Subject: RE: SJLJ-exceptions broken
1) I need to use sjlj exceptions because we dynamically generate code.
Since we do not have any means of generating the needed dwarf2 tables
dynamically because there is no API to do it, we can ONLY use
sjlj exception. All this is explained in a previous message.
2)
Our stack configuration looks like this:
C++ code
---------
dynamically generated code
---------
C++ code
---------
dynamically generated code
---------
C++ code <<<<<----- makes a throw
The problem is that since there isn't any dwarf2
info for the dynamically generated code, a throw will crash
when done in this configuration.
That is why we use that. Not because we are brain dead.
Thanks for your very useful comments but... yes, I repeat:
Not because we are brain dead but because we *need* to do this.
I can't send you any reproducing sources since I would need
to send our just in time compiler to you.
I use this in a toolchain "that now is mostly frozen" because the
"new and improved" toolchain will not compile our source code
since the bug PR 23167 still was unsolved last time I checked.

There are no platform details, no reproducing sources, and all this on a
toolchain that is now mostly frozen.
In addition, I also cannot tell why dwarf eh is not being used. So, the answer
the question, does anybody use SJLJ exceptions on linux is: no, not really.
Not unless the target is completely brain dead.
