Add xchgq instruction to simplify encoding Signed-off-by: Paul Guyot <pguyot@kallisys.net>
Ensure all unaligned memory accesses are done byte by byte, fixing sigbus on arm Fix usage of __ORDER_LITTLE_ENDIAN__ which is likely to be always defined Add tests for unaligned reads and writes of integers in binaries Signed-off-by: Paul Guyot <pguyot@kallisys.net>
cmake `-DAVM_DISABLE_JIT=OFF` and autodetected JIT target impact what is compiled in some tests with `-DAVM_DISABLE_JIT` or `"-DAVM_JIT_TARGET_ARCH='${AVM_JIT_TARGET_ARCH}'"` passed to `erlc`. Signed-off-by: Paul Guyot <pguyot@kallisys.net> Signed-off-by: Paul Guyot <pguyot@kallisys.net>

Also enable parallel compilation (make -j3) and fix circular dependency when building precompiled archives Signed-off-by: Paul Guyot <pguyot@kallisys.net>
This follows what binutils as does. Unoptimized encoding wasn't wrong but if as is installed, the test would fail Signed-off-by: Paul Guyot <pguyot@kallisys.net>
Fix crash on armv6m when decoding types as term_from_int64 would fail Signed-off-by: Paul Guyot <pguyot@kallisys.net>
