2024-02-29Add time64 support for sparc.Dmitry Chestnykh
By some reason sparc ld.so cannot work properly with statx() system call, so fallback to regular stat() family in ld.so. Signed-off-by: Dmitry Chestnykh <dm.chestnykh@gmail.com>

Similar to glibc commit https://sourceware.org/git/?p=glibc.git;a=commit;h=6bbfc5c09fc5b5e3d4a0cddbbd4e2e457767dae7 we need to handle Linux kernel change, which removed stat64 family from default syscall set.

2018-08-10Fix bug in _dl_pread when using pread64 syscallChristophe Lyon
In ARM_EABI mode, the pread64 syscall parameters are aligned on 64-bits. This syscall is used in rtld when processing FDPIC relocations. * ldso/include/dl-syscall.h (__syscall_pread): Fix definition. (__dl_pread): Fix syscall invocation. * ldso/ldso/fdpic/dl-sysdep.h (__DL_PREAD): Handle __NR_pread64.

For avr32 we still use gcc 4.4 compiler, so exlude the usage of __builtin_unreachable here.

2015-03-26ldso: mark _dl_exit as noreturnBernhard Reutner-Fischer
Otherwise gcc might not understand that oom() ended control-flow and might emit an (untaken) reference to abort() in _dl_update_slotinfo() on e.g. SH4 which breaks linking ld-uClibc.so. Arguably -ffreestanding should prevent GCC from emitting this '.global abort' but alas, it does not, which is another bug.. Also mark the function cold to further lower the incoming frequency and branch probability. Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>
2015-01-25add support for $ORIGINWaldemar Brodkorb
This is for example required, used and tested with OpenJDK 7. No regressions found, while running the testsuite with embedded-test.

Remove leftover code.

2009-04-09The attached patches fixes the problems found bringing up uclibc on coldfire Khem Raj
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.

2007-12-03Some versions of gcc consider inline merely a hint. AVR32 depends on theCarmelo Amoroso
system calls actually being inlined, so AVR32 needs to use __always_inline instead of just inline. The attached patch changes this for the system calls. Signed-off-by: Hans-Christian Egtvedt <hcegtvedt@atmel.com>

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.
