--- Comment #3 from Mark Millard <[email protected]> --- Below is what llvm-org's James Molloy reports about needing -mno-unaligned-access when building clang and clang++ for use in a SCTLR bit[1]==1 context: From: [email protected] Subject: [Bug 25958] FreeBSD 11.0-CURRENT clang++ 3.7.1 gets Bus Errors during compilation on arm that has SCTLR bit[1]==1 (alignment required) Date: December 28, 2015 at 1:28:28 PM PST To: <[email protected]> James Molloy changed bug 25958 What Removed Added CC [email protected] Comment # 2 on bug 25958 from James Molloy Hi Mark, Thanks for raising this. Before checking the specifics of what you found - did you compile Clang with -mno-unaligned-access? We will by default compile assuming SCTLR.A is 0. -mno-unaligned-access switches this assumption off and enables strict alignment mode. Cheers, James More notes: I've answered with the example compilation command for the specific clang source file, extracted from a script log of my build: I had used -mno-unaligned-access. -- You are receiving this mail because: You are the assignee for the bug. _______________________________________________ [email protected] mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-bugs To unsubscribe, send any mail to "[email protected]"
