Hello!

We should simply use curr_insn instead of an ugly hack.

2010-11-02  Uros Bizjak  <ubizjak@gmail.com>

	* config/mips/mips.md (call_internal): Pass curr_insn to
	mips_split_call.

Compile tested on x86_64-pc-linux-gnu for mips-elf cross.

OK?

Uros.

Please do the call splitters too.  OK with that change if it
passes regression testing.

Thanks,

Um, please do the _other_ call splitters too, sorry.
