Duncan Sands 4e7263b86f Adjust this test for the fact that the stores are no longer 
being combined (which is being tracked as PR8699).

Tobias Grosser 083379f815 Move check of command line options after command line parsing. 
The check to not allow -analyze and -disable-output at the same time was done
before parsing the command line flags. Therefore it never triggered, and in case
both options where used opt segfaulted. Fix this by moving this check a after
command line parsing.

Jim Grosbach d35424f9ca XFAIL for now. If someone with access to an ARM/Linux host wants to have a look 
that would be great. They're ARM JIT failures, so without that, it's tough.

Duncan Sands 050d93cb5a This test dates from the time when llvm-gcc had problems if two types were 
named the same, so it had to qualify type names according to the enclosing
scope to ensure uniqueness.  This is no longer needed for correctness (though
it may be helpful when reading the IR), so this test has lost its importance.
Zap it because dragonegg will never be able to produce the qualified type name
since modern gcc zaps language specific info (such as whether a type is nested
inside another - needed to get X::Y here) before dragonegg is reached.

Rafael Espindola bf792065a9 Add a fast path to EvaluateSymbolicAdd. This avoids computing symbol addresses 
which then avoids running EnsureValid.
This cuts the assembly time of the testcase in PR8711 from 2:50 minutes to 1
minute.

Bob Wilson 4375586bd9 Simplify code in Neon intrinsics. No functional changes intended. 
For most intrinsics, there is no need to allocate a temporary to hold the
result value; just return it directly.

 2010-12-02 07:44:23 +00:00
Bob Wilson 79026235e6 Assign arguments of Neon intrinsic macros to local temporaries. 
Since we're casting them for the calls to the builtins, we need this to
make sure their types get checked in the same way they would if the intrinsics
were implemented as inline functions.

Rafael Espindola 60ebca9aaf The sections that the ELF object writer has to create are very simple and 
contain only data. Handle them specially instead of using AddSectionToTheEnd.
This moves a hack from the generic assembler to the elf writer. It is also
a bit faster and should make other improvements easier.

Bob Wilson 014fe01ac8 Use statement expressions in Neon intrinsics defined as macros. 
This is in preparation for adding assignments to temporaries to ensure
that the proper type checking is done.

Bob Wilson ec626b09cb Add a missing cast for Neon vsbl results. 
The bitwise operations are always done with unsigned values, but the result may
be signed.

Bob Wilson a9ea9ef840 Add casts in arm_neon.h for result values in inline functions as well as macros. 
We should not rely on lax-vector-conversions for these intrinsics to work.

Jakob Stoklund Olesen 4be0bd79a4 Implement the first half of LiveDebugVariables. 
Scan the MachineFunction for DBG_VALUE instructions, and replace them with a
data structure similar to LiveIntervals. The live range of a DBG_VALUE is
determined by propagating it down the dominator tree until a new DBG_VALUE is
found. When a DBG_VALUE lives in a register, its live range is confined to the
live range of the register's value.

LiveDebugVariables runs before coalescing, so DBG_VALUEs are not artificially
extended when registers are joined.

The missing half will recreate DBG_VALUE instructions from the intervals when
register allocation is complete.

The pass is disabled by default. It can be enabled with the temporary command
line option -live-debug-variables.
