Specify the location of arguments as well as the size of stack argument
array needed. The ABI annotations are optional, just like the value
locations.
Remove the Eq implementation for Signature which was only used by a
single parser test.
- Remove NO_VALUE and ExpandedValue::None.
- Remove the Default implelmentation for Value.
- InstructionData::second_result() returns an Option<Value>.
- InstructionData::second_result() returns a reference to the packed
option.
This was only used for the comment rewrite mechanism, and we can just
predict the next allocated instruction number instead. See the other
uses of next_key() for gather_comments().
Use this source map method for assigning a location to any entity whose
source number is not exposed. This could be
- Instructions.
- Signatures defined implicitly by function decls.
These entities only appear in the location map, not the entity number
maps.
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'.
