Tool/software: TI C/C++ Compiler
When updating the compiler in my project to v18.1.1.LTS, the call to the intrinsic __delay_cycles() results in an unresolved reference compilation error.
Changing the compiler back to v16.9.7.LTS and the project compiles fine.
I am unable to reproduce this problem. For the source file which contains the call to __delay_cycles, please send in a test case as described in the article How to Submit a Compiler Test Case.
Thanks and regards,
-George
Simply creating a "hello world" project and adding a call to __delay_cycles() showed the problem on my system.
Also verified that a peer's development system showed the same problem.
Preprocessed source file attached.
CCS version: 7.3.0.00019
TI Compiler: 18.1.1.LTS
Processor: TMS570LC43xx

* succeeding from empirical or other `hard' evidence, don't

*
* * These are meant to be used in places that are run `a lot'.
* It is wasteful to make predictions in code that is run
* seldomly (e.g. at subsystem initialization time) as the

We're using the TMS570LC4357 MCU, which is an ARM Cortex-R5 processor. I haven't found anything in the TI documentation which specifies it, but ARM's Technical Reference Manual specifies Cortex-R5s as implementing the ARMv7-R architecture.
With the project we set up using the CCS wizard it has us compiling using the "-mv7R5" option to the compiler, but is not specifying any --silicon_version option. My understanding is that -mv is an alias to --silicon_version, and that there's no need to use both options.
I assume that it would be unwise for us to specify 7R4 to either -mv or to --silicon_version.
Table 5-3 ARM Intrinsic Support by Target specifies that __delay_cycles() is supported for ARM V7R (Cortex-R4). It doesn't explicitly say anything about Cortex-R5 one way or another. However, as above, I believe Cortex-R5 _is_ an ARM V7R.
v16.9.6 and v16.9.7 both compile __delay_cycles() when -mv7R5 is specified.
Is there a reason that v18.1.1 does not support __delay_cycles() for -mv7R5?

I don't know. So, I filed CODEGEN-4692 in the SDOWP system. It says not supporting __delay_cycles for Cortex-R5 is a bug. If that is wrong, then this is one way to find out. You are welcome to follow it with the SDOWP link below in my signature.
Thanks and regards,

Unfortunately, it is still in the just filed state. I am looking into it. I am confident I can get it moving. I apologize for the delay.
Thanks and regards,
