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
------------------------------
The SparcV8 backend works on many simple C++ SingleSource codes. Here
are the known SingleSource failures:
Regression/C++/EH/exception_spec_test
Regression/C++/EH/throw_rethrow_test
Benchmarks/Shootout-C++/moments
Benchmarks/Shootout-C++/random
Here are the known MultiSource test failures, neglecting FreeBench,
MallocBench, and Prolangs-C++:
Applications/lambda
Applications/d/make_dparser
Applications/hbd
Applications/hexxagon
Benchmarks/Fhourstones
Benchmarks/McCat/03-testtrie
Benchmarks/McCat/18-imp
Benchmarks/Olden/tsp
Benchmarks/Ptrdist/anagram
Benchmarks/Prolangs-C/bison/mybison
Benchmarks/Prolangs-C/fixoutput
Benchmarks/Prolangs-C/gnugo
Benchmarks/Prolangs-C/plot2fig
To-do
-----
* support shifts on longs
* support casting 64-bit integers to FP types
* support FP rem
* directly support select instructions
