Stephen Williams 561564065d deal with mixed nested index directions. 2014-12-05 10:43:39 -08:00
Stephen Williams 409f8c5823 Add the vec4 %subi instruction 2014-12-05 09:45:29 -08:00
Stephen Williams 03198356a5 vec4-stack stack manipulation improvements. 2014-12-04 17:15:27 -08:00
Stephen Williams b1d2393789 Optimize the %sub instruction by integrating it with vvp_vector4_t class 2014-12-04 17:01:16 -08:00
Stephen Williams 0f740289e9 Optimize %mul instructions by integrating with vvp_vector4_t class. 2014-12-04 16:00:57 -08:00
Stephen Williams 46ce236cfb Optimize the %add and %addi instructions 
Tightly integrate with the vvp_vector4_t class to get much
better add performance.
 2014-12-04 12:38:08 -08:00
Stephen Williams 86139c855d Optimize the vec4-stack %cmp/s and %cmpi/s instructions. 
Magnitude compare is called a LOT, so it is worth putting some
special effort into it.
 2014-12-04 10:42:48 -08:00
Stephen Williams eb070b061b Optimize the vec4_to_index, which implements %ix/vec4 instructions. 2014-12-03 17:53:45 -08:00
Stephen Williams 2b1393e7b9 Reduce some vector copies in %load/vec4 and %concat/vec4 instructions. 
By clever stack manipulations, we can eliminate some vector copies,
which can improve performance.
 2014-12-03 13:12:06 -08:00
Stephen Williams 85c7b07a9b Implement %cmp/ne and %cmpi/ne 
These pull in the inversion of the output flags so that they more
efficiently implement != and !==, without %flag_inv instructions.

Stephen Williams 0c5ed2b60f Merge branch 'master' into vec4-stack 2014-12-03 08:36:38 -08:00
Stephen Williams 8fd1ead082 Revert "ivl: Allow to initialize variables with other variables (since Verilog-2001)." 
This reverts commit 610ca95cbe.
It turns out that the new feature is actually a bug.

Stephen Williams 1645e682f4 Generate more efficient vec4-stack code for real le compare. 2014-12-02 14:53:01 -08:00
Stephen Williams a57e0a1e3f vvp implementation of copy from vec4 to vec2 can use subarray method. 2014-12-02 14:52:37 -08:00
Stephen Williams b83144c552 The __vpiArray::set_word method should take a reference. 
Seem to have missed a case where a vvp_vector4_t can be passed by
const reference instead of by value.
 2014-12-02 13:02:46 -08:00
Stephen Williams 58fb80aec4 Implement and put to use the %muli instruction. 2014-12-02 12:46:17 -08:00
