e596d5bd5e binfmt/libelf: Implement sh_addralign handling 
Basically, mirror the following two commits from modlib.
It's shame we have two copies of elf loaders.

```

    modlib: Implement sh_addralign handling

    I've seen a module with 16 bytes .rodata alignment for xmm operations.
    It was getting SEGV on sim/Linux because of the alignment issue.
    The same module binary seems working fine after applying this patch.

    Also, tested on sim/macOS and esp32 on qemu,
    using a module with an artificially large alignment. (64 bytes)
```

commit 418e11b8b3
Author: YAMAMOTO Takashi <yamamoto@midokura.com>
Date:   Thu Apr 15 11:33:48 2021 +0900

    modlib: Always use separate allocation for text and data

    Pros:

    * Reduce code differences
    * Smaller allocations for !CONFIG_ARCH_USE_MODULE_TEXT

    Cons:

    * Likely to use more memory for !CONFIG_ARCH_USE_MODULE_TEXT in total

    Tested with:

    * sim:module on macOS
    * esp32-devkit:nsh + CONFIG_MODULE on qemu
    * lm3s6965-ek:qemu-protected + CONFIG_EXAMPLES_SOTEST on qemu
```

468e08c1b4 binnfmt:Fix return before close ELF fd 
elf_init open a elf file , if both enabled
   CONFIG_NSH_BUIlTAPPS and CONFIG_NSH_FILE_APPS ,
   elf_init will read elf file in /bin directory, but
   that length is zero , elf_read failed return and NOT
   close elf fd, so this line MUST be return to errout_with_init

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

04f0ee5198 binfmt/: Change debug macro from berr() to binfo() when dumping module data. The report of problems is important during development but when it enables complete informative output about load binaries then the important information can be easily overlooked. The huge output sent to serial terminal slows loading significantly as well. 2019-08-15 14:41:42 -06:00

264a7164bc binfmt/: If there is an address environment (CONFIG_ARCH_ADDRENV), binfmt/elf doesn't need to free ctor/dtor alloc since freeing the address environment releases the heap automatically. 2019-01-26 11:29:08 -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
