config BR2_PACKAGE_VALGRIND_ARCH_SUPPORTS
        bool
        default y if BR2_aarch64

So, yes, Valgrind can be enabled on AArch64 in Buildroot 2019.02.

Why do you ask this question ? Did you try and encountered an issue ?

Best regards,

Thomas

Hi Thomas,
               Thanks for your reply.
I am running a aarch64 platform with userspace  in 32 bit mode, so probably
the reason for valgrind not shown in that list is the BR2_arm was not
exist  in config BR2_PACKAGE_VALGRIND_ARCH_SUPPORTS .

 After added the below line, i am able to choose valgrind support as part
of my target package.  But i got below build error

checking for a supported CPU... no (arm)
configure: error: Unsupported host architecture. Sorry

valgrind-3.14.0 is what the version configured to use in valgrind.mk. I am
not sure if this particular version will support arm32.

config BR2_PACKAGE_VALGRIND_ARCH_SUPPORTS
        bool
        default y if BR2_aarch64
       + default y if BR2_arm
        default y if BR2_ARM_CPU_ARMV7A
        # MIPS32 R6 is unsupported
        default y if BR2_mips && !BR2_mips_32r6
        default y if BR2_mipsel && !BR2_mips_32r6

Thanks,
Ravi

                       ^^^^^^^^^^^^^^^^^^
 As you can see, valgrind does support arm32, but only ARMv7-A (i.e. Cortex-A
class CPUs).

 It might also support ARMv8 in 32-bit mode, however. Note that you'll need to
adapt the rewriting of GNU_TARGET_NAME in valgrind.mk if you want to try that.

 Regards,
 Arnout
