2011-06-27cleanup shared library build system to be more $HOME-local-install friendlyRich Felker-1/+4
the path for the dynamic linker is now configurable, and failure to install the symlink for it will not stop the build.
2011-06-23adapt build/install/gcc-wrapper systems for dynamic linking supportRich Felker-2/+2
2011-05-07overhaul implementation-internal signal protectionsRich Felker-1/+1
the new approach relies on the fact that the only ways to create sigset_t objects without invoking UB are to use the sig*set() functions, or from the masks returned by sigprocmask, sigaction, etc. or in the ucontext_t argument to a signal handler. thus, as long as sigfillset and sigaddset avoid adding the "protected" signals, there is no way the application will ever obtain a sigset_t including these bits, and thus no need to add the overhead of checking/clearing them when sigprocmask or sigaction is called. note that the old code actually *failed* to remove the bits from sa_mask when sigaction was called. the new implementations are also significantly smaller, simpler, and faster due to ignoring the useless "GNU HURD signals" 65-1024, which are not used and, if there's any sanity in the world, never will be used.
