- * libgcov.c (create_file_directory): New function.
- (gcov_prefix): New static variable to hold data file

- (gcov_version): Use relocation prefix.
- (gcov_exit): Always try to create directory for output

- (__gcov_init): Initialize directory relocation prefix
- if required. Strip off leading directories from
- the initial filename.
- * tsystem.h: include filenames.h
- (DIR_SEPARATOR): Macro copied from system.h.
- (DIR_SEPARATOR_2): Likewise.
- * doc/gcov.texi (Cross-profiling): New node documenting
- cross-profiling management.

-+@section Data files relocation to support cross-profiling
-+
-+Running the program will cause profile output to be generated. For each
-+source file compiled with @option{-fprofile-arcs}, an accompanying @file{.gcda}
-+file will be placed in the object file directory. That implicitly requires
-+running the program at the same system as it was build or having same
-+absolute directory structure on the target system (program will try
-+to create needed directory structure).
-+
-+To support cross-profiling, program compiled with @option{-fprofile-arcs}
-+performs data file relocation basing on two environment variables:
-+
-+@itemize @bullet
-+@item
-+GCOV_PREFIX contains the prefix to add to the absolute paths
-+in the object file.
-+
-+@item
-+GCOV_PREFIX_STRIP indicates the how many initial directory names to strip off
-+the hardwired absolute paths. Default value is 0.
-+@end itemize
-+
-+For example, if object file @file{/user/build/foo.o} was build with
-+@option{-fprofile-arcs}, the final executable will try to create data file
-+@file{/user/build/foo.gcda} when running at the target system and will
-+fail if corresponding directory does not exists and is not allowed to create.
-+
-+In this case, manipulating environment variables you can relocate data file
-+to the suitable local directory. For our example, setting @samp{GCOV_PREFIX=/target/run}
-+and @samp{GCOV_PREFIX_STRIP=1} values will force use of @file{/target/run/build/foo.gcda}
-+file name.
