The integration tests use both libcretonne and libreader, so moving them avoids
the circular dev-dependency.
Also go back to building everything under src/tools/target to avoid rebuilding
the libraries when cargo is invoked in different subdirectories. This speeds up
test-all.sh quite a bit.
Finally, skip the pure debug build. We build "cargo test" and "cargo build
--release" which should cover everything we need.
Replace the three tables instructions, extended_basic_blocks, and
extended_values with a single 'dfg' public member.
Clients using Function are changed to refer to func.layout and func.dfg
respectively.
The Layout also handles EBB layout, so new append_ebb calls are necessary.
- Rewrite callers to use the public data member 'layout'.
- Implement Debug for Function in terms of the write module to avoid deriving
it.
The 'cton-util cat' command parses the given files and writes them out again to
stdout. This has the effect of reformatting and stripping comments.
Fix a writer bug that inverted the blank line before the first EBB.
Add an external dependency to the docopt package and use it for a scaffold
command line interface for the cton-util command.
I am not too happy about taking external dependencies, and docopt pulls in 13
other packages. However, I really don't want to be writing command line parsers,
and as long as the external dependencies are confined to the tools crate, we
should be fine.
The core cretonne crate should stay free of external dependencies to avoid
trouble with embedding it.
Implement a basic 'cat' subcommand which currently behaves like unix 'cat'. It
will gain parser powers soon.
libctonfile -> libreader.
This library will only provide .cton file reading/parsing services which are
not needed after deployment.
Code for writing .cton files lives in the main cretonne library because it is
fairly small, and because it is useful for extracting test cases from a
deployed library.
The src/tools directory contains the cretonne-tools crate which will build
binaries for testing cretonne.
The src/libctonfile directory contains the ctonfile library crate which
provides reading and writing of .cton files.
