* Chris Zankel writes:Mike Frysinger2008-01-0562-2/+5055
| | | | | | | | | | | | | | | | | | The following patches add support for the Xtensa processor architecture to uClibc. They are based on a recent SVN checkout (12/05/2007). The first patch (attached to this post) adds Xtensa support to various shared configuration and make files. The following patches then include the Xtensa specific files and directories. I welcome any feedback and would appreciate it if you could include the patches into the mainline tree. I am certainly committed to maintain the port. Bob Wilson was kind enough to review the patches. Some notes about the architecture: Xtensa is a configurable and extensible processor architecture developed by Tensilica. For more information, please visit: www.linux-xtensa.org.

| | | | | | I noticed, that in libc/misc/syslog/syslog.c when the syslog socket is opened, the close-on-exec flag is not set, as it is in gnu libc. This enables that behavior.

| | | | | | | | I had occasion to look at the uClibc script "getent" and felt compelled to clean out the cargo-cult programming style. I believe that this version is clearer, and I've added some minor features while I was in there: * usage clause, if no arguments or "--help" requested * original version appears to have been intending to "exit 2" on failure to match, but didn't * basic, probably good enough, support for ethers and netgroups * faster ;-) [as if that matters for this script]

* michael_d writes in 1879:Mike Frysinger2008-01-051-1/+1
| | | | | | When no TIOCGPTN definition is present in the kernel headers, the library's ptsname() function will not work. The libc/stdlib/ptsname_r.c file is the problem. This file includes a complicated nest of #if directives. One of these #if's has the opposite sense from what is required.

* michael_d writes in #1874: Mike Frysinger2008-01-051-2/+2
| | | | | | | | | On an i386 platform with no rt_sigsuspend syscall (ie: Linux 2.0), compilation will halt on libc/sysdeps/linux/common/sigsuspend.os with a cryptic error message: "Error: non-constant expression in ".if" statement" I've investigated and found that the cause is that a literal '0' is being passed into a block of complex assembler macrology that is only prepared to deal with register names - '%eax', etc. In turn, that seems to be because of a typo in the GCC register constraints. The constraints for 2 and 3-argument syscalls includes a "C" constraint. To gcc, "C" means an SSE floating point constant -- an unlikely element in a syscall. I suspect the author meant to type "S" (%esi).

* Blackfin FD-PIC patch 6/6.Bernd Schmidt2007-12-043-51/+222
| | | | | | | These are mostly the changes necessary to deal with loading the libraries into memory. A couple new target macros are defined for this purpose, and the code in dl-elf.c is modified to deal with nommu systems.

* Blackfin FD-PIC patches 5/6.Bernd Schmidt2007-12-034-8/+35
| | | | | | | A couple more target macros for ld.so to deal with FD-PIC support. We need special code to compute the initial got and dpnt, and we need to pass extra arguments to _dl_get_ready_to_run.
* Blackfin FD-PIC patch 4/6.Bernd Schmidt2007-12-031-0/+7
| | | | Add a hash table for function descriptors on FD-PIC targets.
* Blackfin FD-PIC patch 3/6.Bernd Schmidt2007-12-036-14/+61
| | | | | | | | | | | | | | | Change _dl_find_hash to _dl_lookup_hash, as on the NPTL branch. _dl_find_hash is now a wrapper function around it; unlike on the NPTL branch, it retains the old interface so that not all callers need to be changed. _dl_lookup_hash can optionally give its caller a pointer to the module where the symbol was found. Introduce ELF_RTYPE_CLASS_DLSYM for lookups from libdl. Spelling fixes in the Blackfin port, since Alex Oliva's original version of these patches used _dl_find_hash_mod as the name of the function rather than _dl_lookup_hash.
* Blackfin FD-PIC patch 2/6.Bernd Schmidt2007-12-033-6/+33
| | | | | | Add the necessary changes in ld.so and libdl to deal with targets that prepend an underscore to symbol names.

| | | | | | | Add a new function _dl_free. In _dl_malloc, ensure we always get back a full page from mmap. Reset _dl_malloc_function and _dl_free_function when libdl is initialized.

* realpath: reduce stack usage from 3*PATH_MAX (12k) to 1*PATH_MAX (4k).Denis Vlasenko2007-12-031-34/+36
| | | | | | | | | reduction is achieved by direct use of user-supplied PATH_MAX sized buffer for result (without intermediate copy) and changes in copy_buf[] usage - now it is used for both "source" pathname and link name (it works because they have to be less than PATH_MAX combined, otherwise we return NULL).
