[0.7.0] - 2024-08-05

Added

LLVM 19 support (ignores function entry coverage and some failing proftext files)

[0.6.0] - 2024-05-17

Added

Added the ability to filter out certain sections from the generated coverage reports

Changed

Now use some hashmap based caching to speedup record lookup during profile merge.

[0.5.0] - 2024-04-28

Changed

Now allow binaries to fail parsing for the mapping information (depdendent on function argument)

[0.4.0] - 2024-04-12

Added

LLVM 17 and 18 support (test fails still: check_mapping_consistency but tarpaulin tests all pass so nearly all working)

Changed

Removed another two redundant hash computations

[0.3.3] - 2023-04-04

Changed

Cache name hash calculation to avoid recomputing (perf)

[0.3.2] - 2023-03-29

Added

llvm-16 test files to ensure support doesn't break

Fixed

Fixed parsing of branch region counters

[0.3.1] - 2023-01-23

Added

Debug logging via tracing

Fixed

Build on 32 bit architectures

[0.3.0] - 2022-09-26

Added

InstrumenationProfile::is_empty to detect when there are no records
Fuzzing module for profile files

Changed

Added anyhow and use in place of Result<T, Box<dyn Error>>
Make error type for profiles VerboseError

Fixed

Handle merging of completely disjoint records - now profiles generated from multiple applications are accurately merged
Handle invalid Hash enum variant in IndexedProfile

[0.2.0] - 2022-09-11

Changed

Made instrumentation profile parsing failure message more serious
Made hit adding in report use saturating_add to prevent overflow

Fixed

Make counter value signed when tracking expressions to prevent underflow
Multiply max counters by counter size when comparing to counter delta
Fixed handling of profile instrumentation not tied to a counter with source location
Incorrect matching on hashes for instrumentation profile merging

[0.1.1] - 2022-06-26

Added

Detection of memory profiling

Fixed

Counter offsetting in raw profiles now implemented
Counter size for byte coverage now correct
Text profile now handles carriage returns

[0.1.0] - 2022-06-05

Added

Parsing of indexed, text and raw profiles (llvm version 11, 12, 13, 14)
Parsing of instrumented binary and generating line coverage reports
