v0.1.15

Compare Source

Added

• [CyclesCount] counter to display cycle throughput as Hertz.
• Track the maximum number of bytes allocated during a benchmark.

Removed

• Remove has_cpuid polyfill due to it no longer being planned for Rust, since
  CPUID is assumed to be available on all old x86 Rust targets.

Fixed

• List generic benchmark type parameter A<4> before A<32> ([#​64]).

• Improve precision by using f64 when calculating allocation count and sizes
  for the median samples.

• Multi-thread allocation counting in sum_alloc_tallies on macOS was loading a
  null pointer instead of the pointer initialized by sync_threads.

Changes

• Sort all output benchmark names
  naturally instead of
  lexicographically.

• Internally reuse [&[&str] slice][slice] for [args] names.

• Subtract overhead of [AllocProfiler] from timings. Now that Divan also
  tracks the maximum bytes allocated, the overhead was apparent in timings.

• Simplify ThreadAllocInfo::clear.

• Move measured loop overhead from SharedContext to global OnceLock.

• Macros no longer rely on std being re-exported by Divan. Instead they use
  ::std or ::core to greatly simplify code. Although this is technically a
  breaking change, it is extremely unlikely to do extern crate std as x.
