Summary: 2006-01-23-InitializedBitField.c uses over-width bools
Product: Test Suite
Version: trunk
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P2
Component: Nightly Tester

GCC 4.3 refuses to compile 2006-01-23-InitializedBitField.c with these errors:
2006-01-23-InitializedBitField.c:49: error: width of 'D' exceeds its type
2006-01-23-InitializedBitField.c:50: error: width of 'D2' exceeds its type
2006-01-23-InitializedBitField.c:71: error: width of 'D' exceeds its type
2006-01-23-InitializedBitField.c:72: error: width of 'D2' exceeds its type
2006-01-23-InitializedBitField.c:79: error: width of 'D' exceeds its type
because of this construct:
struct S7 {
_Bool D : 8;
_Bool D2 : 8;
int D3 : 8;
long long : 9;
float B;
} s7 = { 1, 0, 123, 1.023f };
which is fair. It may be that the ABI defines that type to be 8 bits or
whatever in memory, but that doesn't mean you can demand it be any larger than
1 bit. This construct should be removed from the test.
