*	Consolidate Linux getdents{64} implementation	Adhemerval Zanella	2018-04-19	1	-4/+0
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	This patch consolidates Linux getdents{64} implementation on just the default sysdeps/unix/sysv/linux/getdents{64}{_r}.c ones. Although this symbol is used only internally, the non-LFS version still need to be build due the non-LFS getdirentries which requires its semantic. The non-LFS default implementation now uses the wordsize-32 as base which uses getdents64 syscall plus adjustment for overflow (it allows to use the same code for architectures that does not support non-LFS getdents syscall). It has two main differences to wordsize-32 one: - DIRENT_SET_DP_INO is added to handle alpha requirement to zero the padding. - alloca is removed by allocating a bounded temporary buffer (it increases stack usage by roughly 276 bytes). The default implementation handle the Linux requirements: * getdents is only built for _DIRENT_MATCHES_DIRENT64 being 0. * getdents64 is always built and aliased to getdents for ABIs that define _DIRENT_MATCHES_DIRENT64 to 1. * A compat symbol is added for getdents64 for ABI that used to export the old non-LFS version. Checked on aarch64-linux-gnu, x86_64-linux-gnu, i686-linux-gnu, sparcv9-linux-gnu, sparc64-linux-gnu, powerpc-linux-gnu, and powerpc64le-linux-gnu. * sysdeps/unix/sysv/linux/alpha/getdents.c: Add comments with alpha requirements.
