- Subject: [PATCH] ld-elf/ehdr_start: Pass --build-id to ld
- Authentication-results: sourceware.org; auth=none
ld-elf/ehdr_start fails with -z separate-code. Since there is no data
LOAD segment before code LOAD segment:
There are 2 program headers, starting at offset 64
Program Headers:
Type Offset VirtAddr PhysAddr FileSiz MemSiz Flg Align
LOAD 0x200000 0x0000000000600000 0x0000000000600000 0x000010 0x000010 R E 0x200000
LOAD 0x400000 0x0000000000800000 0x0000000000800000 0x000008 0x000008 R 0x200000
Section to Segment mapping:
Segment Sections...
00 .text
01 .rodata
the program header isn't included in any LOAD segment. As the result,
reference to __ehdr_start is resolved to zero. Pass --build-id to ld
to add a data LOAD segment before code LOAD segment to put the program
header in the data LOAD segment.

* testsuite/ld-elf/ehdr_start.d: Pass --build-id to ld.
