Dear ML,
I'm trying to build u-boot-v2 for an iMX27 based board. I'm getting a HW/SW floating point mismatch error and hope someone will point me to a solution. Building with: make ARCH=arm CROSS_COMPILE=arm-eabi- It works along fine until I get an error on each of these files: arch/arm/lib/_ashldi3.o arch/arm/lib/_ashrdi3.o arch/arm/lib/_divsi3.o arch/arm/lib/_modsi3.o arch/arm/lib/_udivsi3.o arch/arm/lib/_umodsi3.o arch/arm/lib/_lshrdi3.o arch/arm/lib/findbit.o arch/arm/lib/io-readsb.o arch/arm/lib/io-readsw-armv4.o arch/arm/lib/io-writesb.o arch/arm/lib/io-writesw-armv4.o
Error is:
arm-eabi-ld: ERROR: arch/arm/lib/_ashldi3.o uses hardware FP, whereas arch/arm/lib/built-in.o uses software FP arm-eabi-ld: failed to merge target specific data of file arch/arm/lib/_ashldi3.o
The source files are assembly, any C files have the -msoft-float compile option. What gives?
All our toolchains produce soft float by default, so this does not show up here. U-Boot does not use floating point, so I think we do not have to care what the compiler produces. Does it help to remove the -msoft-float from arch/arm/Makefile?
