* The attached patches fixes the problems found bringing up uclibc on coldfire Khem Raj2009-04-091-2/+2
| | | | | | | | | | | | | | M5485 processor 1. Disable mmap2() if we're compiling for coldfire and fall back to mmap(). It seems to map a different file area on a 2.6.25 linux kernel. 2. Uses pc-relative addresing[1], computes ADDR_ALIGN, PAGE_ALIGN and OFFSET_ALIGN relatively to _dl_pagesize[3]. On coldfire/M5485 _dl_pagesize is 0x2000.

| | | | | | | | | | | | | | | | | | | | I got the library to compile with the attached patches, though dynamic loader crashes early. In buildroot I changed the architecture name by hand from sparc to sparc64, otherwise the compiler produced 32-bit files with V9 (64-bit) instructions. This configuration is not supported by QEMU, so I aimed for pure 64-bit. I think Sparc64 option needs to be added to buildroot. The _Qp_ ops seem to be required by the ABI. This and setjmp patches are just hacks to get the compilation further. The _Qp_ ops can be found in glibc, would it be OK to use those? V9 assembler requires declarations for global register use. The mem* functions in sparc32 directory did not work. They are actually used only by the hybrid 32-bit + V9 CPU configuration.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Hello, I managed to get ldso (and thus shared linking to uClibc) to work on sparc (actually sparc64 kernel with 32-bit userspace), at least on simple "hello world" program (more complex ones not tested). Some notes on attached patch (against 0.9.26, would require some work to apply on current CVS - but I tested 0.9.26, not CVS): - ELF magic cannot be examined by _dl_strncmp so early, probably because of string constant, like on ppc/mips/sh (note that early SEND_STDERR still crashes when trying to do _dl_strlen - I suppose that string constants require relocation; but adding load_addr didn't help, just ELF header was displayed instead of crash) - mmap() is syscall6 like on ppc/mips/sh, not old i386 mmap() - for generic sparc (i.e. not sparcv8/sparcv9) gcc produces .udiv/.urem calls for unsigned integer / and % operators - so these operations must be avoided. I copied do_rem definition from arm header. But / and % are used also in _dl_simple_ltoa() and _dl_simple_ltoahex(); in ltoahex gcc optimizes it to shifts (but I think it's safer to use shifts explicitly, not rely on optimization...). I changed % in ltoa to do_rem, but as there was no do_div definition, I changed all "%d" specifiers to "%x" to avoid crashes (this changes wouldn't be needed if _dl_simple_ltoa() were fixed to not use division on sparc). - "#define SOLARIS_COMPATIBLE" in ld_sysdep.h broke ldso on Linux because of redefining _dl_linux_resolve only in some places (it was still referenced in INIT_GOT before redefinition). So _dl_linux_resolve redefinition should be moved before INIT_GOT definition or removed. - sparc64 kernel requires mmap() addresses to be aligned to 8192, not 4096, otherwise mmap() call failed - reloc_entry must be shifted by 10, not 12 (I found similar operation in glibc sources) Aside of sparc-specific fixes: - I moved some _dl_dprintf()s inside if(_dl_debug_*) conditions (to avoid debugging messages when LD_DEBUG is not defined) - it seems that there was possible off-by-one in ltoa and ltoahex? they are called with char[22] as 1st argument, and then '\0' is stored in local[22] (_before_ p decrementation)... or am I missing something? If not, fix is included in patch.
