Several GDB tests change directory before compiling the test program
in order to test source file names that include directories. This
doesn't work on a remote host because default_target_compile in
DejaGnu's target.exp copies each source file with
"[remote_download host $x]" which uses "[file tail $file] to strip
off the directory of each file. If the source directory is remote
mounted on the host, this also leaves copied files in the source
directory.
A similar skip is already used in gdb.test/fullname.exp:
# We rely on being able to copy things around.
if { [is_remote host] } {
untested "setting breakpoints by full path"
return -1
}
This patch causes three GDB tests that use "cd" to be skipped for a
remote host. For gdb.base/fullpath-expand.exp this eliminates two
failures and prevents the test from leaving files fullpath-expand.c
and fullpath-expand-func.c in gdb/testsuite. For
gdb.base/realname-expand.exp it eliminates two failures. For
gdb.linespec/macro-relative.exp it prevents file macro-relative.c
from being left in gdb/testsuite/gdb.linespec/base/two.
gdb/testsuite/
* gdb.base/fullpath-expand.exp: Skip for a remote host.
* gdb.base/realname-expand.exp: Likewise.
* gdb.linespec/macro-relative.exp: Likewise.
* dwarf2read.c (dw2_expand_symtabs_matching): Add basenames parameter
to the file_matcher parameter. Pass 0 to it.
(dwarf2_create_include_psymtab): Copy also DIRNAME.
* psymtab.c (partial_map_symtabs_matching_filename): Drop handling of
NULL psymtab_to_fullname result.
(psymtab_to_fullname): Remove variable r. Never return NULL, assemble
an expected filename instead.
(expand_symtabs_matching_via_partial): Add basenames parameter to the
file_matcher parameter. Call also psymtab_to_fullname, after newly
considering BASENAMES_MAY_DIFFER.
* source.c (rewrite_source_path): Remove static.
* source.h (rewrite_source_path): New declaration.
* symfile.h (struct quick_symbol_functions): Add basenames parameter to
the expand_symtabs_matching field. Comment it.
* symtab.c (file_matches): New function comment. Add parameter
basenames, implement it.
(search_symbols_file_matches): Add basenames parameter. Update the
file_matches caller.
(search_symbols): Match FILES also against symtab_to_fullname.
Optimize it for BASENAMES_MAY_DIFFER.
