[AVR] Use 1-byte alignment for all data types This was an oversight in the original backend data layout. The AVR architecture does not have the concept of unaligned loads - all loads/stores from all addresses are aligned to one byte. Discovered in avr-rust issue #64 https://github.com/avr-rust/rust/issues/64 Patch By Gergo Erdi. ------------------------------------------------------------------------ Modified: llvm/branches/release_50/lib/Target/AVR/AVRTargetMachine.cpp Modified: llvm/branches/release_50/lib/Target/AVR/AVRTargetMachine.cpp URL: http://llvm.org/viewvc/llvm-project/llvm/branches/release_50/lib/Target/AVR/AVRTargetMachine.cpp?rev=314379&r1=314378&r2=314379&view=diff ============================================================================== --- llvm/branches/release_50/lib/Target/AVR/AVRTargetMachine.cpp (original) +++ llvm/branches/release_50/lib/Target/AVR/AVRTargetMachine.cpp Wed Sep 27 23:16:45 2017 @@ -25,7 +25,7 @@ namespace llvm { -static const char *AVRDataLayout = "e-p:16:16:16-i8:8:8-i16:16:16-i32:32:32-i64:64:64-f32:32:32-f64:64:64-n8"; +static const char *AVRDataLayout = "e-p:16:8-i8:8-i16:8-i32:8-i64:8-f32:8-f64:8-n8-a:8"; /// Processes a CPU name. static StringRef getCPU(StringRef CPU) { _______________________________________________ llvm-branch-commits mailing list llvm-branch-commits@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/llvm-branch-commits
