Francois Rousseau	a4754a9ae9	[snapshot][arm64] rename CPU context pstate to spsr ... * upon exception, the process state ("pstate") is stored in the saved process status register ("spsr") so the register we are manipulating is really just the SPSR * https://developer.arm.com/products/architecture/cpu-architecture/a-profile/docs/100878/latest/the-saved-process-status-register Change-Id: I9ce612c00b7a56a0f6d778d974ff9e0e5402ca5e Reviewed-on: https://chromium-review.googlesource.com/c/1312193 Reviewed-by: Joshua Peraza <jperaza@chromium.org> Commit-Queue: Francois Rousseau <frousseau@google.com>	2018-11-01 18:01:40 +00:00
Scott Graham	2ddfb4cd3c	fuchsia: CaptureContext for arm64 ... Copied from the _linux implementation, which looks close to what ucontext on Fuchsia is (though it will probably need to change). In arm64 debug, CaptureContext.CaptureContext requires slightly longer slop distance.

Scott Graham	e83103c805	fuchsia: Implement CaptureContext() for x64 ... Fuchsia enables safe-stack by default in the compiler. Disable it for the test function so that a candidate RSP value can be found by using the value of locals on the stack. (This also reduces the function prolog size sufficiently for the PC comparison to work, otherwise it required 75 bytes for the delta comparison.)
