Re-apply 103156 and 103157. 103156 didn't break anything. 10315 exposed a coalescer bug that's fixed by 103170.

%reg1039:1<def> = VMOVS %S1<kill>, pred:14, pred:%reg0
is not coalescable since none of the super-registers of S1 are in reg1039's
register class: DPR_VFP2. But it is still a legal copy instruction so it should
not assert.

float -> double (which happens because they are modelled as int(...)
functions), and add a testcase for isinf.

llvm-svn: 103167

this is generating correct but suboptimal (extra extend to double)
code for the float case.  Will investigate next.

automatic syscall restarting is disabled.

Also, fix the build on systems which don't define EWOULDBLOCK.

Adding pseudo 256-bit registers QQ0 . . . QQ7 to represent pairs of Q registers. These will be used to model VLD2 / VST2 instructions in order to get substantially better codegen for them.

EAGAIN and EWOULDBLOCK are used here.

Also, handle the case where a write call is interrupted after
some data has already been written.

method will sometimes return different results for the same input SourceLocations.  I haven't
unraveled this method completely yet, so this truly is a workaround until a better fix comes
along.

Users can write broken code that emits the same label twice with asm renaming,
detect this and emit a fatal backend error instead of aborting.

except it only skips implicit casts.

Also fix ObjCImplicitGetterSetterRefExpr's child_begin to skip the base expression
if it's actually a type reference (which you get with static property references).

llvm-svn: 103132

function attributes like byval get applied to the function 
definition. This fixes PR7058 and makes i386 llvm/clang bootstrap 
pass all the same tests as x86-64 bootstrap for me (the llvmc 
tests still fail in both).

that was causing PC-relative branch targets to be
evaluated incorrectly.  Also added support for
checking operand values to the llvm-mc tester.

llvm-svn: 103128

provide a note that shows where the copy-assignment operator was
needed. We used to have this, but I broke it during refactoring.
