2021-02-11Fix stack trace trimming across Driver/ChiselStage (#1771)Schuyler Eldridge
* Handle MemTypeBinding in Analog Signed-off-by: Schuyler Eldridge <schuyler.eldridge@sifive.com> * Fix stack trace trimming across ChiselStage Fix bug in stack trace trimming behavior. Now, the following is what happens: 1. The Builder, if catching accumulated errors, will now throw a ChiselException with a Scala-trimmed Stack trace. Previously, this would throw the full excpetion. 2. The Elaborate phase handles stack trace trimming. By default, any Throwable thrown during elaboration will have its stack trace *mutably* trimmed and is rethrown. A logger.error is printed stating that there was an error during elaboration and how the user can turn on the full stack trace. If the --full-stacktrace option is on, then the Throwable is not caught and only the first logger.error (saying that elaboration failed) will be printed. 3. ChiselStage (the class), ChiselStage$ (the object), and ChiselMain all inherit the behavior of (2). Mutable stack trace trimming behavior is moved into an implicit class (previously this was defined on ChiselException only) so this can be applied to any Throwable. No StageErrors are now thrown anymore. However, StageErrors may still be caught by ChiselMain (since it is a StageMain). Testing is added for ChiselMain, ChiselStage, and ChiselStage$ to test all this behavior. Signed-off-by: Schuyler Eldridge <schuyler.eldridge@sifive.com>

2019-05-20Repackagecore rebase (#1078)Jim Lawson
* Move Bits, Data, and BitPat to chiselFrontend/src/main/scala/chisel3 and deal with the subsequent fallout. * Move Aggregate, Clock, Mem, Printf, Reg * Move almost all chisel3.core definitions to chisel3 or chisel3.experimental * Revive core package object to provide aliases for moved definitions. * Cleanup package definitions; eliminate ambiguous implicits * Move more definitions to experimental. Extract BaseModule, DataMirror, ExtModule, IO into their own files. * Put BitPat back in chisel3.util * More experimental motion - avoid multiple import definitions. * Add experimental.FixedPoint alias * Add EnumType definition to core package. Update deprecated messages to refer to correct object * Move FixedPoint into the experimental package (but keep it in Bits.scala). * Add missing implicits to core/package - compatibility * Cleanup: update ScalaDoc references; remove unused imports * Add Reset alias to core/package * Use common 3.2 version in deprecation warning * Move Binding from core to internal. * Optimize imports. * Repair IntelliJ's overly cleanliness. * Move Bits, Data, and BitPat to chiselFrontend/src/main/scala/chisel3 and deal with the subsequent fallout.

Use "scalastyle-test-config.xml" for scalastyle config in tests. Enable "_" in method names and accept method names ending in "_=". Re-sync scalastyle-test-config.xml with scalastyle-config.xml This should finally fix #772. * Check field referential equality in autoclonetype (#1047) * Allow naming annotation to work outside builder context (#1051) * Try to eliminate JVM hang due to static initialization deadlock (#1053) * Make core.DontCare private to chisel3 (#1054) Force clients to access 'DontCare' through the chisel3 package to ensure it's created as a chisel3 object and not a client object. * Ignore empty aggregates elements when binding aggregate direction (#946) Previously, including an empty aggregate in a Bundle would cause a MixedDirectionAggregateException because it has no elements and thus doesn't have a direction * Add SampleElementBinding for Vec sample elements * Add ActualDirection.Empty for bound empty aggregates * Detect bundle aliasing (#1050) * Implement connectFromBits in ChiselEnum (#1052) This is necessary to use ChiselEnum in aggregates where things are casted using .asTypeOf * Optimize imports. * Move Analog to experimental. * More repackage cleanup - reduce differences with master. * Cleanup chisel3 references. * More chisel3 reference cleanup. * Merge cleanup. * Remove unused import * Bump core deprecation to 3.3 * Move DontCare back into Data.scala inside package internal * Re-indent experimental/internal package code * Move code back to original files - facilitate comparison with other branches * Some code motion, update imports, minimize master differences Move exceptions up to chisel3 package object - they're part of the interface. * More master diff minimization. * Try to eliminate JVM hang due to static initialization deadlock (#1053) * Ignore empty aggregates elements when binding aggregate direction (#946) Previously, including an empty aggregate in a Bundle would cause a MixedDirectionAggregateException because it has no elements and thus doesn't have a direction * Add SampleElementBinding for Vec sample elements * Add ActualDirection.Empty for bound empty aggregates * Implement connectFromBits in ChiselEnum (#1052) This is necessary to use ChiselEnum in aggregates where things are casted using .asTypeOf * Move Analog to experimental.

More master diff minimization. Fix minor discrepancies with repackagecore-testbed * Remove redundant imports As part of its import updating process, IntelliJ converted some import statements to `import package.{object, _}`. Is this intended to show an explicit dependency on `package.object` and a further dependency on `package` implicits? Unsure. Replace these with `import package._` * Move the BaseModule object into the internal package.

* still trying to find right mix * Making some progress on Mux1H * Mux1H that works in non-optimzed fashion for FixedPoint, works pretty well in general Catches some additional problem edge cases Some tests that illustrate most of this * Moved in Angie's code for handling FixedPoint case Cleaned up tests considerably, per @ducky64 review * Just a bit more cleanup
