[Bug c/15429] New: internal compiler error: in emit_move_insn_1, at expr.c:3510

[jgeorgal at uoc dot gr]

I get the error "internal compiler error: in emit_move_insn_1, at 
expr.c:3510", when trying to compile: 
 
--------START CODE (dummy.c)---------- 
 
void dummy (int value, void* arg) 
{ 
    long __pu_err; 
    __asm__ __volatile__( 
		"1:	movl %%eax,0(%2)\n"  
		"2:	movl %%edx,4(%2)\n" 
		: "=r"(__pu_err) : 
		"A" (((__typeof__(*(arg)))(value))),  
		"r" (((arg))), "i"(-14), "0"(__pu_err) 
		); 
} 
 
----------END CODE (dummy.c)---------- 
 
Try to compile with "gcc -c dummy.c" 
 
(this is actually the "affected" part of the expansion of the macro 
"__put_user(value, (void*) arg);(*)" which is part of linux (the kernel). Note 
that this call is wrong (it should be "(int*) arg", in which case everything 
works ok. The same for the "dummy" function if we declare "int* arg")) 
 
(*) in header <asm/uaccess.h> 
 
This "internal error" seems to affect "all" gcc versions. 
 
gcc (GCC) 3.3.3 (Debian 20040306) 
 
2.95.4 (error is "Internal compiler error in `emit_move_insn_1', at 
expr.c:2835")

No we do not need more information, I was just quoting from the error from gcc, sorry for the 
confusion.

My mistake. I realized it after posting. 
 
btw: added 2.95.4 version to "Known to fail".

Fixed in 3.5.0 by the tree-ssa merge:
: Search converges between 2004-05-11-trunk (#454) and 2004-05-14-trunk (#455).

sorry. my browser crashed during upload ( thats why there's no description ). 
 
Minimal case of this is: 
 
---START CODE (bug.c)--- 
void test( void *v ) 
 { 
  __asm__ 
   ( 
    "mov (%%eax),  %%ecx\n" 
    : 
    : "a"(v[0]) 
   ); 
 } 
---END CODE (bug.c)--- 
 
and it also fails on 3.3.4
