Summary Fix bit rot in ARMv7 JIT probe mechanism
Mark Lam
Reported 2014-04-03 10:09:44 PDT
This is just to get the ARMv7 JIT probe mechanism working again. The needed changes: 1. The macro assembler does not support pushing the SP register. Worked around this by pushing the LR register as a placeholder, and then writing the original SP value to that slot. 2. The CPUState field in the ProbeContext needs to be aligned on a 4 byte boundary, not an 8 byte boundary.
