81f1133174 ELF64 support (#220) 
* include: Introduce elf64.h and elf.h

    Added elf64.h for 64bit ELF support and moved common definitions
    from elf32.h to elf.h. Also introduced Elf_xxx to be used in
    common libraries such as binfmt.

  * binfmt, include, modlib, module: Add support for ELF64

    Elf_xxx must be used instead of Elf32_xxx to support ELF64.
    To use ELF64, CONFIG_ELF_64BIT must be enabled.

  * binfmt, modlib: Add support for relocate address

  * arch: risc-v: Add include/elf.h

  * libs: machine: Add risc-v related files.

    NOTE: Currently only supports ELF64

  * boards: maix-bit: Add elf and posix_spawn configurations

  * boards: maix-bit: Add support for module configuration

6a3c2aded6 Fix wait loop and void cast (#24) 
* Simplify EINTR/ECANCEL error handling

1. Add semaphore uninterruptible wait function
2 .Replace semaphore wait loop with a single uninterruptible wait
3. Replace all sem_xxx to nxsem_xxx

* Unify the void cast usage

1. Remove void cast for function because many place ignore the returned value witout cast
2. Replace void cast for variable with UNUSED macro

da1a561b6e binfmt/libelf/libelf_bind.c: Make naming of internal type compliant with coding standard. Yes, the ELF32 types do not follow the standard for historical reasons (and will be fixed someday), but let's not perpetuate the naming violation. 2019-03-20 09:34:08 -06:00

095e28d45e binfmt/, binfmt/libelf/, include/nuttx, libs/libc/machine, libs/libc/modlib, and others: Move elf related arch function to include/nuttx/elf.h because the implementation is located in libs/libc/machine and in order to avoid the conflict with the 3rd party libraries and clean up the file inclusion: (1) Remove redundant elf32.h, (2) Remove nuttx/binfmt/elf.h in libs/libc/machine, (2) Remove nuttx/binfmt/elf.h in modlib, and (4) Rmove nuttx/module.h in modlib. 2019-01-26 11:18:45 -06:00

241a7e17bd addrenv interface changes: up_addrenv_create() may need to create .text and .bss/.data separately because of differing access privileges (read/execute vs read/write). And, as a consequence, up_addrenv_vaddr() needs to be split into up_addrenv_vtext(0 and up_addrenv_vdata(). 2014-08-24 11:54:14 -06:00
