Subject: [ptxdist] How to add symbols to PTXDIST_LOWLEVEL_WRAPPER_BLACKLIST
Date: Mon, 13 Jul 2026 18:23:56 +0200	[thread overview]
Message-ID: <CABDcavZdMksUXhtF2-dyNTiFUkmw4A8MGQ2e86oropiw7SPfQQ@mail.gmail.com> (raw)

Hello,

Our BSP is currently defining:

TARGET_EXTRA_CFLAGS=-mtune=cortex-a7 -mfpu=neon-vfpv4

However this is causing us some trouble with TF-A, as the code
generated by the toolchain contains NEON instructions, which makes it
fail at runtime with "Undefined instruction" exceptions.

We could skip this for TF-A specifically by adding TARGET_EXTRA_CFLAGS
to TF_A_WRAPPER_BLACKLIST.

But actually we'd like to do the same for all low level code,
including kernel and bootloaders (U-Boot, OP-TEE). Since all of these
already set <package>_WRAPPER_BLACKLIST to
$(PTXDIST_LOWLEVEL_WRAPPER_BLACKLIST), the easiest and more robust way
would be to add TARGET_EXTRA_CFLAGS to
PTXDIST_LOWLEVEL_WRAPPER_BLACKLIST itself. Is this possible?

Thanks,

Guillermo Rodriguez Garcia
