Change default print level to info.
2016-04-16Add Namespace for thread-safe creation of names and temporary namesjackkoenig
Replace use of gensym with local namespaces Delete gensym
2016-04-16Add useful traits for Names and Declarationsjackkoenig
2016-04-16Add safety to Visitor.visitStmt to first check for TerminalNodejackkoenig
Fixes ucb-bar/chisel3#87
2016-04-15Fix Verilog emission for Modelsim compliationAndrew Waterman
Statements like: if (foo) x <= y; end else begin ; end are now emitted without the else clause: if (foo) x <= y; end and statements like: if (foo) ; end else begin x <= y; end are now emitted without the empty statement: if (foo) end else begin x <= y; end
2016-04-14Improve performance of CSE passAndrew Waterman
Repeated calls to hashCode take most of the runtime, so cache it.
2016-04-14Factor DCE re-running more cleanlyAndrew Waterman
2016-04-14Add CSE passAndrew Waterman
2016-04-13Extend mux constant propagationAndrew Waterman
2016-04-13Add shift/concat constant propagationAndrew Waterman
2016-04-09Adds check for type of DefRegister initializationjackkoenig
Fixes #89
2016-04-09Fix bundle type equalityAdam Izraelevitz
Was not checking for length of bundles, so if the bundles matched but one had more fields, it was not caught.
2016-04-08Fixed bug in Remove Accesses where a WSubAccess's index was not checked for ↵Adam Izraelevitz
accesses. Fixes #105
2016-04-07Add primitive dead code elimination passAndrew Waterman
2016-04-07Split ConstProp pass into own file; propagate lits through nodesAndrew Waterman
2016-04-07Add constant propagation for muxes on UIntAndrew Waterman
2016-04-07Add basic constant propagation for logical operatorsAndrew Waterman
This is deliberately incomplete because I wanted to get feedback before plowing ahead. These passes handle constant propagation for bitwise and equality operators on UInt only, usually only when the widths match.
2016-04-07Make ConstProp pass more conciseAndrew Waterman
I was going to augment it, but thought it best to clean it up first.
2016-04-06Merge pull request #102 from ucb-bar/propagate-mem-port-typesAdam Izraelevitz
Propagate memory port types in Emitter
2016-04-04Wrapped delay in ifndef verilator, as it is not supported by verilatorAdam Izraelevitz
2016-04-01Propagate memory port types in EmitterAndrew Waterman
Don't just use UnknownType() everywhere.

2016-02-25Remove unused code in Driver, update help messagejackkoenig
2016-02-24Fixed printf bugs in scala and stanza versions. Required special casing ↵Adam Izraelevitz
prints in SplitExp, and emitting expressions instead of their toString counterparts
2016-02-24Quick fix for printf in the emitted VerilogKamyar Mohajerani
2016-02-23Change FIRRTL Compiler to remove CHIRRTL and Check High FIRRTL FormJack
2016-02-23Stop closing writers in compiler, close in Driver instead (allows others to ↵Jack
use StringWriters without the Compiler closing it)
2016-02-22Temporary Fix: get_type on depth=1 memories causing IntWidth(0) typesJack

IntLits (all IntLits handled by Parser and Visitor the same, checks come later), also delete first and last char of string literals since those characters are the quotes.
2016-02-09Added migrated HighFormCheck to Scala FIRRTL, changes to IR and Utils for ↵Jack
