Compiler not building in release mode for 674x.

Yaels Steinsaltz

I have a function that does a lot of double multiplication, some adds and subtracts and reads from a staructure, nothing else.

It builds fine in debugging mode for all our platforms, and builds in release mode for the C64x+ and C66, but it hangs for the C674x. The compiler version I use is 7.3.17, but it was tried in other versions as well.

Is this a known problem? What is the work around? (other than replacing the hardware).

It's nearly impossible to determine that without a reproducible test case. Perhaps you can narrow it down for us a bit:

What command line options are you using?
Does it complete normally if you change the optimization level to -o1?
Does it complete normally if you disable software pipelining (--disable_software_pipeline)?

Our default make is -o2, but it doesn't complete normally with -o1. It is problematic for me to use --disable_software_pipeline with our make system, so I could not verify this.

I have created a stand alone function that shows this problem, and will be happy to send it over private channel, as our company has NDA with TI, but not attached in open to the public forum.

Using less than -o2 precludes software pipelining, so there's no need to check it.

This does not sound like the typical problem with slow compilation. I'll need to see a test case. I'll start a private conversation.

There seems to be a problem with the link you sent for the channel:
