1b30265c5c Define a "table" concept.
"Table" is to WebAssembly tables as "Heap" is to WebAssembly linear
memories.

6b88cd44a8 Update to rustfmt-preview (#348)
* Update to rustfmt-preview.

* Run "cargo fmt --all" with rustfmt 0.4.1.

rustfmt 0.4.1 is the latest release of rustfmt-preview available on the
stable channel.

* Fix a long line that rustfmt 0.4.1 can't handle.

* Remove unneeded commas left behind by rustfmt.

f636d795c5 load_complex and store_complex instructions (#309)
* Start adding the load_complex and store_complex instructions.

N.b.:
The text format is not correct yet. Requires changes to the lexer and parser.
I'm not sure why I needed to change the RuntimeError to Exception yet. Will fix.

* Get first few encodings of load_complex working. Still needs var args type checking.

* Clean up ModRM helper functions in binemit.

* Implement 32-bit displace for load_complex

* Use encoding helpers instead of doing them all by hand

* Initial implementation of store_complex

* Parse value list for load/store_complex with + as delimiter. Looks nice.

* Add sign/zero-extension and size variants for load_complex.

* Add size variants of store_complex.

* Add asm helper lines to load/store complex bin tests.

* Example of length-checking the instruction ValueList for an encoding. Extremely questionable implementation.

* Fix Python linting issues

* First draft of postopt pass to fold adds and loads into load_complex. Just simple loads for now.

* Optimization pass now works with all types of loads.

* Add store+add -> store_complex to postopt pass

* Put complex address optimization behind ISA flag.

* Add load/store complex for f32 and f64

* Fixes changes to lexer that broke NaN parsing.

Abstracts away the repeated checks for whether or not the characters
following a + or - are going to be parsed as a number or not.

* Fix formatting issues

* Fix register restrictions for complex addresses.

* Encoding tests for x86-32.

* Add documentation for newly added instructions, recipes, and cdsl changes.

* Fix python formatting again

* Apply value-list length predicates to all LoadComplex and StoreComplex instructions.

* Add predicate types to new encoding helpers for mypy.

* Import FieldPredicate to satisfy mypy.

* Add and fix some "asm" strings in the encoding tests.

* Line-up 'bin' comments in x86/binary64 test

* Test parsing of offset-less store_complex instruction.

* 'sNaN' not 'sNan'

* Bounds check the lookup for polymorphic typevar operand.

* Fix encodings for istore16_complex.

f4fe438bae Suppress a warning about AsciiExt being deprecated.
We currently support versions of Rust which need this import, so
suppress the warning on versions of Rust which deprecated it.

03ee007624 Use clippy (#276)
* cton-util: fix some clippy unnecessary pass-by-value warnings

* clippy: ignore too many arguments / cyclomatic complexity in module

since these functions are taking args coming from the command line, i
dont think this is actually a valid lint, morally the arguments are all
from one structure

* cton-util: take care of remaining clippy warnings

* cton-reader: fix all non-suspicious clippy warnings

* cton-reader: disable clippy at site of suspicious lint

* cton-frontend: disable clippy at the site of an invalid lint

* cton-frontend: fix clippy warnings, or ignore benign ones

* clippy: ignore the camelcase word WebAssembly in docs

* cton-wasm: fix clippy complaints or ignore benign ones

* cton-wasm tests: fix clippy complaints

* cretonne: starting point turns off all clippy warnings

* cretonne: clippy fixes, or lower allow() to source of problem

* cretonne: more clippy fixes

* cretonne: fix or disable needless_lifetimes lint

this linter is buggy when the declared lifetime is used for another type
constraint.

* cretonne: fix clippy complaint about Pass::NoPass

* rustfmt

* fix prev minor api changes clippy suggested

* add clippy to test-all

* cton-filetests: clippy fixes

* simplify clippy reporting in test-all

* cretonne: document clippy allows better

* cretonne: fix some more clippy lints

* cretonne: fix clippy lints (mostly doc comments)

* cretonne: allow all needless_lifetimes clippy warnings

remove overrides at the false positives

* rustfmt

15461c1e4b Add two new value types: iflags and fflags.
These two value types represent the state of CPU flags after an integer
comparison and a floating point comparison respectively.

Instructions using these types TBD.

b2a314a229 Add per-instruction source locations to the Cretonne IR.
Source locations are opaque 32-bit entities that can be used to
represent WebAssembly byte-code positions or some other source
identifier.

3b71a27632 Add heaps to the Cretonne IL.
Add preamble syntax for declaring static and dynamic heaps, and update
the langref section on heaps. Add IR support for heap references.

Remove the heap_load and heap_store as discussed in #144. We will use
heap_addr along with native load and store instructions in their place.

Add the heap_addr instruction and document its bounds checking
semantics.

bf4ae3bb2e Add global variables to Cretonne IL.
See #144 for discussion.

- Add a new GlobalVar entity type both in Python and Rust.
- Define a UnaryGlobalVar instruction format containing a GlobalVar
  reference.
- Add a globalvar.rs module defining the GlobalVarData with support for
  'vmctx' and 'deref' global variable kinds.

Langref:
    Add a section about global variables and the global_addr
    instruction.

Parser:
    Add support for the UnaryGlobalVar instruction format as well as
    global variable declarations in the preamble.

* Use debug_assert_eq instead of debug_assert with ==.

* Replace a &Vec argument with a &[...].

* Replace `a = a op b` with `a op= b`.

* Avoid unnecessary closures.

* Avoid .iter() and .iter_mut() for iterating over containers.

18b567f88e Flatten the Value reference representation.
All values are now references into the value table, so drop the
distinction between direct and table values. Direct values don't exist
any more.

Also remove the parser support for the 'vxNN' syntax. Only 'vNN' values
can be parsed now.

Lots of changes this time.

Worked around what looks like a rustfmt bug in parse_inst_operands where
a large match was nested inside Ok().

846db00a21 Move library crates under 'lib/'.
Give these crates each a more standard directory layout with sources in
a 'src' sub-sirectory and Cargo.toml in the top lib/foo directory.

Add license and description fields to each.

The build script for the cretonne crate now lives in
'lib/cretonne/build.rs' separating it from the normal library sources
under 'lib/cretonne/src'.
