SparcV8 backend skeleton
|
|
------------------------
|
|
|
|
This directory houses a 32-bit SPARC V8 backend employing an expander-based
|
|
instruction selector. It is not yet functionally complete. Watch
|
|
this space for more news coming soon!
|
|
|
|
Current expected test failures
|
|
------------------------------
|
|
|
|
Here are the currently-expected SingleSource failures for V8
|
|
(Some C++ programs are crashing in libstdc++ at the moment;
|
|
I'm not sure why.)

Here are the currently-expected MultiSource failures for V8:

* DANGER * analyzer will run the machine out of VM
|
|
(I don't know whether the following fail in cbe:)

Known SPEC failures for V8 (probably not an exhaustive list):
|
|
|
|
(llc) 134.perl
|
|
(llc) 177.mesa
|
|
(llc) 188.ammp -- FPMover bug?
|

(llc) 256.bzip2
|
|
(llc,cbe) 130.li
|
|
(native,llc,cbe) 126.gcc
|
|
(native,llc,cbe) 255.vortex
|
|
|
|
To-do
|
|
-----
|
|
|
|
* support shl on longs (fourinarow needs this)
|
|
* support casting 64-bit integers to FP types (fhourstones needs this)
|
|
* support FP rem
