I tried using --disassembly, --asm and --S option in compiler setting but it's not working ?
Can someone help me to generate .asm file in DS5 for arm 6 compilers.

I am trying to migrate my source code compilation from armcc compiler v5.06 to armclang v6. And I see armclang errors out saying it can not recognize cp15 registers. It looks like there might be a change in armcc vs clang as how to declare the registers…
I want to migrate an older project into the ARM Compiler 6, but I am getting errors in the retarget.c

Hello,
I work in a project in the Rail Industry, where it was decided to use a qualified compiler to meet the safety standard (SIL2) according to EN50657.
In this project the compiler optimization plays a very important role, because time critical functions…
I'm using Keil uVision v5.29 and ARM compiler v6.13.1 (ArmClang). I was looking for a static code analyzer and found that Clang includes a static analyzer that is run with the --analyze option (see http://clang.llvm.org/docs/UsersManual.html). I added…
Hi
is there a way to force constant strings to be aligned on 4 byte boundary?
For example: createTask("Taskname");
I tried the linker option "OVERALIGN", but it just generates a warning.
Cheers
Hello,
I'm trying to follow the tutorial here (community.arm.com/.../develop-embedded-control-systems-efficiently-in-matlab-with-arm-models-and-compiler-integration) to run the Simulink example 'ArmCortexM_FM_pil_top' on an FVP of the Cortex-M4.…
Uninitialized variables is getting assigned to DATA section instead of BSS section in ARM Compiler 6.6.
How to resolve this other than placing the variable in .bss.<section_name>?
Is there any other linker/Compiler options available for this?
HI, all,
To optimize an algorith(coded by C) performance, I compiled the algorithm as a library with ARM compiler 6.
But another problem appears that the library will be called by older ARM compiler 5 project.
I want to know:
1) Whether Can ARM compiler…
I am trying to build a C++ OpenCV project with ARM compiler 6 in ARM development studio ide. I already, downloaded version 3.2.0 from the GitHub repository of OpenCV and built it for the MinGW compiler using CMake GUI in windows. When I configure my project…
Hi,
I have a strange issue, that on a bootloading project of mine worked if compiled with ARM Compiler 6.12 but did not if compiled with 6.13.1.
The function of the firmware is very simple: when it boots, it checks a (volatile) memory location for new…
I am trying to migrate an existing project from armcc to armclang using Keil. Most of the new errors generated by simply switching the compiler have been easily cleaned up with help from their migration guides. But I cannot seem to fix the following error…
I'm making XEN hypervisor being able to be built with ARM Compile 6 (6.6.3 in particular).
When built with GNU tools XEN hypervisor uses number of symbols defined in a linker script. E.g. [1].
Unfortunately, I did not find how to define symbols in…
I'm making XEN hypervisor being able to be built with ARM Compile 6 (6.6.3 in particular).
During the work, it was discovered a weird armclang compiler beahviour. When compiling a C file with only a data definition (no executable code, e.g. [1]), resulting…
I'm making XEN hypervisor being able to be built with ARM Compile 6 (6.6.3 in particular). While the hypervisor sources are compiled with armclang and linked with armlink into functional binary, some intermediate steps still require GNU toolchain.…
Hi,
We observe that there are several macros being defined in ARMCLANG. It would be helpful, if we know the meaning or purpose of these macros and will help us to use these macros judiciously:
[11864215]__arm64
[11864216]__arm64__
[11903057]__arm
[11903060…
Hi,
I'm working on SoC with ARM Cortex A9 processor and a CoreLink DMA-330 IP. The DMA controller has its own assembly instructions. My question is: How do I compile this DMA specific instruction set? DO I simply use the ARM Compiler (6) or do I need…
Hi;
I have built 'Compute Library' as said in Bare Metal Building section of documentation by using Linaro toolchain on Ubuntu. I'm targetting bare-metal.
On another machine, I want to use this library but this machine has an Arm Compiler…
Hello
While compiling Xen hypervisor with ARM DS 2019.0 (arm compiler 6.12) I am getting Internal fault: [0xe81a5a:6120001] with linker. Full build log attached.
Any pointers?

In the V5 to V6 compiler migration document is the following with respect to optimzations
-O0 No Optimization. Not recommended for use in ARM Compiler 6.6
-O1 Limited Optimization. This is currently the recommended level for source level debugging.
…I am using the ARM clang tool chain version 6.10.1.
The linker is showing the following warning:
Warning: L6776W: The debug frame in .debug_frame(CHostComm.o) does not describe an executable section.
I have no idea why this is coming or how to solve the…
I see that the lists of corrections / known defects in the release notes of each new compiler revision are tagged with a unique identifier (ex. SDCOMP-15294). Is it possible to find further information about these items such as steps to reproduce? Or…
Hi,
I was wondering if the V6 compiler (LLVM based) is free to use or it is required a license (uVision, DS-5, etc)?
Assuming my customer doesn't work with ARM tools (for example, Eclipse open OCD). Can he still work with V6 arm compilation tools?
…Hi, did Compiler 6 CLANG drop support for bit-banding for Cortex M3 and M4 ? I can't find any reference to such a feature.
Thank you,

I downloaded the DS-5 community to build my OS on ARM cpus but I don't have a free compiler for C so i downloaded the ARM c compiler 6 but can't work for no license . now what do i do ? i need help
