* Only check if the frame pointer is inside a signal stack with known boundsGravatar Abseil Team2024-03-28
| | | | | | | | This function previously returned true whenever the signal stack had unknown bounds, that is obviously incorrect. PiperOrigin-RevId: 620084964 Change-Id: I3821730b45773300569b9cbdb7e72442ed109d04

* Properly handle signal stacks and frame-size calculationsGravatar Abseil Team2023-11-07
| | | | | | | | | | | | | We can determine the signal stack, so use that information to make better decisions about when to calculate the frame size and when not to. This fixes a several tests where the memory layout had the signal stack and main stack in position that confused some of the greater-than/less-than comparisons. Also cleanup certain types to avoid more casting than necessary. PiperOrigin-RevId: 580221819 Change-Id: I0365b03e7893741603dc66e6d36a069d0b7f5404
* With sufficiently high-levels of optimization, this functionGravatar Abseil Team2023-10-04
| | | | | | | | | and those that call it can be inlined sufficiently far to mess up high-level skip-counts. But this function assumes it is the bottommost frame, as in the comment below. PiperOrigin-RevId: 570790048 Change-Id: I4d354f9e79e13aaa6a8a62a9e0870fbeac075de6

* The current aarch64 large-stack frame error handling is unsophisticated,Gravatar Abseil Team2023-06-15
| | | | | | | | | | | which makes it give up in certain situations where the x86 handler works fine This change adopts x86's more sophisticated stack-bounds-checking method for aarch64, and enables the HugeStack test to pass on aarch64.

* Fix unwinding through nested signal frames on aarch64.Gravatar Abseil Team2023-06-09
| | | | | | | | | | | | | | | This fixes an endless loop in the absl Arm stack unwinder where encountering a second signal return trampoline (as one has in nested signal frames), would restart unwinding at the outermost signal, resulting in an endless loop. This does not change any behavior in the non-nested signal case, so I believe it is safe for any stack that hasn't encountered this bug already. I would love to test this beyond the absl unwinding test cases and the fingerprint_test included here, but I'm at a loss for other test cases.

* Fix frame pointer alignment check.Gravatar Abseil Team2022-07-26
| | | | | | | The frame pointer sanity check in NextStackFrame() was more restrictive than it is necessary. The frame pointer is used to load the saved link-register and the address for the next stack frame. So it only needs to be 8-byte aligned. The aarch64 ABI does not specify an alignment requirement for the frame point. PiperOrigin-RevId: 463368519 Change-Id: I473e05181603288f14734fe29013900c7505e201

Instead callback guard and callback function are combined into a single CallbackData struct, while primary data lock is stored separately. * CallbackData member of class FlagImpl is initially set to be nullptr and is only allocated and initialized when a flag's callback is being set. For most flags we do not pay for the extra space and extra absl::Mutex now. * Primary data guard is stored in data_guard_ data member. This is a properly aligned character buffer of necessary size. During initialization of the flag we construct absl::Mutex in this space using placement new call. * We now avoid extra value copy after successful attempt to parse value out of string. Instead we swap flag's current value with tentative value we just produced.
