https://gcc.gnu.org/bugzilla/show_bug.cgi?id=117089 --- Comment #1 from Ryan --- This can likely be closed. AARCH64 / ARM64 has a similar issue. Instead of every 10th file causing a crash, it's every 1000th for that arch. So it appeared to build fine last night, by luck, then this morning it se

[Bug middle-end/116299] GCC optimizes away code when long double is represented by the IBM double-double method.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=116299 --- Comment #8 from Ryan --- The assembly generated on godbolt for ppc64el is indeed different with the "volatile" included. It may be the default that -O3 is supposed to aggressively optimize this away, but the spltting trick works for architec
