* Fix known typosAlp Toker2014-01-24

* Report lli remote IO errors consistentlyAlp Toker2014-01-24
| | | | | | | | | This enables IO error reports in both the child and server processes. The scheme still isn't entirely satisfactory and output is jumbled but it beats having no output at all. This will hopefully unblock ARM support (PR18057). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200017 91177308-0d34-0410-b5e6-96231b3b80d8

* Replace the interim lli build fix with something cleanerAlp Toker2014-01-23
| | | | | | | | | | Eliminates the LLI_BUILDING_CHILD build hack from r199885. Also add a FIXME to remove code that tricks the tests into passing when the feature fails to work. Please don't do stuff like this, the tests exist for a reason! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@199929 91177308-0d34-0410-b5e6-96231b3b80d8

* Interim build fix for MakefilesAlp Toker2014-01-23
| | | | | | Looks like some parts still need detangling. Let's see if this holds for now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@199885 91177308-0d34-0410-b5e6-96231b3b80d8

* Refactor lli-child-target to remove duplicated codeAlp Toker2014-01-23
| | | | | | | | | | | | | | Eliminate the copies LLVM's System mmap and cache invalidation code. These were slowly drifting away from the original version, and moreover the copied code was a dead end in terms of portability. We now statically link to Support but in practice with stripping this adds next to no weight to the resultant binary. Also avoid installing lli-child-target to the user's $PATH. It's not meant to be run directly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@199881 91177308-0d34-0410-b5e6-96231b3b80d8
* Tweak r199835 to use can_execute() instead of exists()Alp Toker2014-01-22
| | | | | | | The execution code path crashes if it can't execute the binary so we might as well take precautions here. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@199844 91177308-0d34-0410-b5e6-96231b3b80d8

* Sanitize MCJIT remote executionRenato Golin2014-01-14
| | | | | | | | | | | | MCJIT remote execution (ChildTarget+RemoteTargetExternal) protocol was in dire need of refactoring. It was fail-prone, had no error reporting and implemented the same message logic on every single function. This patch rectifies it, and makes it work on ARM, where it was randomly failing. Other architectures shall profit from this change as well, making their buildbots and releases more reliable. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@199261 91177308-0d34-0410-b5e6-96231b3b80d8

* MCJIT-remote: __main should be resolved in child context.NAKAMURA Takumi2013-10-27
| | | | | | | | | | | | | | | | - Mark tests as XFAIL:cygming in test/ExecutionEngine/MCJIT/remote. Rather to suppress them, I'd like to leave them running as XFAIL. - Revert r193472. RecordMemoryManager no longer resolves __main on cygming. There are a couple of issues. - X86 Codegen emits "call __main" in @main for targeting cygming. It is useless in JIT. FYI, tests are passing when emitting __main is disabled. - Current remote JIT does not resolve any symbols in child context. FIXME: __main should be disabled, or remote JIT should resolve __main. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@193498 91177308-0d34-0410-b5e6-96231b3b80d8

* Adding support for deregistering EH frames with MCJIT.Andrew Kaylor2013-10-16
| | | | | | | | Patch by Yaron Keren git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@192753 91177308-0d34-0410-b5e6-96231b3b80d8
* Fixing problems in lli's RemoteMemoryManager.Andrew Kaylor2013-10-11
| | | | | | | | | | This fixes a problem from a previous check-in where a return value was omitted. Previously the remote/stubs-remote.ll and remote/stubs-sm-pic.ll tests were reporting passes, but they should have been failing. Those tests attempt to link against an external symbol and remote symbol resolution is not supported. The old RemoteMemoryManager implementation resulted in local symbols being used for resolution and the child process crashed but the test didn't notice. With this check-in remote symbol resolution fails, and so the test (correctly) fails. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@192514 91177308-0d34-0410-b5e6-96231b3b80d8
