[fuzzer] fix clang-cl build fuzzer lit test failure (#112339) The `check-fuzzer` runs fine with cl build llvm, but the following lit tests fail with clang-cl build llvm ``` ******************** Timed Out Tests (2): libFuzzer-x86_64-default-Windows :: fork-ubsan.test libFuzzer-x86_64-default-Windows :: fuzzer-oom.test ******************** Failed Tests (22): libFuzzer-x86_64-default-Windows :: acquire-crash-state.test libFuzzer-x86_64-default-Windows :: cross_over_copy.test libFuzzer-x86_64-default-Windows :: cross_over_insert.test libFuzzer-x86_64-default-Windows :: exit_on_src_pos.test libFuzzer-x86_64-default-Windows :: fuzzer-alignment-assumption.test libFuzzer-x86_64-default-Windows :: fuzzer-implicit-integer-sign-change.test libFuzzer-x86_64-default-Windows :: fuzzer-implicit-signed-integer-truncation-or-sign-change.test libFuzzer-x86_64-default-Windows :: fuzzer-implicit-signed-integer-truncation.test libFuzzer-x86_64-default-Windows :: fuzzer-implicit-unsigned-integer-truncation.test libFuzzer-x86_64-default-Windows :: fuzzer-printcovpcs.test libFuzzer-x86_64-default-Windows :: fuzzer-timeout.test libFuzzer-x86_64-default-Windows :: fuzzer-ubsan.test libFuzzer-x86_64-default-Windows :: minimize_crash.test libFuzzer-x86_64-default-Windows :: minimize_two_crashes.test libFuzzer-x86_64-default-Windows :: null-deref-on-empty.test libFuzzer-x86_64-default-Windows :: null-deref.test libFuzzer-x86_64-default-Windows :: print-func.test libFuzzer-x86_64-default-Windows :: stack-overflow-with-asan.test libFuzzer-x86_64-default-Windows :: trace-malloc-2.test libFuzzer-x86_64-default-Windows :: trace-malloc-unbalanced.test libFuzzer-x86_64-default-Windows :: trace-malloc.test ``` The related commits are https://github.com/llvm/llvm-project/commit/53a81d4d26f0409de8a0655d7af90f2bea222a12 and https://github.com/llvm/llvm-project/commit/e31efd8f6fbc27000a4933f889e0deb922411006. Following the change in https://github.com/llvm/llvm-project/commit/e31efd8f6fbc27000a4933f889e0deb922411006 can fix these failures. As for the issue mentioned in the comment that alternatename support in clang not good enough(https://bugs.llvm.org/show_bug.cgi?id=40218). I find that using `__builtin_function_start(func)` instead of directly using `func` would make it work as intended.
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.
Consult the Getting Started with LLVM page for information on building and running LLVM.
For information on how to contribute to the LLVM project, please take a look at the Contributing to LLVM guide.
