Add hwsync extended mnemonic.
|

|

|
|
|
2c2fa1 |
This commit adds a new extended menmonic for "sync 0" (same as "sync").
|
|
|
2c2fa1 |
The ISA documentation doesn't explicitly mention hwsync as an extended
|
|
|
2c2fa1 |
mnemonic (yet), but it does mention "heavyweight sync" and "hwsync" as
|
|
|
2c2fa1 |
the operation that gets performed when the sync's L field is 0.
|
|
|
2c2fa1 |
This is only enabled for POWER4 and later.
