In order the enable the same set of features, we have to update several configure scripts that generally match targets like *-*-linux*: in most places, we add *-uclinux* where there is already *-linux*, or uclinux* when there is already linux*. In gcc/config.gcc and libgcc/config.host we use *-*-uclinuxfdpiceabi because there is already a different behaviour for *-*uclinux* target.

We also make sure to use the --fdpic assembler option, and select the appropriate linker emulation. At link time, we also default to -pie, unless we are generating a shared library or a relocatable file (-r). Note that even for static link, we must specify the dynamic linker because the executable still has to relocate itself at startup. We also force 'now' binding since lazy binding is not supported. We should also apply the same behavior for -Wl,-Ur as for -r, but I couldn't find how to describe that in the specs fragment. 2018-XX-XX Christophe Lyon Mickaël Guêné gcc/ * config.gcc: Handle arm*-*-uclinuxfdpiceabi. * config/arm/bpabi.h (TARGET_FDPIC_ASM_SPEC): New.

We have to disable tailcall optimizations if we don't know if the target function is in the same module. If not, we have to set r9 to the value associated with the target module. When generating a symbol address, we have to take into account whether it is a pointer to data or to a function, because different relocations are needed. 2018-XX-XX Christophe Lyon Mickaël Guêné * config/arm/arm-c.c (__FDPIC__): Define new pre-processor macro in FDPIC mode. * config/arm/arm-protos.h (arm_load_function_descriptor): Declare new function. * config/arm/arm.c (arm_option_override): Define pic register to r9.
