| | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | In MIPS syscall(2), .cpload was added to an the error path, but it was not enough for ABIs other then O32. Use SETUP_GP, SETUP_GP64 and RESTORE_GP64 to handle all ABIs. This patch fixes an error path of MIPS pipe(2) too.

| | | | | | | | Hi All, this patch fixes a mismatch in ucontext struct between uClibc and kernel. In this way a signal handler installed by sigaction can access to the whole machine state correctly. This can be applied both to trunk and nptl branch

| | | | | | | | Current MIPS readahead(), posix_fadvise(), posix_fadvise64() do not match with kernel on all ABIs. On O32 ABI, a padding is needed before a long long argument. On N32/N64, a long long argument should be passed via a single register.

| | | | | | | | I actually suspect this code into the file uClibc/libc/sysdeps/linux/common/poll.c: tval.tv_nsec = (timeout % 1000) *1000; <==== make only usec! From milisecond this really needs a * 1000000 to make nanosecond. Without this a 1100 milisecond timeout is converted into a 1 seconde and 100 microsecond timeout! This can explain the weird result of the test code.

| | | | | | | running LTP test suite on uClibc-nptl for sh4 I found a bug into pread and pwrite functions. When the offset is negative it is not correctly handled due to a missing shift operation, so it is passed to the syscall as the highest unsigned positive value.

| | | | | | | | | On PowerPC, r13 is used for a small data pointer and needs to be set up from _SDA_BASE_ (defined by the linker) at startup. This is needed for the GCC testcase gcc.target/powerpc/980827-1.c to work. This patch fixes that testcase (verified for both static and dynamic linking).

| | | | | | | | | | | | | | | When I imported INLINE_SYSCALL, etc. from glibc, I just copied whole macros for each ABI. Actually, except for argument type (long vs. long long), internal_syscall[0-4] are identical for all ABI, and internal_syscall[5-6] for N32/N64 are identical for N32/N64. And I just disabled FORCE_FRAME_POINTER since it had caused build failure, but including <alloca.h> can solve it. Here is a patch to handle these issues, plus asm/__asm__ and volatile/__volatile__ conversion. Thanks for Peter S. Mazinger who did basic work of this cleanup.

* Atsushi Nemoto writes:Mike Frysinger2007-02-122-121/+164
| | | | | | | | | | Current ucontext_t does not match with kernel's definition. Also, on N32 ABI, we can not use kernel's struct sigcontext since kernel's sizeof(long) and user's sizeof(long) is differ. For both data structure, just importing header files from recent glibc fixes the mismatch. So here is a patch importing sys/ucontext.h and bits/sigcontext.t from glibc-2.5.

| | | | | | | | This patch imports INLINE_SYSCALL, etc. from glibc-2.5 ports and implements _syscall[0-7] by using them, like arm and powerpc. I think this patch does not change functionality, but gives better __SYSCALL_CLOBBERS for N32/N64.
