--- Comment #11 from A. Wilcox (awilfox) <awilfox at adelielinux dot org> --- I was unable to find any target-specific code in libquadmath at all. I haven't bothered to actually bisect this, but the 13 branch is the last one that builds libquadmath without the compiler supporting TF mode emulation. And it can't seem to do that any more without ldbl128 support. Passing --disable-libquadmath --disable-libquadmath-support enables GCC 14 and trunk to build correctly on my system.
