c9ec0e8945
On MIPS o32, n32 and n64 platforms, PID information was not
correctly propagated from core dump file to internal GDB
structures. This patch fixes that behavior.
A correct PID is needed by `libthread_db' library supplied with
glibc repository revisions before commit c579f48edba8 ("Remove
cached PID/TID in clone") or released versions before 2.25 for
GDB to fetch value of TLS variable from core file.
bfd/ChangeLog:
* elf32-mips.c (elf32_mips_grok_psinfo): Extract core->pid.
* elf64-mips.c (elf64_mips_grok_psinfo): Likewise.
* elfn32-mips.c (elf32_mips_grok_psinfo): Likewise.
