Special handling is needed for the 64-bit PowerPC SVR4 ABI when a constant is initialized with a pointer to a function in a shared library. Because a function address is implemented as the address of a function descriptor, the use of copy relocations can lead to problems with initialization. GNU ld therefore replaces copy relocations with dynamic relocations to be resolved by the dynamic linker. This means the constant cannot reside in the read-only data section, but instead belongs in .data.rel.ro, which is designed for constants containing dynamic relocations. The implementation creates a class PPC64LinuxTargetObjectFile inheriting from TargetLoweringObjectFileELF, which behaves like its parent except to place constants of this sort into .data.rel.ro. The test case is reduced from the oggenc application. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181723 91177308-0d34-0410-b5e6-96231b3b80d8 2013-05-13T01:16:13Z Rafael Espindola rafael.espindola@gmail.com 2013-05-13T01:16:13Z urn:sha1:4a971705bc6030dc2e4338b3cd5cffa2e0f88b7b It was just a less powerful and more confusing version of MCCFIInstruction. A side effect is that, since MCCFIInstruction uses dwarf register numbers, calls to getDwarfRegNum are pushed out, which should allow further simplifications. I left the MachineModuleInfo::addFrameMove interface unchanged since this patch was already fairly big. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181680 91177308-0d34-0410-b5e6-96231b3b80d8 2013-05-11T02:38:11Z Rafael Espindola rafael.espindola@gmail.com 2013-05-11T02:38:11Z urn:sha1:d84ccfaf50c7843f31ffc74a8a8e33f779453d6e To add a frame now there is a dedicated addFrameMove which also takes care of constructing the move itself. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181657 91177308-0d34-0410-b5e6-96231b3b80d8 2013-05-10T18:16:59Z Rafael Espindola rafael.espindola@gmail.com 2013-05-10T18:16:59Z urn:sha1:6e53180db120b30f600ac31611a9dd47ef7f4921 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181618 91177308-0d34-0410-b5e6-96231b3b80d8 2013-05-08T17:51:39Z Roman Divacky rdivacky@freebsd.org 2013-05-08T17:51:39Z urn:sha1:fd94f0ab358ea12cf2b17c9628207b3fd11d40b4 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181452 91177308-0d34-0410-b5e6-96231b3b80d8 2013-05-08T17:50:07Z Ulrich Weigand ulrich.weigand@de.ibm.com 2013-05-08T17:50:07Z urn:sha1:a3967b6844f4be588c724ada3692e734bba65cf1 The patch I committed as revision 167864 introduced a regression that causes LLVM to no longer generate appropriate relocs for @ha/@l symbol references (but fail an assertion instead). This is fixed here by re-enabling support for the VK_PPC_GAS_HA16/ VK_PPC_GAS_LO16 variant kinds (and their Darwin variants) in PPCELFObjectWriter.cpp. Tested by running projects/test-suite in -m32 mode with the integrated assembler forced on. A standalone test case will be committed shortly as well. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181450 91177308-0d34-0410-b5e6-96231b3b80d8 2013-05-08T17:22:33Z Bill Schmidt wschmidt@linux.vnet.ibm.com 2013-05-08T17:22:33Z urn:sha1:a7f2ce85e5bd8d2826537f50ac510ef9fbe83792 This fixes bug 15821 similarly to the powerpc64-linux fix for bug 14779.
