* ldlang.c (lang_output_section_statement_lookup): Add function comment. Make "name" non-const. Ensure duplicate entries use the same string, allowing simple comparison in hash bucket loop. Tweak constraint check. (next_matching_output_section_statement): New function. * ldlang.h (lang_output_section_statement_lookup): Update. (next_matching_output_section_statement): Declare. * emultempl/elf32.em (gld${EMULATION_NAME}_place_orphan): Don't combine orphan sections when input sections flags differ in alloc or load. * emultempl/pe.em: Formatting throughout. (gld${EMULATION_NAME}_place_orphan): As for elf32.em. * emultempl/pep.em: Formatting throughout. (gld${EMULATION_NAME}_place_orphan): As for elf32.em. ld/testsuite/ * ld-elf/orphan3.d, * ld-elf/orphan3a.s, * ld-elf/orphan3b.s, * ld-elf/orphan3c.s, * ld-elf/orphan3d.s, * ld-elf/orphan3e.s, * ld-elf/orphan3f.s: New test. * ld-pe/orphan.d, * ld-pe/orphana.s, * ld-pe/orphanb.s, * ld-pe/orphand.s, * ld-pe/orphane.s: New test. * ld-pe/direct.exp: Use is_pecoff_format. * ld-pe/longsecn.exp: Delete. * ld-pe/pe.exp: Run new test and longsecn tests.
