I tried doing the same sometime back for the same need. I had to abandon it because CLZ seems to be added only in ARMv5. And at least one ARMv7 SoC uses -march=armv4 while building.
Does this setting make any sense, or should we fix that?
Looks like it makes sense. Here is what the comment says in arch/arm/cpu/armv7/tegra2/config.mk
# Use ARMv4 for Tegra2 - initial code runs on the AVP, which is an ARM7TDI. PLATFORM_CPPFLAGS += -march=armv4
Even if we could fix this, Rob is adding the API for all 'arm', which I feel is not correct.
best regards, Aneesh
