PR24511, nm should not mark symbols in .init_array as "t" This patch restricts the section names matched in coff_section_type, a function that translates section names to symbol type, and arranges to translate section flags to symbol type before looking at names. The latter change resulted in various test failures due to improper section flags being used in tests, and by the plugin support, so fix that too. The new test fails on many ELF targets that lack .init/fini_array in their scripts. I've just xfailed those. pru-elf oddly defines __init_array_begin rather than __init_array_start. I've left that target as a FAIL, and pj-elf too which reports an error for undefined weak symbols. bfd/ PR 24511 * syms.c (coff_section_type): Only allow '.', '$' and numeric following the standard section names. (bfd_decode_symclass): Prioritize section flag tests in decode_section_type before name tests in coff_section_type. * plugin.c (bfd_plugin_canonicalize_symtab): Init fake_section and fake_common_section using BFD_FAKE_SECTION. Use "fake" as their names and choose standard .text section flags for fake_section. ld/ PR 24511 * testsuite/ld-elf/pr14156a.d: Allow for .init/.fini being a data section on hppa64. * testsuite/ld-elf/pr14156b.d: Likewise. * testsuite/ld-scripts/pr18963.t: Map standard sections to set output section flags. * testsuite/ld-scripts/sane1.t: Likewise. * testsuite/ld-elf/init-fini-arrays.s: Reference __init_array_start and __fini_array_start. Define __start et al. * testsuite/ld-elf/pr24511.d: New test. 2019-05-03 20:06:46 +08:00			`#source: init-fini-arrays.s`
