Hi experts.

For managing binary file's version information.. I just want to Elf Header's e_version field...

But I don't know how to change that information on compile time...

Could  I use that field as i want to?

Cuz the some application…

How can I tell the linker/compiler not to use memset/memcpy function which use FPU registers?

For example: SCIOPTA allows to limit the use of the FPU for certain tasks (to improve task-switching). Tasks without FPU may not use FPU registers. But the compiler…

Hi Experts,

For Cortex R and M processors Linaro has recommended the GCC arm-none-eabi 4.9 whereas for A series processors it is recommending normal GCC eabi.

what is the key difference between the same ?

I'm interested in learning about what's under the hood, or what's hidden from you by an IDE, by which I mean, compiler, linker, makefiles - that type of thing. I have a few specific, if potentially misguided questions about what I think I should be doing…

Hi ARM experts,

I'm new to develop boorom with armv8 CPU. 

I have seen the example in ARM DS-5 .(startup_v8_ARMCompiler6)

But I have no idea which step is  essential .

Could you show me or tell me where I can find the related…

Hello ARM Community,

I am using DS-5 5.18.1. I have a C function which must be compiled inline to decrease latency of an FIQ handler. I referenced following document for syntax:

How to use GNU ARM binutils for cortex-M4? When I try to compile with -mcpu=cortex-M4 -march=armV7e-m I get 'bad value in switches'.

If a char parameter is passed to a routine in Aarch64 is the top of the word undefined? and is the same true for if a char value is returned? I think the answer is yes but it would be good to be certain. This means if the char is used in some arithmetic…

ARM compiler 6 is not compatible with 32- bit machines. How do i overcome this problem.

Hi All,

Can we configure r5 compiler to turn of using LDM instructions. I just want to use multiple LD instructions instead of one LDM.

Thanks in advance.

Hi,

I would like to crete assembly and binaries from c code, targeting arm v7 architecture.

I would like to use LLVM to do that. Is there any specific manual/documentation/website?

Thank you

Hello,

I would like to download the GCC compiler for ARMv7-A. I would like it to support thumb and NEON instructions. Where can I get the latest version?

Also, are there any other open source compilers that meet the above requirements?

Thanks

Hi all,

How about the GCC compiler support of ARM arch v8 has been given. Is it full fledged, with all the options provided by ARMCC or it needs to be updated yet in future. I mean support for armcc Vs gcc

Hi all,
