S32 Design Studio GCC VLE 4.9.4 doesn't support e_stmvmcsrrw opcode

[hli174]

Hi All,

I am trying to compile one file with GCC which is from S32DS. but I got an error Error: unrecognized opcode: `e_stmvmcsrrw'. I checked the source of that NXP GCC compiler and found that ppc-opc.c doesn't have this opcode which surprised me. Is there updated version GCC for MPC574XG target? or any suggestions for the work around? Thank you and I appreciate your help!

Hi, 

you can try use this patch:

Alexander Fedotov - Re: VLE load/store multiple instructions  

What is your S32DS Version?

Hi Jiri,

Thanks for your reply , I found that patch and I found the source of the compiler here :https://community.nxp.com/external-link.jspa?url=https%3A%2F%2Fwww.nxp.com%2Flgfiles%2Fupdates%2FS32... 

but there is no build script of the compiler in the source package. Just the patches and source tar package. Do you know where can I get the build script or build guideline? Without build script , I have no idea about how to configure each package. 

I am using this version :

S32 Design Studio for Power Architecture

Version: 2.1
Build id: 190624

Thank you!

No need to rebuild everything. You can download latest binutils release tarball from sourceware and build with target triplet "powerpc-eabivle"

Hi Alex,

Thank you for your reply. I saw 11 patches for binutils from NXP GCC package. Do you think the mainstream already has all changes? another word if I create a GCC from latest releases code will work in MPC574XG?

I searched the community and found this post, PowerPC VLE GCC: Sourcecode? , From Stepan K 's comments, looks like all NXP patches are not in mainstream of GCC toolchain.

Thanks!

Hi Hai,

Since your original issue is about missing instructions that Assembler complaints you'll need to build only assembler/objdump from the latest binutils. All binutils patches are in main line (except GDB patches). No need to build GCC from the scratch.

Regarding GCC patches streaming up I don't think this will happen in near future.

BTW, what is your OS ? Linux or Windows ? Maybe someone had already build the tools and and can share them.

Hello  Alex,

I also meet the same issue when I compile S32R294 with powerpc-eabivle-4_9, which is from the S32DS installation path.

I saw there some  patches for this issue. But I don't know how to add those  patches to my local powerpc-eabivle-4_9 compiler. How should I do to get a local powerpc-eabivle-4_9 compiler with those patches for this issue?

S32 Design Studio for Power Architecture

Version: 2.1
Build id: 190624

Thank you 

Best regards

Hi Alexander,

Thank you so much for your help, I used your commit to fix this issue sourceware.org Git - binutils-gdb.git/commit . I just add {"e_stmvmcsrrw",       OPVUPRT(6,17,7),OPVUPRT_MASK,   PPCVLE, 0,              {D8, RA0}}, in /opcodes/ppc-opc.c. I realize that you did that commit for the community you used the same avatar :smileyhappy: . I recompiled the gas , now the compilation error is going away. When I got the binary I will test it in real hardware. Thanks again and have a great weekend!
