[Bug middle-end/37135] [4.3/4.4 Regression] code size increase for bit-fields assignment



------- Comment #3 from etienne_lorrain at yahoo dot fr  2008-08-24 09:13 -------
 Moreover, if in the first test.c program, you declare variable "conf"
volatile,
the assembly generated contains 8 writes to "conf", and that memory location
is *read* 7 times. If "conf" does not point to memory but to memory mapped I/O
ports (maybe not readable), that is invalid code generated for valid input.
