Re: c/8467: Bug in sibling call optimization


Hi,

it turns out this bug is easily fixed with an intermediate move insn covering 
the case when DECL_MODE differs from the mode of the DECL_RTL.

Bootstrap on powerpc-linux-gnu is currently runnning.

OK to commit patch&testcase to mainline and branch after the bootstrap 
completed successfully?

Franz.


	PR c/8467
	* stmt.c (tail_recursion_args): Handle DECL_MODE differing from the
	mode of DECL_RTL case.
