ld: Issue an error for GC on __patchable_function_entries section __patchable_function_entries section is generated by a compiler with -fpatchable-function-entry=XX. The assembly code looks like this: --- .text .globl _start .type _start, %function _start: .section __patchable_function_entries,"aw",%progbits .dc.a .LPFE1 .text .LPFE1: .byte 0 --- But --gc-sections will silently remove __patchable_function_entries section and generate corrupt result. This patch disallows garbage collection on __patchable_function_entries section without linked-to section. bfd/ PR ld/25490 * elflink.c (_bfd_elf_gc_mark_extra_sections): Issue an error for garbage collection on __patchable_function_entries section without linked-to section. ld/ PR ld/25490 * testsuite/ld-elf/pr25490-1.d: New file. * testsuite/ld-elf/pr25490-1.s: Likewise. 2020-02-07 11:37:54 +08:00			`#ld: --gc-sections -e _start`
