* atomics: Disentangle 32bit and 64bit atomics configuration.Yann Ylavic2023-04-211-9/+20
| | | | | | | | | | | | | | | | Allow for --enable-nonportable-atomics=upto32bit to disable 64bit atomic builtins while still allowing for 32bit ones. yes/no still enables/disables both (if available in the first place..). By default (no --enable-nonportable-atomics setting), generic 64bit atomics are forced for 32bit CPUs/systems, until we figure out how to properly align apr_uint64_t (at least i[56]86 CPUs which could work with 64bit builtins actually don't if the data is not 64bit aligned, assuming the same for other 32bit CPUs is safer). git-svn-id: https://svn.apache.org/repos/asf/apr/apr/trunk@1909321 13f79535-47bb-0310-9956-ffa450edef68

* Fix crosscompiling detection in apr-1-configRuediger Pluem2023-03-101-0/+12
| | | | | | | | | | | | | | | | | | | Since r1872148 apr-1-config tries to detect if it runs in a crosscompile scenario. Fix the detection to correctly distinguish between crosscompiling and DESTDIR installations for packaging. * configure.in: Set APR_CROSS_COMPILING to 'no', 'yes' or 'maybe' based on possible --host and --build parameters given to configure to determine if configure was called for a crosscompiling scenario. This was inspired by how autoconf itself detects crosscompiling scenarios. * apr-config.in: Use the value from APR_CROSS_COMPILING to determine if we are in a crosscompiling scenario. Furthermore normalize the pathes we use for suffix matches by collapsing multiple consecutive '/' to one.

* configure: Test apr_uint64_t alignment for 64bit atomic builtins usability.Yann Ylavic2023-02-141-25/+43
| | | | | | | | | | | | | | | | | | | | | | | On some systems the __atomic builtins may be available only through libatomic or fall back to libatomic when the atomic operations are not issued on a suitably aligned address (64bit atomics on 8-byte aligned addresses only for instance). Modify the tests for HAVE_ATOMIC_BUILTINS64 and HAVE__ATOMIC_BUILTINS64 such that the address for the atomic operations is not aligned (unless 64bit ints always have the suitable alignment, i.e. mainly 64bit systems..). Also, use the __atomic_always_lock_free() builtin to fail the test when the compiler already knows about the alignment issue (falling back to libatomic, which we don't require/want). With this, 64bit builtins should be selected only for platforms that can natively handle atomics on any apr_uin64_t (since the APR has no dedicated 8-byte aligned 64bit type for now), while the generic/mutex implementation is used for others. git-svn-id: https://svn.apache.org/repos/asf/apr/apr/trunk@1907642 13f79535-47bb-0310-9956-ffa450edef68
