Problem when build glibc on IA64

[袁立威]

I'm a guy working on IA64 and I need to compile glibc with gcc4.2.

I tried gcc version 4.2.2 to build glibc 2.5, 2.6 and 2.7, all failed with:

internal compiler error: RTL flag check: INSN_DELETED_P used with
unexpected rtx code 'plus' in output_constant_pool_1, at varasm.c:
3393

I also tried gcc verision 4.2.1, get this message too.

I search this error with google and find this is a bug already fixed
by gcc, so I'm confused.

If I'm wrong or miss understand something, please tell me.

Any suggestion is a pleasure.

Thanks and regards.
