--- Comment #4 from Andrew Pinski <pinskia at gcc dot gnu.org> --- I came across a related issue here: Take: https://gcc.gnu.org/onlinedocs/gcc-12.2.0/gccint/C_002b_002b-ABI.html The original section name was just C++-ABI but had a heading of C++ ABI parameters Now post sphinx, it is just C++ ABI parameters for both the section name and the heading: https://gcc.gnu.org/onlinedocs/gccint/target-macros/c%2B%2B-abi-parameters.html The file name definitely could just be C++-abi here since we are in the target macro section.
