[rvm-research] volatile registers

[Da F. <jvf...@ya...>]

Hello:
When will rvm save volatile registers except taking yieldpoints? Unpreemptible 
code can't have yield point, but I find that a parameter passed in from rdx 
seems to be removed of upper half on 64bit platform. This cause a SIGSEGV, as 
the value is used as index to address a object lock field.
