| 31 ** dyncall thunks | |
| 32 ** | |
| 33 ** thunks are small-size hybrid code/data objects, created at run-time to | |
| 34 ** be used as function pointers with associated data and entry functions. | |
| 35 ** | |
| 36 ** The header contains code, that does load its address into a designated scratch | |
| 37 ** register and will jump to a thunk function. | |
| 38 ** | |
| 39 ** Thunk entry procedures are compiled functions, that are called as a result of | |
| 40 ** a thunk function. | |
| 41 ** There is one thunk entry currently for supporting callbacks. | |
| 42 ** | |
| 43 ** Thunk context register ( ::= an available scratch register in the calling convention): | |
| 44 ** | |
| 45 ** x86: eax | |
| 46 ** x64: rax | |
| 47 ** ppc: r2 | |
| 48 ** arm: r12 | |
| 49 ** arm64: x9 | |
| 101 | 50 ** mips: t4 |
