Other than the EH frame registration, this patch also implements support for GOT relocations which are used to locate the personality function on MachO. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181167 91177308-0d34-0410-b5e6-96231b3b80d8 2013-05-04T20:14:14Z Tim Northover Tim.Northover@arm.com 2013-05-04T20:14:14Z urn:sha1:d52eaae157e661f280d0a71aabc060602ffc4424 This is about the simplest relocation, but surprisingly rare in actual code. It occurs in (for example) the MCJIT test test-ptr-reloc.ll. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181134 91177308-0d34-0410-b5e6-96231b3b80d8 2013-05-04T20:14:09Z Tim Northover Tim.Northover@arm.com 2013-05-04T20:14:09Z urn:sha1:4a9b6b798d5ea335f5f29d278db83b830ae4a564 As with global accesses, external functions could exist anywhere in memory. Therefore the stub must create a complete 64-bit address. This patch implements the fragment as (roughly): movz x16, #:abs_g3:somefunc movk x16, #:abs_g2_nc:somefunc movk x16, #:abs_g1_nc:somefunc movk x16, #:abs_g0_nc:somefunc br x16 In principle we could save 4 bytes by using a literal-load instead, but it is unclear that would be more efficient and can only be tested when real hardware is readily available. This allows (for example) the MCJIT test 2003-05-07-ArgumentTest to pass on AArch64. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181133 91177308-0d34-0410-b5e6-96231b3b80d8 2013-05-04T20:14:04Z Tim Northover Tim.Northover@arm.com 2013-05-04T20:14:04Z urn:sha1:654c2d6b7a9274fc281c30c0e91419aadb6dc78a The large memory model (default and main viable for JIT) emits addresses in need of relocation as movz x0, #:abs_g3:somewhere movk x0, #:abs_g2_nc:somewhere movk x0, #:abs_g1_nc:somewhere movk x0, #:abs_g0_nc:somewhere To support this we must implement those four relocations in the dynamic loader.

This change implements very basic infrastructure in the RuntimeDyldELF file and allows (for example) the test-shift.ll MCJIT test to pass on AArch64. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181131 91177308-0d34-0410-b5e6-96231b3b80d8 2013-05-03T14:15:35Z Richard Sandiford rsandifo@linux.vnet.ibm.com 2013-05-03T14:15:35Z urn:sha1:6fc2ad62e23673ef829c9c4bbf62743d30928a5b Another step towards reinstating the SystemZ backend. I'll commit the configure changes separately (TARGET_HAS_JIT etc.), then commit a patch to enable the MCJIT tests on SystemZ. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181015 91177308-0d34-0410-b5e6-96231b3b80d8 2013-05-01T22:58:00Z Filip Pizlo fpizlo@apple.com 2013-05-01T22:58:00Z urn:sha1:0e1327e4aa1426aaa3f99a2cbfcb1f2b575791ad CodeModel: It's now possible to create an MCJIT instance with any CodeModel you like. Previously it was only possible to create an MCJIT that used CodeModel::JITDefault. EnableFastISel: It's now possible to turn on the fast instruction selector. The CodeModel option required some trickery. The problem is that previously, we were ensuring future binary compatibility in the MCJITCompilerOptions by mandating that the user bzero's the options struct and passes the sizeof() that he saw; the bindings then bzero the remaining bits. This works great but assumes that the bitwise zero equivalent of any field is a sensible default value. But this is not the case for LLVMCodeModel, or its internal equivalent, llvm::CodeModel::Model. In both of those, the default for a JIT is CodeModel::JITDefault (or LLVMCodeModelJITDefault), which is not bitwise zero. Hence this change introduces LLVMInitializeMCJITCompilerOptions(), which will initialize the user's options struct with defaults. The user will use this in the same way that they would have previously used memset() or bzero(). MCJITCAPITest.cpp illustrates the change, as does the comment in ExecutionEngine.h. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180893 91177308-0d34-0410-b5e6-96231b3b80d8 2013-05-01T20:59:00Z Filip Pizlo fpizlo@apple.com 2013-05-01T20:59:00Z urn:sha1:40be1e85665d10f5444186f0e7106e368dd735b8 the things, and renames it to CBindingWrapping.h. I also moved CBindingWrapping.h into Support/. This new file just contains the macros for defining different wrap/unwrap methods. The calls to those macros, as well as any custom wrap/unwrap definitions (like for array of Values for example), are put into corresponding C++ headers. Doing this required some #include surgery, since some .cpp files relied on the fact that including Wrap.h implicitly caused the inclusion of a bunch of other things. This also now means that the C++ headers will include their corresponding C API headers; for example Value.h must include llvm-c/Core.h. I think this is harmless, since the C API headers contain just external function declarations and some C types, so I don't believe there should be any nasty dependency issues here. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180881 91177308-0d34-0410-b5e6-96231b3b80d8
