Changes in Makefile http://nxr.netbsd.org/rss/src/tests/usr.bin/gcov/Makefile en Copyright 2005 Java tests/gcov: demonstrate wrong coverage report after vfork/exec<br/><br/>Discovered in usr.bin/make, function Cmd_Exec.<br/><br/>The coverage test I ran on 2024-07-13 was still good. I don't remember<br/>the exact version of NetBSD-current I was running back then.<br/><br/>With NetBSD-current from 2025-01-17, gcov does not report full coverage<br/>data after a vfork/exec call. Running the test program inside ktrace<br/>shows that after a vfork call, the child process writes its coverage data<br/>back, probably right before the exec call, but the parent process<br/>doesn't.<br/><br/>Running a child process through system(3) is not affected; there,<br/>posix_spawn is used instead of vfork/exec. /src/tests/usr.bin/gcov/Makefile - 1.1 Sat Jan 18 22:31:22 UTC 2025 rillig
