The system call table in perf trace is used to map system call numbers to names and vice versa. Prior to these changes, a single table matching the perf binary's build was present. The table would be incorrect if tracing say a 32-bit binary from a 64-bit version of perf, the names and numbers wouldn't match. Change the build so that a single system call file is built and the potentially multiple tables are identifiable from the ELF machine type of the process being examined. To determine the ELF machine type, the executable's header is read from /proc/pid/exe with fallbacks to using the perf's binary type when unknown. Remove some runtime types used by the system call tables and make equivalents generated at build time. Ian Rogers (7): perf syscalltble: Remove syscall_table.h perf trace: Reorganize syscalls perf syscalltbl: Remove struct syscalltbl perf thread: Add support for reading the e_machine type for a thread perf trace beauty: Add syscalltbl.sh generating all system call tables perf syscalltbl: Use lookup table containing multiple architectures perf build: Remove Makefile.syscalls tools/perf/Makefile.perf | 10 +- tools/perf/arch/alpha/entry/syscalls/Kbuild | 2 -
