/******************************************************************** |
|
| 2 |
Flush register windows on sparc. |
|
| 3 | ||
| 4 |
This function is in a separate file to prevent inlining. The "flushw" |
|
| 5 |
assembler instruction used on sparcv9 flushes all register windows |
|
| 6 |
except the current one, so if it is inlined, the current register |
|
| 7 |
window of the process executing the instruction will not be flushed |
|
| 8 |
correctly. |
|

See http://redmine.ruby-lang.org/issues/5244 for discussion. |
