Bug ID: 93476
Summary: int bit fields waste space
Product: gcc
Version: 7.4.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: doug at cs dot dartmouth.edu
Target Milestone: ---
sizeof(struct{ unsigned int a:2; }) is 4. 3 out of the 4
bytes are gratuitously wasted.
A workaround is struct{ unsigned char a:2; }, whose size is 1,
but this is implementation-defined syntax and not portable.
