From 322ae2420d27fc96d0a8ab1167d7de33671048df Mon Sep 17 00:00:00 2001 From: Abseil Team Date: Tue, 12 Jan 2021 07:36:20 -0800 Subject: Export of internal Abseil changes -- 1609589925459c2c0b2a17912c0d65227f709db9 by Abseil Team : Clarify the "Potential Mutex deadlock" reason message. PiperOrigin-RevId: 351367862 -- 88bf28863db2c2d2d48767c3e4dfab6a48bdff79 by Abseil Team : Print CPU number is fault handler. This CL adds code to print CPU number inside the fault handler. This is only supported on Linux. The CPU number is also a hint only. There is no guarantee that it is indeed the CPU on which a fault happened. PiperOrigin-RevId: 351238373 -- 66a9c8e44b5744fec1ca0d7b8db7e1d50772d9a2 by Samuel Benzaquen : Add better error message for ODR violations of flags. PiperOrigin-RevId: 351197423 -- 6efd1efb341563148dd43255aaa4bf959dfd9554 by Chris Kennelly : Assume bitwise builtins are available on GCC. These are long-standing builtins but are not consistently detected by ABSL_HAVE_BUILTIN.
