musl/src/string/arm, branch v1.2.5 musl - an implementation of the standard library for Linux-based systems add big-endian support to ARM assembler memcpy 2020-06-25T23:11:13+00:00 Andre McCurdy armccurdy@gmail.com 2020-01-21T18:52:15+00:00 9dce93ac7f7a76978b70581c6f073f671b583347 Allow the existing ARM assembler memcpy implementation to be used for both big and little endian targets.

add thumb2 support to arm assembler memcpy 2020-01-16T20:44:26+00:00 Andre McCurdy armccurdy@gmail.com 2019-09-13T18:44:31+00:00 91e662d1d941215eb024787db5e910dbfb5b169f For Thumb2 compatibility, replace two instances of a single instruction "orr with a variable shift" with the two instruction equivalent. Neither of the replacements are in a performance critical loop.

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.

disable use of arm memcpy asm if building as thumb code 2016-12-18T00:39:28+00:00 Rich Felker dalias@aerifal.cx 2016-12-18T00:39:28+00:00 9067a3006ea2f84395ab23a1dd30191387312e0c the thumb incompatibilities in the asm are probably only minor and should be fixable, but for now just use the C version.

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.
