Re: pr39339 - invalid testcase or SRA bug?
Yes, if i change the structure to bring the 3 1-bit members forward, to
avoid padding, the testcase does pass.
Thanks to both of you for your help.

Since r144598, pr39339.c has been failing on picochip. On investigation,
it looks to me that the testcase is illegal.
Relevant source code:
unsigned int c;
unsigned int columns : 4;
unsigned int fore : 9;
unsigned int back : 9;
As the testcase fails with buggy (pre r144598) gcc and succeeds after even
unsigned int fore : 12;
unsigned int back : 6;
instead of :9, :9, I think we could change it (does it succeed on picochip
then)? Or move to gcc.dg/torture/ and run only on int32plus targets.
Or add if (sizeof (int) != 4 || sizeof (struct D) != 4) return 0
to the beginning of main.
