Another test. I compiled the following code: https://godbolt.org/z/hVCAUB
#include <stdint.h>
struct Bits {
unsigned A : 1;
uint8_t x;
};
int foo = sizeof(struct Bits);
As you can see in the Compiler Explorer, normal Linux/x86_64 outputs value 4 for `foo`:
foo:
.long 4 # 0x4
However, for the compiler I'm dealing with I'm getting the following output:
size.o: file format pe-x86-64
Disassembly of section .data:
0000000000000000 <foo>:
0: 08 00 or %al,(%rax)
...
So apparently this particular build of GCC 8 uses 8 bytes for the struct with bitfields.
