On powerpc64, qSymbol for a function returns the function code address, and not the descriptor address. Since we emit code calling gdb_collect and some other functions, we need the descriptor (no way to know the proper TOC address without it). To get the descriptor address, make global function pointer variables in the IPA pointing to the relevant functions and read them instead of asking for them directly via qSymbol. gdb/gdbserver/ChangeLog: * linux-aarch64-ipa.c: Rename gdb_agent_get_raw_reg to get_raw_reg. * linux-amd64-ipa.c: Likewise. * linux-i386-ipa.c: Likewise. * linux-s390-ipa.c: Likewise. * tracepoint.c: IPA-export gdb_collect_ptr instead of gdb_collect, ditto for get_raw_reg_ptr, get_trace_state_variable_value_ptr, set_trace_state_variable_value_ptr. (struct ipa_sym_addresses): Likewise. (symbol_list): Likewise. (install_fast_tracepoint): Dereference gdb_collect_ptr instead of accessing gdb_collect directly. (gdb_collect_ptr_type): New typedef. (get_raw_reg_ptr_type): New typedef. (get_trace_state_variable_value_ptr_type): New typedef. (set_trace_state_variable_value_ptr_type): New typedef. (gdb_collect_ptr): New global. (get_raw_reg_ptr): New global. (get_trace_state_variable_value_ptr): New global. (set_trace_state_variable_value_ptr): New global. (get_raw_reg_func_addr): Dereference get_raw_reg_ptr instead of accessing get_raw_reg directly. (get_get_tsv_func_addr): Likewise for get_trace_state_variable_value_ptr. (get_set_tsv_func_addr): Likewise for set_trace_state_variable_value_ptr. * tracepoint.h: Rename gdb_agent_get_raw_reg to get_raw_reg.
README for GNU development tools This directory contains various GNU compilers, assemblers, linkers, debuggers, etc., plus their support routines, definitions, and documentation. If you are receiving this as part of a GDB release, see the file gdb/README. If with a binutils release, see binutils/README; if with a libg++ release, see libg++/README, etc. That'll give you info about this package -- supported targets, how to use it, how to report bugs, etc. It is now possible to automatically configure and build a variety of tools with one command. To build all of the tools contained herein, run the ``configure'' script here, e.g.: ./configure make To install them (by default in /usr/local/bin, /usr/local/lib, etc), then do: make install (If the configure script can't determine your type of computer, give it the name as an argument, for instance ``./configure sun4''. You can use the script ``config.sub'' to test whether a name is recognized; if it is, config.sub translates it to a triplet specifying CPU, vendor, and OS.) If you have more than one compiler on your system, it is often best to explicitly set CC in the environment before running configure, and to also set CC when running make. For example (assuming sh/bash/ksh): CC=gcc ./configure make A similar example using csh: setenv CC gcc ./configure make Much of the code and documentation enclosed is copyright by the Free Software Foundation, Inc. See the file COPYING or COPYING.LIB in the various directories, for a description of the GNU General Public License terms under which you can copy the files. REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info on where and how to report problems.
