Remove ia64-linux-gnu

2024-01-08T20:09:36Z

Linux 6.7 removed ia64 from the official tree [1], following the general principle that a glibc port needs upstream support for the architecture in all the components it depends on (binutils, GCC, and the Linux kernel). Apart from the removal of sysdeps/ia64 and sysdeps/unix/sysv/linux/ia64, there are updates to various comments referencing ia64 for which removal of those references seemed appropriate. The configuration is removed from README and build-many-glibcs.py. The CONTRIBUTED-BY, elf/elf.h, manual/contrib.texi (the porting mention), *.po files, config.guess, and longlong.h are not changed. For Linux it allows cleanup some clone2 support on multiple files. The following bug can be closed as WONTFIX: BZ 22634 [2], BZ 14250 [3], BZ 21634 [4], BZ 10163 [5], BZ 16401 [6], and BZ 11585 [7].

Assume only FLAG_ELF_LIBC6 suport

2022-08-04T12:09:48Z

The older libc versions are obsolete for over twenty years now. This patch removes the special flags for libc5 and libc4 and assumes that all libraries cached are libc6 compatible and use FLAG_ELF_LIBC6. Checked with a build for all affected architectures.

elf: Fix compile error with -Werror and -DNDEBUG

Using -Werror and -DNDEBUG at the same time will trigger the following compiler error: cache.c: In function 'save_cache': cache.c:758:15: error: unused variable 'old_offset' [-Werror=unused-variable] 758 | off64_t old_offset = lseek64 (fd, extension_offset, SEEK_SET); | ^~~~~~~~~~ -DNDEBUG disables the assertion, making old_offset unused.
