__float128 is not supported on Apple Silicon #473

Closed Season0518 closed 1 year ago

Season0518 commented 1 year ago

Hello, I recently wrote some algorithm problems using Macbook on the M2Max chip. When I use the bits/stdc++ header file, the header file displays: In included file: __float128 is not supported on this target . But the program can be compiled normally. Is this a BUG or am I using it inappropriately?

For a clearer description of the problem, here are my simplified directory structure and screenshots:

Can you build the program successfully with clang as the compiler, or only with gcc?

Season0518 commented 1 year ago

Could you please tell me what exactly it means? Is it compiled with g++/clang under the command line? Or run with CMake? On the command line, it can also be compiled normally. ScreenShot:

The screenshot shows compiling and running with the corresponding toolchain

HighCommander4 commented 1 year ago

Does clang++ main.cpp work?

Season0518 commented 1 year ago

Yes,Because there is no bits/stdc++ header file under clang++, I replaced it with the header file that reported the error. The error persists, but compiles fine

image image

Update: Both clangd and clang++ come from llvm

HighCommander4 commented 1 year ago

Can you try keeping <bits/stdc++.h> but running clang with with clang++ -std=libstdc++ main.cpp?

This is a closer approximation to how clangd is trying to parse the code.

Season0518 commented 1 year ago

I tried but it doesn't work

image
HighCommander4 commented 1 year ago

My bad, I made a mistake with the flag: I meant -stdlib=libstdc++ rather than -std=libstdc++.

Season0518 commented 1 year ago

It doesn't matter, it's prompting like this now

image
HighCommander4 commented 1 year ago

Ok, I see, clang doesn't know about your libstdc++ installation. Clangd is able to find it due to the --query-driver.

Let's try a different approach. Let's take the command that clangd prints in the log:

/opt/homebrew/Cellar/gcc/12.2.0/bin/aarch64-apple-darwin22-g++-12 --target=aarch64-apple-darwin22 --driver-mode=g++ -g -arch arm64 -isysroot /Library/Developer/CommandLineTools/SDKs/MacOSX13.3.sdk -o CMakeFiles/ACM_Env.dir/main.cpp.o -c -isystem /opt/homebrew/Cellar/gcc/12.2.0/bin/../lib/gcc/current/gcc/aarch64-apple-darwin22/12/../../../../../../include/c++/12 -isystem /opt/homebrew/Cellar/gcc/12.2.0/bin/../lib/gcc/current/gcc/aarch64-apple-darwin22/12/../../../../../../include/c++/12/aarch64-apple-darwin22 -isystem /opt/homebrew/Cellar/gcc/12.2.0/bin/../lib/gcc/current/gcc/aarch64-apple-darwin22/12/../../../../../../include/c++/12/backward -isystem /opt/homebrew/Cellar/gcc/12.2.0/bin/../lib/gcc/current/gcc/aarch64-apple-darwin22/12/include -isystem /opt/homebrew/Cellar/gcc/12.2.0/bin/../lib/gcc/current/gcc/aarch64-apple-darwin22/12/include-fixed -isystem /Library/Developer/CommandLineTools/SDKs/MacOSX13.3.sdk/usr/include -isystem /Library/Developer/CommandLineTools/SDKs/MacOSX13.3.sdk/System/Library/Frameworks -resource-dir=/opt/homebrew/Cellar/llvm/16.0.0/lib/clang/16 -- /Users/vm/test_cpp/main.cpp

and replace the compiler with clang++ as well as removing some of the stuff clangd adds that's not suitable for running on the command line to get:

clang++ --target=aarch64-apple-darwin22 -g -arch arm64 -isysroot /Library/Developer/CommandLineTools/SDKs/MacOSX13.3.sdk -o CMakeFiles/ACM_Env.dir/main.cpp.o -c -isystem /opt/homebrew/Cellar/gcc/12.2.0/bin/../lib/gcc/current/gcc/aarch64-apple-darwin22/12/../../../../../../include/c++/12 -isystem /opt/homebrew/Cellar/gcc/12.2.0/bin/../lib/gcc/current/gcc/aarch64-apple-darwin22/12/../../../../../../include/c++/12/aarch64-apple-darwin22 -isystem /opt/homebrew/Cellar/gcc/12.2.0/bin/../lib/gcc/current/gcc/aarch64-apple-darwin22/12/../../../../../../include/c++/12/backward -isystem /opt/homebrew/Cellar/gcc/12.2.0/bin/../lib/gcc/current/gcc/aarch64-apple-darwin22/12/include -isystem /opt/homebrew/Cellar/gcc/12.2.0/bin/../lib/gcc/current/gcc/aarch64-apple-darwin22/12/include-fixed -isystem /Library/Developer/CommandLineTools/SDKs/MacOSX13.3.sdk/usr/include -isystem /Library/Developer/CommandLineTools/SDKs/MacOSX13.3.sdk/System/Library/Frameworks -- /Users/vm/test_cpp/main.cpp

What happens if you run that?

Season0518 commented 1 year ago

Ok, I first executed it in the main.cpp directory, and he prompted an error,

image

and then I navigated to the build directory to find the .o file, and he prompted like this

image
HighCommander4 commented 1 year ago

Ok, so this indicates the issue is not specific to clangd, but rather clang itself doesn't support this type (__float128).

Since clangd uses clang's parser, it's constrained to parsing code that clang can understand. In cases of projects normally compiled with gcc, this generally means making the code portable enough that clang can also compile it.

I'm not sure how to do that in this particular case, but as the question is now no longer clangd-specific (it's "how to get clang to accept this code"), hopefully you can find an answer to that elsewhere.

Season0518 commented 1 year ago

Ok, then I will disable this error in the configuration file of clangd using the “type_unsupported” option, sincerely thank you for your quick reply

Attaching my clangd config so others can solve this problem
