 // In quick code for ARM and MIPS we make poor use of registers and perform frequent suspend
 // checks in the event of loop back edges. The SUSPEND_CHECK_INTERVAL constant is loaded into a
 // register at the point of an up-call or after handling a suspend check. It reduces the number of
 // loads of the TLS suspend check value by the given amount (turning it into a decrement and compare
 // of a register). This increases the time for a thread to respond to requests from GC and the
 // debugger, damaging GC performance and creating other unwanted artifacts. For example, this count
 // has the effect of making loops and Java code look cold in profilers, where the count is reset
 // impacts where samples will occur. Reducing the count as much as possible improves profiler
