Despite the documentation and the comment in xtensa_move_literals, in the presence of --text-section-literals and --auto-litpools literals are moved from the separate literal sections into .init and .fini, because the check in the xtensa_move_literals is incorrect. This moving was broken with introduction of auto litpools: some literals now may be lost. This happens because literal frags emitted from .init and .fini are not closed when new .literal_position marks new literal pool. Then frag_align(2, 0, 0) changes type of the last literal frag to rs_align. rs_align frags are skipped in the xtensa_move_literals. As a result fixups against such literals are not moved out of .init.literal/ .fini.literal sections producing the following assembler error: test.S: Warning: fixes not all moved from .init.literal test.S: Internal error! Fix check for .init.literal/.fini.literal in the xtensa_move_literals and don't let it move literals from there in the presence of --text-section-literals or --auto-litpools. 2016-02-17 Max Filippov <jcmvbkbc@gmail.com> gas/ * config/tc-xtensa.c (xtensa_move_literals): Fix check for .init.literal/.fini.literal section name. * testsuite/gas/xtensa/all.exp: Add init-fini-literals to the list of xtensa tests. * testsuite/gas/xtensa/init-fini-literals.d: New file: init-fini-literals test result patterns. * testsuite/gas/xtensa/init-fini-literals.s: New file: init-fini-literals test. |
