7643ca5c2b The code section for an ISR has a specific address. 
Currently, whether a function is ISR or not is encoded in the section attribute for that function.

6e303cb9fa Handle DBG_VALUE mixed with labels when doing PHI 
elimination.  Before a DBG_VALUE could affect codegen.
The solution here is imperfect and not final.

llvm-gcc but has been replaced with pad argument which don't need any
special backend support.

c2385a0741 Split the main for-each-use loop again, this time for GenerateTruncates, 
as it also peeks at which registers are being used by other uses. This
makes LSR less sensitive to use-list order.

so reverting.  Temporarily I hope.

7dc9747e89 Put repeated empty pattern into the AQI instruction class. 
We could almost use a multiclass for the signed/unsigned instructions, but
there are only 6 of them so I guess it's not worth it.

ac8a3d0b5b It turns out that we emitted completely wrong common EH frame since the early beginning! The "z" CIE augmentation mark indicates that there is an extra word containing the size of augmentation section. However, even for frames w/o any augmentation data we emitted size uleb! (this is the case of "unwinding through C code"). Thus frame moves information was emitterd completely wrong.

014bf215c3 Split SelectionDAGISel::IsLegalAndProfitableToFold to 
IsLegalToFold and IsProfitableToFold. The generic version of the later simply checks whether the folding candidate has a single use.

This allows the target isel routines more flexibility in deciding whether folding makes sense. The specific case we are interested in is folding constant pool loads with multiple uses.

ce947366ec When complicated expressions are broken down into subexpressions 
with multiplication by constants distributed through, occasionally
those subexpressions can include both x and -x. For now, if this
condition is discovered within LSR, just prune such cases away,
as they won't be profitable. This fixes a "zero allocated in a
base register" assertion failure.

f0907fe590 Enable the inlinehint attribute in the Inliner. 
Functions explicitly marked inline will get an inlining threshold slightly
more aggressive than the default for -O3. This means than -O3 builds are
mostly unaffected while -Os builds will be a bit bigger and faster.

The difference depends entirely on how many 'inline's are sprinkled on the
source.

In the CINT2006 suite, only these tests are significantly affected under -Os:

               Size   Time
471.omnetpp   +1.63% -1.85%
473.astar     +4.01% -6.02%
483.xalancbmk +4.60%  0.00%

Note that 483.xalancbmk runs too quickly to give useful timing results.

c12da8d30a When save/restoring CR at prolog/epilog, in a large 
stack frame, the prolog/epilog code was using the same
register for the copy of CR and the address of the save slot.  Oops.
This is fixed here for Darwin, sort of, by reserving R2 for this case.
A better way would be to do the store before the decrement of SP,
which is safe on Darwin due to the red zone.

SVR4 probably has the same problem, but I don't know how to fix it;
there is no red zone and R2 is already used for something else.
I'm going to leave it to someone interested in that target.

Better still would be to rewrite the CR-saving code completely;
spilling each CR subregister individually is horrible code.

   merge two globals in different address spaces.

fe61fb1e10 Add a new pass on machine instructions to optimize away PHI cycles that 
reduce down to a single value.  InstCombine already does this transformation
but DAG legalization may introduce new opportunities.  This has turned out to
be important for ARM where 64-bit values are split up during type legalization:
InstCombine is not able to remove the PHI cycles on the 64-bit values but
the separate 32-bit values can be optimized.  I measured the compile time 
impact of this (running llc on 176.gcc) and it was not significant.
