https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=207599 --- Comment #2 from Kenneth Salerno <kennethsalerno@yahoo.com> --- (In reply to Mark Millard from comment #1) Thanks, Mark. I looked through the LLVM ticket and didn't find anything relevant to this issue on powerpc64 clang. Seems to be hanging at branch to counter register (when I compared to the asm generated by GCC, that code had instead a branch to link register). I even tried building the kernel modules with GCC where -mlongcall was needed and clang for everything else, though soft-float is a missing option in clang that I'm not sure is necessary or not. I noticed building with altivec support kills the kernel load even sooner so maybe soft-float is a necessary switch clang needs for powerpc64 to build a working kernel? -- You are receiving this mail because: You are the assignee for the bug.help
