Extended Description

Case in point: Benchmarks/Shootout-C++/lists:

GCC: 11.19 seconds
CBE: 7.10 seconds
LLC 67.95 seconds

The LLC generated program spends most of its time in setjmp.

Is this done for some targets? What's the status?

[lattner]

Currently, it is stalled. I'm hoping to return to it in a few weeks.

[llvmbot]

This is done for x86-linux. I'm not sure what the status of x86-darwin
and ppc is.

[lattner]

This seems done to me. Any remaining issues are target-specific bugs, not lack of the feature. Thanks!

I'm also removing Bug 1414 as a blocking dependency.
