Given the need for -mfp16-format=ieee (on some processors), you should be updating target-supports.exp:add_options_for_float16 to add that option in the ARM case, and make sure that the tests run in cases where the option is needed to enable support for this format. > That means making sure that only __fp16 promotes and adding similar hooks to > those used in the AArch64 port giving the excess precision rules, and > marking HFmode as supported in libgcc. Does "supported in libgcc" mean this patch completes fixing bug 63250? -- Joseph S. Myers jos...@codesourcery.com
