commit r16-7355-g5bec884b2e890ffb950f1a3ccf325d92c3bf8496 Author: Jonathan Wakely <[email protected]> Date: Wed Jan 7 14:29:44 2026 +0000 libstdc++: Allow new-abi-baseline target to overwrite existing file There doesn't seem to be much benefit to writing the symbols to baseline_symbols.txt.new when an existing file is already present. It just adds a manual step for maintainers to move the .txt.new file to replace the .txt one. Overwriting the file directly allows you to use git diff to see what changed immediately, and you can easly use git commands to revert to the original file too. libstdc++-v3/ChangeLog: * testsuite/Makefile.am (new-abi-baseline): Overwrite existing file instead of creating baseline_symbols.txt.new. * testsuite/Makefile.in: Regenerate.
