Hi all,
I am trying to build TFM with IAR with TFM_FIH_PROFILE=HIGH and I am facing the issue with the FIH labels.
I see following errors: [ 98%] Linking C executable ../bin/tfm_s.axf Error[Li006]: duplicate definitions for "FIH_LABEL_FIH_CALL_END_46_1"; in "main.o(libtfm_spm.a)", and "tfm_hal_platform.o(libtfm_spm.a)" Error[Li006]: duplicate definitions for "FIH_LABEL_FIH_CALL_START_46_1"; in "main.o(libtfm_spm.a)", and "tfm_hal_platform.o(libtfm_spm.a)" Error[Li006]: duplicate definitions for "FIH_LABEL_FIH_CALL_END_35_0"; in "tfm_hal_platform.o(libtfm_spm.a)", and "platform_svc_handler.o(libtfm_spm.a)" Error[Li006]: duplicate definitions for "FIH_LABEL_FIH_CALL_START_35_0"; in "tfm_hal_platform.o(libtfm_spm.a)", and "platform_svc_handler.o(libtfm_spm.a)"
I did some investigations and I believe I know the root cause: Looks like __COUNTER__ for IAR is unique only for a translation unit (.c file) - thus when 2 files have FIH call in same line with the same number of FIH calls before - it creates a label which overlaps with labels in other file.
For example tfm_hal_platform.c in our case has first FIH CALL in line 46 (which creates label FIH_LABEL_FIH_CALL_END_46_1) but main.c in our code also has first FIH CALL in line 46 which also results in FIH_LABEL_FIH_CALL_END_46_1 label.
The question is - how can we solve this issue? Any ideas I can try?

We have this commit in our tee, but it does not solve the issue I described.
FYI - that commit is helpful as it solves other compile issues, but not the one I reported.

Hi Bohdan,
I don’t have access to a IAR compiler, it seems it might require to change this line:
https://git.trustedfirmware.org/plugins/gitiles/TF-M/trusted-firmware-m/+/re...
To prefix “FIH_LABEL …" with "LOCAL FIH_LABEL …"
Can you give it a try if possible and let me know?

So just to clarify, you might need to explicitly make the symbol local, so the macro would have to be modified to have something like:
“FIH_LABEL_ …” to “LOCAL FIH_LABEL_ ...\n FIH_LABEL_ ...”
Given that the label itself is computed attaching line and cnt, it looks like quite ugly eventually…

So I got access to a IAR manual and the issue is in fact that with our recent refactoring the IAR FIH_LABEL uses the “::” instead of a single “:” . That will make it a public symbol and will lead to clashes. We are going to discuss internally to double check if that was done intentionally and provide a patch early next week.

Hi Bohdan,
Does this help?

I am trying to build TFM with IAR with TFM_FIH_PROFILE=HIGH and I am facing the issue with the FIH labels.
I see following errors: [ 98%] Linking C executable ../bin/tfm_s.axf Error[Li006]: duplicate definitions for "FIH_LABEL_FIH_CALL_END_46_1"; in "main.o(libtfm_spm.a)", and "tfm_hal_platform.o(libtfm_spm.a)" Error[Li006]: duplicate definitions for "FIH_LABEL_FIH_CALL_START_46_1"; in "main.o(libtfm_spm.a)", and "tfm_hal_platform.o(libtfm_spm.a)" Error[Li006]: duplicate definitions for "FIH_LABEL_FIH_CALL_END_35_0"; in "tfm_hal_platform.o(libtfm_spm.a)", and "platform_svc_handler.o(libtfm_spm.a)" Error[Li006]: duplicate definitions for "FIH_LABEL_FIH_CALL_START_35_0"; in "tfm_hal_platform.o(libtfm_spm.a)", and "platform_svc_handler.o(libtfm_spm.a)"
I did some investigations and I believe I know the root cause: Looks like __COUNTER__ for IAR is unique only for a translation unit (.c file) - thus when 2 files have FIH call in same line with the same number of FIH calls before - it creates a label which overlaps with labels in other file.
For example tfm_hal_platform.c in our case has first FIH CALL in line 46 (which creates label FIH_LABEL_FIH_CALL_END_46_1) but main.c in our code also has first FIH CALL in line 46 which also results in FIH_LABEL_FIH_CALL_END_46_1 label.
The question is - how can we solve this issue? Any ideas I can try?

Hi Antonio,
I have updated original patch as well as created two new ones:
1. https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/44148 2. https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/45563 3. https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/45564
Please let me know if there is anything else needed from my side.

Hi Antonio,
Thanks for the suggestion - I have tried it and it works for us.
I have created a patch for this issue along side with few other IAR related fixes - see https://review.trustedfirmware.org/q/topic:%22iar-compatibility%22

So I got access to a IAR manual and the issue is in fact that with our recent refactoring the IAR FIH_LABEL uses the "::" instead of a single ":" . That will make it a public symbol and will lead to clashes. We are going to discuss internally to double check if that was done intentionally and provide a patch early next week.
Thanks, Antonio

"FIH_LABEL_ ..." to "LOCAL FIH_LABEL_ ...\n FIH_LABEL_ ..."
Given that the label itself is computed attaching line and cnt, it looks like quite ugly eventually...
Thanks,

I don't have access to a IAR compiler, it seems it might require to change this line:
https://git.trustedfirmware.org/plugins/gitiles/TF-M/trusted-firmware-m/+/re...
To prefix "FIH_LABEL ..." with "LOCAL FIH_LABEL ..."
Can you give it a try if possible and let me know?
