* [weak vtables] Remove a bunch of weak vtablesJuergen Ributzka2013-11-191-0/+3
| | | | | | | | | | | | This patch removes most of the trivial cases of weak vtables by pinning them to a single object file. The memory leaks in this version have been fixed. Thanks Alexey for pointing them out. Differential Revision: http://llvm-reviews.chandlerc.com/D2068 Reviewed by Andy llvm-svn: 195064
* Revert r194865 and r194874.Alexey Samsonov2013-11-181-3/+0
| | | | | | | | | | | | This change is incorrect. If you delete virtual destructor of both a base class and a subclass, then the following code: Base *foo = new Child(); delete foo; will not cause the destructor for members of Child class. As a result, I observe plently of memory leaks. Notable examples I investigated are: ObjectBuffer and ObjectBufferStream, AttributeImpl and StringSAttributeImpl. llvm-svn: 194997

* Add a MCTargetStreamer interface.Rafael Espindola2013-10-081-1/+45
| | | | | | | | | | | | | This patch fixes an old FIXME by creating a MCTargetStreamer interface and moving the target specific functions for ARM, Mips and PPC to it. The ARM streamer is still declared in a common place because it is used from lib/CodeGen/ARMException.cpp, but the Mips and PPC are completely hidden in the corresponding Target directories. I will send an email to llvmdev with instructions on how to use this. llvm-svn: 192181
* [PowerPC] Support powerpc64le as a syntax-checking target.Bill Schmidt2013-07-261-3/+20
| | | | | | | | | | | | | | | | | | | | | | | This patch provides basic support for powerpc64le as an LLVM target. However, use of this target will not actually generate little-endian code. Instead, use of the target will cause the correct little-endian built-in defines to be generated, so that code that tests for __LITTLE_ENDIAN__, for example, will be correctly parsed for syntax-only testing. Code generation will otherwise be the same as powerpc64 (big-endian), for now. The patch leaves open the possibility of creating a little-endian PowerPC64 back end, but there is no immediate intent to create such a thing. The LLVM portions of this patch simply add ppc64le coverage everywhere that ppc64 coverage currently exists. There is nothing of any import worth testing until such time as little-endian code generation is implemented. In the corresponding Clang patch, there is a new test case variant to ensure that correct built-in defines for little-endian code are generated. llvm-svn: 187179
* [PowerPC] Always use "assembler dialect" 1Ulrich Weigand2013-07-081-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A setting in MCAsmInfo defines the "assembler dialect" to use. This is used by common code to choose between alternatives in a multi-alternative GNU inline asm statement like the following: __asm__ ("{sfe|subfe} %0,%1,%2" : "=r" (out) : "r" (in1), "r" (in2)); The meaning of these dialects is platform specific, and GCC defines those for PowerPC to use dialect 0 for old-style (POWER) mnemonics and 1 for new-style (PowerPC) mnemonics, like in the example above. To be compatible with inline asm used with GCC, LLVM ought to do the same. Specifically, this means we should always use assembler dialect 1 since old-style mnemonics really aren't supported on any current platform. However, the current LLVM back-end uses: AssemblerDialect = 1; // New-Style mnemonics. in PPCMCAsmInfoDarwin, and AssemblerDialect = 0; // Old-Style mnemonics. in PPCLinuxMCAsmInfo. The Linux setting really isn't correct, we should be using new-style mnemonics everywhere. This is changed by this commit. Unfortunately, the setting of this variable is overloaded in the back-end to decide whether or not we are on a Darwin target. This is done in PPCInstPrinter (the "SyntaxVariant" is initialized from the MCAsmInfo AssemblerDialect setting), and also in PPCMCExpr. Setting AssemblerDialect to 1 for both Darwin and Linux no longer allows us to make this distinction. Instead, this patch uses the MCSubtargetInfo passed to createPPCMCInstPrinter to distinguish Darwin targets, and ignores the SyntaxVariant parameter. As to PPCMCExpr, this patch adds an explicit isDarwin argument that needs to be passed in by the caller when creating a target MCExpr. (To do so this patch implicitly also reverts commit 184441.) llvm-svn: 185858
* Remove the MachineMove class.Rafael Espindola2013-05-131-4/+5
| | | | | | | | | | | | 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. llvm-svn: 181680

* Use the new script to sort the includes of every file under lib.Chandler Carruth2012-12-031-2/+2
| | | | | | | | | | | | | | | | | Sooooo many of these had incorrect or strange main module includes. I have manually inspected all of these, and fixed the main module include to be the nearest plausible thing I could find. If you own or care about any of these source files, I encourage you to take some time and check that these edits were sensible. I can't have broken anything (I strictly added headers, and reordered them, never removed), but they may not be the headers you'd really like to identify as containing the API being implemented. Many forward declarations and missing includes were added to a header files to allow them to parse cleanly when included first. The main module rule does in fact have its merits. =] llvm-svn: 169131
* Fix initial frame state on powerpc64.Ulrich Weigand2012-11-281-1/+1
| | | | | | | | | The createPPCMCAsmInfo routine used PPC::R1 as the initial frame pointer register, but on PPC64 the 32-bit R1 register does not have a corresponding DWARF number, causing invalid CIE initial frame state to be emitted. Fix by using PPC::X1 instead. llvm-svn: 168799
