This may have been a rhetorical question, but the middle-end's RTL
expanders are generating uses of uninitialized reg
This case looks like this:
typedef struct
{
unsigned char a : 2;
unsigned char b : 3;
unsigned char c : 1;
unsigned char d : 1;
unsigned char e : 1;
} a_struct;
foo (flags)
a_struct *flags;
{
return (flags->c != 0
|| flags->d != 1
|| flags->e != 1
