| | | | | | | | | | | | | | | | | | | | This patch adds code to uClibc to support a new ABI designed for the FR-V architecture, that enables text segments of executables and shared libraries to be shared by multiple processes on an OS such as uClinux, that can run on FR-V processors without an MMU. Patches for binutils and GCC have just been posted in the corresponding mailing lists. The binutils patch was approved, but there's one additional patch pending review, that I posted this week. An updated GCC patch will be posted to gcc-patches@gcc.gnu.org as soon as I complete testing (I used a known-good compiler to test the uClibc patch below). Since the existing dynamic loader code didn't support independent relocation of segments, it required changes that were somewhat extensive. I've added a number of new machine-specific macros to try to keep the platform and ABI-specific details outside the generic code. I hope this is not a problem.

| | | | | | | | | | While testing the FR-V code with GCC mainline, I ran into some problems in the RPC code. It relies on a GCC extension that is no longer available, namely, the result of a cast is no longer considered an lvalue. This patch enables the code to compile. I haven't been able to test RPC though, especially in a multi-threaded environment.

| | | | | | | | | | | | | | | | | | Hi it is me again. This is the latest ldso patch. the NEW weak symbol handling works now with a little special handling in _dl_find_hash(). You get to chose if you want the new or old handling :) There was 2 missing _dl_check_if_named_library_is_loaded() calls in _dlopen(). I then disabled the _dl_check_if_named_library_is_loaded() in dl-elf.c since it is rendundant. Question, why does some _dl_linux_resolver(), like i386, have 2 calls to _dl_find_hash()? I think that is wrong, isn't it? I really hope you can check this out soon ...

| | | | | | | | We can't use trapa #0xff on sh2, the only permissible trapa ranges are 32 to 63. On SH-2, we use trapa32 to issue a break in the same way that trapa #0xff is used on SH-3/4. This behavior is implementation specific, but is what is used in sh-ipl+g, linux, eCos, uITRON, etc. so we follow suit here.

* New stdio core. Should be more maintainable. Fixes a couple of bugs.Manuel Novoa III2004-02-11119-7767/+9224
| | | | | | | | Codepaths streamlined. Improved performance for nonthreaded apps when linked with a thread-enabled libc. Minor iconv bug and some locale/thread related startup issues fixed. These showed up in getting a gcj-compiled java helloworld app running. Removed some old extension functions... _stdio_fdout and _stdio_fsfopen.
