Chris Lattner c3748562bd Various passes before isel split edges and do other CFG-restructuring changes. 
isel has its own particular features that it wants in the CFG, in order to
reduce the number of times a constant is computed, etc.  Make sure that we
clean up the CFG before doing any other things for isel.  Doing so can
dramatically reduce the number of split edges and reduce the number of
places that constants get computed.  For example, this shrinks
CodeGen/Generic/phi-immediate-factoring.ll from 44 to 37 instructions on X86,
and from 21 to 17 MBB's in the output.  This is primarily a code size win,
not a performance win.

This implements CodeGen/Generic/phi-immediate-factoring.ll and PR1296.

Reid Spencer 4eefaab3f6 For PR1297:

Reid Spencer c3d87685ad For PR1297: 
Update these test cases to use proper signatures for bswap which is now
and overloaded intrinsic. Its name must be of the form llvm.bswap.i32.i32
since both the parameter and the result or of type "iAny". Also, the
bit counting intrinsics changed to always return i32.

llvm-svn: 35548

Reid Spencer 3a0843e734 For PR1297:

Reid Spencer a090ffb2ab For PR1297: 
Change getOperationName to return std::string instead of const char*

llvm-svn: 35545
 2007-04-01 07:32:19 +00:00
Reid Spencer eba021453b For PR1297: 
Implement bswap, ctpop, ctlz, and cttz utilizing the new overloaded
intrinsic feature of tblgen. By defining llvm_int_ty to have an ValueType
of iAny, any intrinsic using that type becomes an overloaded intrinsic.
This signals that a) any integer type could be used for that argument and
b) the intrinsic needs a suffix to match each such argument for the
actual intrinsic.

llvm-svn: 35544
 2007-04-01 07:30:57 +00:00
Reid Spencer c7c4880ab1 For PR1297: 
Intrinsic functions might need to be generated (if they are overloaded) so
returning a const char* is no longer possible. Change getOperationName to
return a std::string instead.

llvm-svn: 35543
 2007-04-01 07:28:37 +00:00
Reid Spencer be23fb0370 For PR1297: 
Change the interface to the getName, getType, getDeclaration methods to
include the "actual" types of the result/arguments. This is necessary to
support overloaded intrinsics.

llvm-svn: 35542
 2007-04-01 07:26:35 +00:00
Reid Spencer 2a2117c82d For PR1297: 
Implement "actual" argument types for the Intrinsic member functions. This
involves changing the getName, getType, and getDeclaration methods to have
optional parameters for the actual types. These are necessary in order for
the type/name to be constructed properly for overloaded intrinsics. Only
the caller knows the actual argument types desired.

llvm-svn: 35541
 2007-04-01 07:25:33 +00:00
Reid Spencer 7c57b88b27 For PR1297: 
1. Clear up confusion between "GotBits" and "ExpectBits". GotBits is the
   type actually provided. ExpectedBits is the type expected for the
   intrinsics. Before this patch, it was reversed!
2. Implement checks for overloaded intrinsics. This involves computing the
   suffix expected and making sure the suffix matches the function name. It
   also includes some intrinsic-specific checks such as ensuring that the
   bswap parameter and result are the same width and an even number of bytes.

llvm-svn: 35540
 2007-04-01 07:22:57 +00:00
Reid Spencer e67d0c226d For PR1297: 
Implement code generation for overloaded intrinsic functions. The basic
difference is that "actual" argument types must be provided when
constructing intrinsic names and types. Also, for recognition, only the
prefix is examined. If it matches, the suffix is assumed to match. The
suffix is checked by the Verifier, however.

llvm-svn: 35539
 2007-04-01 07:20:02 +00:00
Reid Spencer 51455e00dc For PR1297: 
Add an "iAny" ValueType as a place holder for an integer type of any
bit width. This is used for intrinsics overloading on integer type.
