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 allows (for example) the test-global.ll MCJIT test to pass on AArch64. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181132 91177308-0d34-0410-b5e6-96231b3b80d8 2013-05-04T20:13:59Z Tim Northover Tim.Northover@arm.com 2013-05-04T20:13:59Z urn:sha1:85829bb98a998cff8f364c12d172da948ca225f4 R_AARCH64_PCREL32 is present in even trivial .eh_frame sections and so is required to compile any function without the "nounwind" attribute. 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 2013-04-30T15:40:54Z Rafael Espindola rafael.espindola@gmail.com 2013-04-30T15:40:54Z urn:sha1:e87dadc44b1544c35e13cf48dfe167109929a944 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180790 91177308-0d34-0410-b5e6-96231b3b80d8 2013-04-30T01:29:57Z Rafael Espindola rafael.espindola@gmail.com 2013-04-30T01:29:57Z urn:sha1:8e6e02a41bd21f8e919e812dbd7aa9ed5474bdbf This fixes 2013-04-04-RelocAddend.ll. We don't have a testcase for non external relocs with an Addend. I will try to write one. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180767 91177308-0d34-0410-b5e6-96231b3b80d8 2013-04-29T22:24:22Z Rafael Espindola rafael.espindola@gmail.com 2013-04-29T22:24:22Z urn:sha1:59a0e79631ed851d98cf9c2ba6fa5f9aafdfdc93 For regular object files this is only meaningful for common symbols. An object file format with direct support for atoms should be able to provide alignment information for all symbols. This replaces getCommonSymbolAlignment and fixes test-common-symbols-alignment.ll on darwin. This also includes a fix to MachOObjectFile::getSymbolFlags. It was marking undefined symbols as common (already tested by existing mcjit tests now that it is used). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180736 91177308-0d34-0410-b5e6-96231b3b80d8
