Scott Michel 8e17d02a1e CellSPU: Relax constraints on when to generate a X-form address, evidently

Dan Gohman ad2134d45d Initial support for anti-dependence breaking. Currently this code does not 
introduce any new spilling; it just uses unused registers.

Refactor the SUnit topological sort code out of the RRList scheduler and
make use of it to help with the post-pass scheduler.

Dan Gohman b5e055fa51 Move the scheduler constructor functions to SchedulerRegistry.h, to 
simplify header dependencies for front-ends that just want to choose
a scheduler and don't need all the scheduling machinery declarations.

Bill Wendling 66835479d7 - Make lowering of "add with overflow" customizable by back-ends. 
- Mark "add with overflow" as having a custom lowering for X86. Give it a null
  lowering representation for now.

llvm-svn: 59971
 2008-11-24 19:21:46 +00:00
Scott Michel 2e5df906f8 CellSPU: 
(a) Slight rethink on i64 zero/sign/any extend code - use a shuffle to
    directly zero-extend i32 to i64, but use rotates and shifts for
    sign extension. Also ensure unified register consistency.
(b) Add new test harness for i64 operations: i64ops.ll

Dan Gohman 5cc12a8e31 Check in the rest of this change. The isAntiDep flag needs to be passed 
to removePred because an SUnit can both data-depend and anti-depend
on the same SUnit.

llvm-svn: 59969

Dan Gohman 11e4be3717 Run post-RA scheduling after branch folding, as it tends to 
obscure tail-merging opportunities.

 2008-11-24 17:18:39 +00:00
Scott Michel efc8c7a292 CellSPU: 
(a) Improve the extract element code: there's no need to do gymnastics with
    rotates into the preferred slot if a shuffle will do the same thing.
(b) Rename a couple of SPUISD pseudo-instructions for readability and better
    semantic correspondence.
(c) Fix i64 sign/any/zero extension lowering.

llvm-svn: 59961
 2008-11-24 16:01:21 +00:00
Duncan Sands dc2dac181a If the type legalizer actually legalized anything 
(this doesn't happen that often, since most code
does not use illegal types) then follow it by a
DAG combiner run that is allowed to generate
illegal operations but not illegal types.  I didn't
modify the target combiner code to distinguish like
this between illegal operations and illegal types,
so it will not produce illegal operations as well
as not producing illegal types.

Zhongxing Xu 9165ed69af Add support for AllocaRegion extent with GDM. 
One design problem that is emerging is the signed-ness problem during static
analysis. Many unsigned value have to be converted into signed value because
it partipates in operations with signed values. 

On the other hand, we cannot blindly make all values occuring in static analysis
signed, because we do have cases where unsignedness is required, for example,
integer overflow detection.
