Auto-litpools is the automated version of text-section-literals: literal pool candidate frags are planted every N frags and during relaxation they are turned into actual literal pools where literals are moved to become reachable for their first reference by L32R instruction. 2015-08-12 David Weatherford <weath@cadence.com> gas/ * config/tc-xtensa.c (struct litpool_frag, struct litpool_seg): New structures. (xtensa_maybe_create_literal_pool_frag): New function. (litpool_seg_list, auto_litpools, auto_litpool_limit) (litpool_buf, litpool_slotbuf): New static variables. (option_auto_litpools, option_no_auto_litpools) (option_auto_litpool_limit): New enum identifiers. (md_longopts): Add entries for auto-litpools, no-auto-litpools and auto-litpool-limit. (md_parse_option): Handle option_auto_litpools, option_no_auto_litpools and option_auto_litpool_limit. (md_show_usage): Add help for --[no-]auto-litpools and --auto-litpool-limit. (xtensa_mark_literal_pool_location): Record a place for literal pool with a call to xtensa_maybe_create_literal_pool_frag. (get_literal_pool_location): Find highest priority literal pool or convert candidate to literal pool when auto-litpools are used. (xg_assemble_vliw_tokens): Create literal pool after jump instruction. (xtensa_check_frag_count): Create candidate literal pool every auto_litpool_limit frags. (xtensa_relax_frag): Add jump around literals to non-empty literal pool. (xtensa_move_literals): Estimate literal pool addresses and move unreachable literals closer to their users, converting candidate to literal pool if needed. (xtensa_switch_to_non_abs_literal_fragment): Only emit error about missing .literal_position in case auto-litpools are not used. * config/tc-xtensa.h (xtensa_relax_statesE): New relaxation state: RELAX_LITERAL_POOL_CANDIDATE_BEGIN. * doc/as.texinfo (Xtensa options): Document --auto-litpools and --no-auto-litpools options. * doc/c-xtensa.texi (Xtensa options): Likewise. 2015-08-12 Max Filippov <jcmvbkbc@gmail.com> gas/testsuite/ * gas/xtensa/all.exp: Add auto-litpools to the list of xtensa tests. * gas/xtensa/auto-litpools.s: New file: auto-litpools test. * gas/xtensa/auto-litpools.s: New file: auto-litpools test result pattern. |

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.
