Hi all,
I have found a problem with assembler code generation in network stack
on ARM processor (aligment fault).
I am using:
arm-rtems5-gcc (GCC) 7.2.0 20170814 (RTEMS 5, RSB
a6d011e028a0776cedf0823940eb882e917a44e5, Newlib 2.5.0.20170922)
The compiler generates invalid instruction 'ldmia' here
(https://git.rtems.org/rtems/tree/cpukit/libnetworking/netinet/udp_usrreq.c#n160).
The instruction does not support unaligned accesses.
Also i have found the bug fix in FreeBSD repository
(https://github.com/freebsd/freebsd/commit/6cc0e8d2a0b583db5707f811d4ebfbe1ad05e628)
this is a three year old commit. Which libbsd version do you use? This
fix is included in the libbsd 4.11 and master branch.
