Re: [RFA] mips, floating point arg passing

Hello Michael,


GDB is causing SIGFPE on target boards that have a FPU,
when compiled for a 32 bit ABI.


I've only worked with the n32 ABI so far, so I'm not familiar with
the EABI nor o32 ABI. But I presume you know what you're talking
about :-).

	* mips-tdep.c (mips_eabi_push_dummy_call): For 32 bit ABI, to
	decide how many registers it takes to pass a floating point
	argument, what matters is the size of a floating point register
	(not the size of a general purpose register).
	(mips_o32_push_dummy_call): Ditto.


I'm not sure I really have the knowledge to approve but Daniel asked
for help in that department, so I'll give it a try.

This patch seems pretty logical to me, so go ahead and commit. Is it
possible to run the testsuite on either o32, or on a target board?

I did -- but it was quite some time ago now, and I couldn't really put my hands on them. I'm pretty sure they got better. Certainly they didn't get worse.

Committing.
