947b4a6c3d EXTRACT_SUBREG test case. 
llvm-svn: 42900
 2007-10-12 09:03:31 +00:00
Evan Cheng
d11cd4a095 EXTRACT_SUBREG coalescing support. The coalescer now treats EXTRACT_SUBREG like 
(almost) a register copy. However, it always coalesced to the register of the
RHS (the super-register). All uses of the result of a EXTRACT_SUBREG are sub-
register uses which adds subtle complications to load folding, spiller rewrite,
etc.

3c23c37233 Fix some 80 column violations. 
Fix DecomposeSimpleLinearExpr to handle simple constants better.
Don't nuke gep(bitcast(allocation)) if the bitcast(allocation) will
fold the allocation.  This fixes PR1728 and Instcombine/malloc3.ll

e47ae5fe94 make operator== work with non-equal sized bitvectors, as long as 
the extra bits are all zeros.  This allows  "010" and "010000" to be
treated as equal.

ab5c3ed0d1 Add intrinsics for sin, cos, and pow. These use llvm_anyfloat_ty, and so 
may be overloaded with vector types. And add a testcase for codegen for
these.

b9863c4738 Codegen support for vector intrinsics. 
Factor out the code that expands the "nasty scalar code" for unrolling
vectors into a separate routine, teach it how to handle mixed
vector/scalar operands, as seen in powi, and use it for several operators,
including sin, cos, powi, and pow.

Add support in SplitVectorOp for fpow, fpowi and for several unary
operators.

d47210011e Added tail call optimization to the x86 back end. It can be 
enabled by passing -tailcallopt to llc.  The optimization is
performed if the following conditions are satisfied:
* caller/callee are fastcc
* elf/pic is disabled OR
  elf/pic enabled + callee is in module + callee has
  visibility protected or hidden

0ee2a2fb59 Next PPC long double bits. First cut at constants. 
No compile-time support for constant operations yet,
just format transformations.  Make readers and
writers work.  Split constants into 2 doubles in
Legalize.

a8e090bd1c Added implementation of immutable (functional) maps and sets, as 
implemented on top of a functional AVL tree.  The AVL balancing code
is inspired by the OCaml implementation of Map, which also uses a functional
AVL tree.

Documentation is currently limited and cleanups are planned, but this code
compiles and has been tested.
