One goal is to have dmd use the g++ exception handling mechanism. But googling how that works, I find dead links, specs that are 15 years old accompanied by vague comments about it being "extended" and "look at the g++ source code", etc.On 9/23/2014 11:03 AM, David Nadlinger wrote:

Is anyone fluent with libunwind?
More or less.
What exactly are your goals? I thought the options we have are fairly clear, as
discussed a few days ago. At least, Amaury and I seemed to agree (both of us
worked on EH recently). The main question to decide is whether you want to go
down the catch-C++-exceptions-in-D rabbit hole.
Are there any actual docs about how it works for x86? Or is it the usual "take apart the output of g++ and figure it out" that I usually wind up doing :-( ?
