[llvm-dev] reviving LLVM on Solaris x86/SPARC platform

[Hal Finkel via llvm-dev]

Hi, Fedor,

That's good news. As you've indicated, the best way to get the changes 
reviewed is to break them into small pieces with good regressions tests. 
These should be uploaded to our code-review site 
(https://reviews.llvm.org/, see 
http://llvm.org/docs/Phabricator.html#requesting-a-review-via-the-web-interface 
for more information). Please make sure the patch descriptions fully 
describe the changes being proposed, and take care to follow the 
instructions regarding generating full-context diffs and adding the 
correct mailing lists as subscribers for each review.
