When -Wall is in use, the various avx512 compiler tests issue warnings which are detected as errors by autoconf. This notably crashes the ./configure step when an attempt of enforcing avx512 support is made. This patch adjusts the source code compiled and linked to not issue these warnings anymore.

Similarly to previous commit concerning avx512, this patch enables altivec support for powerpc hosts. Signed-off-by: Étienne Mollier <emollier@debian.org>
Similarly to avx512 and Altivec, this fixes detection of neon support by the compiler and linker. These are provided as separated commits, since the Neon patch shown afterwards, possibly specifically to Debian, that parasail fails to compile with errors in the SIMDe layer.

When -Wall is in use, the various compiler and linker tests related to SIMD extensions issue warnings about unused or unitialized variables detected as errors by autoconf. This notably crashes the ./configure step when an attempt of enforcing them with e.g. --enable-avx512=yes is made. This patch adjusts the source code compiled and linked to not issue these warnings anymore.
Affected SIMD extensions are avx512, altivec and neon. In the case of neon, but that's probably Debian specific since a different version of SIMDe is in use, getting the vectorization supported led to failure to build from source, so this patch is in a separate commit in case a revert were to be necessary.
In hope this helps,
Have a nice day, :)
Étienne.
