Joseph Myers 5163b4b76f Fix MIPS mmap negative offset handling for consistency (bug 19550). ... The handling of negative offsets in MIPS mmap is inconsistent with other architectures, as shown by failure of the test posix/tst-mmap-offset for o32 and n32. The MIPS mmap syscall uses a signed argument and does a signed arithmetic shift on it, whereas the glibc semantics expected by that test are for the offset to be considered as a large positive offset. This patch makes MIPS consistent with other architectures as far as possible by using the mmap2 syscall on o32 (#including the generic implementation), and making mmap not an alias for mmap64 for n32, with a custom implementation for n32 that zero-extends the offset argument to 64-bit before calling the mmap syscall. Tested for MIPS64 (o32, n32, n64). [BZ #19550] * sysdeps/unix/sysv/linux/mips/mips32/mmap.c: New file. * sysdeps/unix/sysv/linux/mips/mips64/mmap64.c: Move to .... * sysdeps/unix/sysv/linux/mips/mips64/n64/mmap64.c: ... here. * sysdeps/unix/sysv/linux/mips/mips64/n32/mmap.c: New file. * sysdeps/unix/sysv/linux/mips/mips64/n32/syscalls.list (mmap64): New syscall entry. * sysdeps/unix/sysv/linux/mips/mips64/n64/syscalls.list (mmap): New syscall entry. * sysdeps/unix/sysv/linux/mips/mips64/syscalls.list (mmap): Remove syscall entry.		2016-02-01 18:20:21 +00:00
