file test.c:
----------------------
enum stdcolor_enum {
black, blue, green, cyan,
red, magenta, brown, lightgray,
darkgray, lightblue, lightgreen, lightcyan,
lightred, lightmagenta, yellow, white
};
union mouse_color_union {
struct mouse_color_str {
unsigned deflt : 4;
unsigned leftbutton : 4;
unsigned rightbutton : 4;
unsigned middlebutton : 4;
unsigned topbutton : 4;
unsigned twobutton : 4;
unsigned invalid : 4;
unsigned infield : 4;
} colors;
unsigned all;
} conf;
const union mouse_color_union MOUSE_reset_colors = { .colors = {
.deflt = brown,
.leftbutton = red,
.rightbutton = green,
.middlebutton = lightcyan,
.topbutton = cyan,
.twobutton = magenta,
.invalid = black,
.infield = magenta,
}};
void fct (void)
{
conf = MOUSE_reset_colors;
}

Basically, the assembler lines in gcc-4.2:
movl MOUSE_reset_colors, %eax
movl %eax, conf
becomes in 4.3:
movl $0, conf
movb conf+3, %al
movb $70, conf
andl $15, %eax
orl $80, %eax
movb $-78, conf+1
movb $83, conf+2
movb %al, conf+3
which looks like a regression.
Thanks, etienne.

The gimplifier is inlining the value of MOUSE_reset_colors for some reason ...

------- Comment #2 from etienne_lorrain at yahoo dot fr 2008-08-17 19:31 -------
It is not related to bitfields, this also show the problem:
struct color { unsigned char red, green, blue, transparent; } cur_color;
static const struct color mycolor = { 200, 10, 30, 0 };
void fct(void)
{
cur_color = mycolor;
}
with gcc-4.3.1 cur_color is initialised with 4 "movb" (so address is encoded 4
times)
and with gcc-4.2 with a 32 bits constant and a single "movl".
It seems to be the old problem of gcc not having a "write combining" pass
(converting consecutive byte/word writes into single double word writes), and
the "fix" of defining an intermediate variable is no more working.

------- Comment #3 from etienne_lorrain at yahoo dot fr 2008-08-24 09:13 -------
Moreover, if in the first test.c program, you declare variable "conf"
volatile,
the assembly generated contains 8 writes to "conf", and that memory location
is *read* 7 times. If "conf" does not point to memory but to memory mapped I/O
ports (maybe not readable), that is invalid code generated for valid input.

------- Comment #5 from jakub at gcc dot gnu dot org 2008-11-21 15:29 -------
4.4 compiles this (at least at -O2) into:
movb $70, conf
movb $-78, conf+1
movb $83, conf+2
movb $80, conf+3
so this looks then as a dup of PR22141. Testcase without the unnecessary
enum etc.:
union U
{
struct
{
unsigned f1 : 4;
unsigned f2 : 4;
unsigned f3 : 4;
unsigned f4 : 4;
unsigned f5 : 4;
unsigned f6 : 4;
unsigned f7 : 4;
unsigned f8 : 4;
} f;
unsigned g;
} u;
const union U def = { .f = { .f1 = 6, .f2 = 4, .f3 = 2, .f4 = 11,
.f5 = 3, .f6 = 5, .f7 = 0, .f8 = 5 } };
void fn1 (void)
{
u = def;
}
void fn3 (union U *);
void fn2 (void)
{
union U v = def;
fn3 (&v);
}

By trying to declare:
volatile union U u;
In your Testcase without the unnecessary enum, the "u = def;" is compiled as:
movl $0, u
movl u, %eax
andl $-16, %eax
orl $6, %eax
movl %eax, u
movl u, %eax
andb $15, %al
orl $64, %eax
movl %eax, u
movl u, %eax
andb $240, %ah
orb $2, %ah
movl %eax, u
movl u, %eax
andb $15, %ah
orb $176, %ah
movl %eax, u
movl u, %eax
andl $-983041, %eax
orl $196608, %eax
movl %eax, u
movl u, %eax
andl $-15728641, %eax
orl $5242880, %eax
movl %eax, u
movl u, %eax
andl $268435455, %eax
orl $1342177280, %eax

------- Comment #7 from jakub at gcc dot gnu dot org 2008-11-21 16:21 -------
For structure assignments to volatile structures you really can't have any
expectations how many individual stores will be done. I guess that falls
under:
What constitutes an access to an object that has volatile-qualified type is
implementation-defined.

The number of writes for that volatile structure may or may not be a problem,
I am more concerned by the number of reads of some memory which may not be
readable at all.

I am using gcc-core-4.4-20081121.tar.bz2 with ia32-linux (Fedora9) and
applying your patch gives a better assembly, but still not the possible
"mov $0x12345678,address" - I still get 4 movb on my test.c or your testcase.
Maybe I shall get the latest SVN, or there is more files to patch than dse.c?
