2021-06-10Stop Emitting BlackBoxResourceAnno (#1954)Schuyler Eldridge
* Change HasBlackBoxResource to Resolve Resources Change HasBlackBoxResource to resolve resources immediately and emit BlackBoxInlineAnno instead of a BlackBoxResourceAnno. This removes the need for a FIRRTL compiler to grok the Java Resource API in order to handle BlackBoxResourceAnno. Emit BlackBoxInlineAnno from HasExtModuleResource instead of BlackBoxResourceAnno.

2021-05-09Fix ShiftRegister with 0 delay. (#1903)Jiuyang Liu
* Add test to check ShiftRegister(s) with delay is 0. This should break ShiftRegister(x, 0) since last is not exist in a empty Seq. Originally, test only test 1 to 4, which missed a potential bug from #1723. * Fix ShiftRegister with 0 delay. if ShiftRegisters is empty, java will complain: ``` java.util.NoSuchElementException scala.collection.LinearSeqOptimized.last(LinearSeqOptimized.scala:150) ``` This fix this issue and return `in` directly when ShiftRegister size is 0.

2020-01-22Change when/switch thunk type to Any (#1308)Schuyler Eldridge
* Change when thunks return type to Any Changes the type of the thunk for when and WhenContext methods from call-by-name Unit to call-by-name Any. This prevents a warning (-Ywarn-value-discard) where a when thunk is returning something other than Unit that is then discarded, e.g., another WhenContext. Signed-off-by: Schuyler Eldridge <schuyler.eldridge@ibm.com> * Change switch thunk return to type to Any Changes the type of switch thunks from call-by-name Unit to call-by-name Any. This prevents a warning (-Ywarn-value-discard) when the internals of a switch block return something other than Unit which is then discarded.

2019-12-18BitPat supports whitespace and underscores, presumably for human readability.chick

2019-11-05Don't use MuxLookup default for full mappingSchuyler Eldridge
This modifies MuxLookup to not use the 'default' mapping argument if a "full" mapping is provided. A "full" mapping enumerates all possible cases for a 'key' argument of a known size. This will check literal values to ensure exhaustiveness holds.

2019-10-21Fix BoringUtils.bore for internal boringSchuyler Eldridge
This fixes a bug where internal boring using BoringUtils.bore would fail because it was using instanceName which cannot be called before the module closes. Previously, this meant that BoringUtils.bore would work for boring instances (which are closed in a parent), but not for boring signals in the current, unclosed module.
