| * File: OP_INVOKE_STATIC.S |
| * |
| * Code: Call static direct method. Provides an "isrange" variable and |
| * a "routine" variable to specify this is the "range" version of |
| * invoke_static that allows up to 255 arguments. |
| * |
| * For: invoke-static, invoke-static/range |
| * |
| * Description: invoke-static is used to invoke static direct method. |
| * |
| * Format: B|A|op CCCC G|F|E|D (35c) |
| * AA|op BBBB CCCC (3rc) |
| * |
| * Syntax: [B=5] op {vD, vE, vF, vG, vA}, meth@CCCC (35c) |
| * [B=5] op {vD, vE, vF, vG, vA}, type@CCCC (35c) |
| * [B=4] op {vD, vE, vF, vG}, kind@CCCC (35c) |
| * [B=3] op {vD, vE, vF}, kind@CCCC (35c) |
| * [B=2] op {vD, vE}, kind@CCCC (35c) |
| * [B=1] op {vD}, kind@CCCC (35c) |
| * [B=0] op {}, kind@CCCC (35c) |
| * |
| * op {vCCCC .. vNNNN}, meth@BBBB (3rc) (where NNNN = CCCC+AA-1, that |
| * op {vCCCC .. vNNNN}, type@BBBB (3rc) is A determines the count 0..255, |
| * and C determines the first register) |
