Ah yes, great. > > Now, if we could move those three runtime checks from Makefile > to configure I will be completely unconditionally happy ;) > > - ifneq (,$(wildcard /lib/ld-linux.so.3)) > - ifneq (,$(wildcard /lib/ld-linux-armhf.so.3 > /lib/arm-linux-gnueabihf/ld-linux.so.3)) - $(if $(shell grep -l > "^Features.* \(vfp\|iwmmxt\) " /proc/cpuinfo),-DTCC_ARM_VFP) Now EABI and HARDFLOAT can be detected in configure by looking at the triplet: if it ends in eabi then it's just -DTCC_ARM_EABI, if it ends in eabihf then you also need to add -DTCC_ARM_HARDFLOAT. As to the other test, it just need to be moved to configure. Let's try that. > > (Of course I don't insist.
