* - Use runtime pagesize (Jeremy Kerr)Bernhard Reutner-Fischer2008-12-031-0/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some powerpc machines can support 64k pages, enabled by the CONFIG_64K_PAGES option in linux. However, the uClibc dynamic loader won't currently work on these machines, as it uses hard-coded values (PAGE_ALIGN, ADDR_ALIGN and OFFS_ALIGN) in the ldso architecture-specific headers. When running on a kernel with 64k pages, ld.so tries to mmap with 4k-aligned addresses, rather than 64k, so mmap fails with -EINVAL. When booting a 64k machine with a uClibc dynamic linker, init fails with: /init:500: can't map '/lib/libc.so.0' /init:500: can't map '/lib/libc.so.0' /init:500: can't map '/lib/libc.so.0' /init: can't load library 'libc.so.0' Kernel panic - not syncing: Attempted to kill init! This change allows ld.so determine these alignment masks at runtime, rather than compile-time. Since we have the _dl_pagesize variable available, we can use that to generate the appropriate masks. Since almost all of the architectures can use the common definitions for the _ALIGN macros, we can consolidate them all in ldso.h, and override in the sysdep headers where necessary (ie, mips). This allows me to start a uClibc-based root fs on a 64k machine. Signed-off-by: Jeremy Kerr <jk at ozlabs org>
* - fix the macros rather than the callees as rightfully noted by bernds (duh!)Bernhard Reutner-Fischer2008-05-301-3/+3

* Some more Blackfin/FDPIC ldso merging work. Include dl-inlines.h when itBernd Schmidt2008-01-081-0/+4

* Blackfin FD-PIC patches 5/6.Bernd Schmidt2007-12-031-1/+9
| | | | | | | A couple more target macros for ld.so to deal with FD-PIC support. We need special code to compute the initial got and dpnt, and we need to pass extra arguments to _dl_get_ready_to_run.
* Blackfin FD-PIC patch 1/6.Bernd Schmidt2007-12-031-1/+2
| | | | | | | Add a new function _dl_free. In _dl_malloc, ensure we always get back a full page from mmap. Reset _dl_malloc_function and _dl_free_function when libdl is initialized.
* Define _dl_assert in libdl only if __DOASSERTS__ is defined. Thanks to Peter ↵Carmelo Amoroso2007-11-091-7/+16
