* Put TargetIsa's emit_inst under a "testing_hooks" feature.
In practice, TargetIsa's emit_inst pulls in its own instantiation
of the target-specifi `emit_inst` functions, which can be quite
large, and LTO doesn't eliminate them because they're held live
by TargetIsa's vtable.
Fortunately, this function is only used by tests, so we can put
it behind a feature flag.
Fixes#530.
* Add comments for `emit_inst` to clarify its purpose.
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.
