2025-05-15powerpc: Remove check for -mabi=ibmlongdoubleAndreas Schwab1-42/+1
The -mabi=ibmlongdouble option has been added in gcc 4.2, thus can be assumed to always exist.
2025-04-02sysdeps: powerpc: restore -mlong-double-128 checkSam James1-0/+83
We mistakenly dropped the check in 27b96e069aad17cefea9437542180bff448ac3a0; there's some other checks which we *can* drop, but let's worry about that later. Fixes the build on ppc64le where GCC is configured with --with-long-double-format=ieee. Reviewed-by: Andreas Schwab <schwab@suse.de>

Need to work around bugs in older versions of GCC. 2. Can't use the new features in newer versions of GCC, which may be required for new features, like _Float16 which requires GCC 12.1 or above, in glibc, The main benefit of supporting older versions of GCC is easier backport of bug fixes to the older releases of glibc, which can be mitigated by avoiding incompatible features in newer versions of GCC for critical bug fixes. Require GCC 12.1 or newer to build. Remove GCC version check for PowerPC and s390x. TEST_CC and TEST_CXX can be used to test the glibc build with the older versions of GCC. For glibc developers who are using Linux OSes which don't come with GCC 12.1 or newer, they should build and install GCC 12.1 or newer to work on glibc. This fixes BZ #32539. Signed-off-by: H.J.

2023-07-17configure: Use autoconf 2.71Siddhesh Poyarekar1-27/+32
Bump autoconf requirement to 2.71 to allow regenerating configure on more recent distributions. autoconf 2.71 has been in Fedora since F36 and is the current version in Debian stable (bookworm). It appears to be current in Gentoo as well. All sysdeps configure and preconfigure scripts have also been regenerated; all changes are trivial transformations that do not affect functionality.

2021-10-25configure: Don't check LD -v --help for LIBC_LINKER_FEATUREFangrui Song1-11/+8
When LIBC_LINKER_FEATURE is used to check a linker option with the equal sign, it will likely fail because the LD -v --help output may look like `-z lam-report=[none|warning|error]` while the needle is something like `-z lam-report=warning`. The LD -v --help filter doesn't save much time, so just remove it.

2014-06-24Move architecture cases out of sysdeps/unix/sysv/linux/configure.ac.Joseph Myers1-0/+2
Continuing the process of making non-ex-ports architectures follow the preferred sysdeps practices followed by ex-ports architectures - that is, putting things in architecture-specific sysdeps files rather than having architecture-specific cases in architecture-independent files - this patch moves architecture cases out of sysdeps/unix/sysv/linux/configure.ac into (new or existing) configure fragments for each architecture. (In the case of the arch_minimum_kernel setting for x32, sysdeps/unix/sysv/linux/x86_64/x32/configure already has such a setting so the setting in sysdeps/unix/sysv/linux/configure.ac was a duplicate that could just be removed - though I haven't tested for x32.) Tested for x86_64 and x86 that the patch causes no changes to the installed shared libraries or ldd (or any part of the installation except for the parts that always change because the files contain timestamps - nscd and static libraries). * sysdeps/unix/sysv/linux/configure.ac: Remove cases for individual architectures. * sysdeps/unix/sysv/linux/configure: Regenerated. * sysdeps/unix/sysv/linux/i386/configure.ac: New file. * sysdeps/unix/sysv/linux/i386/configure: New generated file. * sysdeps/unix/sysv/linux/powerpc/configure.ac (ldd_rewrite_script): Define variable. * sysdeps/unix/sysv/linux/powerpc/configure: Regenerated. * sysdeps/unix/sysv/linux/powerpc/powerpc32/configure.ac: New file. * sysdeps/unix/sysv/linux/powerpc/powerpc32/configure: New generated file. * sysdeps/unix/sysv/linux/s390/configure.ac: New file. * sysdeps/unix/sysv/linux/s390/configure: New generated file. * sysdeps/unix/sysv/linux/sh/configure.ac: New file. * sysdeps/unix/sysv/linux/sh/configure: New generated file. * sysdeps/unix/sysv/linux/sparc/configure.ac: New file. * sysdeps/unix/sysv/linux/sparc/configure: New generated file. * sysdeps/unix/sysv/linux/x86_64/configure.ac: New file. * sysdeps/unix/sysv/linux/x86_64/configure: New generated file.
