	[Bug ld/10515] New: Linker corrupts the paddr and vaddr in program header by Bugzilla from sourceware-bugzilla@sourceware.org :: Rate this Message: Reply to Author \| View Threaded \| Show Only this Message I am attaching a sample program compiled using two different linker scripts producing two different ELF files. The two linker scripts are test_good.lds test_faulty.lds. There is a trivial difference between two files. In test_good.lds, 'ro_data' PHDRS entry is in first place. In test_faulty.lds, 'ro_data' PHDRS entry is in second place. The two elf files produced are test_good.elf, test_faulty.elf. 'objdump -p' of both the files is shown below. [sample]$ objdump -p test_good.elf test_good.elf: file format elf32-big Program Header: LOAD off 0x00000000 vaddr 0x0c000000 paddr 0x00100000 align 216 filesz 0x00100000 memsz 0x00100000 flags r-x LOAD off 0x00100000 vaddr 0x00200000 paddr 0x00200000 align 216 filesz 0x00100000 memsz 0x00100000 flags rw- 400000 LOAD off 0x00200000 vaddr 0x08000000 paddr 0x08000000 align 216 filesz 0x00000000 memsz 0x04000000 flags rw- 400000 LOAD off 0x00200000 vaddr 0x00300000 paddr 0x00300000 align 216 filesz 0x00010000 memsz 0x00070000 flags rw- 0x8 off 0x00000000 vaddr 0x01000000 paddr 0x01000000 align 20 filesz 0x00000000 memsz 0x07000000 flags rw- 0x8 off 0x00000000 vaddr 0x2c000000 paddr 0x2c000000 align 20 filesz 0x00000000 memsz 0x04000000 flags rw- 400000 0x8 off 0x00000000 vaddr 0x10000000 paddr 0x10000000 align 20 filesz 0x00000000 memsz 0x04000000 flags rw- a00000 0x8 off 0x00000000 vaddr 0x28000000 paddr 0x28000000 align 20 filesz 0x00000000 memsz 0x04000000 flags rw- 400000 [sample]$ objdump -p test_faulty.elf test_faulty.elf: file format elf32-big Program Header: LOAD off 0x00010000 vaddr 0x00200000 paddr 0x00200000 align 216 filesz 0x00100000 memsz 0x00100000 flags rw- 400000 LOAD off 0x00000000 vaddr 0x0bf00000 paddr 0x00000000 align 216 filesz 0x00200000 memsz 0x00200000 flags r-x LOAD off 0x00200000 vaddr 0x08000000 paddr 0x08000000 align 216 filesz 0x00000000 memsz 0x04000000 flags rw- 400000 LOAD off 0x00200000 vaddr 0x00300000 paddr 0x00300000 align 216 filesz 0x00010000 memsz 0x00070000 flags rw- 0x8 off 0x00000000 vaddr 0x01000000 paddr 0x01000000 align 20 filesz 0x00000000 memsz 0x07000000 flags rw- 0x8 off 0x00000000 vaddr 0x2c000000 paddr 0x2c000000 align 20 filesz 0x00000000 memsz 0x04000000 flags rw- 400000 0x8 off 0x00000000 vaddr 0x10000000 paddr 0x10000000 align 20 filesz 0x00000000 memsz 0x04000000 flags rw- a00000 0x8 off 0x00000000 vaddr 0x28000000 paddr 0x28000000 align 20 filesz 0x00000000 memsz 0x04000000 flags rw- 400000 Check that in 'objdump -p test_faulty.elf ' output, the second segement entry contains paddr as 0 and vaddr as 0x0bf00000.
