[Bug middle-end/19721] [meta-bug] optimizations that CSE still catches
--- Additional Comments From bonzini at gcc dot gnu dot org 2005-08-17
08:03 ---
This small testcase is a typical case of the optimizations that CSE path
following catches on PowerPC:
unsigned outcnt;
extern void flush_outbuf(void);
void
bi_windup(unsigned char *outbuf, unsigned char bi_buf)
{
outbuf[outcnt] = bi_buf;
if (outcnt == 16384)
flush_outbuf();
outbuf[outcnt] = bi_buf;
}
Loading outcnt takes *three* insns: one to load the high part of the address,
one to load the low part, one to load from memory. CSE reduces them to two by
combining the loading of the low part with the load from memory. With CSE path
following, in addition, CSE is able to factor the loads of the high part of the
address, and do just one of them.
Now here comes GCSE. If CSE path following is on, GCSE sees that the third
occurrence of outcnt is the same as the second, and eliminates it. If it is
off, GCSE is wasted to factor the loading of the address high parts.
So, if we remove a pseudo-global cse pass by disabling path following, it would
make sense to bump the default max-gcse-passes to 2.

Reduced new testcase:
struct fpos {
fpos(int __pos) {}
};
struct g {
g();
~g();
};
fpos seekoff(int b, int c)
{
g __buf;
if (b != -1 && c >= 0)
return fpos(-1);
else
return fpos(-1);
}
The issue here is (produced inside the compiler):
return ;
goto ;
Which means this PR 20681 is a dup of this as the problem is the same.

Sorry, I misunderstood you. The function is a part of a large project (namely,
u-boot-1.1.3).
What about this:
//--
char str1[]="123456789";
char str2[10];
int
main()
{
register volatile char* cptr asm ("r29");
cptr=str1;
asm volatile ("or 29,29,29"); //optimization barrier, supposedly
memcpy(str2,cptr,10);
return (int)cptr; //just for fun

Compile with -ffixed-r29.

[Bug rtl-optimization/23444] Volatile register access incorrectly optimized
--- Additional Comments From pinskia at gcc dot gnu dot org 2005-08-17

No, the type of the local register variable is a pointer to a volatile "char"
(or struct) and not a volative
register.
You want:
register char*volatile cptr asm ("r29");
With that it works correctly.

It just happened to work before 4.0.0 because we did not do that many optimizations which could have taken this into effect. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=23444
[Bug fortran/23446] New: Valid internal subprogram array argument declaration is not accepted.
I'm trying to declare an internal subprogram array argument size using a local variable inherited from the encompassing scope. I think the declaration looks legal, but I'm not 100% sure.
