* [llvm-cov] Make report metrics agree with line exec counts, fixes PR34615Vedant Kumar2017-09-198-125/+124
| | | | | | | | | Use the same logic as the line-oriented coverage view to determine the number of covered lines in a function. Fixes llvm.org/PR34615. llvm-svn: 313604
* [Coverage] Use gap regions to select better line exec countsVedant Kumar2017-09-183-9/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | After clang started emitting deferred regions (r312818), llvm-cov has had a hard time picking reasonable line execuction counts. There have been one or two generic improvements in this area (e.g r310012), but line counts can still report coverage for whitespace instead of code (llvm.org/PR34612). To fix the problem: * Introduce a new region kind so that frontends can explicitly label gap areas. This is done by changing the encoding of the columnEnd field of MappingRegion. This doesn't substantially increase binary size, and makes it easy to maintain backwards-compatibility. * Don't set the line count to a count from a gap area, unless the count comes from a wrapped segment. * Don't highlight gap areas as uncovered. Fixes llvm.org/PR34612. llvm-svn: 313597
* [llvm-cov] Simplify code to find the first uncovered segment. NFC.Vedant Kumar2017-09-181-14/+8
| | | | | | | Now that that segment builder is guaranteed to produce segments in sorted order, we don't need a linear scan to get the right result. llvm-svn: 313595

* [dwarfdump] Make .eh_frame an alias for .debug_frameJonas Devlieghere2017-09-183-6/+6
| | | | | | | | | | | | | | | | | | | | This patch makes the `.eh_frame` extension an alias for `.debug_frame`. Up till now it was only possible to dump the section using objdump, but not with dwarfdump. Since the two are essentially interchangeable, we dump whichever of the two is present. As a workaround, this patch also adds parsing for 3 currently unimplemented CFA instructions: `DW_CFA_def_cfa_expression`, `DW_CFA_expression`, and `DW_CFA_val_expression`. Because I lack the required knowledge, I just parse the fields without actually creating the instructions. Finally, this also fixes the typo in the `.debug_frame` section name which incorrectly contained a trailing `s`. Differential revision: https://reviews.llvm.org/D37852 llvm-svn: 313530
* [XRay][tools] Support tail-call exits before we write them in the runtimeDean Michael Berris2017-09-184-3/+12
| | | | | | | | | | | | | | | | | Summary: This change adds support for explicit tail-exit records to be written by the XRay runtime. This lets us differentiate the tail exit records/events in the log, and allows us to treat those exit events especially in the future. For now we allow printing those out in YAML (and reading them in). Reviewers: kpw, pelikan Subscribers: llvm-commits Differential Revision: https://reviews.llvm.org/D37964 llvm-svn: 313514

| | | | | | | | | | | | | | | | * Fix an unsigned integer overflow in the logic that computes the number of uncovered lines in a function. * When aggregating region and line coverage summaries, take into account that different instantiations may have a different number of regions. The new test case provides test coverage for both bugs. I also verified this change by preparing a coverage report for a stage2 build of llc -- the new assertions should detect any outstanding over-counting bugs. Fixes PR34613. llvm-svn: 313417

| | | | | | | | | | | | Since users typically don't really care about the .dwo / non.dwo distinction, this patch makes it so dwarfdump --debug-<info,...> dumps .debug_info and (if available) also .debug_info.dwo.

| | | | | | | | | | | | | | and a zero n_sect value. The code in llvm-nm for Mach-O files to determine the section type for an N_SECT type symbol it will call getSymbolSection() and check for the error, but in the case the n_sect value is zero it will return section_end() (aka nullptr).
