urn:sha1:be7c97ce6ae43d677b28d455506fdaedf944a25b
So far, exceptions coming from the pc callback were only being reported
on its first call. However, pc callbacks might assign a continuation
callback if the operation cannot be completed on a single call.
Fix prev_op2025-11-11T23:32:15+00:00Xavier Del Campo Romeroxavi92@disroot.org2025-11-11T23:32:15+00:00urn:sha1:cf2882c2e754f49c46ce2ca12c3ca07e4cabc459
Assigning prev_op inside nwp_execute defeated the purpose because this
function is meant to start the state machine for the given instruction.
In other words, inspecting prev_op would in fact return the current
opcode, instead of the previous opcode.
