* Makerules (build-shlib): Add $(extra-B-$(@F:lib%.so=%).so).
|
||||
* configure.in: Test for -z initfirst linker option.

||||
* config.make.in: Add have-z-initfirst.
|
||||
* elf/dl-init.c (_dl_init): Split out actual initialization code in

||||
new function call_init. If _dl_initfirst is non-NULL initialize first.

|
||||
remember object in _dl_initfirst.
|
||||
* elf/soinit.c: Remove special support for calling
|
||||
__pthread_initialize_minimal.
|
||||
|
||||
* conform/conformtest.pl: Add missing $prepend in type test.
