[PATCH 0/4] qemu/bswap: Let cpu_to_endian() functions handle constant expressions

[Philippe Mathieu-Daudé]

Stefan Hajnoczi suggested we can use __builtin_constant_p()
in the cpu_to_ENDIAN()/ENDIAN_to_cpu() functions to check if
expression is constant, and if so use the const_ENDIAN() macros.

This series modifies cpu_to_ENDIAN() to use const_ENDIAN() when
possible.

Philippe Mathieu-Daudé (4):
  qemu/bswap: Move const_le() definitions around
  qemu/bswap: add const_be16() and const_be32()
  qemu/bswap: Add const_le64() and const_be64()
  qemu/bswap: Let cpu_to_endian() functions handle constant expressions
