Subject: [PATCH] tcg: Fix MAX_OPC_PARAM_IARGS
|
|
|
|
DEF_HELPER_FLAGS_5 was added some time ago without adjusting
|
|
MAX_OPC_PARAM_IARGS.
|
|
|
|
Fixing the definition becomes more important as QEMU is using
|
|
an increasing number of helper functions called with 5 arguments.
|
|
|
|
Add also a comment to avoid future problems when DEF_HELPER_FLAGS_6
|
|
will be added.
