Literal movement code may grow auto litpool so big that it won't be possible to jump around it. Limit the size of auto litpools by 1/2 of the jump range. gas/ 2018-02-20 Max Filippov <jcmvbkbc@gmail.com> * config/tc-xtensa.c (struct litpool_frag): Add new field literal_count. (MAX_AUTO_POOL_LITERALS, MAX_EXPLICIT_POOL_LITERALS) (MAX_POOL_LITERALS): New macro definitions. (auto_litpool_limit): Initialize to 0. (md_parse_option): Set auto_litpool_limit in the presence of --auto-litpools option. (xtensa_maybe_create_literal_pool_frag): Zero-initialize literal_count field. (xg_find_litpool): New function. Make sure that found literal pool size is within the limit. (xtensa_move_literals): Extract literal pool search code into the new function. * testsuite/gas/xtensa/all.exp: Add auto-litpools-2 test. * testsuite/gas/xtensa/auto-litpools-2.d: New file. * testsuite/gas/xtensa/auto-litpools-2.s: New file. * testsuite/gas/xtensa/auto-litpools.d: Fix up changed addresses. * testsuite/gas/xtensa/auto-litpools.s: Change literal value so that objdump doesn't get out of sync.
