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
50 **
