CCSTUDIO: CCS 20.3.1, Code highlighting with pre defined macro names doesn't work properly

Martin Wiche

Part Number: CCSTUDIO

Hi folks,

I was trying out some DSP functions and noticed that code highlighting with pre defined macro names doesn't work properly. First I though my DSP(TMU) setup (tmu on, fpu32, float relaxed) was not right and further tested. My code worked with CCS Theia 1.5.1, but doesn't seem to work with CCS 20.3.1 (Theia based) at first.

But after further testing disassambly shows the expected code lines, so DSP is working (but not the highlighting)!

Sadly, I found nohing (expect 8 year old posts) on the fly regarding this topic in this forum. So, if you stumble over my thread, don't get confused like myself.

Table 2-30 Predefined C28x Macro Names

Macro Name	Description
__DATE__⁽¹⁾	Expands to the compilation date in the form mmm dd yyyy
__FILE__⁽¹⁾	Expands to the current source filename
__LINE__⁽¹⁾	Expands to the current line number
__little_endian__	Always defined to 1.
__PTRDIFF_T_TYPE__	Set to the type of ptrdiff_t.

__TMS320C28XX_CLA0__	Defined to 1 if the --cla_support=cla0 option was used and the source file is a .cla file.
__TMS320C28XX_CLA1__	Defined to 1 if the --cla_support=cla1 option was used and the source file is a .cla file.

__TMS320C28XX_IDIV__	Defined to 1 if the --idiv_support=idiv0 option was used.
__TMS320C28XX_TMU__	Defined to 1 if the --tmu_support option was used with any setting.
__TMS320C28XX_TMU0__	Defined to 1 if the --tmu_support option was used with any setting.
__TMS320C28XX_TMU1__	Defined to 1 if the --tmu_support=tmu1 option was used.
__TMS320C28XX_VCU0__	Defined to 1 if the --vcu_support option was used with any setting.
__TMS320C28XX_VCU2__	Defined to 1 if the --vcu_support=vcu2 option was used.

Hi Martin,

My code worked with CCS Theia 1.5.1, but doesn't seem to work with CCS 20.3.1 (Theia based) at first.

Are you saying that the code highlighting worked in CCS Theia 1.5.1 but not CCS 20.3.1? Or did you just mean that you were trying to troubleshoot why your code is not working in 20.3.1 and this code highlighting issue led you astray?

I ask because I see the same exact issue in CCS Theia 1.5.1 and CCS 20.3.1.

Thanks

Hi Ki,

first thanks for checking and verfing the issue.

"Are you saying that the code highlighting worked in CCS Theia 1.5.1 but not CCS 20.3.1?

I ask because I see the same exact issue in CCS Theia 1.5.1 and CCS 20.3.1."

"Or did you just mean that you were trying to troubleshoot why your code is not working in 20.3.1 and this code highlighting issue led you astray?"

Second, you got me there, which made me thinking. So I checked once more with 1.5.1 Theia, and I can confirm, code highlighting doesn´t work there either with with pre defined macro names. To be honest, on Theia 1.5.1 i just tried out a simple "__sqrtf()" instruction, glanced at the headers and thought the pre defined macros are working there. Then a colleague told me about CCS 20.3.1, installed and I switched to this IDE. There I tried if "sinf()" will be replaced with the TMU provided "__releaxed_sinf()". I added the #ifdef __TMS320C28XX_TMU__ around the sinf(). Thought at first my TMU setup was wrong and then tried out different things. The #warning TMU detected confirmerd it for me, TMU is working and something must be wrong with code highlighting.

In short: I was troubleshooting why my code seemed to be not working (Side note: Set optimization to 3 - Interprocedure and 5 - Speed made it more confusing too... my bad) and a not working code highlighting just made it more confusing.

Nevertheless, I´m now using 20.3.1 and the TMU ist working, but it would be nice if this issue could be fixed in the future.

Also I wanted to create this post, so someone with the same problem, can find a quick Google answer. ;-)

With best regards, Martin

I am pretty sure this is a known issue with a plan to fix. I'll need to confirm this.

The are a few known issues with the syntax highlighting, including this one. We are looking to address in a future release.
