If th= is is supposed to document a different list, it would be good if it explained = why. `clang --print-supported-cpus` gives a list on 14-stable though alphabetica= lly sorted and undescribed. `clang -mcpu=3D?` and `clang -mtune=3D?` fail to re= turn the same result contrary to what `man clang` says should happen. The meaning of CPUTYPE should be more clearly described and any changes better used with it specifically should be documented in that section. I presume CPUTYPE definitions should be provided in a conditional way so = that the next best supported choice can be chosen in case of ports calling diffe= rent compiler versions. If the document is an example, such an example would be = good to see. That inclusion is already visible in https://cgit.freebsd.org/src/tree/share/examples/etc/make.conf and should likely be backported. With `clang --print-supported-cpus` on 'Target: x86_64-unknown-freebsd14.= 0`, there are more differences (alphabetically sorted, not sorted by brand, rel= ease date or order of preference/features). make.conf's example changelog says it was last updated to clang12. Differences between compilers in ports and versions in each version's base should be checked if make.conf's examples f= or CPUTYPE is intended to match the base compiler. As an interesting note, `clang -print-targets` says x86-64 is the target,= but `clang --target=3Dx86-64-unknown-freebsd14.0 --print-supported-cpus` fails = until changed to 'x86_64'; this is true of -print-targets output from 11 to -deve= l. Similarly, `clang --target=3Dx86 --print-supported-cpus` has no supported t= argets while '--target=3Dx86_64' does. If there is no compatible targets, the outp= ut does not end itself with a newline; shell prompt is placed at the end of the output. Are these bugs that upstream should know of, are they FreeBSD speci= fic, or did I misunderstand their use and output? llvm versions used to follow --print-supported-cpus differences: llvm10-10.0.1_12 llvm11-11.0.1_9 (no change) llvm12-12.0.1_13 llvm13-13.0.1_7 (no change) llvm14-14.0.6_5 llvm15-15.0.7_10 (no change) llvm16-16.0.6_10 llvm17-17.0.6_5 (matches 14-stable base version output) llvm18-18.1.2 llvm-devel-19.0.d20240212_1 (no change) Differences for consideration (clang version suggesting change, '-#' means version that removed it)... x86_64: + atom (12) + atom_sse4_2 (17) + atom_sse4_2_movbe (17) + arrowlake (18) + arrowlake-s (18) + arrowlake_s (18) + barcelona (12) -
