b6fa40d6a3 Add a return_reg instruction to the base instruction set. 
Register-style return is used by all RISC architectures, so it is
natural to have a shared instruction representation.

0d77b19708 Use PackedOption<Value> instead of NO_VALUE. 
- 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.

1389a51c7a Avoid using NO_INST in the parser. 
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().

8d6d59cc7a Gather comments in the preamble of a test file. 
Comments preceding the first function are not associated with any
specific entity in the file. Put them in a TestFile::preamble_comments
field.

bdc95990d4 Add call and call_indirect instructions. 
Add a new IndirectCall instruction format which has a value callee as
well as the call arguments.

Define call and call_indirect instructions.

b8a76822cf Track signatures and function references in the source map. 2016-10-18 09:43:20 -07:00

80a6ae203d Generalize def_inst() to def_entity(). 
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.

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'.
