WebAssembly doesn't have non-dense jump tables, and higher-level users
are better served by the facilities in lib/frontend/src/switch.rs for
working with non-dense switches.
This eliminates the concept of "absent" jump table entries, which
were represented as "0" in the text format.
Also, jump table contents are now enclosed in `[` and `]`, so that
we can unambiguously display empty jump tables. Previously, empty jump
tables were displayed as if they had a single absent entry.
* Add 'jump_table_entry' and 'indirect_jump' instructions.
* Update CodeSink to keep track of code size. Pretty up clif-util's disassembly output.
* Only disassemble the machine portion of output. Pretty print the read-only data after it.
* Update switch frontend code to use new br_table instruction w/ default.
* fix error not reported if at least one other error expected.
* Fixed unused extern crate error if wasm feature is not enabled.
* No longer reporting deref cycles multiple times.
* Fix filetest type_check.clif.
* Switched comparison order for perf.
* Fixed isa/riscv/verify-encoding.clif filetest.
* clippy: Allow subsec_nanos usage for now.
The recommendation from clippy requires Rust 1.27, but we currently
support Rust 1.25 and later.
* Simplify ref pattern matches.
This was recommended by clippy.
The individual crates are published separately from the main repository
on crates.io. To ensure that a copy of the LICENSE file accompanies all
published copies of the code, give each crate its own LICENSE file.
`urm_noflags` is a variant of `urm` which doesn't clobber the flags, and
`urm_noflags_abcd` is a further variant for ABCD registers, so it also
doesn't clobber the flags.
