similar to: [LLVMdev] __builtin_malloc, __builtin_calloc support in LLVM

Hi, Is "__builtin_malloc" function supported in LLVM...? I checked in "tools/clang/include/clang/Basic/Builtins.def", "tools/clang/lib/CodeGen/CGBuiltin.cpp" and couldn't find the implementation. Could anyone please comment about it. Thanks in advance, Viswa -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi LLVM developers, After Remove int_x86_sse2_psll_dq_bs and int_x86_sse2_psrl_dq_bs intrinsics. The builtins aren't used by clang. https://reviews.llvm.org/rL229069 there was no Intrinsic::x86_sse2_psrl_dq any more, then how to migrate: Function *F = Intrinsic::getDeclaration(TheModule, Intrinsic::x86_sse2_psrl_dq); Result = Builder.CreateCall(F,

Hello, I was implementing the llvm_any_type in my intrinsic def int_csa_xxx : Intrinsic<[llvm_any_ty], [llvm_i32_ty]>; as the following in its corresponding builtins in Builtins.def: BUILTIN(__builtin_xxx, "v.", "nt") the "t" was sufficient here to not perform any type checking. The type checking was handled in CGBuiltin.cpp. This was working until

After worked around the problem in SimplifyCFG.cpp (calling isCast() instead of comparing opcode), I hit another gcc crash for FunctionImport.cpp line 480, which I have no idea what's wrong with the code. "Luckily", I found gcc4.8.2 and gave it a try, both crashes are gone. *New problem though:* /llvm-clang-trunk/src/tools/clang/lib/CodeGen/CGBuiltin.cpp: In member function

Hi, For now no. But I will add this three builtins to CGBuiltin.cpp. If you want, you can be a reviewer of this change.

One of the issues the LLVMLinux project is having is with the use of named registers in the Linux kernel code. The kernel uses something like this in order to assign a C variable name to a register (one for each kernel arch). register unsigned long current_stack_pointer asm("esp"); clang doesn't allow this kind of thing which required a patch which less efficient: #define

Hi Everyone！ I am a newbie at llvm. So the question may be fundamental but difficult to me. I want to add an trinsics in x86 and make the following changes.I want that max_qb can find the max of two Integers and return it. In src/include/llvm/IR/Intrinsics.td : let TargetPrefix = "x86" in { def int_x86_max_qb: GCCBuiltin<"__builtin_x86_max_qb">,

There are a few places in llvm's generic codegen that refer to target specific intrinsics. This is bad layering and we shouldn't do it. It also means that if we don't build a target we still have to support all of it's intrinsics and other such annoyances. The main violator of this is InstCombineCalls - I'd like to push this into the targets, and just have a case that says

This patch adds EmitTypeAuxAttribute() function to CGDebugInfo, which allows other parts of clang issue auxiliary information through an enumeration type in Dwarf information. For example, by calling DI->EmitTypeAuxAttribute(type, "ID", 1234); We can get following information in dwarf: <1><3f>: Abbrev Number: 3 (DW_TAG_structure_type) <40> DW_AT_name

You'd add a declaration to include/llvm/IR/IntrinsicsXYZ.td (where XYZ is your target), and then you can select them with a normal pattern in your

This is the definition of BITCAST in include/llvm/CodeGen/ISDOpcodes.h: // BITCAST - This operator converts between integer, vector and FP // values, as if the value was stored to memory with one type and loaded // from the same address with the other type (or equivalently for vector // format conversions, etc).

If I do T.getArch() == xxx TLI.setUnavailable(LibFunc::copysign) then this works at generating a call instead of not being able to select the ISD::FCOPYSIGN, but I don't know why I don't need to do this for other LibFunc functions (such as floor, etc... these generate call just fine)?

GCCBuiltin just gives it a name for clang to lookup. Generally they match up with builtins that gcc also implements, but that's not a requirement. If you add a builtin with the same name to the builtin file in clang's include/clang/Basic/Builtins*.def then they will find each other. You can also just add a builtin to clang's builtin file and catch it in clang's

Hi Duncan and llvm developers, The attached patch makes the function return true if the conversion is between a vector and an integer of the same size. Please review when you have time.
