Summary: asm generated lhs expressions are discarded
Product: gcc
Version: tree-ssa
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: c
AssignedTo: unassigned at gcc dot gnu dot org
ReportedBy: marcus at jet dot franken dot de
CC: gcc-bugs at gcc dot gnu dot org
GCC build triplet: i686-pc-linux-gnu
GCC host triplet: i686-pc-linux-gnu
GCC target triplet: i686-pc-linux-gnu
Attached testcase reduces to f() { return; } instead of generating
a memory reference: (omit-frame-pointer is not the culprit, breaks with -O2
too)
gcc -c -O2 -fomit-frame-pointer xx.i ; objdump -d xx.o
00000000 <f>:
0: c3 ret
(This is reduced from WINE, TlsSetValue())

confirmed on tree-ssa (20030628). DCE is removing a store which is wrong.
This can reproduced without using inline-asm (at least on powerpc-apple-darwin6.6):
static inline int* k()
{
return (int*)(0xFFFF0001);
}
void g()
{
*k() = 0;
}
So somehow DCE is removing *-65535B = 0 or *t_2 = 0 where t is set by a asm.

Here is a sample without the inlining:
void h()
{
int *t;
__asm__(".byte 0x64\n\tmovl (0x18),%0" : "=r" (t));
*t = 0;
}
The store is not dead code but it is mark as so.

The 0 used is just a sample, it works as any constant or with function

Subject: Re: [tree-ssa] asm generated lhs
expressions are discarded
You need to specify volatile to let the compiler know you're doing
something odd.
Both test cases work if volatile is used together with a patch to
volatile support that I'm going to be committing momentarily.
Diego.

Why is an asm() statement with a pointer as output something special? Its just like any other function that returns a pointer, or?

Ah, yes, now I see. I had missed the assignment to 't' inside the asm
statement. I'll fix that.
The second test case seems borderline to me. I'm not a language lawyer,
but I don't know what are the rules wrt assigning using random integer
values to a pointer. We can mark the pointer with the 'may point to
global memory' attribute.
Diego.
