allocbench/src/exec.c, branch wait4_rusage benchmark tool for POSIX memory allocators implement alternative way to get memusage using wait4 2019-08-15T17:27:59+00:00 Florian Fischer florian.fl.fischer@fau.de 2019-08-15T17:27:59+00:00 b9cd13fedd8f077ecdd37857323eddddac285bc8 run now forks the benchmark command instead of simply calling exec. Ressource usage of the benchmark is retrieved with a call to wait4. But the reported value ru_maxrss differs from values in /proc/<pid>/status.

use LD_LIBRARY_PATH for glibc instead of calling its loader 2019-08-12T09:10:15+00:00 Florian Fischer florian.fl.fischer@fau.de 2019-08-12T09:10:15+00:00 c6a768c12ce7e83631d08f53937a075c4f76e2d5 Calling the loader fails on non ELF executables. Exec, formerly run_cmd, now takes two options: -l LD_LIBRARY_PATH, -p LD_PRELOAD. -p sets LD_PRELOAD and -l LD_LIBRARY_PATH before executing the rest of argv. glibc no longer uses cmd_prefix in favor of LD_LIBRARY_PATH.
