* vm_core.h (rb_thread_t): use 32-bit running_time_usnormal2017-05-071-2/+2
| | | | | | | | | | | | | | | | | | | | The current range based current values of: TIME_QUANTUM_USEC=100000 RUBY_THREAD_PRIORITY_MAX=3 RUBY_THREAD_PRIORITY_MIN=-3 Gives a range of 12500..800000, plenty enough for a 32-bit integer. Clamping this also reduces potential implementation bugs between 32-bit and 64-bit platforms. I may consider a further reduction to uint16_t in the future for M:N threading, but some users may want slightly larger time quantums. * vm_core.h (rb_thread_t): use 32-bit running_time_us git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@58591 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
