| | | | | | | | | | | | | In ARM asm code, ensure that every ENTRY(foo) has a matching END(foo). The EABI unwind info requires a .fnend for every .fnstart, and newer binutils will complain about seeing two .fnstart in a row. This change allows newer tools to compile our code. Do not generate unwind info in asm functions if _STANDALONE is defined. The .fnend op causes the assembler to emit RELOC references to unwind support functions that don't exist in libstand.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix various edge cases with rewinddir(), seekdir(), and telldir(): - In the unionfs case, opendir() and fdopendir() read the directory's full contents and cache it. This cache is not refreshed when rewinddir() is called, so rewinddir() will not notice updates to a directory. Fix this by splitting the code to fetch a directory's contents out of __opendir_common() into a new _filldir() function and call this from rewinddir() when operating on a unionfs directory. - If rewinddir() is called on a directory opened with fdopendir() before any directory entries are fetched, rewinddir() will not adjust the seek location of the backing file descriptor. If the file descriptor passed to fdopendir() had a non-zero offset, the rewinddir() will not rewind to the beginning. Fix this by always seeking back to 0 in rewinddir(). This means the dd_rewind hack can also be removed. - Add missing locking to rewinddir() - POSIX says that passing a location returned by telldir() to seekdir() after an intervening call to rewinddir() is undefined, so reclaim any pending telldir() cookies in the directory when rewinddir() is called. - If telldir() is called immediately after a call to seekdir(), POSIX requires the return value of telldir() to equal the value passed to seekdir(). The current seekdir code with SINGLEUSE enabled breaks this case as each call to telldir() allocates a new cookie. Instead, remove the SINGLEUSE code and change telldir() to look for an existing cookie for the directory's current location rather than always creating a new cookie. PR: 121656

The hcreate(3) implementation and related functions we inherited from NetBSD used to free() the key value, something that is not supported by the standard implementation.
