Thanks.

Some more tests:

test 1:

if (){
  vadd (integer RVV intrinsic)
}else{
  CALL
}
vfadd static
return

test 2:

if (){
  vfadd DYN
}else{
  CALL
}
vfadd static
return

test 3:

if (){
  vfadd static
}else{
  CALL
}
vfadd static
return

I think that's enough, no more tests.

Subject: [PATCH v3] RISC-V: Support CALL for RVV floating-point dynamic rounding
From: Pan Li <pan2.li@intel.com>
 
In basic dynamic rounding mode, we simply ignore call instructions and
we would like to take care of call in this PATCH.
 
During the call, the frm may be updated or keep as is. Thus, we must
make sure at least 2 things.
 
1. The static frm before call should not pollute the frm value in call.
2. The updated frm value in call should be sticky after call completed.
 
We will perfrom some steps to make above happen.
 
1. Mark call instruction with new mode DYN_CALL.
2. Mark the instruction after CALL from NONE to DYN.
3. When emit for a DYN_CALL, we will restore the frm value.
4. When emit from a DYN_CALL, we will backup the frm value.
 
Let's take a flow for this.
 
           +-------------+
           | Entry (DYN) | <- frrm a5
           +-------------+
          /               \
    +-------+             +-----------+
    | VFADD |             | VFADD RTZ |  <- fsrmi 1(RTZ)
    +-------+             +-----------+
          |                    |
    +-------+             +-----------+
    | CALL  |             | CALL      |  <- fsrm a5
    +-------+             +-----------+
          |                       |
+-----------+                 +-------+
| SHIFT     | <- frrm a5      | VFADD |  <- frrm a5
+-----------+                 +-------+
          |                  /
+-----------+               /
| VFADD RUP | <- fsrm1 3(RUP)
+-----------+             /
           \             /
            +-----------------+
            | Exit (DYN_EXIT) | <- fsrm a5
            +-----------------+
 
Please *NOTE* some corn cases like no instruction after a call is not
well handled, and will be coverred in another PATCH(s) soon.
