2022-12-06Enhance find heap bound (#2579)Jack Koenig
* Enhance find_heap_bound to not go smaller than min_step Previously, it could accidentally get a step size smaller than the min_step and just continue looping forever. Now the while loop has a new termination condition to catch this case. * Add context to find_heap_bound This new option allows for checking additional heap sizes in increments of the min_step above the found minimum heap size.

2020-07-08dedup: use structural sha256 hash instead of agnostify and serialize (#1731)Kevin Laeufer
* benchmark: add hot.DedupBenchmark * dedup: use structural md5 hash instead of agnostify and serialize * StructuralHash: generate PrimOp LUT * StructuralHash: change MessageDigestHasher to not be a case class * StructuralHash: we want Blocks and EmptyStmt to be ignored * StructuralHash: use SHA-256 instead of MD5 * StructuralHash: clarify extmodule port name agnistification * StructuralHash: hash the name of width vars instead of trying to agnostify This should be in line with the old Dedup behavior. The prior use of n(..) was incorrect since the namespace of these vars is different from the normal module scope namespace. * StructuralHash: address Schuyler's review comments Co-authored-by: mergify[bot] <37929162+mergify[bot]@users.noreply.github.com>
2020-07-08ir: add faster serializer (#1694)Kevin Laeufer
This Serializer which is implemented external to the IR node definition uses a StringBuilder to achieve about a 1.7x performance improvement when serializing. Eventually, all implementations of the `serialize` methd should be replaced with a call to `Serializer.serialize`. However, for this PR we keep the old code in place in order to allow for easy regression testing with the benchmark JAR like this: > java -cp utils/bin/firrtl-benchmark.jar \ firrtl.benchmark.hot.SerializationBenchmark \ ~/benchmarks/medium.pb 2 5 test Co-authored-by: mergify[bot] <37929162+mergify[bot]@users.noreply.github.com>
2020-06-25Batch renames in LowerTypes (#1718)Schuyler Eldridge
* Batch renames in LowerTypes Signed-off-by: Schuyler Eldridge <schuyler.eldridge@ibm.com> * Add benchmarking for LowerTypes Add infrastructure of benchmarking Transforms (in addition to existing infra for Passes). Also run System.gc between each timed benchmark to improve stability. Co-authored-by: Jack Koenig <koenig@sifive.com> Co-authored-by: mergify[bot] <37929162+mergify[bot]@users.noreply.github.com>
