The DWARF reader currently sets the CU's language in two different spots. It is primarily done in prepare_one_comp_unit, but read_file_scope also checks the producer and may change the language based on the result. This patch consolidates all language-setting into prepare_one_comp_unit. set_cu_language is renamed and changed not to set language_defn; instead that is done in prepare_one_comp_unit after the correct language enum value is chosen. This fixes a minor latent bug, which is that read_file_scope could set the language enum value to language_opencl, but then neglected to reset language_defn in this case. gdb/ChangeLog 2021-06-25 Tom Tromey <tom@tromey.com> * dwarf2/read.c (read_file_scope): Don't call set_cu_language. (dwarf_lang_to_enum_language): Rename from set_cu_language. Don't set language_defn. Handle DW_LANG_OpenCL. (prepare_one_comp_unit): Check producer and set language_defn.
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.
