Raw Normal View History

When printing MIR, output to errs() rather than outs(). Summary: Without this, this command $ llvm-run llc -stop-after machine-cp -o - <( echo '' ) outputs an error, because we close stdout twice -- once when closing the file opened for "-o", and again when closing outs(). Also clarify in the outs() definition that you can't ever call it if you want to open your own raw_fd_ostream on stdout.

StackMap: FastISel: Add an appropriate number of immediate operands to the frame setup instruction. This commit ensures that the stack map lowering code in FastISel adds an appropriate number of immediate operands to the frame setup instruction. The previous code added just one immediate operand, which was fine for a target like AArch64, but on X86 the ADJCALLSTACKDOWN64 instruction needs two explicit operands. This caused the machine verifier to report an error when the old code added just one. Reviewers: Juergen Ributzka Differential Revision: http://reviews.llvm.org/D11853 llvm-svn: 244508
