Bug #: 14068
Summary: Split top-level config.h.in into machine dependent and
machine independent pieces.
Product: glibc
Version: unspecified
Status: NEW
Severity: normal
Priority: P2
Component: libc
AssignedTo: carlos_odonell@mentor.com
ReportedBy: carlos_odonell@mentor.com
CC: drepper.fsp@gmail.com
Classification: Unclassified
At present the glibc sources have one top-level config.h.in file.
The config.h.in file contains several definitions for x86, x86_64, Power, and
ARM.
Logically speaking this file should contain only machine independent
definitions.
Instead each machine should have a config.h.in fragment that is aggregated
together with the top-level config.h.in to produce a final config.h.
At present each machine needs to add defines to the top-level config.h.in.

And SPARC (HAVE_AS_VIS3_SUPPORT, HAVE_GCC_GOTDATA). And Linux-specific
(__LINUX_KERNEL_VERSION). And some Mach-specific defines
(HAVE_HOST_PAGE_SIZE, HAVE_I386_IO_PERM_MODIFY, HAVE_I386_SET_GDT,
HAVE_MIG_RETCODE - the last of these isn't used anywhere and for the
middle two, only used in sysdeps/mach/hurd/i386/, I'd have thought glibc
could just require the preferred answer to the test rather than
conditioning things). And one of the Power defines (BROKEN_PPC_ASM_CR0)
actually has its configure test directly in the toplevel configure.in.

As always we should look to see if any of these checks are still valid.
For example we could use `-ansi' instead of `-undef' in the implicit rule to
allow HAVE_ARM_PCS_VFP to go away and become simply %ifdef __ARM_PCS_VFP in
ARM's shlib-versions.
