ld64-241.9 gives a huge number of LTO remarks on stderr (!) when link LLVM bytecode objects: ld: LTO remark: <unknown>:0:0: system_error will not be inlined into main ld: LTO remark: <unknown>:0:0: system_fatal too costly to inline (cost=5, threshold=1) ld: LTO remark: <unknown>:0:0: system_fatal will not be inlined into main ld: LTO remark: <unknown>:0:0: strip_file too costly to inline (cost=230, threshold=225) ld: LTO remark: <unknown>:0:0: strip_file will not be inlined into main ld: LTO remark: <unknown>:0:0: strip_file too costly to inline (cost=230, threshold=225) ld: LTO remark: <unknown>:0:0: strip_file will not be inlined into main ld: LTO remark: <unknown>:0:0: fatal can be inlined into main with cost=195 (threshold=337) This can not be deactivated by the user. Example of linking ld64: "/Users/michael/nobak/gentoo/usr/bin/ld" -demangle -dynamic -arch x86_64 -macosx_version_min 10.10.0 -o ./strip.NEW -L../../ld64-241.9/src -L/Users/michael/nobak/gentoo/usr/lib/gcc/x86_64-apple-darwin14/4.2.1 ./strip.private.o -lprunetrie -lc++ -lSystem /Users/michael/nobak/gentoo/usr/bin/../lib/clang/3.5.1/lib/darwin/libclang_rt.osx.a -verbose_lto_remarks 2>&1 | wc -l 4274 Reproducible: Always
Created attachment 395430 [details, diff] add option -verbose_lto_remarks to ld64 to conditionally enable LTO remarks output
Thanks, I applied the patch
