* Fix wrong usages of CTR/MCTR where CTR8/MCTR8 was meant.Roman Divacky2011-06-03
| | | | | | | | | | | | | | - Check for MTCTR8 in addition to MTCTR when looking up a hazard. - When lowering an indirect call use CTR8 when targeting 64bit. - Introduce BCTR8 that uses CTR8 and use it on 64bit when expanding ISD::BRIND. The last change fixes PR8487. With those changes, we are able to compile a running "ls" and "sh" on FreeBSD/PowerPC64. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132552 91177308-0d34-0410-b5e6-96231b3b80d8

* Enable CFI on OS X.Rafael Espindola2011-04-30
| | | | | | | | | | | | | | | Currently the output should be almost identical to the one produced by CodeGen to make the transition easier. The only two differences I know of are: * Some files get an extra advance loc of size 0. This will be fixed when relaxations are enabled. * The optimization of declaring an EH symbol as an external variable is not implemented. This is a subset of adding the nounwind attribute, so we if really this at -O0 we should probably do it at the IL level. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@130623 91177308-0d34-0410-b5e6-96231b3b80d8

* Implement the "linker_private_weak" linkage type. This will be used forBill Wendling2010-07-01
| | | | | | | | | | | | | | | | | | | | | | | | Objective-C metadata types which should be marked as "weak", but which the linker will remove upon final linkage. However, this linkage isn't specific to Objective-C. For example, the "objc_msgSend_fixup_alloc" symbol is defined like this: .globl l_objc_msgSend_fixup_alloc .weak_definition l_objc_msgSend_fixup_alloc .section __DATA, __objc_msgrefs, coalesced .align 3 l_objc_msgSend_fixup_alloc: .quad _objc_msgSend_fixup .quad L_OBJC_METH_VAR_NAME_1 This is different from the "linker_private" linkage type, because it can't have the metadata defined with ".weak_definition". Currently only supported on Darwin platforms. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@107433 91177308-0d34-0410-b5e6-96231b3b80d8

* Eliminate the first have of the optimization which eliminates BRCONDDan Gohman2010-06-24
| | | | | | | | | | | | | | when the condition is constant. This optimization shouldn't be necessary, because codegen shouldn't be able to find dead control paths that the IR-level optimizer can't find. And it's undesirable, because it encourages bugpoint to leave "br i1 false" branches in its output. And it wasn't updating the CFG. I updated all the tests I could, but some tests are too reduced and I wasn't able to meaningfully preserve them. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@106748 91177308-0d34-0410-b5e6-96231b3b80d8
