* MC: Overhaul handling of .lcommBenjamin Kramer2012-09-071-0/+21
| | | | | | | | | | | | | - Darwin lied about not supporting .lcomm and turned it into zerofill in the asm parser. Push the zerofill-conversion down into macho-specific code. - This makes the tri-state LCOMMType enum superfluous, there are no targets without .lcomm. - Do proper error reporting when trying to use .lcomm with alignment on a target that doesn't support it. - .comm and .lcomm alignment was parsed in bytes on COFF, should be power of 2. - Fixes PR13755 (.lcomm crashes on ELF). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@163395 91177308-0d34-0410-b5e6-96231b3b80d8

* Continue cleanup of LIT, getting rid of the remaining artifacts from dejagnuEli Bendersky2012-03-251-8/+1
| | | | | | | | | | | | | | | | | | * Removed test/lib/llvm.exp - it is no longer needed * Deleted the dg.exp reading code from test/lit.cfg. There are no dg.exp files left in the test suite so this code is no longer required. test/lit.cfg is now much shorter and clearer * Removed a lot of duplicate code in lit.local.cfg files that need access to the root configuration, by adding a "root" attribute to the TestingConfig object. This attribute is dynamically computed to provide the same information as was previously provided by the custom getRoot functions. * Documented the config.root attribute in docs/CommandGuide/lit.pod git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@153408 91177308-0d34-0410-b5e6-96231b3b80d8
