[libcxx][libc] Hand in Hand PoC with from_chars (#91651) Implements std::from_chars for float and double. The implementation uses LLVM-libc to do the real parsing. Since this is the first time libc++ uses LLVM-libc there is a bit of additional infrastructure code. The patch is based on the [RFC] Project Hand In Hand (LLVM-libc/libc++ code sharing) https://discourse.llvm.org/t/rfc-project-hand-in-hand-llvm-libc-libc-code-sharing/77701 2024-10-21 15:04:06 -07:00			`#===--------------------------------------------------------------------===//`

[Offload] Use libc 'hand-in-hand' module to find RPC header (#117928) Summary: We should now use the official™ way to include the files from `libc/shared`. This required some code to make sure that it's not included twice if multiple people use it as well as a sanity check on the directory. 2024-11-27 20:14:13 -06:00			`if(NOT TARGET llvm-libc-common-utilities)`
[cmake] Move FindLibcCommonUtils to shared cmake, to fix standalone builds (#131586) Move `FindLibcCommonUtils` from LLVM's CMake module directory to the shared top-level CMake directory, as the module is intended to be used from within the source tree rather than the installed LLVM version. This fixes standalone offload builds after #131205. 2025-03-17 14:00:09 +01:00			`set(libc_path ${CMAKE_CURRENT_LIST_DIR}/../../libc)`
