# exports. These tests therefore run on emulated targets, reusing the RISC-V

# These tests are 32-bit only for now, and the reason is a gap in the layer
# rather than a choice about coverage.
#
# The layer passes a message by putting the address of a private buffer into the
# queue. ULONG is 32 bits on every ThreadX port, including the 64-bit ones, so
# on a 64-bit target that address only fits if TX_64_BIT is defined: the layer
# then splits it across two message words and sizes the message accordingly.
# Without it, px_mq_send.c truncates the pointer to 32 bits and px_mq_receive.c
# casts the truncated value back, which the compiler reports only as a warning.
#
# Defining TX_64_BIT is not a way out either: tx_api.h then uses the extension
# pointer macros, which need tx_thread_extension_ptr in the thread control
# block, and no 64-bit port outside ports_smp and ports/linux declares it.
# Closing that gap belongs with the layer, not with its tests.
