The patch below fixes a bug in the new ARM _ld_linux_resolve implementation. I'm don't know if/how the current implementation was tested, but it's completely broken. This patch makes the prologue and epilogue agree on how big the stack frame is, and also makes sure EABI doubleword stack alignment is preserved. Tested on arm-linux-gnueabi.
2006-11-10This change reimplements the ARM _dl_linux_resolve entry point - this isEric Andersen
called to resolve DLL PLT entries. The assembler is changed to be thumb compatible and slightly faster, the C function, _dl_linux_resolver (note the extra r) is changed to take a byte address in place of an 8 byte count (faster in caller and callee, and slightly easier to understand).
2006-11-10arm thumb:Eric Andersen
Put the call_via_rx code into each executable - call_via_ip cannot possibly work if called through the PLT! ldso requires this code too as it is not linked with the crt stuff and thumb ldso does make calls via a register. The patch puts the code into crti.S so that it is linked into every normally built application (if thumb or interworking is selected). This is only 30 extra bytes and it works - the previous code did not because nothing both implemented and exported the APIs (they were in libgcc, but not in the version script). crti.S and crtn.S is also brought up to date with GCC 3.4.4 - this is essential for thumb support because the .init and .fini sections must use arm or thumb code to match the compilation of the libraries. Note that code which pushes stuff into .init or .fini must be compiled with or without -mthumb to match the uclibc compilation - and gcc itself (which does do this) must therefore be compiled to match.

This introduces a new SEND_EARLY_STDERR macro that is to be used in dl-startup.c before ld.so is relocated. It is needed on Blackfin (and frv) FDPIC since we have to use special tricks to get the address of a string constant. EARLY_STDERR_SPECIAL gets defined on such a machine and prevents printing of debug strings inside the loop that relocates ld.so, since we can't decide which of the two variants to use.
