I am trying to integrate some code from a colleague. This codes move a tremendous amount of data around. The C++ method at the center of current controversy uses a switch statement with roughly 3000 case statements. (I acknowledge that perhaps we need to rethink that C++ method.)
When I try to build the application in CCSv6.1.2 with C6000 CGTv7.4.14, the optimizer terminates abnormally.
We develop our software on an isolated network. Consequently, I must manually type what I see into this form.
I see messages something like this:
ERROR - OUT OF MEMORY - OPTIMIZER ABORTED IN
<module with large switch statement with a bunch of cases>
Optimizer terminated abnormally in function
<function with large switch statement>
in file
<file with large switch statement>.cpp
Compilation failure
gmake[1]: *** [<object>] Error 1
gmake[1]: Target 'main-build' not remade because of errors.
gmake: *** [all] Error 2
There are a few things I will try shortly:
- Reduce optimization level for the file with large switch statement
- Optimization level 1
- Optimization level 0
- Optimization off
- Try C6000 CGT v7.4.24 (Our application does not build with C6000 CGT v8.x. We have not needed to use C6000 CGT v8.x so far.)
- Try CCSv8.3.0 (It is the newest version available on our isolated network)
Any other suggestions?
Thanks in advance for guidance.
PJ
