In ExpandFPLibCall, an assumption is made that all floating point libcalls that take integer arguments use unsigned integers. In the case of ldexp and frexp, this assumption is incorrect, leading to miscompilation and subsequent target-dependent incorrect operation. Indicate that ldexp and frexp utilize signed arguments in ExpandFPLibCall. Fixes #108904 Signed-off-by: Timothy Pearson <tpearson@solidsilicon.com> (cherry picked from commit 90c14748638f1e10e31173b145fdbb5c4529c922)
The LLVM Compiler Infrastructure
Welcome to the LLVM project!
This repository contains the source code for LLVM, a toolkit for the construction of highly optimized compilers, optimizers, and run-time environments.
The LLVM project has multiple components. The core of the project is itself called "LLVM". This contains all of the tools, libraries, and header files needed to process intermediate representations and convert them into object files. Tools include an assembler, disassembler, bitcode analyzer, and bitcode optimizer.
C-like languages use the Clang frontend. This component compiles C, C++, Objective-C, and Objective-C++ code into LLVM bitcode -- and from there into object files, using LLVM.
Other components include: the libc++ C++ standard library, the LLD linker, and more.
