include/llvm/Analysis/DebugInfo.h to include/llvm/DebugInfo.h. The reasoning is because the DebugInfo module is simply an interface to the debug info MDNodes and has nothing to do with analysis. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159312 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-26There are a number of generic inline asm operand modifiers thatJack Carter
up to r158925 were handled as processor specific. Making them generic and putting tests for these modifiers in the CodeGen/Generic directory caused a number of targets to fail. This commit addresses that problem by having the targets call the generic routine for generic modifiers that they don't currently have explicit code for. For now only generic print operands 'c' and 'n' are supported.vi Affected files: test/CodeGen/Generic/asm-large-immediate.ll lib/Target/PowerPC/PPCAsmPrinter.cpp lib/Target/NVPTX/NVPTXAsmPrinter.cpp lib/Target/ARM/ARMAsmPrinter.cpp lib/Target/XCore/XCoreAsmPrinter.cpp lib/Target/X86/X86AsmPrinter.cpp lib/Target/Hexagon/HexagonAsmPrinter.cpp lib/Target/CellSPU/SPUAsmPrinter.cpp lib/Target/Sparc/SparcAsmPrinter.cpp lib/Target/MBlaze/MBlazeAsmPrinter.cpp lib/Target/Mips/MipsAsmPrinter.cpp MSP430 isn't represented because it did not even run with the long existing 'c' modifier and it was not apparent what needs to be done to get it inline asm ready.

2012-06-22Functions calling __builtin_eh_return must have a frame pointer.Jakob Stoklund Olesen
The code in X86TargetLowering::LowerEH_RETURN() assumes that a frame pointer exists, but the frame pointer was forced by the presence of llvm.eh.unwind.init which isn't guaranteed. If llvm.eh.unwind.init is actually required in functions calling eh.return (is it?), we should diagnose that instead of emitting bad machine code. This should fix the dragonegg-x86_64-linux-gcc-4.6-test bot. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@158961 91177308-0d34-0410-b5e6-96231b3b80d8
2012-06-20Remove 'static' from inline functions defined in header files.Chandler Carruth
There is a pretty staggering amount of this in LLVM's header files, this is not all of the instances I'm afraid. These include all of the functions that (in my build) are used by a non-static inline (or external) function. Specifically, these issues were caught by the new '-Winternal-linkage-in-inline' warning. I'll try to just clean up the remainder of the clearly redundant "static inline" cases on functions (not methods!) defined within headers if I can do so in a reliable way. There were even several cases of a missing 'inline' altogether, or my personal favorite "static bool inline". Go figure. ;] git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@158800 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-19Move the support for using .init_array from ARM to the genericRafael Espindola
TargetLoweringObjectFileELF. Use this to support it on X86. Unlike ARM, on X86 it is not easy to find out if .init_array should be used or not, so the decision is made via TargetOptions and defaults to off.

2012-06-18Temporarily revert r158087.Chandler Carruth
This patch causes problems when both dynamic stack realignment and dynamic allocas combine in the same function. With this patch, we no longer build the epilog correctly, and silently restore registers from the wrong position in the stack. Thanks to Matt for tracking this down, and getting at least an initial test case to Chad. I'm going to try to check a variation of that test case in so we can easily track the fixes required. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@158654 91177308-0d34-0410-b5e6-96231b3b80d8
