* | ARM: introduce llvm.arm.undefined intrinsic | Saleem Abdulrasool | 2014-05-22 | 1 | -0/+14 |
This intrinsic permits the emission of platform specific undefined sequences. ARM has reserved the 0xde opcode which takes a single integer parameter (ignored by the CPU). This permits the operating system to implement custom behaviour on this trap. The llvm.arm.undefined intrinsic is meant to provide a means for generating the target specific behaviour from the frontend. This is particularly useful for Windows on ARM which has made use of a series of these special opcodes. llvm-svn: 209390 |
