Old Synopsis: Compiler crashes on inline assembly with internal error
New Synopsis: [<3.2.1,3.4> regression] ICE with inline assembly in instantiate_virtual_regs_1, at function.c:3974
State-Changed-From-To: open->analyzed
State-Changed-By: cae
State-Changed-When: Tue Jan 7 02:02:58 2003
State-Changed-Why:
Confirmed with 3.2.1-release and 3.4 (didn't test 3.3). This is a
regression from 3.2. Here's a reduced testcase:
void get_lsb(long long bb)
{
int index;
asm( "" : "=%al" (index) : "d" (&bb) : "%ecx");
}
This testcase crashes both, cc1 and cc1plus on 3.4.
