Thanks for input. By seasoned you mean someone who has good knowledge of Mono
internals or generally a guy with low level experience on various
I slightly modified ASM generation
- wrapped .type and .size within .def/.endef directives
- removed local symbol emission
- removed underscore in front of global symbols
Now I can generate AOT images and runtime seems to find all data structures
it needs. In few first runs surprisingly some simple tests worked
successfully in aot and full-aot mode - console output, simple calculations,
events, catching exceptions, allocating bunch of objects and invoking
Then I regenerated AOT image of mscorlib and it doesn't work any more.
Trying to figure out issues now. In full-aot mode it crashes after a jump to
a non-executable memory region from function
The first few ops after the function prolog look like this (full function
asm here <http://pastebin.com/GfTLeN1e> ):
mov rcx,qword ptr [rbp-70h]
mov qword ptr [rbp-38h],rsp
The address loaded into rax looks very suspicios. As far I can see that
function is compiled from IL. Haven't tracked down were is it coming from?
Could someone point me to it? What is it attempting call internally?
