gcc-4.7.2 arm-eabi multilibs

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello,

Why are the multilibs so limited for the default build with a target of arm-eabi ?

The compiler supports '-march=armv7-m -mthumb' how-ever this leads to ld [1] emitting 'blx' instructions when accessing libgcc functions and the 'blx' instruction is not supported on Cortex-3M processor I am using.

Looking in gcc/config/arm/t-arm-elf I see a number of commented options.

Thanks
Chris
