mbed-os-example-wifi example, linker error:

Link: mbed-os-example-wifi
[Warning] @0,0: L3912W: Option 'legacyalign' is deprecated.

[ERROR] Warning: L3912W: Option 'legacyalign' is deprecated.

I can't find artifacts for the job adding this target in #9221 .

@ARMmbed/mbed-os-psa Would you be able to help to reproduce this and report to the ARMC6 team if this is valid internal fault (small chance this could be our setup fault).

I am using latest master as it is today.

armclang --version
Product: ARM Compiler 6.11 Professional
Component: ARM Compiler 6.11
Tool: armclang [5d3b4200]

[0xc0170]

cc @ARMmbed/mbed-os-test - Can you help us to reproduce this issue?

My version of ARMCC is : 6.11

[kimlep01]

I can reproduce the same error with Ubuntu 16 but in Windows the example compiles without issues. Toolchain version in Ubuntu:

armclang --version
Product: ARM Compiler 6.11 Professional
Component: ARM Compiler 6.11
Tool: armclang [5d3b4200]

[0xc0170]

@kimlep01 Thanks ! that would explain why I can't - I am on windows machine currently.

@ARMmbed/mbed-os-test Can we share this failure with details to the compiler team ? Please do.

@0xc0170 @kimlep01 It looks like the issue is fixed in 6.12. I just built mbed-os-example-wifi using mbed compile -m ARM_MUSCA_A1_NS -t ARM and it builds successfully.

OS: Ubuntu 16
Product: ARM Compiler 6.12 Ultimate
Component: ARM Compiler 6.12
Tool: armclang [5d624a00]

[0xc0170]

Great, we will update to 6.12 in the upcoming days. Hopefully we can close this one with an update!
