2018-04-27	Remove tilegx port.	Joseph Myers	1	-21/+0
	Since tile support has been removed from the Linux kernel for 4.17, this patch removes the (unmaintained) port to tilegx from glibc (the tilepro support having been previously removed). This reflects the general principle that a glibc port needs upstream support for the architecture in all the components it build-depends on (so binutils, GCC and the Linux kernel, for the normal case of a port supporting the Linux kernel but no other OS), in order to be maintainable. Apart from removal of sysdeps/tile and sysdeps/unix/sysv/linux/tile, there are updates to various comments referencing tile for which removal of those references seemed appropriate. The configuration is removed from README and from build-many-glibcs.py. contrib.texi keeps mention of removed contributions, but I updated Chris Metcalf's entry to reflect that he also contributed the non-removed support for the generic Linux kernel syscall interface. __ASSUME_FADVISE64_64_NO_ALIGN support is removed, as it was only used by tile. * sysdeps/tile: Remove. * sysdeps/unix/sysv/linux/tile: Likewise. * README (tilegx--linux-gnu): Remove from list of supported configurations. manual/contrib.texi (Contributors): Mention Chris Metcalf's contribution of support for generic Linux kernel syscall interface. * scripts/build-many-glibcs.py (Context.add_all_configs): Remove tilegx configurations.

2018-01-25	LIBC_SLIBDIR_RTLDDIR: substitute arguments in single quotes	Andreas Schwab	1	-2/+2
	The arguments of the LIBC_SLIBDIR_RTLDDIR macro are used both in unquoted and single quoted context, so that neither shell nor makefile variable references work. Consistently put them in single quotes so that they can refer to makefile variables.
2017-12-20	Simplify tilegx sysdeps folder	Adhemerval Zanella	1	-0/+21
	With tilepro support removal we can now simplify internal tile support by moving the directory structure to avoid the unnecessary directory levels in tile/tilegx both on generic and linux folders. Checked with a build for tilegx-linux-gnu and tilegx-linux-gnu-32 with and without the patch, there is no difference in generated binary with a dissassemble. * stdlib/bug-getcontext.c (do_test): Remove tilepro mention in comment. * sysdeps/tile/preconfigure: Remove tilegx folder. * sysdeps/tile/tilegx/Implies: Move definitions to ... * sysdeps/tile/Implies: ... here. * sysdeps/tile/tilegx/Makefile: Move rules to ... * sysdeps/tile/Makefile: ... here. * sysdeps/tile/tilegx/atomic-machine.h: Move definitions to ... * sysdeps/tile/atomic-machine.h: ... here.

2014-04-30	Increase minimum Linux kernel version to 2.6.32.	Joseph Myers	1	-4/+0
	This patch increases the minimum Linux kernel version for glibc to 2.6.32, as discussed in the thread starting at <https://sourceware.org/ml/libc-alpha/2014-01/msg00511.html>. This patch just does the minimal change to arch_minimum_kernel settings (and LIBC_LINUX_VERSION, which determines the minimum kernel headers version, as it doesn't make sense for that to be older than the minimum kernel that can be used at runtime). Followups would be expected to do, roughly and not necessarily precisely in this order: * Remove __LINUX_KERNEL_VERSION checks in kernel-features.h files where those checks are always true / always false for kernels 2.6.32 and above. * Otherwise simplify/improve conditionals in those files (for example, where defining once in the main file then undefining in architecture-specific files makes things clearer than having lots of separate definitions of the same macro), possibly fixing in the process cases where a macro should optimally have been defined for a given architecture but wasn't. (In the review in preparation for this version increase I checked what the right conditions should be for all macros in the main kernel-features.h whose definitions there would have been affected by the increase - but I only fixed that subset of the issues found where --enable-kernel=2.6.32 would have caused a kernel feature to be wrongly assumed to be present, not any cases where a feature is not assumed but could be assumed.) * Remove conditionals on __ASSUME_* where they can now be taken to be always-true, and the definitions when the macros are only used in Linux-specific files. * Split more architectures out of the main kernel-features.h (like ex-ports architectures), once various of the architecture conditionals there have been eliminated so the new architecture-specific files are no larger than actually necessary. Tested x86_64. 2014-03-27 Joseph Myers <joseph@codesourcery.com> [BZ #9894] * sysdeps/unix/sysv/linux/configure.ac (LIBC_LINUX_VERSION): Change to 2.6.32. (arch_minimum_kernel): Change all 2.6.16 settings to 2.6.32. * sysdeps/unix/sysv/linux/configure: Regenerated. * sysdeps/unix/sysv/linux/microblaze/configure.ac: Remove file. * sysdeps/unix/sysv/linux/microblaze/configure: Likewise. * sysdeps/unix/sysv/linux/tile/configure.ac: Likewise. * sysdeps/unix/sysv/linux/tile/configure: Likewise. * README: Update reference to required Linux kernel version. * manual/install.texi (Linux): Update reference to required Linux kernel headers version. * INSTALL: Regenerated.
2014-02-10	Move tilegx, tilepro, and linux-generic from ports to libc.	Chris Metcalf	1	-0/+4
	I've moved the TILE-Gx and TILEPro ports to the main sysdeps hierarchy, along with the linux-generic ports infrastructure. Beyond the README update, the move was just git mv ports/sysdeps/tile sysdeps/tile git mv ports/sysdeps/unix/sysv/linux/tile \ sysdeps/unix/sysv/linux/tile git mv ports/sysdeps/unix/sysv/linux/generic \ sysdeps/unix/sysv/linux/generic I updated the relevant ChangeLogs along the lines of the ARM move in commit c6bfe5c4d75 and tested the 64-bit tilegx build to confirm that there were no changes in "objdump -dr" output in the shared objects.
