2014-07-28	fix powerpc dynamic linker thread-pointer-relative relocations	Rich Felker	-3/+3
	processing of R_PPC_TPREL32 was ignoring the addend provided by the RELA-style relocation and instead using the inline value as the addend. this presumably broke dynamic-linked access to initial TLS in cases where the addend was nonzero. (cherry picked from commit 94cf991bf4b18bb87a15a96e7b5e7d92fab787ba)
2013-09-15	support configurable page size on mips, powerpc and microblaze	Szabolcs Nagy	-1/+1
	PAGE_SIZE was hardcoded to 4096, which is historically what most systems use, but on several archs it is a kernel config parameter, user space can only know it at execution time from the aux vector. PAGE_SIZE and PAGESIZE are not defined on archs where page size is a runtime parameter, applications should use sysconf(_SC_PAGE_SIZE) to query it. Internally libc code defines PAGE_SIZE to libc.page_size, which is set to aux[AT_PAGESZ] in __init_libc and early in __dynlink as well. (Note that libc.page_size can be accessed without GOT, ie. before relocations are done) Some fpathconf settings are hardcoded to 4096, these should be actually queried from the filesystem using statfs.
2013-07-26	fix powerpc build breakage from dynamic linker path search changes	Rich Felker	-1/+1

2013-07-18	make the dynamic linker find its path file relative to its own location	Rich Felker	-1/+1
	prior to this change, using a non-default syslibdir was impractical on systems where the ordinary library paths contain musl-incompatible library files. the file containing search paths was always taken from /etc, which would either correspond to a system-wide musl installation, or fail to exist at all, resulting in searching of the default library path. the new search strategy is safe even for suid programs because the pathname used comes from the PT_INTERP header of the program being run, rather than any external input. as part of this change, I have also begun differentiating the names of arch variants that differ by endianness or floating point calling convention. the corresponding changes in the build system and and gcc wrapper script (to use an alternate dynamic linker name) for these configurations have not yet been made.
2012-11-16	dynamic linking support for powerpc	Rich Felker	-8/+27
	incomplete but at least partly working. requires all files to be compiled in the new "secure" plt model, not the old one that put plt code in the data segment. TLS is untested but may work. invoking the dynamic linker explicitly to load a program does not yet handle argv correctly.
2012-11-13	PPC port cleaned up, static linking works well now.	rofl0r	-0/+36
