* amd64-linux-nat.c: Support new linux_elfcore_write_prpsinfo,
|
||
linux_elfcore_write_prstatus, linux_elfcore_write_prfpreg.
|
||
(i386_linux_gregset32_reg_offset): New mapping for i386 on amd64.
|
||
* gcore.c (gcore_create_callback): Comment vdso Linux kernel bug.
|
||
* configure.ac: Check for <sys/user32.h>, <sys/procfs32.h>.
|
||
* configure, config.in: Regenerated.
|
||
* gdb_user32.h, gdb_procfs32.h: Define 32-bit core files even for
|
||
64-bit gdb, provide fallbacks for <sys/user32.h> and <sys/procfs32.h>.
|
||
* linux-nat.c: Virtualize `elfcore_*' by (*`linux_elfcore_*').
|
||
(linux_nat_do_thread_registers): Likewise.
