release notes 
This version comes with a new architecture support as well as
many bug fixes and various improvements.

RISC-V Architecture Support


uftrace can trace functions of RV64G binaries compiled by gcc/clang with

appropriate options (-pg or -finstrument-functions).  Library functions

are also traced and you can see the arguments and return values too.

(There are issues in argument handling, but library functions should be

fine.)  However dynamic tracing is not supported yet.


$ uftrace --force -a -t 3us -- uname -m
riscv64
# DURATION     TID     FUNCTION
 263.004 us [138960] | strrchr("uname", '/') = "NULL";
  87.751 us [138960] | setlocale(LC_ALL, "") = "NULL";
   5.000 us [138960] | bindtextdomain("coreutils", "/usr/share/locale");
   4.000 us [138960] | getopt_long(2, 0x3fecdcf328, "asnrvmpio") = 109;
   4.000 us [138960] | uname();
   8.250 us [138960] | fputs_unlocked();
 443.257 us [138960] | __overflow();
   3.250 us [138960] | __fpending();
   4.500 us [138960] | fclose(&_IO_2_1_stdout_) = 0;



Other Notable Improvements


As libtraceevent is available on recent distros, the kernel tracing uses

the system installed library and drops the old copy in the uftrace source.

This should help resolving possible future kernel issues and reduce the

maintenance burden.


Also some distros build binaries without PLT and it can confuse uftrace

about the library call tracing.  It now detects the case by verifying

PLT entries not to miss library calls without it.
