Rich Felker d16d7b1099 early stage ldso: remove symbolic references via error handling function ... while the error handling function should not be reached in stage 2 (assuming ldso itself was linked correctly), this was not statically determinate from the compiler's perspective, and in theory a compiler performing LTO could lift the TLS references (errno and other things) out of the printf-family functions called in a stage where TLS is not yet initialized. instead, perform the call via a static-storage, internal-linkage function pointer which will be set to a no-op function until the stage where the real error handling function should be reachable. inspired by commit 63c67053a3.		2022-07-19 19:00:53 -04:00
