GCC 12.0.1-2 Pre-release

[trashgod]

I installed GCC 12.0.1-2 Pre-release, seen here, on macOS 12.3/xcode-select version 2395 and modified the $PATH. Attempting to compile hello.adb, I get the following failure:

$ gprbuild hello
using project file /opt/gcc-12.0.1-2/share/gpr/_default.gpr
Compile
   [Ada]          hello.adb
clang (LLVM option parsing): Unknown command line argument '-x86-pad-for-align=false'.  Try: 'clang (LLVM option parsing) --help'
clang (LLVM option parsing): Did you mean '--x86-slh-loads=false'?
gprbuild: *** compilation phase failed

I see the similar output from gnatmake hello. Curiously, I see a similar result from gcc hello.c, although the same program compiles and runs with Apple clang version 12.0.0. Any guidance welcomed.

I’m using clang 13.1.6 on my Intel machine, and see that exact switch being used & accepted.

$ clang --version
Apple clang version 13.1.6 (clang-1316.0.21.2)
Target: x86_64-apple-darwin21.3.0
Thread model: posix
InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin

I found that the Command Line Tools weren’t getting updated, deleted /Library/Developer/CommandLineTools and re-ran xcode-select --install. Could this have something to do with it?

That resolved the issue; thank you. I misinterpreted the xcode-select -version: it's the version of xcode-select itself, not the installed libraries and tools.

$ xcode-select -version
xcode-select version 2395.
