Chris Lattner b20d96b89d Improve handling of keyword identifier parsing, allowing keywords like 
'reset' to be used in expressions.
 2020-04-01 17:14:19 -07:00
Chris Lattner b56febbc3f Implement skip, include a test that it persists its location correctly. 2020-04-01 16:56:27 -07:00
Chris Lattner 23578b05e3 implement partial connects, invalid's, and fix the implementation of connects. 
This also sets out a proper structure to handle expressions, but only trivial
ones are handled so far.
 2020-04-01 16:47:11 -07:00
Chris Lattner 43be6a333c minor grooming of the info location stuff, NFC. 2020-04-01 15:44:59 -07:00
Chris Lattner b1b7f92d73 Implement full support for Info locators and persisting them in MLIR locations. 2020-04-01 15:12:28 -07:00
Chris Lattner 0fd729f90a Tidy up location and spelling handling code, making it more orthogonal 
from the parser rules.  Add a testcase for location processing.
 2020-04-01 13:25:09 -07:00
Chris Lattner 6f017cc0bc Remove Connect's name, it isn't an expression or a declaration. 2020-04-01 13:05:50 -07:00
Chris Lattner 08372cba3e Update to ToT MLIR. 2020-04-01 11:50:06 -07:00
Chris Lattner ce7b0c7bbd Add parser and IR support for wire declarations. 
Fix some build errors that weren't showing up for me before, very weird.
Teach the parser about numeric field IDs.
 2020-04-01 11:44:20 -07:00
Chris Lattner 3ef45edf82 Implement support for looking up symbols and diagnosing use of invalid names. 
Start building IR for connects.
 2020-04-01 10:32:19 -07:00
Chris Lattner 4532248987 Add a symbol table for local declarations, starting with ports. 2020-03-31 23:10:22 -07:00
Chris Lattner a1d4320be3 More actively solicit a better name for this repo. 2020-03-31 21:04:58 -07:00
Chris Lattner dcc13ca49b Implement vector types. The type system is done! 2020-03-27 21:05:00 -07:00
Chris Lattner ef1811db70 Implement support for Bundle types. 2020-03-27 13:34:24 -07:00
Chris Lattner e97285aa6a Implement support for flip types, mapping output ports onto it. Stub out 
some parts of bundle and vector, but they are not implemented yet.
 2020-03-26 17:43:16 -07:00
Chris Lattner 6a87c32d1d rearrange the type system a bit, introduce a new common FIRRTLType class. 2020-03-26 11:25:16 -07:00
Chris Lattner d5af2ba90c Pull SInt/UInt width handling into the same architecture as Analog. 
This stops using the MLIR builtin type for ui/si types because it
makes them special and different - consistency seems more important
here within the firrtl dialect.
 2020-03-24 12:33:52 -07:00
Chris Lattner 6033f284f2 correctly parse the width in an int/analog spec. 2020-03-24 09:39:34 -07:00
Chris Lattner e30671ef0e Add support for widths on analog types. 2020-03-23 23:11:59 -07:00
Chris Lattner 48c4da1abf Start implementing the FIRRTL type system, "Ground types" first. 2020-03-23 11:57:27 -07:00
Chris Lattner dff5dd1691 Add ports to the MLIR representation. This plumbs through result 
returning into the portList parser and the type parser.
 2020-03-22 20:50:26 -07:00
Chris Lattner b11257833d create MLIR representation of circuit and module ops. This ignores 
ports, location info, etc.
 2020-03-22 12:31:23 -07:00
Chris Lattner 7668f6d04c Move the module parsing logic into a new FIRModuleParser class, NFC. 2020-03-22 11:43:44 -07:00
Chris Lattner 4b36d536dd Implement parser support for extmodule and info records. 2020-03-22 11:35:46 -07:00
Chris Lattner 4de1dbda33 Implement clases for the .fir parser mechanics, implementing just 
enough parser logic for circuit and modules to get through the
testcases.

In addition to the parser logic, this improves the lexer to be able
to report indentation, adds the <= token, and fixes some problems with
split-input-files in the errors.fir testcase.
 2020-03-21 23:09:53 -07:00
Chris Lattner 2f64d97d6e Finish up the lexer, at least far enough to be able to lex a very large 
firtl files, and add some testcases for errors.
 2020-03-20 13:06:00 -07:00
Chris Lattner d8726bd431 Implement a big chunk of a lexer for .fir files, including punctuation 
comments, keywords, etc.  The grammar for literals is wrong and largely
missing, but this gets a useful chunk of .fir files through the lexer.

This includes a silly test driver that shows things are getting properly
tokenized.
 2020-03-17 17:46:05 -07:00
Chris Lattner 588212f71d add a VS Code configuration. 2020-03-16 15:16:13 -07:00
Chris Lattner 2fe028d811 Implement the build and integeration outline of an spt-translate tool, 
and stub out a .fir parser (which doesn't do anything yet) that is driven
from it.
 2020-03-16 15:14:56 -07:00
Chris Lattner dfac4c84db Have the module printing logic consider whether the generated name is 
correct.  If not, generate a firrtl.name attribute explicitly to ensure
we round-trip correctly.

This depends on this unlanded MLIR patch: https://reviews.llvm.org/D76205
 2020-03-15 18:52:26 -07:00
Chris Lattner 233e04e710 Improve the README to include some contributor notes, clang-format 
the codebase.
 2020-03-15 17:59:29 -07:00
Chris Lattner c056bf088e Updates to work with MLIR ToT. 2020-03-12 22:57:37 -07:00
Chris Lattner 613ac5eb6c Do not print the firrtl.name attribute on parameters if we've managed 
to merge it into the argument list.
 2020-03-09 09:20:34 -07:00
Chris Lattner a906b944bf Implement the OpAsmDialectInterface interface for FIRRTL, enabling us to 
use the attribute names as the SSA names for things in dumps.
 2020-03-08 18:28:46 -07:00
Chris Lattner f7c63a5253 Convert module to being an an op that is FunctionLike, IsolatedFromAbove, Symbol. 
This adds the ability to model inputs and outputs.  The parsing side is nice,
but the printing side still needs to use the symbolic argument names.
 2020-03-08 12:44:23 -07:00
Chris Lattner 395b7bee7a Add a firrtl.connect op definition. 2020-03-07 23:14:19 -08:00
Chris Lattner ef84a84a6f Introduce a firrtl.invalid operation and give firrtl.add nicer syntax. 2020-03-07 23:10:55 -08:00
Chris Lattner 6dfa2793f0 Give circuit and module custom syntax, making them much nicer to read and write. 2020-03-07 19:51:52 -08:00
Chris Lattner 288b0c10c7 Introduce op definitions for module, circuit and a 'done' terminator. Add 
testcases to show things it catches.
 2020-03-07 19:27:37 -08:00
Chris Lattner 24c3b33447 Create the sketch of a FIRRTL dialect, with a single type (firrtl.uint) and a 
single registered operations (firrtl.add).  Add a testcase showing that these
are now being properly checked.
 2020-03-07 15:47:08 -08:00
Chris Lattner 71b7e2cb93 Add a sketch of a direct translation of a couple of examples of firrtl-in-mlir. 2020-03-06 17:27:04 -08:00
Chris Lattner 7783a53c8e Push the cmake files far enough along to make spt-opt be able to link in 
MLIR libraries, parsing and printing the output, running passes, etc.
 2020-03-06 16:42:00 -08:00
Chris Lattner 64cec97240 Introduce a CMakefile scaffolding to build and test an executable. 
This also updates the README to include some building information.

Lots of caveats:
 - This is all experimental
 - The actual tool isn't interesting yet.
 - The naming is arbitrary and will likely change.
 - Much of the cmake files were cargo culted from other places
   because I don't know what I'm doing.
