Expand description
An old (breakpad-style) aarch64 (arm64) CPU context.
This is a breakpad extension, but contrary to what the name might suggest, it isn’t completely out of service. I believe all non-windows platforms still prefer emitting this format to avoid needless churn.
Semantically this type agrees with the “new” CONTEXT_ARM64 and can
generally be handled with all the same logic. i.e. the general purpose
iregs
are the same. It’s just that the other fields are shuffled around.
As I understand it, this is basically an artifact of breakpad getting to arm64 “first” (Android would be first in line for it!) and picking a definition they thought was reasonable. Thankfully they picked an “out of the way” context id so that when Microsoft came along and picked their own definition, there wouldn’t be a conflict.
Note that we have inlined the fields of the “float save” struct from breakpad’s definition to be more uniform with CONTEXT_ARM64.
NOTE: if you ever decide to try to make this repr(C) and get really clever, this type is actually non-trivially repr(packed(4)) in the headers!
