Provide correct DWARF register numbering for debug information emission on x86-32/Darwin.
This should fix bunch of issues.

Need to handle any 'nest' parameter before integer
parameters, since otherwise it won't be passed in
the right register. With this change trampolines
work on x86-64 (thanks to Luke Guest for providing
access to an x86-64 box).

Revert the part of 45849 that treated weak globals
as weak globals rather than commons. While not wrong,
this change tickled a latent bug in Darwin's strip,
so revert it for now as a workaround.

it should work, but I have no machine to test
it on. Committed because it will at least
cause no harm, and maybe someone can test it
for me!

make it more clear that this predicate only applies to scalar FP types.2008-01-16T06:24:21ZChris Lattnersabre@nondot.org2008-01-16T06:24:21Zurn:sha1:78631168d1179415c466620ec99ec626d4a35956

introduce a isTypeInSSEReg predicate, which allows us to simplify2008-01-16T06:19:45ZChris Lattnersabre@nondot.org2008-01-16T06:19:45Zurn:sha1:1956d1567671ef083efc19c001f5c1d121542aa6
some code. No functionality change.

My previous commit had an incomplete message, it should have been:2008-01-16T05:56:59ZChris Lattnersabre@nondot.org2008-01-16T05:56:59Zurn:sha1:7ff79c2d9d5e0c014ca8283cd38f5fbf3dd67790
make the 'fp return in ST(0)' optimization smart enough to
look through token factor nodes. THis allows us to compile
testcases like CodeGen/X86/fp-stack-retcopy.ll into:
_carg:
subl $12, %esp
call L_foo$stub
fstpl (%esp)
fldl (%esp)
addl $12, %esp
ret
instead of:
_carg:
subl $28, %esp
call L_foo$stub
fstpl 16(%esp)
movsd 16(%esp), %xmm0
movsd %xmm0, 8(%esp)
fldl 8(%esp)
addl $28, %esp
ret
Still not optimal, but much better and this is a trivial patch. Fixing
the rest requires invasive surgery that is is not llvm 2.2 material.
