* | Fix ARM intrinsics-overflow.ll test on Windows | Reid Kleckner | 2014-05-09 | 1 | -1/+1 |
| | | | | | | | Windows on ARM only supports thumb mode execution, so we have to explicitly pick some non-Windows OS to test ARM mode codegen. llvm-svn: 208448 | ||||
* | Add custom lowering for add/sub with overflow intrinsics to ARM | Louis Gerbarg | 2014-05-09 | 1 | -0/+57 |
This patch adds support to ARM for custom lowering of the llvm.{u|s}add.with.overflow.i32 intrinsics for i32/i64. This is particularly useful for handling idiomatic saturating math functions as generated by InstCombineCompare. Test cases included. rdar://14853450 llvm-svn: 208435 |
