limited to *-darwin.

hmm there appears to be a second issue - also showing on Darwin (perhaps
related to 202286) - my test was against 202275.

No: I did not test it although the initial fix worked for me). The comparison

On the basis that clang (Darwin11, Darwin12) defines the ABI - we should see
about this.  Presumably, this should be disabled for OS versions where
gcc-4.2/gcc-4.0 are the system compiler.

As of now, the documentation does not refer to this - the web page still points
to the older psABI.

Is there an official update to the System V psABI covering these regs?

 Those changes are not needed. If TARGET_64BIT is fasle all sse registers
 except xmm0-xmm7 should be fixed. Correct fix is 

snip

 Looks like this will break ABI. Before we returned true for e. g. xmm10.

indeed, that was worrying me too.

 I couldn't find Darwin ABI to check which behaivor is correct.

The ABI for [x86_64] Darwin *should be* the same as 
System V Application Binary Interface AMD64 Architecture Processor Supplement
Draft Version 0.99.5

it is possible that:
(a) GCC has been broken a while and this is just not covered by the test-suite.
(b) the system ABI has deviated from the referenced document.

However - regardless of the doc, the system ABI is effectively defined by
Apple's GCC-4.2.1 (or successor clang, where that is not the system default).

 If we want to keep current behaivor something like 

snip 

 Should work.

I will apply your revised patch (and keep the second amendment in reserve) and
do some compat tests to find out what we need to do to be compliant with the
system

thanks for the patch, iain.

Created attachment 30736
  -- http://gcc.gnu.org/bugzilla/attachment.cgi?id=30736action=edit
initial fix

AFAICT, the problem here is that 
TARGET_SSE  SSE_REGNO_P (regno) now produces a different answer from
pre-201915.

So, the patch attached is a necessary (but not proven to be sufficient) fix.

We need to audit all uses of SSE_REGNO_P () for darwin (at least).

AFAIU, the x86_64 Darwin ABI is the same as the linux/system V - so we should
be able to remove special-casing in some places (providing the SSE_REGPARM_MAX
values are the Right Fix and correctly specified).

I checked the Darwin x86_32 ABI info (briefly) and ISTM that the values for max
call arg usage of MMX and SSE regs in i386.h are right, so perhaps we can
remove more special-casing there too (not touched so far).

Will try some additional tests later - and I'd welcome Mike's PoV here on how
we prove sufficient.
