From 04edfa544210c1bbf3ecf4702a66a99cbd9f3ca0 Mon Sep 17 00:00:00 2001 From: Dylan McKay Date: Thu, 28 Sep 2017 06:16:45 +0000 Subject: Merging r314179: ------------------------------------------------------------------------ r314179 | dylanmckay | 2017-09-26 13:45:27 +1300 (Tue, 26 Sep 2017) | 11 lines [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. ------------------------------------------------------------------------ git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_50@314379 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Target/AVR/AVRTargetMachine.cpp | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/lib/Target/AVR/AVRTargetMachine.cpp b/lib/Target/AVR/AVRTargetMachine.cpp index a9d61ffc952c..e698b6e694cf 100644 --- a/lib/Target/AVR/AVRTargetMachine.cpp +++ b/lib/Target/AVR/AVRTargetMachine.cpp @@ -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) { -- cgit v1.2.3
