* Remove an assertion to fix PR9872.Jakob Stoklund Olesen2011-05-082-1/+6
| | | | | | | | | | | | | | | | | | | | It can happen that a live debug variable is the last use of a sub-register, and the register allocator will pick a larger register class for the virtual register. If the allocated register doesn't support the sub-register index, just use %noreg for the debug variables instead of asserting. In PR9872, a debug variable ends up in the sub_8bit_hi part of a GR32_ABCD register. The register is split and one part is inflated to GR32 and assigned %ESI because there are no more normal uses of sub_8bit_hi. Since %ESI doesn't have that sub-register, substPhysReg asserted. Now it will simply insert a %noreg instead, and the debug variable will be marked unavailable in that range. We don't currently have a way of saying: !"value" is in bits 8-15 of %ESI, I don't know if DWARF even supports that. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@131073 91177308-0d34-0410-b5e6-96231b3b80d8
