Gabor Greif cb6832efe0 Fix an assertion abort on sparc. malloc(0) is allowed to 
return NULL.

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

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.

pred_iterator down to a single ivar.

Ted Kremenek abd77cccb8 Removed uninformative assertions that catch problems that will 
fire anyway at runtime due to a NULL dereference.

 2007-10-10 23:35:04 +00:00
Ted Kremenek 4d984579da Removed "height" of an AVL tree node from its Profile. This is 
implicitly captured by using the addresses of its children in the
profile.

 2007-10-09 21:41:00 +00:00
Ted Kremenek 12bfa1ccbc 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.

Dan Gohman ac546cc28f Mark the prefetch intrinsic as IntrWriteArgMem, instead of the 
default of IntrWriteMem, to at least indicate that it doesn't
"capture" the argument pointer.

Dan Gohman a160361c85 Migrate X86 and ARM from using X86ISD::{,I}DIV and ARMISD::MULHILO{U,S} to 
use ISD::{S,U}DIVREM and ISD::{S,U}MUL_HIO. Move the lowering code
associated with these operators into target-independent in LegalizeDAG.cpp
and TargetLowering.cpp.
