2016-10-25Implement ~line_maps ()David Malcolm2-1/+5
line_maps instances such as the global line_table are GC-managed, but the htab within location_adhoc_data_map.htab is not GC-managed. Previously this was deleted manually by a call to location_adhoc_data_fini within toplev::main. However, on adding a call to forcibly_ggc_collect after the selftests, all of the htabs for the various line_tables created during the selftests start showing up as leaks in "make selftest-valgrind", e.g.: 13,536 (1,344 direct, 12,192 indirect) bytes in 12 blocks are definitely lost in loss record 1,065 of 1,086 at 0x4A081D4: calloc (in /usr/lib64/valgrind/vgpreload_memcheck-amd64-linux.so) by 0x16DB3B0: xcalloc (xmalloc.c:163) by 0x16D8D34: htab_create_typed_alloc (hashtab.c:358) by 0x16D8DBD: htab_create_alloc (hashtab.c:286) by 0x16A2CCC: linemap_init(line_maps*, unsigned int) (line-map.c:353) by 0x1685605: selftest::line_table_test::line_table_test(selftest::line_table_case const&) (input.c:1624) by 0x167D09C: selftest::test_applying_fixits_modernize_named_init(selftest::line_table_case const&) (edit-context.c:1430) by 0x1686827: selftest::for_each_line_table_case(void (*)(selftest::line_table_case const&)) (input.c:3227) by 0x167F067: selftest::edit_context_c_tests() (edit-context.c:1658) by 0x1616E67: selftest::run_tests() (selftest-run-tests.c:71) by 0xC0DB25: toplev::run_self_tests() (toplev.c:2076) by 0x618EB4: toplev::main(int, char**) (toplev.c:2153) This patch removes the manual one-time cleanup in favor of adding a destructor to class line_maps, which cleans up the non-GC-managed htab.

2016-10-25With -fpu=neon DI mode shifts are expanded after reload.Wilco Dijkstra4-22/+58
With -fpu=neon DI mode shifts are expanded after reload. DI mode registers can either fully or partially overlap on both ARM and Thumb-2. However the shift expansion code can only deal with the full overlap case, and generates incorrect code for partial overlaps. The fix is to add new variants that support either full overlap or no overlap. gcc/ PR target/78041 * config/arm/neon.md (ashldi3_neon): Add "r 0 i" and "&r r i" variants.
