Ok, I'm going to explain, because you asked so nice.
#define _SEH_emit_begintry() \
asm volatile (".cfi_escape 0x1c");
This will emit a user defined cfi code in the .eh_frame section. Current
offset from function start can be parsed.
The data will be parsed together with gcc generated unwind info and
converted into RUNTIME_FUNCTION, UNWIND_INFO, UNWIND_CODEs and
And of cause PSEH source level compatability is planned. Although I
might go for msvc source compatability and the create a common wrapper
if that works.
