      make arch __clone backends hidden · f5f7673d
      Rich Felker 提交于
      these are not a public interface and are not intended to be callable
      from anywhere but the public clone function or other places in libc.

      explicitly assemble all arm asm sources as UAL · 4e73d121
      Rich Felker 提交于
      these files are all accepted as legacy arm syntax when producing arm
      code, but legacy syntax cannot be used for producing thumb2 with
      access to the full ISA. even after switching to UAL, some asm source
      files contain instructions which are not valid in thumb mode, so these
      will need to be addressed separately.

      remove non-working pre-armv4t support from arm asm · 9f290a49
      Rich Felker 提交于
      the idea of the three-instruction sequence being removed was to be
      able to return to thumb code when used on armv4t+ from a thumb caller,
      but also to be able to run on armv4 without the bx instruction
      available (in which case the low bit of lr would always be 0).
      however, without compiler support for generating such a sequence from
      C code, which does not exist and which there is unlikely to be
      interest in implementing, there is little point in having it in the
      asm, and it would likely be easier to add pre-armv4t support via
      enhanced linker handling of R_ARM_V4BX than at the compiler level.
      
      removing this code simplifies adding support for building libc in
      thumb2-only form (for cortex-m).

      clone: make clone a wrapper around __clone · fdf5f1b1
      Bobby Bingham 提交于
      The architecture-specific assembly versions of clone did not set errno on
      failure, which is inconsistent with glibc.  __clone still returns the error
      via its return value, and clone is now a wrapper that sets errno as needed.
      The public clone has also been moved to src/linux, as it's not directly
      related to the pthreads API.
      
      __clone is called by pthread_create, which does not report errors via
      errno.  Though not strictly necessary, it's nice to avoid clobbering errno
      here.

      initial commit of the arm port · d960d4f2
      Rich Felker 提交于
      this port assumes eabi calling conventions, eabi linux syscall
      convention, and presence of the kernel helpers at 0xffff0f?0 needed
      for threads support. otherwise it makes very few assumptions, and the
      code should work even on armv4 without thumb support, as well as on
      systems with thumb interworking. the bits headers declare this a
      little endian system, but as far as i can tell the code should work
      equally well on big endian.
      
      some small details are probably broken; so far, testing has been
      limited to qemu/aboriginal linux.
