* Fold 15 tiny test cases into a single file that implements theChandler Carruth2012-04-091-21/+0
| | | | | | | | | | | | | | | | | | | comprehensive testing of TLS codegen for x86. Convert all of the ones that were still using grep to use FileCheck. Remove some redundancies between them. Perhaps most interestingly expand the test cases so that they actually fully list the instruction snippet being tested. TLS operations are *very* narrowly defined, and so these seem reasonably stable. More importantly, the existing test cases already were crazy fine grained, expecting specific registers to be allocated. This just clarifies that no *other* instructions are expected, and fills in some crucial gaps that weren't being tested at all. This will make any subsequent changes to TLS much more clear during review. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@154303 91177308-0d34-0410-b5e6-96231b3b80d8

* Reduce code duplication on the TLS implementation.Rafael Espindola2009-04-071-2/+2
| | | | | | | | | | | | This introduces a small regression on the generated code quality in the case we are just computing addresses, not loading values. Will work on it and on X86-64 support. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@68552 91177308-0d34-0410-b5e6-96231b3b80d8
