Cleaning up the subsym_hash memory is a real pain. Keys and values entered into the table are quite diverse. In some cases the key is allocated and thus needs to be freed, in others the key is a const string. Values are similar, and in some cases not even a string. Tidy this by inserting a new subsym_ent_t that describes key/value type. This meant the math_hash table was no longer needed. The patch also tidies how math functions are called, those that are supposed to return int now no longer return their value in a float. * config/tc-tic54x.c (math_hash): Delete. (subsym_proc_entry): Move earlier, make proc a union, merge with.. (math_proc_entry): ..this. Delete type. (math_procs): Merge into subsym_procs. (subsym_ent_t): New. Use this type in subsym_hash.. (stag_add_field_symbols, tic54x_var, tic54x_macro_info): ..here.. (md_begin, subsym_create_or_replace, subsym_lookup): ..and here.. (subsym_substitute): ..and here. Adjust subsym_proc_entry function calls. Free replacement when not returned. (subsym_get_arg): Adjust subsym_lookup. (free_subsym_ent, subsym_htab_create ): New functions, use when creating subsym_hash. (free_local_label_ent, local_label_htab_create): Similarly. (tic54x_remove_local_label): Delete. (tic54x_clear_local_labels): Simplify. (tic54x_asg): Use notes obstack to dup strings. (tic54x_eval): Likewise. (subsym_ismember): Likewise. (math_cvi, math_int, math_sgn): Return int. (tic54x_macro_start): Decrement macro_level before calling as_fatal. (tic54x_md_end): New function. * config/tc-tic54h.c (tic54x_md_end): Declare. (md_end): Define.

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.
