The LLVM code generator should only consume the serialized IR and not use any other VM functionality.
This CL adds a custom zone which can be used for the deserialized IR nodes and removes any
Dart_SetVMFlags/Dart_Initialize/ApiZone/... calls.
This works with the existing example:
% ninja -C out/ReleaseX64 codegen
% out/ReleaseX64/codegen runtime/llvm_codegen/test/codegen/Inputs/hello.sex
...
define void @"hello.dart::main"() {
B1:
%0 = call i8* @llvm.stacksave()
%1 = ptrtoint i8* %0 to i64
%2 = load i64, i64 addrspace(256)* inttoptr (i64 72 to i64 addrspace(256)*)
%3 = icmp ult i64 %1, %2
br i1 %3, label %4, label %5
...
ret void
}
...
