Add checks for the NT_ARM_SVE section in a core file.
|
|
|
190f2a |
|
|
|
190f2a |
The NT_ARM_SVE section is documented here:
|
|
|
190f2a |
https://github.com/torvalds/linux/blob/master/Documentation/arm64/sve.txt
|
|
|
190f2a |
* A NT_ARM_SVE note will be added to each coredump for each thread of the
|
|
|
190f2a |
dumped process. The contents will be equivalent to the data that would have
|
|
|
190f2a |
been read if a PTRACE_GETREGSET of NT_ARM_SVE were executed for each thread
|
|
|
190f2a |
when the coredump was generated.
|

* elf.c (elfcore_grok_aarch_sve): New function.

(elfcore_grok_note): Check for Aarch64 SVE.

(elfcore_write_aarch_sve): New function.

190f2a |
