Siddhesh Poyarekar	c6cb8783b5	configure: Use autoconf 2.71 ... 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.

Fangrui Song	098a657fe4	elf: Replace PI_STATIC_AND_HIDDEN with opposite HIDDEN_VAR_NEEDS_DYNAMIC_RELOC ... PI_STATIC_AND_HIDDEN indicates whether accesses to internal linkage variables and hidden visibility variables in a shared object (ld.so) need dynamic relocations (usually R_*_RELATIVE). PI (position independent) in the macro name is a misnomer: a code sequence using GOT is typically position-independent as well, but using dynamic relocations does not meet the requirement. Not defining PI_STATIC_AND_HIDDEN is legacy and we expect that all new ports will define PI_STATIC_AND_HIDDEN. Current ports defining PI_STATIC_AND_HIDDEN are more than the opposite. Change the configure default. No functional change. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>	2022-04-26 09:26:22 -07:00
Stafford Horne	3f35e7d193	or1k: Define PI_STATIC_AND_HIDDEN ... PI_STATIC_AND_HIDDEN means that references to static functions, data and symbols with hidden visibility do not need any run-time relocations after the final link, with the build flags used by glibc. OpenRISC follows this so enabled PI_STATIC_AND_HIDDEN by adding configure.ac and generating configure. Suggested-by: Florian Weimer <fweimer@redhat.com>	2022-02-02 20:05:12 +09:00
