Public bug reported:
I just debugged a problem I had with linux-user for qemu-sparc32plus.
Turns out that sparc32plus is defined as a 64bit target with
TARGET_ABI32 set. This correctly leads to abi_ulong (and others) being
defined as uint32_t. However most of the code (in syscall.c) uses tswapl
for these values, which swaps the endianess of a target long (which is
64bit). This doesn't match the uin32_t abi_ulongs and fails!
So it appears to me like one would need to define something like an
aswapl which swaps abi_ulongs and replace most of the tswapls there...
