    • fold-const: Don't access bit fields with too big mode (PR71310) · 95c18dd0 
      Currently, optimize_bit_field_compare reads the bitfield in word_mode
if it can.  If the bit field is normally accessed in a smaller mode,
this might be a violation of the memory model, although the "extra"
part of the read is not used.  But also, previous stores to the bit
field will have been done in the smaller mode, and then bigger loads
from it cause a LHS problem.


	PR middle-end/71310
	* fold-const.c (optimize_bit_field_compare): Don't try to use
	word_mode unconditionally for reading the bit field, look at
	DECL_BIT_FIELD_REPRESENTATIVE instead.

	PR middle-end/71310
	* gcc.target/powerpc/pr71310.c: New testcase.
