Bug 26545 reports that the "noinline" attribute does not prevent the result of a function to be "inlined" into the caller. The problem comes in fact from the Inter-Procedural Sparse Constant Propagation which propagates the return value into the caller. This patch fixes this problem by patching the function ...The LLVM compiler infrastructure project is a software development effort that provides a set of tools (collectively known as "LLVM") to compiler writers; in the common use, these tools supply large, pre-built pieces of a compiler's code generation infrastructure. 向LLVM IR中的指令添加元数据. 内容来源于 Stack Overflow,并遵循 CC BY-SA 3.0 许可协议进行翻译与使用. 回答 ( 1) 关注 ( 0) 查看 ( 659) 试图在转换通过后 (使用C++API)将元数据添加到LLVM中的指令中。. 我打算存储这些信息,供工具链中的另一个工具使用。. 关于这个我有 ...public DILexicalBlockFile CreateLexicalBlockFile(DIScope scope, DIFile file, uint discriminator) Parameters.

Note that this operation is not commutative - not only concretely (e.g. the destination module is modified, becoming the result) but abstractly (e.g. unused private globals in the source module do not appear in the result, but similar globals in the destination remain).Jan 08, 2017 · This is a 'vector' (really, a variable-sized array), optimized for the case when the array is small.

Despite the declared types, most of the functions provided operate only on branches of the type hierarchy. The declared parameter names are descriptive and specify which type is required. Additionally, each type hierarchy is ...namespace llvm; class GetElementPtrInst; class GetElementPtrInst Declaration class GetElementPtrInst : public Instruction { /* full declaration omitted */ };C++ source code API documentation for LLVM. 546 // Check for the special case where the same exact value is used for bothThis is similar to back when LLVM got integrated assembler support and Clang stopped launching a sub-process just to assemble its own output. It doesn't really change the external interface of the clang++, just makes it a bit more efficient internally. 13. Share. Report Save. level 2Oct 19, 2018 · Summary.
