[libunwind] _ReadSLEB and _ReadULEB

[Tommy Hoffner]

Whats the story behind _ReadSLEB and _ReadULEB?

I spent quite a lot of time locating a bug where the personality routine got in 
to an endless loop. Finally I fixed it by removing the two mentioned routines 
from the libunwind library (so it used the libipr versions instead)..

I'm using the latest ICC 8.1 with accompanying libipr together with libunwind 
0.98.3.

I tried to see if there was any support in the distribution for controlling 
whether you want these in or not (there is some mentioning about them having 
something to do with a compability-bug in icc 8.0), but I didn't find any way 
apart from manually updating the Makefiles.

What is the plan for future releases. I would expect that the number of users 
running the ICC 8.0 compiler is steadily decreasing, so adding them should 
probably be optional, not removing them.

PS
My program contained two exeptions and two catch clauses. One, that was 
unwinding through dynamically generated code, worked. the other one didn't.
My personal suspicion is that the lexically first ocurring worked and the other 
didn't, but I haven't verified since I got it working with the above solution.
