musl/src/string/arm/__aeabi_memset.c, branch v1.2.6 musl - an implementation of the standard library for Linux-based systems fix arm run-time abi string functions 2017-06-22T22:34:06+00:00 Szabolcs Nagy nsz@port70.net 2017-02-21T00:07:34+00:00 e6def544358afd5648a428d2e02c147a1f901048 in arm rtabi these __aeabi_* functions have special abi (they are only allowed to clobber r0,r1,r2,r3,ip,lr,cpsr), so they cannot be simple wrappers around normal string functions (which may clobber other registers), the safest solution is to write them in asm, a minimalistic implementation works because these are not supposed to be emitted by compilers or used in general.

move arm-specific translation units out of arch/arm/src, to src/*/arm 2016-01-22T00:02:21+00:00 Rich Felker dalias@aerifal.cx 2016-01-22T00:02:21+00:00 e617b9eea9d45b170eabadf5ca96ca0536c538be this is possible with the new build system that allows src/*/$(ARCH)/* files which do not shadow a file in the parent directory, and yields a more logical organization. eventually it will be possible to remove arch/*/src from the build system.
