Re: [4.1/4.0/3.4] fix pr19672 by tuning expansion of TRUTH_{AND,OR}_EXPR


> Paulo, please do apply this patch to 4.0 and 4.1.

Attached is a C testcase that would have triggered at -O0 (on the 3.4 branch).  
It relies on the transformation BIT_AND_EXPR -> TRUTH_AND_EXPR in the folder, 
as pointed out by Richard Kenner.

Can I install it on all open branches?
