Masatake YAMATO 2bb35360c2 mmap_cache: move code for searching a mmap cache from unwind
print_stack_frame function in unwind.c searches a mmap entry in mmap
cache.  The found entry is then used for unwinding.  However, a function
searching for a mmap entry may be useful for other purposes than
unwinding.

This change re-factors the function; code for searching an entry is
now defined as a stand-alone function named mmap_cache_search.

* defs.h (mmap_cache_search): New function prototype.
print_stack_frame.
* mmap_cached.c (mmap_cache_search): New function derived from
print_stack_frame.
* unwind.c (print_stack_frame): Use it.

strace - the linux syscall tracer

This is strace -- a diagnostic, debugging and instructional userspace utility with a traditional command-line interface for Linux. It is used to monitor and tamper with interactions between processes and the Linux kernel, which include system calls, signal deliveries, and changes of process state. The operation of strace is made possible by the kernel feature known as ptrace.

strace is released under a Berkeley-style license at the request of Paul Kranenburg; see the file COPYING for details.

See the file NEWS for information on what has changed in recent versions.

Please read the file INSTALL-git for installation instructions.

The user discussion and development of strace take place on the strace mailing list -- everyone is welcome to post bug reports, feature requests, comments and patches to strace-devel@lists.strace.io. The mailing list archives are available at https://lists.strace.io/pipermail/strace-devel/ and other archival sites.

The GIT repository of strace is available at GitHub and GitLab.
