[Bug bootstrap/14221] Compiler from stage1 ICE on system header: Illegal instruction

[neroden at gcc dot gnu dot org]

------- Additional Comments From neroden at gcc dot gnu dot org  2004-02-28 23:10 -------
Apparently the compiler built in stage1 is ICEing on this code: 
 
# 127 "./include/machine/ansi.h" 3 4 
typedef int __attribute__((__mode__(__DI__))) __int64_t; 
typedef unsigned int __attribute__((__mode__(__DI__))) __uint64_t; 
# 139 "./include/machine/ansi.h" 3 4 
 
Which seems.... odd. 
 
Unless... just to verify, submitter, are you bootstrapping on a machine which 
is actually a Pentium 3?  If not, then the stage1 compiler, having been built 
with Pentium 3 opcodes, would be perfectly likely to die with illegal 
instructions. 
 
Otherwise, we have to track down why illegal instructions are being compiled 
into the stage1 compiler.

End of assembler dump.


It seems that this is the instructions that causes the SIGILL. What is strange
is that it should work. This instruction is part of P3 instruction set and
according to the CPUID utility output the CPU is P3. 
...
I think it must be some huge misinterpretation of facts on my side because
anything that uses vector extensions and is compiled with -msse gives me SIGILL.
I can bootstrap with just --with-arch=i686 fine.
