4.0.2 seems to fail also, maybe a testsuite bug? Still somebody needs to
investigate closer.

Disassembly with the first two checks removed (only the third aborts):
foo:
.LFB2:
subq $24, %rsp #,
.LCFI0:
movl x+8(%rip), %eax #, tmp62
movl 16(%rsp), %edx #, tmp60
movq %rdi, 8(%rsp) # a, a
andl $2147483647, %eax #, tmp62
andl $2147483647, %edx #, tmp60
cmpl %eax, %edx # tmp62, tmp60
jne .L6 #,
addq $24, %rsp #,
ret
.L6:
call abort #
main:
.LFB3:
subq $8, %rsp #,
.LCFI1:
movl x+8(%rip), %eax #, tmp62
movw $30216, x(%rip) #, x.a
movb $1, x+4(%rip) #, x.b.c.d
movq x(%rip), %rdi # x, x
andl $-2147483648, %eax #, tmp62
orl $32766, %eax #, tmp62
movl %eax, x+8(%rip) # tmp62,
call foo #
xorl %eax, %eax # <result>
addq $8, %rsp #,
ret
it looks like we are confused on where we passed the structure by value.
It's in %rdi and %eax, while we think it got passed on stack(!?) in foo.
Someone with more x86_64 ABI knowledge has to look into this.

------- Comment #6 from matz at suse dot de 2005-11-21 14:25 -------
Something is fishy. Iff registers are used for passing then it would have to
be %rdi and %rsi (not %rax)! So the high part of this struct (where the
bitfield lies) is not passed at all here. Per ABI this whole struct
should be passed in registers (it's not larger than two eightbytes, and
both eightbytes have class INTEGER (they contain no unaligned fields or
other fancy stuff)).

3.2.3 also gets this wrong the same way.
The callee side says the struct comes on the stack.
The caller side says the struct goes in via %rdi.
Which one is correct?

------- Comment #9 from pinskia at gcc dot gnu dot org 2005-11-21 15:35 -------
Here is the rtl which is produced by expanding foo(x):
(insn 15 13 16 (set (reg/f:DI 63)
(symbol_ref:DI ("x") <var_decl 0x2aaaab15eb00 x>)) -1 (nil)
(nil))
(insn 16 15 17 (set (reg:DI 62)
(mem/s/c:DI (reg/f:DI 63) [4 x+0 S8 A32])) -1 (nil)
(nil))
(insn 17 16 18 (set (reg:DI 5 di)
(reg:DI 62)) -1 (nil)
(nil))
(call_insn 18 17 0 (call (mem:QI (symbol_ref:DI ("foo") [flags 0x3]
<function_decl 0x2aaaab15fb00 foo>) [0 S1 A8])
(const_int 0 [0x0])) -1 (nil)
(expr_list:REG_EH_REGION (const_int 0 [0x0])
(nil))
(expr_list:REG_DEP_TRUE (use (reg:DI 5 di))
(nil)))
Obviously this is wrong as it only passes one half of the struct.
