Issue_req.id not updating and missing commit_valid

Component

Issues in the RTL

Steps to Reproduce

Git hash: b66765a

Hello,

In the same setup as issue #800 , the id of the instruction through the issue_req interface is not updating (is always 0) and therefore the second time an instruction is offloaded, it gets stuck waiting for a commit_valid that never arrives.

I'm running this snippet of code, where it gets stuck after the issue of the second load instruction:

Firstly there is a random offloading that gets killed instantly:

Then the first load instruction offloads and has to wait for the mem_ready:

Then the mem_ready arrives, the instruction completes, and the second load is issued. However, the commit_valid for this second instruction never arrives because (I presume) the id is the same as the previous ones:

I attach a VDC dump of the execution.

Thanks!

Note that #825 was closed but its proposed fix has not been merged yet

Correct, the closing of the PR was an unintended side-effect, sorry about that @Silabs-ArjanB
