Implement _dl_catch_error, _dl_signal_error in libc.so [BZ #16628] This change moves the main implementation of _dl_catch_error, _dl_signal_error to libc.so, where TLS variables can be used directly. This removes a writable function pointer from the rtld_global variable. For use during initial relocation, minimal implementations of these functions are provided in ld.so. These are eventually interposed by the libc.so implementations. This is implemented by compiling elf/dl-error-skeleton.c twice, via elf/dl-error.c and elf/dl-error-minimal.c. As a side effect of this change, the static version of dl-error.c no longer includes support for the _dl_signal_cerror/_dl_receive_error mechanism because it is only used in ld.so. 2016-11-30 14:59:57 +00:00			`# The TLS-enabled version of these functions is interposed from libc.so.`

ld.so: Introduce struct dl_exception This commit separates allocating and raising exceptions. This simplifies catching and re-raising them because it is no longer necessary to make a temporary, on-stack copy of the exception message. 2017-08-10 11:40:22 +00:00			`ld.so: _dl_signal_exception`
