[Bug bootstrap/19796] New: Bootstrap fails: Unresolved data symbol "set_fpc_csr"

[billingd at gcc dot gnu dot org]

My mips-sgi-irix6.5 bootstraps have been failing since 25 Jan. (I have been 
travelling and didn't notice).
 - The last successful build was 2005-01-24 09:07 UTC
 - First failure was approx 2005-01-25 09:00 UTX

I suspect that the problem is due to:

2005-01-24  Richard Sandiford  <rsandifo@redhat.com>

	* config/mips/irix-csr.c: New file.
	* config/mips/t-iris6 (irix-csr.o): New rule to build it.
	(EXTRA_MULTILIB_PARTS): Add irix-csr.o.
	* config/mips/iris6.h (ENDFILE_SPEC): Include it in n32 and n64
	executables.

The error I see is:

Sigh.  Obviously the sys/fpu.h thing isn't as portable as I'd thought.
I wondered why your 4.0 reports had suddendly dropped off...

I have seen this technique mentioned on various web pages,
so I'd be interested to know what's different about your system.
But I suppose this whole issue doesn't matter that much.

I've reverted the offending patch.  I'll look into skipping or
XFAILing the IEEE subnormal tests for IRIX instead.

Richard

Thanks Richard.  I don't know what is different about my system either.
Happy to follow up if you are interested, but not a burning issue with me.

I can see the problem here once I compile with -v.  

get_fpc_csr and set_fpc_csr are in libc.so, but -lc linked before stage1/irix-csr.o,
so the routines aren't found.  If I run collect2 by hand with -lc after irix-csr.o
then all is well.
