Neil Booth 7e74b17ad2 Don't attempt to mask no bits

Dan Gohman dc35bd79ca Change the names used for internal labels to use the current 
function symbol name instead of a codegen-assigned function
number.

Thanks Evan! :-)

Evan Cheng b83a379f4f EXTRACT_SUBREG test case. 
llvm-svn: 42900
 2007-10-12 09:03:31 +00:00
Evan Cheng aa2d6ef81d 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.

Chris Lattner d8675e4915 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

Chris Lattner 7119397fa1 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.

specifiers.

Dan Gohman be37007e64 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.

llvm-svn: 42885
 2007-10-12 00:01:22 +00:00
Dan Gohman 2a7de41682 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.

Arnold Schwaighofer 9ccea99165 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

Chris Lattner 16a0de468f Push the rewriting APIs along. Build a trivial client that replaces tabs 
with x's for now.  The APIs are all unimplemented, so it doesn't do 
anything yet! :)

Fariborz Jahanian d797113659 Implemented parsing of objctive-c protocol conforming type used in 
an identifier statement. Fixed up pretty priting to print this type 
correctly.

Dale Johannesen 007aa378ad 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.
