Alkis Evlogimenos 08c5311729 Currently we cannot handle two-address instructions of the form: 
A = B op C where A == C, but this cannot really occur in practice
because of SSA form. Add an assert to check that just to be safe.

John Criswell 5782ca06fc Not all platforms supports sighandler_t, so I changed it to use the older 
return value from signal() (which should be the same type; it's just not
typedef'd).
This fixes the build on Solaris.

Chris Lattner 748e857996 Add new ExecutionEngine::getGlobalValueAtAddress method, which can efficiently 
turn a memory address back into the LLVM global object that starts at that
address.  Note that this won't cause any additional datastructures to be built
for clients of the EE that don't need this information.

Also modified some code to not access the GlobalAddress map directly.

compile when enabled.

John Criswell ceea5ad8c8 Updated from files in llvm/autoconf. This was done immediently following 
the renaming of aclocal.m4 to acinclude.m4.

John Criswell 7775323801 Moved aclocal.m4 to acinclude.m4. To re-generate the configure script, 
do the following:
% cd llvm/autoconf
% aclocal
% autoconf -o ../configure

This changes facilitaties the following:
1) It should be easier to incorporate new autoconf macros.
2) It allows for conversion to Automake (should we ever desire it).

Chris Lattner 6b668f228f Further revisions of the FDHandle idea. In this version we use ownership 
semantics that are the same as those used by std::auto_ptr.  This allows
copying of FDHandle's, but copying transfers ownership.

Chris Lattner 5d236005b0 Clean up a lot of the code I added yesterday by exposing the IntrinsicLowering 
implementation from the TargetMachine directly.

Alkis Evlogimenos a158dc8104 Reserve ECX and EDI instead of EBX and EDI. Since EBX is a callee 
saved register it has a longer free range than ECX (which is defined
every time there is a fnuction call) which makes ECX a better register
to reserve.

 2003-12-28 18:03:52 +00:00
Alkis Evlogimenos 43b587d94d Add coalescing to register allocator. A hint is added to each interval 
which denotes the register we would like to be assigned to (virtual or
physical). In register allocation, if this hint exists and we can map
it to a physical register (it is either a physical register or it is a
virtual register that already got assigned to a physical one) we use
that register if it is available instead of a random one in the free
pool.

llvm-svn: 10634
 2003-12-28 17:58:18 +00:00
Alkis Evlogimenos 52564b2071 Add TargetInstrInfo::isMoveInstr() to support coalescing in register 
allocation.
