* Make R600 non-experimental.Rafael Espindola2013-05-224-5/+11
| | | | | | | The r600 backend has been in tree for some time now. Marking it as non-experimental to avoid accidental breakage. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@182442 91177308-0d34-0410-b5e6-96231b3b80d8

* Define BYTE_ORDER on Solaris.Jakob Stoklund Olesen2013-05-212-1/+10

* Put RTDyldMemoryManager into its own file, and make it linked into Filip Pizlo2013-05-217-159/+194
| | | | | | | | | | | | | | | | | | | | libExecutionEngine. Move method implementations that aren't specific to allocation out of SectionMemoryManager and into RTDyldMemoryManager. This is in preparation for exposing RTDyldMemoryManager through the C API. This is a fixed version of r182407 and r182411. That first revision broke builds because I forgot to move the conditional includes of various POSIX headers from SectionMemoryManager into RTDyldMemoryManager. Those includes are necessary because of how getPointerToNamedFunction works around the glibc libc_nonshared.a thing. The latter revision still broke things because I forgot to include llvm/Config/config.h. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@182418 91177308-0d34-0410-b5e6-96231b3b80d8

* Fix PPC branch selection for counter-based branchesHal Finkel2013-05-211-3/+9
| | | | | | | | | | | | Although I had added some support for the BDZ/BDNZ branches into the selector (in r158204), I had not correctly adjusted the condition at the top of the loop. As a result, these branches were still essentially unsupported. This fixes PR16086. Unfortunately, any test case would be very large (because it would need to force the loop backedge to exceed the range of the 16-bit immediate). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@182385 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | | Revision r182233 partially reverted the change in r181200 to simplify JIT unif test #ifdefs, because that change caused a link error on some host operating systems where the export list requires the following symbols to be defined: JITTest_AvailableExternallyFunction JITTest_AvailableExternallyGlobal As discussed on the list, the commit reverts r182233 (and re-installs the full r181200 change), and instead fixes the link problem by moving those two symbols to the top of the file and unconditionally defining them. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@182367 91177308-0d34-0410-b5e6-96231b3b80d8

* Add a PPCCTRLoops verification passHal Finkel2013-05-203-0/+164
| | | | | | | | | | | | | | | | | | When asserts are enabled, this adds a verification pass for PPC counter-loop formation. Unfortunately, without sacrificing code quality, there is no better way of forming counter-based loops except at the (late) IR level. This means that we need to recognize, at the IR level, anything which might turn into a function call (or indirect branch). Because this is currently a finite set of things, and because SelectionDAG lowering is basic-block local, this can be done. Nevertheless, it is fragile, and failure results in a miscompile. This verification pass checks that all (reachable) counter-based branches are dominated by a loop mtctr instruction, and that no instructions in between clobber the counter register. If these conditions are not satisfied, then an ICE will be triggered. In short, this is to help us sleep better at night. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@182295 91177308-0d34-0410-b5e6-96231b3b80d8
