* ld.so: Remove internal_function attribute from various functionsFlorian Weimer2017-08-131-4/+0
| | | | | These functions are invoked from other DSOs and should therefore use the standard calling convention.
* ld.so: Introduce struct dl_exceptionFlorian Weimer2017-08-101-67/+80
| | | | | | 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.

* Implement _dl_catch_error, _dl_signal_error in libc.so [BZ #16628]Florian Weimer2016-11-301-0/+230
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.
