| | | | | | | This patch uses the HIDDEN_JUMPTARGET instead of the __GI_ prefix in AVR32 assembler files. This is done to follow the code style in uClibc. Signed-off-by: Hans-Christian Egtvedt <hcegtvedt@atmel.com>

* Chris Zankel writes:Mike Frysinger2008-01-0542-0/+2991
| | | | | | | | | | | | | | | | | | The following patches add support for the Xtensa processor architecture to uClibc. They are based on a recent SVN checkout (12/05/2007). The first patch (attached to this post) adds Xtensa support to various shared configuration and make files. The following patches then include the Xtensa specific files and directories. I welcome any feedback and would appreciate it if you could include the patches into the mainline tree. I am certainly committed to maintain the port. Bob Wilson was kind enough to review the patches. Some notes about the architecture: Xtensa is a configurable and extensible processor architecture developed by Tensilica. For more information, please visit: www.linux-xtensa.org.

* michael_d writes in #1874: Mike Frysinger2008-01-051-2/+2
| | | | | | | | | On an i386 platform with no rt_sigsuspend syscall (ie: Linux 2.0), compilation will halt on libc/sysdeps/linux/common/sigsuspend.os with a cryptic error message: "Error: non-constant expression in ".if" statement" I've investigated and found that the cause is that a literal '0' is being passed into a block of complex assembler macrology that is only prepared to deal with register names - '%eax', etc. In turn, that seems to be because of a typo in the GCC register constraints. The constraints for 2 and 3-argument syscalls includes a "C" constraint. To gcc, "C" means an SSE floating point constant -- an unlikely element in a syscall. I suspect the author meant to type "S" (%esi).

But on platformes with uClibc a zero timeout poll block until a file descriptor event occurs.

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

| | | | | | | | 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.

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.
