I was reminded about this from a comment on the list, where
a new developer had gotten confused by our backtrace.
Changes from V1 to V2:
* Rebase to master.
* Do not try to allocate the ELF stuff within the code_gen_buffer.
Instead we can use a SHT_NOBITS trick to say that's out-of-line.
* Use C structures (with alignment and packing annotations) to create
the Dwarf2 unwind info. Previously I had used inline assembly.
Example:
Breakpoint 1, helper_idivl_EAX (t0=512)
at /home/rth/work/qemu/qemu/target-i386/op_helper.c:1882
1882 {
