Commit Message

Adhemerval Zanella Netto June 8, 2017, 9:13 p.m. UTC
This patch consolidates the glob implementation.  The main changes are:

  * Remove specific defines required for multiple compilation in same
    unit (GLOB_ONLY_P, NO_GLOB_PATTERN_P and GLOB_COMPAT_BUILD).  To allow
    using the same code to build compat version on Linux, extra units are
    used instead (oldglob.c).

  * Both globfree and GNU extension glob_pattern_p are now on their files.
    This simplifies the creation of compat symbol when required.

  * Also similar to glob/glob64, a new globfree64 is file is added with an
    empty implementatio as default.

  * On Linux all implementation now uses a default one with the exception
    of alpha (which requires a specific versioning) and s390-32 (which
    different than other 32 bits with support for v2.1 symbol does not
    add a compat symbol).

  * Move i386 olddirent.h header to Linux default directory, since it is
    the only header with this name and it is shared among different
    architectures (and used on compat glob symbol).

Checked on x86_64-linux-gnu and i686-linux-gnu.

	* posix/Makefile (routines): Add globfree, globfree64, and
	glob_pattern_p.
	* posix/glob.c: Remove GLOB_ONLY_P, GLOB_COMPAT_BUILD, and
	NO_GLOB_PATTERN_P define usage.
