Version

5.8.2

Description

Somehow we are back to a broken build on ppc in 5.8.2 (at least 5.8.0 worked fine with the same toolchain). wolfcrypt/src/port/ppc32/ppc32-sha256-asm.S fails to compile with numerous syntax errors (see below).

Reproduction steps

Run the build on Darwin powerpc.

@SparkiDev Could we have this fixed for macOS, please? If it is a matter of prefixing registers and [conditionally] excluding unsupported mnemonics, I can handle that, but we need to decide whether separate files are used or not.

Hello @barracuda156 ,

My name is Anthony; I think I've helped you in the past. I will assign this to @SparkiDev and will make sure he is aware of this bug report via internal channels. Please stay tuned.

Warm regards, Anthony

Hi @barracuda156,

Are you able to use the inline assembly file: ppc32-sha256-asm_c.c?

@SparkiDev Thank you for responding. I don’t think it will compile, since registers are still unprefixed, but I will verify and let you know.

Hi @barracuda156,

Please try using -fomit-frame-pointer to mitigate this issue.

Hi @barracuda156 ,

Thanks for confirming -fomit-frame-pointer did not help. The register 31 should be allowed use, so we will look into it.

I noticed -Os and -O2 in your compiler flags. Have you tried with just one and does it build with any other optimization levels?

The failure is with the assembly version of the code that was introduced. For now you can add --disable-ppc32-asm to use the pure C version. The assembly version is about 10% faster, but not required.

If you want to use the assembly version I am curious if the small version works? --enable-ppc32-asm=WOLFSSL_PPC32_ASM_SMALL or WOLFSSL_PPC32_ASM_SMALL?

Note: Sean will be away for a week, so he'll look at this when he returns.

Thanks, David Garske, wolfSSL

@dgarske Is there some direct test to verify if an implementation – assuming it builds – is working as intended? I mean, specifically for this file. Fixing syntax in .S file for Darwin conventions will likely allow it to build. (In practice it should either be in parallel to Linux one or in the same file, but using conditional macros.) That won’t guarantee it will do what it should though. So a quick specific test would be helpful.

barracuda156 avatar Jul 22 '25 15:07 barracuda156

Hi @barracuda156 ,

Yes after the build run ./wolfcrypt/test/testwolfcrypt or make check. The wolfCrypt test runs test vectors for all algorithms.

Thanks, David Garske, wolfSSL

Hi @barracuda156 ,

Have you been able to work through these issues? If not please share an update and we can assist.

Thanks, David Garske, wolfSSL

dgarske avatar Sep 12 '25 16:09 dgarske

@dgarske @SparkiDev If someone could take a look at the issue again, it will be great. It is still relevant. (And thank you for reminding about it.)

barracuda156 avatar Sep 16 '25 13:09 barracuda156

Hi @barracuda156,

The PPC32 SHA-256 assembly code has been updated with the PR: #9508 When __PIC__ is defined, the new implementation will be used that doesn't use registers 30 or 31.

Let me know if this works for you!

Sean
