* vdso_support: support DT_GNU_HASHFangrui Song2024-07-011-16/+43
| | | | | | | | | | | This library provides `LookupSymbol` and `LookupSymbolByAddress`. The latter needs `GetNumSymbols` support. An object file needs either .hash (DT_HASH) or .gnu.hash (DT_GNU_HASH). This patch adds DT_GNU_HASH support. Note: glibc has been supporting DT_GNU_HASH since 2006 and .hash has been quite obsoleted in the Linux communities. PiperOrigin-RevId: 648459622 Change-Id: I3aa1274cd4617990844258175715e3be2343afd2

PiperOrigin-RevId: 398534255 -- 9b99d074d39ad677cf92f99549d22bb73f504f8f by Saleem Abdulrasool <abdulras@google.com>: debugging: add support for non-glibc targets for debugging This relaxes the ELF mem_image handling and subsequently enables the VDSO support for non-glibc targets. The primary need for the restriction was the use of the `__GLIBC_PREREQ` macro. If it is undefined, assume that the glibc pre-requisite is unavailable. This allows building the debugging_internal target on musl targets.

PiperOrigin-RevId: 285220804 -- 68b015491f0dbf1ab547994673281abd1f34cd4b by Gennadiy Rozental <rogeeff@google.com>: This CL introduces following changes to the class FlagImpl: * We eliminate the CommandLineFlagLocks struct. 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.
