[Qemu-devel] [PATCH v2 2/8] target-tricore: Add instructions of RR opcode format, that have 0xb as the first opcode |
|
Date: |
Wed, 17 Dec 2014 15:59:15 +0000 |
Add instructions of RR opcode format, that have 0xb as the first opcode.
Add helper functions, for hword and byte arithmetics:
* add_h_ssov/suov: Add two halfword and saturate on overflow.
* sub_h_ssov/suov: Sub two halfword and saturate on overflow.
* absdif_h_ssov: Compute absolute difference for halfwords and saturate on
overflow.
* abs_h_ssov/suov: Compute absolute value for two halfwords and saturate on
overflow.
* abs_b/h: Compute absolute value for four/two bytes/halfwords
* absdif_b/h: Compute absolute difference for four/two bytes/halfwords
* add_b/h: Add four/two bytes/halfwords.
* sub_b/h: Sub four/two bytes/halfwords.
* eq_b/h: Compare four/two bytes/halfwords with four/two bytes/halfwords on
equality and set all bits of to either one ore zero.
* eqany_b/h: Compare four/two bytes/halfwords with four/two bytes/halfwords
on equality.
* lt_b/bu/h/hu: Compare four/two bytes/halfwords with four/two
bytes/halfwords
on less than signed and unsigned.
* max_b/bu/h/hu: Calculate max for four/two bytes/halfwords signed and
unsigned.
* min_b/bu/h/hu: Calculate min for four/two bytes/halfwords signed and
unsigned.
Add helper function abs_ssov, that computes the absolute value for a 32 bit
integer and saturates on overflow.
Add microcode generator functions:
* gen_sub_CC: Caluclates sub and sets the carry bit.
* gen_subc_CC: Caluclates sub and carry and sets the carry bit
* gen_abs: Compute absolute value for a 32 bit integer.
* gen_cond_w: Compares two 32 bit values on cond and sets result either
zero or all bits one.
OPC2_32_RR_MIN switched with OPC2_32_RR_MIN_U.
Signed-off-by: Bastian Koppelmann <address@hidden>
---
v1 -> v2:
- gen_cond_w now uses neg and saves a temp.
- SSOV16/SUOV16 are now regular functions.
- Use TCG_CALL_NO_RWG_SE for all helpers not using globals.
