[This patch should go on top of "linux_qxfer_libraries_svr4: Use std::string", I should have sent them together as a series.] I noticed that linux_qxfer_libraries_svr4 used xml_escape_text, which returns an std::string. That string is then copied into a larger buffer. It would be more efficient if we had a version of xml_escape_text which appended to an existing string instead of returning a new one. This is what this patch does. I manually verified that the output of linux_qxfer_libraries_svr4 didn't change before/after the patch. gdb/ChangeLog: * common/xml-utils.c (xml_escape_text): Move code to... (xml_escape_text_append): ... this new function. * common/xml-utils.h (xml_escape_text_append): New declaration. * unittests/xml-utils-selftests.c (test_xml_escape_text_append): New function. (_initialize_xml_utils): register test_xml_escape_text_append as a selftest. gdb/gdbserver/ChangeLog: * linux-low.c (linux_qxfer_libraries_svr4): Use xml_escape_text_append.
